- Boredom Avoidance
- pathological gambler needs this intense stimulation and excitement.
- poor tolerance to boredom leads to repetitive gamblin behaviour. higher boredness proness.
- Explaining Individual Differences
- genetic explanations explain why some people develop pathological gambling and others do not. genetic predisposition creates a vulnerability; more resistant to treatment.
- Ignores Environmental and situational factors
- ignores the importance of external factors; accessiblity, incentives, provision of alcohol.
- product of biological factors and interaction between both environmental and genetic.
- Explanatory Limitations of the Biological Approach
- cannot exlplain why some types of gambling are more addictive than others
- those hooked on video gambling became compulsive gamblers in a year opposed to betting on horses or sports which…
