Cognitive Theory of Gambling Addiction (AQA A-Level Psychology): Revision Notes
Cognitive Theory of Gambling Addiction
The cognitive approach suggests that gambling addiction develops through distorted thinking patterns and irrational beliefs about gambling outcomes. This theory proposes that individuals with gambling problems differ from non-gamblers in how they perceive, interpret and think about gambling situations.
The cognitive theory focuses on the mental processes and thought patterns that contribute to gambling addiction, rather than just examining external behaviours or biological factors.
What is cognitive bias?
Cognitive bias refers to systematic distortions in attention, memory and thinking processes. These biases emerge from how we rapidly process information about our environment. People tend to recall memories that support their existing beliefs whilst ignoring contradictory information, which can result in irrational judgements and poor decision-making.
Cognitive biases are not random errors in thinking - they are systematic patterns that consistently lead people away from rational decision-making, making them particularly dangerous in gambling situations.
Expectancy theory
Expectancies form the foundation of the cognitive explanation for gambling addiction. Gamblers develop expectations about the future benefits and costs of their gambling behaviour. When they believe the benefits will outweigh the costs, addiction becomes more probable. This resembles a conscious decision-making process, but it is not entirely rational because memory and attention processes do not function in a completely logical manner.
Cognitive biases in gambling addiction
Research by Debra Rickwood and colleagues (2010) identified four main categories of cognitive biases that characterise gambling addiction:
Skill and judgement biases
Gambling addicts experience an illusion of control, leading them to overestimate their ability to influence random events. For example, they may believe they possess special skills in selecting lottery numbers or can somehow control slot machine outcomes.
Personal traits and ritual behaviours
Addicted gamblers often believe they have a greater probability of winning due to personal luck or engaging in superstitious behaviours. This might involve touching a particular item of clothing before placing a bet or following specific rituals they believe will increase their chances of success.
Selective recall
Gamblers can vividly remember details of their wins but tend to forget, ignore or minimise their losses. Losses are frequently interpreted as unexplainable mysteries rather than expected outcomes of chance-based activities.
Faulty perceptions
Addicted gamblers hold distorted views about how chance operates, exemplified by the gambler's fallacy. This is the mistaken belief that a losing streak cannot continue indefinitely and must soon end with a win, despite each gambling event being independent of previous outcomes.
Key study: Griffiths (1994)
Worked Example: Investigating Cognitive Biases in Gamblers
Aim: To investigate cognitive biases in gamblers by comparing regular and occasional slot machine players.
Participants: Regular slot machine gamblers and people who used the machines only occasionally.
Procedure: Griffiths employed the 'thinking aloud' method (a form of introspection) to examine cognitive processes during gambling. Participants verbalised their thoughts while playing slot machines. A content analysis classified these utterances as either rational ('I won ten pence') or irrational ('This machine likes me'). A semi-structured interview gathered participants' opinions about skill requirements for winning. Objective behavioural measures were recorded, including number of plays per session and total winnings.
Findings: No differences existed between regular and occasional gamblers in objective behavioural measures - regulars did not win more money. However, regular gamblers made almost six times as many irrational verbalisations compared to occasionals (14% versus 2.5%). They showed particular tendency towards illusions of control ('I'm going to bluff this machine'). Regular gamblers overestimated both the skill required to win on slot machines and their own gambling abilities compared to occasional gamblers.
Evaluation - Strengths:
- Provided clear evidence of cognitive distortions in regular gamblers
- Used multiple methods (thinking aloud, interviews, behavioural measures) for comprehensive data collection
- Demonstrated practical differences between regular and occasional gamblers
Evaluation - Weaknesses:
- Relied on self-report methods which may not reflect genuine beliefs
- Small sample size limits generalisability
- Thinking aloud method may alter natural gambling behaviour
Self-efficacy
Self-efficacy describes our expectations about our ability to behave in ways that achieve desired outcomes. It helps explain why some individuals relapse into gambling after periods of abstinence. When someone lacks confidence in their ability to permanently give up gambling, this creates a self-fulfilling prophecy. The individual behaves in ways that confirm this expectation (continuing to gamble), which then reinforces their belief that they cannot quit permanently.
Self-efficacy beliefs become particularly powerful because they influence both the likelihood of attempting to quit gambling and the persistence shown when facing setbacks or temptations.

Michalczuk et al. (2011)
Supporting Evidence for Cognitive Distortions
This study compared 30 addicted gamblers attending the National Problem Gambling Clinic in the UK with 30 non-gambling control participants. The addicted gamblers demonstrated higher levels of all types of gambling-related cognitive distortions, including illusions of control. They were also more impulsive, showing preferences for immediate rewards even when larger rewards were available later. These findings support the view that cognitive factors play a substantial role in gambling addiction, with addicted gamblers showing powerful tendencies towards distorted thinking during play.
McCusker and Gettings (1997) - Automatic cognitive bias
Evidence for Automatic Processing
Using a modified Stroop procedure, participants had to identify ink colours of words as quickly as possible whilst ignoring word meanings. Gamblers took longer to complete this task when words were gambling-related compared to controls. They could not prevent gambling-related word meanings from automatically interfering with the intended task. This provides evidence that gamblers possess an automatic cognitive bias towards gambling-related information that does not exist in non-gamblers.
Evaluation
Research support
Multiple studies consistently demonstrate that addicted gamblers show higher levels of cognitive distortions compared to non-gamblers. The evidence supports the view that cognitive biases contribute to both the initiation and maintenance of gambling addiction.
Explains automatic behaviour
Research reveals that frequent gamblers can place bets automatically, as predicted by cognitive theory. The Stroop study evidence shows gamblers have automatic cognitive biases towards gambling-related information that operate without conscious awareness, supporting the theory that many cognitive biases influence addiction unconsciously.
Clinical Applications
The suggestion that addicted gamblers think systematically differently from non-gamblers has valuable implications for treatment and prevention. Cognitive behaviour therapy (CBT) directly targets distorted thinking patterns such as the gambler's fallacy or the excessive importance gamblers attribute to near-misses. Clark (2010) suggests that cognitive distortions may have underlying causes in brain neurochemistry, stimulating research into both biological and psychological treatments.
Individual differences
Several individual differences may determine how gamblers perceive and interpret their gambling experiences. Burger and Smith (1985) investigated control motivation as a personality factor. People with high control motivation are more likely to believe they can influence chance-determined situations, potentially attracting them to gambling types where they wrongly believe their 'skill' matters, such as lottery number selection. Such individual differences mean cognitive biases alone cannot fully explain gambling addiction.
Methodological Limitations
Many research studies investigating cognitive distortions in gambling rely on self-report methods such as the thinking aloud technique. Dickerson and O'Connor (2006) highlight that what people say during gambling situations may not accurately represent their genuine thoughts. Casual or spontaneous remarks during slot machine sessions might not reflect the addict's deeply-held beliefs about chance and skill in their behaviour. This potentially undermines the validity of research supporting cognitive theory, as researchers may obtain misleading pictures of gamblers' actual thought processes.
Key Points to Remember:
- Cognitive theory explains gambling addiction through distorted thinking patterns and irrational beliefs about gambling outcomes
- Four main cognitive biases include illusions of control, superstitious beliefs, selective recall, and faulty perceptions like the gambler's fallacy
- Griffiths (1994) found regular gamblers made six times more irrational statements than occasional gamblers whilst playing slot machines
- Self-efficacy explains relapse through self-fulfilling prophecies about inability to quit permanently
- The theory has strong research support and leads to effective CBT treatments, but faces challenges from individual differences and methodological limitations in self-report studies
