Addiction Studies Flashcards
Risk Factors-Genetics-Pianezza- Results
He found out that some people lack a fully functioning enzyme which is mainly responsible for metabolising nicotine. Because expression of this enzyme is down to genetics, those with this enzyme are at a greater genetic risk of nicotine reduction
Risk Factors-Genetics-Kendler- Method
He used data from the National Swedish Adoption Study, and looked at adult who had been adopted as children, from families where at least one parent had an addiction
Risk Factors-Genetics-Kendler-Results
He found out that these people had a significantly greater risk of developing an addiction themselves, when compared to those who did not have addicted parents
Neurochemistry Explanation for Nicotine Addiction-McEvoy-Method
He studied smoking behaviours in schizophrenics. The drug Haloperidol is a dopamine antagonist which is use in the treatment of Schizophrenia.
Neurochemistry Explanation for Nicotine Addiction-McEvoy-Results
Haloperidol treatment increased smoking in this sample of participants, as they used the drug as a form of self medication, an attempt to achieve the nicotine “hit” by increasing dopamine release
Learning Explanation for Nicotine Addiction-Levin-Method
Rats were trained to self administer intravenous doses of a nicotine infusion by licking one of two waterspouts
Learning Explanation for Nicotine Addiction-Levin-Results
This behaviour increased in frequency with every session, up to 100 licks per infusion
Learning Explanation for Nicotine Addiction-Carter and Tiffany-Method
They conducted a meta-analysis of studies into the effects of cues. They included 41 studies that investigated a range if substance addictions, These studies presented dependent and non dependent smokers (and non smokers) with images of smoking related cues. They measured the participants desire or craving , along with physiological indicators of arousal
Learning Explanation for Nicotine Addiction-Carter and Tiffany-Results
They found out that dependent smokers reacted strongly to the cues. These findings were consistent across all the studies used
Support for Learning Explanation for Gambling-Dickerson-Method
He observed the behaviour of gamblers in real life gambling environments, 2 betting offices
Support for Learning Explanation for Gambling-Dickerson-Results
He found out that gamblers who placed more bets in horse races were consistently more likely than low frequency gamblers to place their bets in the last two minutes before the start of the race. Low frequency gamblers who waited until this point places their bets on the next race
Research into Cognitive Biases-Griffiths-Method
He used the “thinking out loud” method to see if there were any differences in the cognitive processes of regular slot machine gamblers compared with those who used them occasionally. The participants had to verbalize their thoughts as they played on the machine. A content analysis was used to classify these thoughts into rational and irrational. A semi structured interview method was also used to seek participants views on the degree of skill required to win on slot machines. Participants were also observed
Research into Cognitive Biases-Griffiths-Results
He found out there were no difference between regular and occasional gamblers in behavioural measures. For example, regulars did not win more more, but they did make almost six times more irrational verbalisations than the occasionals. Regular gamblers were also prone to an illusion of control, and overestimated the amount of skill required to win. Finally, they considered themselves very skilful at winning at slot machines
Support for Cognitive theory of Gambling Addictions-Michalczuk-Method
They studied 30 addicted gamblers attending the national problem gambling clinic, and compared them with 30 non gambling control patients
Support for Cognitive theory of Gambling Addictions-Michalczuk-Results
The addicted gamblers showed significantly higher levels of gambling related cognitive distortions of all types. They were also more impulsive and were more likely to prefer immediately rewards even when there were smaller than the reward they could gain if they waited
