exam questions by topic 👇

Cognitive explanations of gambling addiction A-Level Psychology revision examines how irrational thoughts and biased interpretations can encourage persistent gambling. Gamblers may overestimate their chances of winning, believe they can control chance outcomes, remember wins more readily than losses or interpret a near miss as evidence that success is close.

You will learn how these cognitive biases may maintain gambling even when repeated losses occur. You will also evaluate whether distorted thinking causes addiction, results from gambling experience or interacts with reinforcement, personality and biological vulnerability. AQA requires cognitive theory applied to gambling, including cognitive bias.

Cognitive Explanations of Gambling Addiction A-Level Psychology Revision Focus

The cognitive approach explains behaviour through internal mental processes.

In gambling addiction, relevant cognitive processes include:

Beliefs.
Expectations.
Interpretations.
Memory.
Judgements about probability.
Perceptions of control.
Decisions about risk.
Explanations of wins and losses.

Cognitive theory proposes that gambling may continue because the person does not interpret chance outcomes accurately.

The gambler may:

Overestimate the probability of winning.
Underestimate the probability of losing.
Believe that a win is due.
Believe personal actions affect random outcomes.
Remember wins more easily than losses.
Reinterpret losses as evidence of being close to success.
Create explanations that protect the belief that continued gambling is worthwhile.

The AQA specimen mark scheme describes cognitive theory through irrational thinking, overestimates of winning, underestimates of the odds against winning, hindsight bias and irrational statements made during gambling.

What Is a Cognitive Bias?

A cognitive bias is a systematic error in thinking that affects how information is:

Noticed.
Interpreted.
Remembered.
Used in decisions.

A bias is not simply a lack of intelligence.

It is a consistent tendency to process information in a particular distorted way.

In gambling, cognitive biases may distort understanding of:

Chance.
Probability.
Skill.
Control.
Previous outcomes.
Near misses.
Personal success.

AQA’s November 2020 mark scheme identifies cognitive biases as distorted understandings of chance outcomes.

A General Cognitive Sequence

The cognitive explanation may be represented as:

Gambling event → biased interpretation → increased expectation of reward → decision to continue gambling → further wins and losses → biases strengthened or maintained

For example:

A gambler loses five times.
They think, “A win must be due.”
They believe the next bet has an improved chance.
They continue gambling.
An occasional later win appears to confirm the belief.
The distorted expectation becomes stronger.

The belief influences behaviour even though the previous losses may not have changed the probability of the next independent outcome.

Irrational Thinking

What Is Irrational Thinking?

Irrational thinking involves conclusions that are not supported by accurate evidence or probability.

Examples include:

“The machine owes me a win.”
“I have lost so often that winning is now inevitable.”
“My lucky shirt changes the outcome.”
“I can sense which number will appear.”
“The machine nearly paid out, so I should continue.”
“I usually win because the losses do not really count.”
“My knowledge guarantees that this bet is safe.”

These thoughts may encourage:

Larger bets.
Longer gambling sessions.
Chasing losses.
Returning after an attempt to stop.
Ignoring overall financial harm.

Overestimating the Probability of Winning

A gambler may believe that winning is more likely than it really is.

This may occur because:

Wins are memorable.
Advertisements emphasise winners.
Near misses feel significant.
The gambler believes in personal skill.
Previous occasional wins appear to confirm future success.
Losses are dismissed or forgotten.

For example:

A gambler remembers three successful bets but gives little attention to dozens of unsuccessful ones.

Their subjective estimate of success becomes distorted.

Underestimating the Probability of Losing

The gambler may also underestimate:

How frequently losses occur.
The total amount lost.
The long-term financial risk.
The possibility that gambling will continue without a major win.

The person might focus on individual small wins rather than calculating the overall outcome.

For example:

“I won £40 yesterday.”

This statement may ignore that the person spent £100 obtaining the win.

The cognitive bias affects how the outcome is represented mentally.

The Gambler’s Fallacy

What Is the Gambler’s Fallacy?

The gambler’s fallacy is the mistaken belief that a run of one outcome makes the opposite outcome more likely next.

For example:

“Red has appeared five times, so black must be due.”

or:

“I have lost repeatedly, so my next bet is more likely to win.”

AQA’s November 2020 mark scheme describes this as a perceptual bias in which the gambler believes that a run of losses must be followed by a win.

Independent Outcomes

In many chance-based forms of gambling, each outcome is independent.

This means that the result of an earlier event does not alter the probability of the next event.

For example, several previous roulette outcomes do not make the opposite colour automatically due.

The gambler’s fallacy incorrectly treats chance as though it must correct itself over a short sequence.

The Law of Small Numbers

The gambler may expect a short sequence to reflect the balance expected across a much larger number of events.

For example:

“There have been too many losses, so the next result must balance the sequence.”

This expectation is inaccurate because short sequences can contain repeated similar outcomes.

The gambler expects chance to look more orderly than it really is.

Gambler’s Fallacy and Continued Gambling

The process may be:

The gambler experiences several losses.
The losses are interpreted as increasing the probability of a win.
The person believes stopping now would mean missing the predicted reward.
Another bet is placed.
Continued gambling produces further losses or an occasional win.
If a win occurs, it is remembered as confirmation that persistence worked.

This bias can make losing a reason to continue rather than a signal to stop.

Applying the Gambler’s Fallacy

After losing six times, Sanjay says, “This is perfect. I cannot lose again because a win has to come next.”

This shows the gambler’s fallacy because:

Sanjay believes previous losses alter the next outcome.
He assumes chance must correct the sequence.
The belief encourages another bet.
The losses are interpreted as evidence for future success.

Gambler’s Fallacy and Variable Reinforcement

The gambler’s fallacy is different from variable reinforcement.

Variable reinforcement

Rewards are delivered unpredictably.

Gambler’s fallacy

The gambler incorrectly believes that earlier losses make the next win more likely.

The two may interact:

Unpredictable wins teach the gambler that rewards sometimes follow losses.
The gambler then develops the mistaken belief that enough losses make a win due.

This connects with partial and variable reinforcement in gambling.

Illusion of Control

What Is the Illusion of Control?

The illusion of control is the belief that a person can control or predict an outcome that is substantially determined by chance.

AQA describes this as control bias, where the gambler believes outcomes can be predicted or controlled.

The gambler may believe that their:

Choices.
Movements.
Timing.
Confidence.
Concentration.
Method.
Personal qualities.

influence a random outcome.

Examples of Illusion of Control

A gambler might believe:

Pressing a button at exactly the right moment changes a slot-machine outcome.
Throwing dice gently produces a low number.
Throwing dice forcefully produces a high number.
Selecting their own lottery numbers improves the chance of winning.
Sitting at a particular machine increases success.
Concentrating intensely affects the result.
A personal system can predict random events.

Choice and Control

Being allowed to choose may increase the person’s sense of control.

For example, a gambler may prefer:

Selecting their own lottery numbers.
Choosing a particular machine.
Deciding when to press a button.
Throwing the dice personally.

The opportunity to choose can create the feeling that skill or personal agency affects the outcome.

However, choice does not necessarily change the underlying probability.

Illusion of Control and Persistence

The process may be:

The gambler believes their actions influence the outcome.
A win is attributed to personal control.
A loss is attributed to poor timing, distraction or an unusual event.
The underlying belief in control remains protected.
The gambler tries again using a slightly altered strategy.
Gambling continues.

The bias makes the gambler feel that improved performance can create future success.

Ritual Bias

What Is Ritual Bias?

Ritual bias is the belief that a repeated action, object or routine can influence a chance outcome.

AQA gives the example of blowing on dice as a lucky ritual.

Possible rituals include:

Wearing lucky clothing.
Choosing a lucky seat.
Touching an object before betting.
Using a particular number.
Entering the game at a specific time.
Repeating a phrase.
Performing the same action before each spin.

How Ritual Bias Develops

A ritual may become associated with winning by coincidence.

For example:

A gambler wears a particular shirt.
They win while wearing it.
The shirt becomes associated with the win.
The gambler attributes success to the shirt.
The ritual is repeated.
Later wins are noticed as confirmation.
Losses while using the ritual are dismissed.

The belief may become resistant to contradictory evidence.

Ritual Bias and Illusion of Control

Ritual bias is one form of illusion of control.

The gambler believes that a personal action influences a chance-based event.

However, ritual bias focuses specifically on:

Lucky behaviours.
Objects.
Routines.
Superstitions.

Applying Ritual Bias

Before every online bet, Keira taps the screen three times because she believes this makes a winning result more likely.

This demonstrates ritual bias because:

The tapping has no demonstrated causal connection with the result.
Keira believes the ritual controls chance.
Performing it may increase confidence.
The belief encourages continued gambling.

Skill Bias

What Is Skill Bias?

Skill bias is the mistaken belief that personal knowledge or ability provides more control over a gambling outcome than it actually does.

AQA gives examples such as:

Choosing lottery numbers.
Believing one can select a winning horse.

The gambler may believe that they possess:

Exceptional knowledge.
Superior judgement.
A special system.
Intuition.
An ability to detect patterns.
Greater expertise than other gamblers.

Games of Skill and Games of Chance

Some gambling activities contain genuine skill components.

For example, knowledge may affect certain decisions within:

Card games.
Sports betting.
Horse-racing analysis.

However, skill may still be overestimated because:

Outcomes remain uncertain.
Opponents also possess skill.
Unexpected events occur.
The gambler selectively remembers successful predictions.
Confidence may exceed actual accuracy.

The cognitive bias is not the claim that skill never matters.

It is the excessive belief that personal skill guarantees or strongly controls uncertain outcomes.

Skill Bias in Lotteries

Choosing a lottery number may create ownership and confidence.

The gambler might believe:

“My numbers are better because I selected them carefully.”

However, personally meaningful numbers do not automatically have a greater chance of being selected.

The act of choosing creates a feeling of expertise without changing the chance process.

Skill Bias and Attribution

A gambler may make self-serving attributions:

Win: “My skill caused it.”
Loss: “It was bad luck.”
Near miss: “My method was nearly correct.”

This protects confidence and encourages continued gambling.

Selective Recall

What Is Selective Recall?

Selective recall occurs when a gambler remembers wins more readily than losses.

AQA also refers to this as availability bias.

The memories most easily recalled influence the gambler’s judgement.

If winning experiences are vivid and emotionally powerful, the person may conclude that winning is more frequent than it really is.

Why Wins May Be Memorable

Wins may involve:

Strong excitement.
Celebration.
Praise from friends.
A visible payout.
A memorable story.
Relief after losses.
Repeated discussion.

Losses may be:

Similar to one another.
Emotionally uncomfortable.
Avoided.
Forgotten.
Described as temporary setbacks.

Availability Bias

The availability heuristic involves judging probability according to how easily examples come to mind.

For example:

“I can remember several big wins, so I must be a successful gambler.”

The person uses accessible memories rather than a complete record.

Selective Recall and Financial Judgement

A gambler may remember:

The amount won on successful occasions.

while forgetting:

The number of losing bets.
The money spent reaching the win.
Previous debts.
The total long-term outcome.

This can create an unrealistically positive view of gambling success.

Applying Selective Recall

Arlo often tells friends about the two occasions when he won large amounts. He says he is usually successful but cannot remember how much he has lost during the rest of the year.

This shows selective recall because:

Winning experiences are easily retrieved.
Losses receive less attention.
His estimate of success is based on incomplete evidence.
The bias may encourage continued gambling.

AQA’s June 2024 mark scheme similarly applied CBT to a gambler who talked about wins, ignored losses and believed he possessed special skill.

Near-Miss Bias

What Is a Near Miss?

A near miss is an outcome that is objectively a loss but appears close to a win.

Examples include:

Two matching slot-machine symbols with the third almost matching.
A selected number being next to the winning number.
A horse finishing second by a small margin.
Missing one item needed for a prize.
A card hand being one card away from success.

What Is Near-Miss Bias?

Near-miss bias, also called near-win bias, occurs when a gambler interprets a near miss as evidence of almost succeeding rather than as a loss.

AQA states that a gambler may perceive a near-miss loss as a near win.

Why Near Misses Encourage Gambling

A near miss may create thoughts such as:

“I was nearly there.”
“My strategy is improving.”
“The machine is about to pay.”
“One more attempt should work.”
“I almost predicted it correctly.”

The person treats closeness as meaningful evidence of future success.

Objective and Subjective Outcomes

Objectively:

The gambler lost.

Subjectively:

The gambler feels close to winning.

The distorted interpretation may produce motivation similar to a reward.

Applying Near-Miss Bias

A slot machine displays two jackpot symbols and a third symbol immediately above the winning line. Mina says, “That proves the machine is nearly ready to pay out.”

This shows near-miss bias because:

The result is a loss.
Mina interprets it as progress.
She believes closeness predicts a future win.
The belief encourages continued play.

Near Misses and Learning Theory

Learning theory treats a financial win as reinforcement.

Cognitive theory explains why an objective loss may also encourage continued gambling.

A near miss may not provide money, but the gambler’s interpretation gives it motivational value.

This is one area where cognitive theory may explain persistence that reward alone cannot fully explain.

Hindsight Bias and Post Hoc Rationalisation

What Is Hindsight Bias?

Hindsight bias occurs when a person believes, after an event, that the outcome was predictable.

The gambler may reconstruct their previous thinking and claim:

“I knew that horse would win.”
“I could tell the machine was ready.”
“I had a feeling that number would appear.”
“My system predicted it.”

The AQA specimen mark scheme identifies hindsight bias through post hoc rationalisations.

Post Hoc Rationalisation

Post hoc means after the event.

A post hoc rationalisation is an explanation created after the outcome is known.

For example:

After winning, the gambler identifies several signs that supposedly predicted success.

The gambler may ignore occasions when the same signs were present but no win occurred.

How Hindsight Bias Maintains Gambling

A random win occurs.
The gambler constructs an explanation for why it was predictable.
Confidence in personal judgement increases.
Future gambling appears less uncertain.
The person continues or increases their bets.

The bias transforms a chance outcome into apparent evidence of skill.

Confirmation Bias

What Is Confirmation Bias?

Confirmation bias is the tendency to notice and remember evidence supporting an existing belief while ignoring contradictory evidence.

Although AQA’s mark scheme does not name confirmation bias separately, it is closely connected to the listed biases of selective recall, skill bias and ritual bias.

For example, a gambler who believes in a lucky number may:

Remember every time it wins.
Ignore the many occasions when it loses.
Treat each win as proof.
Explain each loss as an exception.

The belief becomes self-protecting.

Cautious Exam Use

The safest AQA approach is to prioritise the biases explicitly identified in the official mark scheme:

Control bias.
Ritual bias.
Gambler’s fallacy.
Selective recall or availability bias.
Skill bias.
Near-win bias.

Confirmation bias may be used to clarify how these beliefs are maintained, but it should not replace the required material.

Irrational Verbalisations

What Are Irrational Verbalisations?

Gamblers may express distorted thoughts aloud while gambling.

The AQA specimen mark scheme gives the example:

“The machine hates me.”

Other examples might include:

“The machine is teasing me.”
“It is saving a win for later.”
“I have found its pattern.”
“It knows I am about to leave.”
“I can feel a win coming.”
“The last loss was a warning to change numbers.”

These comments may reveal:

Personification.
Illusion of control.
Pattern perception.
Gambler’s fallacy.
Post hoc rationalisation.

Personification

Personification involves treating a machine or chance process as though it has:

Intentions.
Emotions.
Memory.
A plan.

For example:

“The machine is punishing me.”

A machine does not need to possess intentions for the gambler to interpret its behaviour socially.

This interpretation may make random outcomes feel meaningful.

Chasing Losses

What Is Chasing Losses?

Chasing losses means continuing or increasing gambling in an attempt to recover money already lost.

The person may think:

“One win will put everything right.”
“I cannot stop while I am behind.”
“The next bet will recover today’s losses.”
“Stopping now would make the losses permanent.”

Cognitive Processes in Chasing Losses

Chasing may involve:

Gambler’s fallacy.
Overestimation of winning.
Illusion of control.
Selective recall.
Underestimation of further risk.
Refusal to treat past losses as unrecoverable.

The Sunk-Cost Problem

Money already lost cannot be recovered by changing the past.

However, the gambler may believe that previous investment provides a reason to continue.

The distorted sequence becomes:

I have lost a great deal → I must continue to recover it

rather than:

Continuing creates the possibility of further loss

Applying Chasing

Harriet has lost £300. She doubles her next bet because she believes one large win will undo all her previous losses.

This may involve:

Overestimating the likelihood of winning.
Underestimating the possibility of further loss.
Believing continued gambling is necessary to correct the situation.
Increasing the financial risk.

Cognitive Biases Before, During and After Gambling

Biases can operate at different points.

Before Gambling

The person may:

Overestimate the probability of winning.
Believe they possess special skill.
Select a lucky ritual.
Predict that a win is due.
Underestimate risk.

During Gambling

The person may:

Personify the machine.
Interpret near misses as progress.
Believe their movements influence the outcome.
Reinterpret losses.
Chase previous losses.

After Gambling

The person may:

Remember wins and forget losses.
Explain wins through skill.
Explain losses through bad luck.
Construct hindsight explanations.
Minimise total financial damage.

The biases form a continuing system rather than one isolated thought.

A Cognitive Maintenance Cycle

A possible cognitive cycle is:

The gambler overestimates the chance of winning.
They place a bet.
A loss is interpreted as making a win due.
A near miss is interpreted as almost succeeding.
Another bet is placed.
An occasional win is attributed to skill or ritual.
The win becomes highly memorable.
Numerous losses are forgotten or explained away.
Confidence increases.
Gambling continues.

The cycle protects the person’s belief that future gambling is worthwhile.

Cognitive Theory and Initiation

Can Cognitive Bias Explain the First Gamble?

Some distorted beliefs may be present before the first gambling experience.

For example, the person may already believe:

They are unusually lucky.
They can predict sport accurately.
Gambling is an easy way to make money.
A personal system guarantees success.

However, many biases may develop through gambling experience.

For example:

A coincidental win may create ritual bias.
Variable rewards may support the gambler’s fallacy.
A near miss may be interpreted as progress.
Repeated gambling creates memories available for selective recall.

The official mark scheme identifies cognitive bias as generally better at explaining maintenance than initiation.

Alternative Explanations of Initiation

The first gambling experience may be better explained by:

Family modelling.
Peer influence.
Availability.
Sensation seeking.
Advertising.
Curiosity.
Financial motivation.

These factors are examined in personality and social influences on addiction.

Cognitive Theory and Maintenance

Cognitive explanations are particularly useful for understanding why gambling continues despite:

Repeated losses.
Accurate information about probability.
Financial harm.
Attempts by others to challenge the behaviour.
Lack of regular rewards.

The gambler does not process each loss as evidence that gambling should end.

Instead, a loss may be interpreted as:

A sign that a win is due.
A temporary setback.
Evidence that a method needs adjustment.
A near success.
Bad luck rather than poor judgement.

Distorted thinking therefore protects continued gambling.

Applying Cognitive Bias to Different Forms of Gambling

Slot Machines

Relevant biases may include:

Gambler’s fallacy.
Illusion of control.
Ritual bias.
Near-miss bias.
Personification.
Selective recall.

Example:

“The machine nearly paid out, and it has not paid for ages. It must be ready.”

Roulette

Relevant biases may include:

Gambler’s fallacy.
Pattern perception.
Ritual bias.
Illusion of control.
Selective recall.

Example:

“Black has appeared repeatedly, so red must be next.”

Lotteries

Relevant biases may include:

Skill bias.
Illusion of control.
Ritual bias.
Availability bias.
Overestimation of winning.

Example:

“Choosing birthdays makes my ticket more likely to win.”

Sports Betting

Relevant biases may include:

Skill bias.
Hindsight bias.
Selective recall.
Overconfidence.
Underestimation of uncertainty.

Example:

“I understand football better than other bettors, so my predictions are almost guaranteed.”

Horse Racing

Relevant biases may include:

Skill bias.
Ritual bias.
Selective recall.
Hindsight bias.
Illusion of control.

Example:

“I knew the horse would win because it looked confident before the race.”

Card Games

Relevant biases may include:

Overconfidence in skill.
Illusion of control.
Selective recall.
Hindsight bias.
Personification of chance.

Skill may genuinely influence some card-game decisions, but cognitive bias occurs when the gambler overestimates the control provided by that skill.

Worked Example

Amir gambles using a roulette application. Red has appeared on six consecutive spins. Amir says black must now occur because the game has to balance itself. He wears a particular bracelet whenever he plays and believes it improves his luck. When black finally appears, he tells his friends that the bracelet worked. He rarely mentions the money he lost before the win.

Gambler’s fallacy

Amir believes that six red outcomes make black due.

Ritual bias

He believes the bracelet influences a random outcome.

Illusion of control

He believes a personal action or object controls chance.

Confirmation bias

The black result is treated as proof that the bracelet works.

Selective recall

He remembers the win but gives little attention to previous losses.

Maintenance

The combination of biases makes continued gambling appear reasonable and successful.

Cognitive Theory Compared with Learning Theory

Cognitive theory	Learning theory
Focuses on thoughts, beliefs and interpretations	Focuses on behaviour and consequences
Explains distorted understanding of chance	Explains gambling being reinforced by wins
Gambler’s fallacy makes a win seem due	Partial reinforcement teaches persistence through losses
Illusion of control creates a belief in personal influence	Variable reinforcement makes reward unpredictable
Near misses are interpreted as progress	Actual wins positively reinforce gambling
Selective recall distorts memory	Reinforcement strengthens the response
Explains why losses may encourage gambling	Explains why occasional rewards maintain gambling
Cognitive explanation	Environmental explanation

Complementary Explanations

The explanations may work together.

For example:

A gambler receives occasional wins.
The wins positively reinforce betting.
The person remembers wins more strongly than losses.
They overestimate the chance of success.
A losing sequence produces the gambler’s fallacy.
Another occasional win appears to confirm the bias.
Gambling becomes increasingly persistent.

Learning theory explains why consequences strengthen behaviour.

Cognitive theory explains how the gambler interprets those consequences.

Cognitive Theory and Personality

Cognitive biases may be influenced by individual differences.

The AQA mark scheme identifies possible mediating factors including:

Self-efficacy.
Impulsivity.
Desire for control.

Impulsivity

An impulsive person may:

Act on a biased thought immediately.
Place another bet without checking evidence.
Give priority to possible immediate reward.
Ignore delayed financial harm.

Desire for Control

A person with a strong desire for control may find the illusion of control especially attractive.

They may prefer to believe:

“My actions influence the result.”

rather than accept that the outcome is uncertain.

Self-Efficacy

A gambler may possess high confidence in their gambling ability.

This confidence could strengthen:

Skill bias.
Overestimation of control.
Persistence after losses.

Alternatively, low self-efficacy for stopping may create the belief:

“I cannot resist the urge to gamble.”

Personality and cognition may therefore interact.

Cognitive Theory and Neurochemistry

Gambling outcomes may activate reward systems involving dopamine.

The cognitive and biological levels may interact:

A win produces reward-related brain activity.
Selective recall makes the rewarding experience highly accessible.
A near miss may create anticipation.
Cognitive expectations increase motivation to continue.
Reward and expectation strengthen one another.

Cognitive theory explains the meaning assigned to the event.

Neurochemistry explains part of how reward and motivation are processed.

Cognitive Theory and Social Influence

Social environments may transmit gambling beliefs.

Friends or family members may say:

“You have to keep going after losses.”
“That machine is lucky.”
“You are excellent at predicting games.”
“Near misses mean you are improving.”
“Our group always uses these numbers.”

The person may learn biased interpretations through:

Modelling.
Group norms.
Social reinforcement.
Repeated discussion.

This shows that cognitive biases need not develop independently of social experience.

Evaluating Cognitive Explanations

Strength: Explains Gambling Despite Repeated Losses

A major strength is that cognitive theory explains why losses do not always reduce gambling.

A loss may be interpreted as:

Evidence that a win is due.
A near success.
Bad luck.
A reason to improve the strategy.
A reason to recover previous money.

The theory therefore explains how the same objective outcome can produce different behaviour.

One person may interpret a loss as a reason to stop.

Another may interpret it as a reason to continue.

Strength: Explains Different Meanings Assigned to the Same Event

Learning theory focuses on objective consequences.

Cognitive theory recognises that the consequence must be interpreted.

For example, a near miss is objectively a loss.

However, one gambler may think:

“I lost.”

Another may think:

“I nearly won, so I should continue.”

Cognitive appraisal helps explain individual differences in response.

Strength: Covers Several Types of Biased Thinking

The explanation is flexible because it includes several processes:

Gambler’s fallacy.
Illusion of control.
Ritual bias.
Skill bias.
Selective recall.
Hindsight bias.
Near-miss bias.

Different biases may maintain different forms of gambling.

The official AQA mark scheme explicitly recognises that some biases apply better to some forms of gambling than others.

Limitation: No Single Bias Explains Every Form of Gambling

The gambler’s fallacy may be especially relevant where repeated chance outcomes are visible, such as:

Roulette.
Slot-machine play.
Repeated dice throws.

Skill bias may be more relevant to:

Sports betting.
Horse-racing predictions.
Card games.

Ritual bias may appear across several activities but may not be present in every gambler.

The cognitive explanation is therefore not one universal mechanism.

Strength: Cognitive Processes Can Be Investigated

Researchers can examine gambling-related thinking through:

Questionnaires.
Interviews.
Recorded verbalisations.
Decision-making tasks.
Recall of wins and losses.
Judgements of probability.
Responses to near misses.

These methods can identify systematic differences between:

More persistent gamblers.
Less persistent gamblers.
Different gambling situations.

Limitation: Self-Report Problems

Gamblers may not report thoughts accurately because they:

Forget what they were thinking.
Lack insight.
Feel embarrassed.
Give socially desirable answers.
Rationalise behaviour after the event.
Describe beliefs differently once they know the outcome.

A reported bias may therefore reflect:

The actual thought during gambling.
A later explanation.
Impression management.
Memory reconstruction.

Limitation: Think-Aloud Methods May Change Behaviour

Asking gamblers to verbalise every thought may:

Make them more self-conscious.
Interrupt automatic thinking.
Change the pace of gambling.
Encourage more rational reflection.
Produce demand characteristics.

The method may reveal cognitive processes while also altering them.

Limitation: Correlation Does Not Establish Causation

Research may find that persistent gamblers show more cognitive biases.

This does not prove that the biases caused addiction.

Possible relationships include:

Cognitive biases increase gambling risk.
Repeated gambling experience creates cognitive biases.
Occasional wins reinforce biased beliefs.
Personality affects both bias and addiction.
Social experience influences both.

The direction of effect is therefore uncertain.

Biases May Be a Consequence of Gambling

A person may develop the illusion of control after:

Experiencing a coincidental win.
Repeating a ritual during a successful bet.
Receiving praise for a prediction.
Observing a near miss.
Spending a long time studying one activity.

The bias may maintain addiction without having initiated it.

This supports the AQA judgement that cognitive bias may explain maintenance better than initiation.

Strength: Treatment Applications

If distorted thoughts maintain gambling, treatment can aim to change those thoughts.

Cognitive behaviour therapy may help a person:

Identify biased beliefs.
Examine evidence for and against them.
Calculate losses more accurately.
Challenge the illusion of control.
Recognise that previous losses do not make a win due.
Reclassify near misses as losses.
Develop alternative thoughts.
Plan for high-risk situations.

AQA explicitly identifies cognitive therapy aimed at changing perceptions of control as a practical implication of the explanation.

This prepares you for challenging addictive thoughts through CBT.

Treatment Effectiveness as Indirect Support

If changing cognitive bias reduces gambling, this would be consistent with cognition playing a causal or maintaining role.

However, treatment may include several components:

Coping skills.
Time management.
Relaxation.
Social support.
Behavioural alternatives.
Relapse prevention.

Improvement cannot automatically be attributed only to cognitive restructuring.

Limitation: Knowing the Odds May Not Be Enough

A gambler may understand probability accurately outside the gambling situation but still gamble when:

Emotionally aroused.
Excited.
Stressed.
Exposed to gambling cues.
Trying to recover losses.
Receiving variable reinforcement.

The person may possess accurate abstract knowledge but fail to apply it during gambling.

This suggests that irrational behaviour is not always caused by ignorance.

Emotion, reward and impulse control may override knowledge.

Limitation: Cognitive Biases Also Occur in Non-Addicted Gamblers

Occasional gamblers may also:

Use lucky numbers.
Believe in short-term patterns.
Remember wins.
Feel in control.
Interpret near misses positively.

The presence of a cognitive bias does not necessarily demonstrate addiction.

The explanation must account for:

Frequency.
Strength.
Persistence.
Interaction with reinforcement.
Financial and social consequences.
Ability to stop.

Limitation: Individual Differences

The AQA mark scheme identifies individual characteristics such as impulsivity, self-efficacy and desire for control as mediating influences.

This means the same bias may affect people differently.

For example:

An impulsive gambler may act immediately on the belief that a win is due.
A less impulsive person may question the belief and stop.
A person high in desire for control may strongly prefer rituals.
Another person may accept that the outcome is random.

Cognition cannot be separated completely from personality.

Cognitive Reductionism

The explanation may be criticised as cognitively reductionist because it reduces gambling addiction to:

Irrational beliefs.
Probability errors.
Memory bias.
Perceived control.

This focus has advantages:

Specific processes can be identified.
Predictions can be tested.
Treatment can target the thoughts.

However, it may overlook:

Reinforcement schedules.
Genetic vulnerability.
Brain reward systems.
Personality.
Stress.
Social influence.
Availability.
Financial circumstances.

A cognitive bias may explain how the person interprets gambling without explaining every cause of the addiction.

Cognitive Determinism

The explanation may appear deterministic if distorted thinking is presented as automatically producing gambling.

However, people can:

Reflect on their beliefs.
Learn probability principles.
Use coping strategies.
Restrict access.
Challenge irrational thoughts.
Choose not to act on an urge.

Cognitive therapy itself assumes that thinking can change.

The approach therefore allows more conscious control than a completely deterministic biological explanation.

Better Explanation of Maintenance Than Initiation

Cognitive theory effectively explains:

Persistent gambling.
Chasing losses.
Larger bets.
Interpreting near misses.
Returning after a loss.
Remembering wins selectively.

It may be less effective at explaining:

First exposure.
Availability.
Family modelling.
Peer pressure.
The initial financial reward.
Biological reward sensitivity.

This limitation is directly identified in the AQA mark scheme.

Comparison with Learning Theory

Learning theory may explain how a bias develops or is maintained.

For example:

A gambler performs a ritual.
A coincidental win follows.
The ritual-win association is reinforced.
The gambler develops the belief that the ritual caused the win.
The ritual and gambling are repeated.

The cognitive and learning explanations are therefore complementary.

Comparison with Genetic Vulnerability

Genetic vulnerability may affect:

Impulsivity.
Reward sensitivity.
Desire for stimulation.
Behavioural control.

These characteristics may influence whether a cognitive bias leads to action.

Genetic theory explains inherited vulnerability.

Cognitive theory explains the person’s interpretation of gambling events.

Comparison with Social Influence

Family and peers may teach:

Gambling rules.
Superstitions.
Attitudes towards luck.
Confidence in betting skill.
Ways to interpret wins and losses.

Social influence may therefore shape the content of gambling cognitions.

Interactionist Explanation

A more complete explanation might involve:

Genetic vulnerability contributes to impulsivity.
Friends introduce the person to gambling.
An early win positively reinforces betting.
Variable reinforcement creates persistence.
The gambler selectively remembers the win.
Losing produces the gambler’s fallacy.
Near misses are interpreted as progress.
Cognitive bias encourages further gambling.
Biological reward and social approval strengthen the cycle.

This explanation combines:

Biological vulnerability.
Personality.
Social exposure.
Learning.
Cognition.

Practical Implications

Cognitive explanations suggest that prevention should address distorted beliefs before serious harm develops.

Education might challenge claims such as:

“A win is due after several losses.”
“Lucky rituals alter random outcomes.”
“A near miss means success is close.”
“Choosing personally meaningful numbers improves probability.”
“Remembered wins show overall profitability.”
“Expert knowledge removes uncertainty.”

Gambling Records

A person might be encouraged to record:

Every bet.
Every stake.
Every win.
Every loss.
Total time spent.
Overall financial outcome.

This could reduce selective recall by replacing memory with a complete record.

Reclassifying Near Misses

The gambler can be encouraged to classify outcomes accurately:

Win.
Loss.

A near miss remains a loss.

This may weaken the belief that the person is making progress.

Challenging Illusion of Control

The person may examine whether:

Changing rituals alters outcomes.
Personal number selection improves probability.
Pressing a button differently affects the result.
The supposed strategy succeeds consistently.

The aim is to compare the belief with objective evidence.

Overall Evaluation

Cognitive theory explains gambling addiction through irrational thinking and biased interpretations of chance. Gamblers may overestimate the chance of winning, underestimate the risk of losing and believe that random outcomes can be controlled.

Important cognitive biases include the gambler’s fallacy, illusion of control, ritual bias, skill bias, selective recall, hindsight bias and near-miss bias. These biases can turn losses into reasons to continue, attribute random wins to personal ability and create an inaccurate memory of overall success.

The explanation is particularly valuable because it accounts for how different gamblers interpret the same objective event. It also has clear treatment applications because cognitive behaviour therapy can identify and challenge distorted beliefs.

However, cognitive biases may be consequences rather than original causes of gambling. They are often investigated using self-report or artificial tasks, and similar biases appear among people without addiction. Different biases also apply to different gambling activities.

The most balanced conclusion is that cognitive theory provides a strong explanation of the maintenance of gambling addiction. It becomes more complete when combined with partial reinforcement, personality, social influence and biological reward processes.

Hints from the Examiner Reports 💡

No lesson-specific examiner guidance was identified in the provided examiner reports.

The official question papers and mark schemes nevertheless give clear guidance about what AQA rewards.

Learn Several Clearly Different Biases

The November 2020 examination asked students to discuss cognitive bias as an explanation of gambling addiction. The mark scheme accepted:

Control bias.
Ritual bias.
Gambler’s fallacy.
Selective recall or availability bias.
Skill bias.
Near-win bias.

Do not describe every example as simply “irrational thinking”.

Explain How the Bias Increases Gambling

Weak answer:

The gambler has an illusion of control.

Improved answer:

The gambler believes their timing or choice can influence a chance outcome. This increases confidence in future success and encourages them to place further bets.

Use:

Bias → distorted judgement → gambling decision → continued behaviour

Distinguish the Gambler’s Fallacy from Variable Reinforcement

Variable reinforcement means wins occur unpredictably.
The gambler’s fallacy is the belief that previous losses make a future win more likely.

Do not say that a variable-ratio schedule objectively makes a win due.

Identify the Exact Evidence in a Scenario

Scenario statement	Likely bias
“I have lost six times, so I must win next”	Gambler’s fallacy
“My lucky bracelet causes wins”	Ritual bias
“I control the result by pressing at the right time”	Illusion of control
“I am better at predicting winners than everyone else”	Skill bias
“I can remember lots of wins but few losses”	Selective recall
“I nearly won, so success is getting closer”	Near-miss bias

Do Not Treat a Near Miss as a Reinforced Win

A near miss is objectively a loss.

Cognitive theory explains why the gambler interprets it as encouraging.

Learning theory explains reinforcement by actual rewarding consequences.

Explain Selective Recall Fully

Do not write only:

The gambler remembers wins.

Add:

Because wins are more available in memory than losses, the gambler overestimates how often gambling is successful and continues betting.

Apply Skill Bias Carefully

Some gambling activities contain genuine elements of skill.

The bias occurs when the gambler:

Overestimates that skill.
Treats skill as guaranteeing uncertain outcomes.
Ignores chance and contradictory evidence.

Use Specialist Terminology

Strong terms include:

Cognitive bias.
Illusion of control.
Gambler’s fallacy.
Selective recall.
Availability bias.
Skill bias.
Near-miss bias.
Hindsight bias.
Irrational verbalisation.

Evaluate Different Gambling Activities

AQA specifically recognises that some biases explain some gambling activities better than others.

For example:

Gambler’s fallacy is highly relevant to roulette and repeated slot-machine outcomes.
Skill bias may be more relevant to sport, horse racing or card games.
Near-miss bias is especially relevant where closeness is made visible.

Discuss Maintenance and Initiation

The mark scheme identifies cognitive bias as more effective at explaining maintenance than initiation.

A developed point is:

Biases explain why the gambler continues after wins and losses, but social influence, availability or sensation seeking may better explain why gambling began.

Link Evaluation to Treatment

AQA accepts the practical implication that cognitive therapy may change distorted perceptions of control.

Explain:

If irrational beliefs maintain gambling, cognitive restructuring should reduce the motivation to continue by challenging those beliefs.

Compare with Learning Theory

A strong comparison is:

Learning theory explains how occasional wins reinforce gambling. Cognitive theory explains why losses and near misses can also encourage gambling through distorted interpretation.

Develop Individual Differences

Do not write only:

Personality matters.

Explain:

An impulsive person may act immediately on the belief that a win is due, whereas someone with stronger self-control may recognise the bias and stop.

Explain that inherited reward sensitivity or impulsivity may determine which gamblers act on biased thoughts.

Mistake 15

Mistake: Treating learning and cognitive explanations as mutually exclusive.

Why this is unrealistic:

Reinforcement may create experiences that cognitive biases later interpret.

How to improve:

Use an interactionist comparison.

Answers and Mark Scheme

Question 1

Award one mark for each of the following:

A systematic error or distortion in thinking, memory or judgement.
The distortion affects the gambler’s understanding of chance, control, wins or losses and may encourage continued gambling.

Maximum: 2 marks

Question 2

Award one mark for each linked point, up to three marks:

The gambler believes a run of one outcome makes the opposite outcome more likely.
For example, repeated losses are believed to make a win due.
Earlier independent outcomes do not necessarily alter the next outcome.
The faulty belief encourages another bet.

Question 3

Award up to two marks for each accurately explained bias.

Possible answer:

Illusion of control is the belief that personal choices or actions can influence a substantially chance-based outcome, such as believing that pressing a button at the right moment creates a win. Selective recall concerns memory rather than control. The gambler remembers successful bets more readily than losses, causing them to overestimate how often gambling is successful.

Question 4

Award one mark for each relevant applied point:

The statement demonstrates the gambler’s fallacy.
The gambler incorrectly believes the seven losses alter the probability of the next spin.
They expect chance to correct or balance the sequence.
This distorted expectation encourages another bet.
The machine is also being personified as though it deliberately decides when to pay.

Maximum: 3 marks

Question 5

Award up to two marks for each bias.

Illusion of control or skill bias

Lena believes choosing the numbers increases her chance of success.
She overestimates the control provided by personal choice.

Ritual bias

She believes the necklace influences the lottery outcome.
A lucky object is being treated as causally effective.

Selective recall or availability bias

She readily recalls two wins.
She cannot remember the total losses.
Winning memories may lead her to overestimate her success.

Other creditworthy application includes confirmation bias where previous wins are used to validate the necklace or number choices.

Question 6

Award one mark for each relevant linked point, up to four marks:

The displayed result is objectively a loss.
The gambler interprets it as a near win.
This demonstrates near-miss or near-win bias.
The gambler believes closeness means future success is more likely.
Saying the machine is “getting ready” personifies it.
The distorted interpretation motivates another bet.
The near miss therefore maintains gambling without providing a financial reward.

Question 7

The frequent gamblers estimated 34 wins but recorded 17.

Award up to two marks for the calculation:

Overestimate=34−17=17Percentage overestimate=1717×100=100%

Frequent gamblers overestimated their recorded wins by 100%.

Award up to two marks for cognitive interpretation:

Frequent gamblers may display selective recall or availability bias.
Memorable wins may be easier to retrieve than losses.
This could cause them to overestimate their success.
The greater difference among frequent gamblers is consistent with stronger cognitive bias.

Award up to two marks for a limitation:

Estimates may be affected by social desirability.
Participants may not understand the question.
Recorded outcomes may be incomplete.
The study is correlational and cannot show that bias caused frequent gambling.
Frequent gambling may itself have produced the memory bias.
The two groups may differ in personality, gambling type or experience.

Question 8

Award one mark for each linked point, up to three marks:

Gambling must normally begin before the person experiences repeated wins, losses or near misses.
Social influence, opportunity or sensation seeking may therefore explain initial participation.
Cognitive biases can then interpret gambling experiences.
The gambler’s fallacy, selective recall and near-miss bias encourage continued betting.
Cognitive theory is therefore particularly useful for explaining maintenance.

Question 9

Award up to three marks for one developed strength and up to three marks for one developed limitation.

Possible strength:

Cognitive theory explains why gamblers may continue after objective losses. A near miss can be interpreted as progress, while the gambler’s fallacy makes a losing sequence seem to increase the chance of winning. The theory therefore explains why the same loss leads one person to stop but another person to continue.

Possible limitation:

Research linking cognitive bias with gambling is often correlational. Persistent gambling may create biased beliefs through repeated experience, rather than the beliefs causing the addiction. A coincidental win following a ritual could produce the illusion of control, so direction of effect remains uncertain.

Other creditworthy evaluation includes:

Different biases applying to different gambling activities.
Self-report or think-aloud limitations.
Treatment implications.
Similar biases among non-addicted gamblers.
Better explanation of maintenance than initiation.
Cognitive reductionism.
Individual differences.
Comparison with learning theory.

Thirteen to sixteen marks: Knowledge is accurate and generally detailed. Several cognitive biases are clearly distinguished and linked to persistent gambling. Discussion is thorough and focused, considering causality, methods, individual differences, treatment implications and alternative explanations. Specialist terminology is used precisely.

Nine to twelve marks: Knowledge is mostly accurate and discussion is generally effective. Cognitive bias is explained using relevant examples, although some evaluation points may lack depth or balance.

Five to eight marks: Some relevant knowledge is present, but the response is mainly descriptive. Biases may be listed without explaining how they maintain gambling, or evaluation may be generic.

One to four marks: Knowledge is very limited or confused. The answer may treat a win as objectively due after losses, confuse cognitive bias with reinforcement or provide little relevant evaluation.
