Unit One; Making sense of other people



Personality- Thoughts, feelings and behavior that makes an individual unique.

Temperament-  Genetic component of personality.

Temperament study, Thomas, Chess and Birch (1977)

Aim- Discover whether ways of responding to the environment remain stable throughout life.

Method- 133 children's behavior were observed and parents were questioned on their child's behavior to change.

Results- The children fell into three types;

1) Easy children, happy, flexible and regular.

2) Difficult children, demanding, inflexible and cries alot.

3) Slow to warm up, did not respond well to change or new experience.

Conclusion-These ways of responding to the environment stayed with the children as they developed, showing temperament is innate.


  • Children evaluated were from middle class family's in New York, this means results cant be generalized.
  • The parents may be bias in answers in the interview.

Evaluation of Eysenck's type theory.

Original research used a limited sample to test his ideas. This is because it was only carried out on servicemen. Since this time however, his findings have been supported by further research carried out by thousands of different people.

He used the questioners to test personality, the answers could only have been based on how the participant was feeling at the time of the experiment.

He believed that personality is genetic, but this does not consider personality change from result of experience.

Eysenck's scale to measure personality types.

Personality inventory (EPI)- The scale is used to measure extroversion-introversion and neutrocism-stability. It is made up of a series of questions, answers given can be used to identify an individuals personality.
