- With reference to relevant research studies, to what extent does genetic inheritance influence behaviour?
- 1. Introduction
- To an extent...
- Briefly outline what genetic inheritance is
- Link to BLoA?
- 2. Intelligence is 70% genetic
- Bouchard and McGue (1981)
- Meta-analysis
- Reviewed 111 studies on IQ correlations in siblings
- Found that closer the kinship-higher the correlation
- Minnesota Twin Study
- Bouchard et al (1990)
- Comparison between MZAs (Identical twins raised together) and MZTs (Identical twins raised apart)
- Cross Cultural
- Conducted over 11 years
- Each twin completed 50 hrs of testing
- Bouchard and McGue (1981)
- 3. Behaviour
- Adoption Studies
- Allows direct comparison of genetic and environmental influences on behaviour
- Correlation exhibited between behaviour and genetics
- Adoption Studies
- 4. However, there are arguments against this for example...
- 5. Intelligence
- Scarr and Weinberg (1977)
- Birth and adoptive children raised together
- Results showed no sig difference in IQ
- 6.Behaviour
- Abnormal behaviour
- Depression
- Diathesis-stress model
- Only 'genetic vunerabilty'
- no single cause-and-effect relationship between genes and behaviour
- Abnormal behaviour
- 7. Conclusion
- There is still ambiguity as to whether genetics have a direct effect on behaviour
- 1. Introduction
