Thomas chess and birch method?
They studied 133 children from early infancy to adulthood(longitudinal)they observed the children and asked their parents about their child's routine and response to change

Thomas chess and birch results?
3 types 'easy' 'difficult' 'slow to warm up' easy=flexible and regular difficult=cried a lot and were demanding slow to warm up=didn't respond well to change but once adapted they were fine

Thomas chess and birch conclusion?
Temperament is innate as the ways of responding to the environment remained the same throughout life

Thomas chess and birch evaluation?
Longitudinal study-someone drops out the results will be effected parents being interviewed=social desirability 133=A lot of ppts makes the results more reliable WOrking class=cannot be generalised

Buss and plomin aim?
To test the idea that temperament is innate
6 of 16
Buss and plomin method?
The studied 228 monozygotic twins and 172 dizygotic twins. They rated the temperament of the 5 year olds by 3 aspects how emotional they were how active they were and how sociable they were. The results were then compared
7 of 16
Buss and plomin results?
There was a closer correlation between the monozygotic twins compared to the dizygotic
8 of 16
Buss and plomin conclusion?
Temperament has a genetic basis
9 of 16
Buss and plomin evaluation?
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 aim?
To see if temperament is due to biological diffrences
11 of 16
Kagan and snidman method?
They studied 4 month old babies. They were placed in a situation where the caregiver of the baby was in the baby's sight for one minute the caregiver slowly moved away whilst the researcher was showing the baby some toys for 3 minutes
12 of 16
Kagan and snidman results?
20% of the babies showed distress by either crying or moving vigorously these babies were classed as high reactive and 49%
13 of 16
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
