With Reference To Relevant Research Studies, To What Extent Does Genetic Inheritance Influence Behavior? Flashcards
What is “genetic”
Genes are DNA that have been transferred from parent to offspring.
Types of studies
Twin studies
Adoption studies
Family studies
Outline intelligence studies
Study 1
Bouchard and Mcgue (1982)
What is meta analysis
Meta-analysis is the use of other studies quantitive data.
Positive for meta analysis
Using meta analysis it shows data from different perspectives. Meta analysis is also good because of the amount of data that is collected.
Negative of meta analysis
There is more risk for researcher bias
“Potential researcher bias”
Aim of Bouchard an Mcgue (1982)
To find if there was a correlation between genes and intelligence
Method of Bouchard and Mcgue (1981)
Conducted a meta-analysis of 111 Studies of siblings
Investigated the IQ correlations between the siblings
Results Bouchard and McGue (1981)
It was found is that there is a correlation between kinship and are you correlation
Good post through the siblings were, in more similar their IQ was
Critical thinking Duchardin McGue (1981)
The use of meta-analysis can lead to researcher bias
Study 2
Scarr and weinberg and horn et.al. (1977)
Aim for scarr and weinberg and horn et.al.
To find a correlation between adoptive parents and biological parents when having the same up bringing.
Results of the scarr, wienberg and horn et.al.
Found no significant differences in correlation of parent child IQs between natural and adopted children
Conclusion scarr, wienberg and horn et.al.
In conclusion genetics has little impact on IQ
It is mostly impacted by environment
Study 3
Wahlsten (1997)
