Q

What evidence is there for the genetic explanation of addiction?

Study These Flashcards
A
  • Twin studies (Carmelli et al. (1992))
  • Adoption studies (Goodwin et al. (1973))
  • DDR2 gene (dopamine receptor) linked to addiction
24
Q

What are the strengths of the genetic explanation of addiction?

Study These Flashcards
A
  • Evidence: twin and adoption studies
  • Explains why some people are more prone to addiction than others
25
What are the weaknesses of the genetic explanation of addiction?
- Reductionist: doesn't take social factors into account) - No single gene found (DDR2 also linked to autism)
26
What are the three theories for the learning explanation of addiction?
- Classical conditioning - Operant conditioning - Social learning theory
27
What is classical conditioning?
Learning through association (links substance with positive feelings)
28
What is operant conditioning?
Reinforcement of behaviours leading to positive outcomes (behaviour --> positive outcome --> behaviour repeated)
29
What is social learning theory?
Behaviour learned from role models, more inclined to substances you've been exposed to
30
What are the strengths of the learning explanation of addiction?
- Treating addiction: assumes a behaviour can be unlearned - Explains why people relapse
31
What are the weaknesses of the learning explanation of addiction?
- Ignores biological factors - Doesn't explain why some are more prone to addiction than others
32
What are the two stages of CBT for addiction?
- Functional analysis (understand sources/triggers) - Skills training (how to cope with cravings, assertiveness training, improving motivation)
33
What are the strengths of CBT as a treatment of addiction?
- Builds up skills, patients has control - Evidence: Young (2007) study
34
What are the weaknesses of CBT as a treatment of addiction?
- Relies on patient being motivated (symptoms of finding stopping hard and ignoring evidence) - Skills gained don't guarantee those skills will be used/behaviour will stop
35
What are the uses of drug therapy as a treatment for addiction?
- Reduces withdrawal symptoms - Reduces cravings - Can help severe behavioural addictions
36
What are the strengths of drug therapy as a treatment of addiction?
- Evidence: Suck Won Kim et al. (2001), gambling addictions helped more with drug than placebo - Helps patients access CBT
37
What are the weaknesses of drug therapy as a treatment of addiction?
- Mixed evidence: Krysatl et al. (2001), drug and placebo relapse rate no difference after 6 months for alcoholics - Patients may become addicted to withdrawal/craving drugs
38
What were the results of the Caspi et al. (2003) study?
- Patients more likely to become depressed after stressful life event if they have at least one copy of the short 5-HTT gene - Depression caused by interaction between nature and nurture
39
What were the strengths of the Caspi et al. (2003) study?
- Large sample size - Useful for doctors (different possible causes)What were the results of the Caspi et al. (2003) study?
40
What were the weaknesses of the Caspi et al. (2003) study?
- Short gene may make people more prone to stressful situations instead - Questionnaire self- report data, may be inaccurate
41
What were the results of the Young (2007) study?
Online CBT an effective treatment for internet addicts. Symptoms improved after 12 weeks, still better than before therapy after 6 months.
42
What were the strengths of the Young (2007) study?
- Shows online CBT can be effective - Information gathering consistent and standardised
43
What were the weaknesses of the Young (2007) study?
- Self-report data, may be unreliable - Different types on internet addictions not distinguished from each other
44
What is the nature side of the nature vs nurture debate?
Behaviour is influenced by biological factors (genes)
45
What is the nurture side of the nature vs nurture debate?
Behaviour is influenced by environmental factors (experiences, role models)
46
What are the strengths of the nature side of the nature vs nurture debate?
- Caspi et al. (2003), depression linked to short 5-HTT gene - Explains why some develop depression/addiction and other don't
47
What are the strengths of the nurture side of the nature vs nurture debate?
- Suggests that since problems are learned, they can also be unlearned (basis for treatment) - CBT works for both depression and addiction, suggesting they're caused by nurture and not nature
48
What suggests depression/addiction are caused by both nature and nurture?
- Caspi et al. (2001), combination of stressful life event and short 5-HTT gene - Gene makes people prone, experience triggers symptoms
