Cannot be generalised to individual humans as it was performed on just twins, monozygotic twins are treated in a similar way so it could be due to this instead of their temperaments

Kagan and snidman results pt2?
11 years later the ppts still seemed to fall into these groups
14 of 16
Kagan and snidman conclusion?
The differences between the groups was due to inherited differences to the way the brains responds
15 of 16
Kagan and snidman evaluation?
Easy to generalise as the was a large number of ppts. Low ecological validity as its a lab experiment. Good variable control. Behaviour was obvserved so behaviour may have been missed and this would impact the results
