1. Hans Eysenck he had been influential in personality because his work has been the most
cited work in all of psychology and very comprehensive. He was a clinician in Moseley hospital
in the UK. He found that no treatment is no difference than psychoanalytical therapy. Like many
of the traits theorist he worked in constructing very clear measure of his theoretical concepts.
Great importance in the measurement techniques. There is a lot of experimental support for his
Background he was born and raised by a very theatrical family. He was not interested
in psychology, he like chemistry. He left Germany because in the 1939s in order for one
to be a scholar you had to join the Nazi party. So left and heading to the UK and because
everything was full he had to join psychology. At the University of London there
psychologists such as Spearmen, Pearson, JBS Haldane, while he was there. He got great
training in British Empicism.
o Experimental Psychology/what do they do if things are done properly then you
can get a causal relationship. He notices that there was a different orientation in
psychology at the time. In experimental psychology there is treatment variance
(they want a narrow distribution/ they find variability annoying).
o Correlational psychologists also ask important questions but there isn’t any casual
explanation. What the experimental psychologists finds garbage the correlational
psychologists finds it to be interesting. They go into the natural world and look at
how variables react to one another in the real world.
o Roger ShephardHe gave us the mental rotation test. Does the amount of time
that takes to solve this problem one of these of problem relates to 3 dimensional
problems. He doesn’t just suggest we.
o Eysenck gave us a recipe he said three thing need to psychology must identify
the major dimensions, we must devise a way of measuring those dimensions, we
must link up those measurement techniques with laboratory experimentation.
Only when we do this can we fins a sound theory of personality
Definition of personality “Personality is a more or less stable and enduring
organization of a person’s character, temperament, intellect and physique, which
determines his unique adjustment to the environment. He said all of these a relatively
2. Dimensions of Personality Eysenck used factor analysis. Factor analysis is like a three
dimensional, it allows you to reduce a very large stats to a few factor. Shows you how one
response relates to other response by an individual. He gave us model that have two dimension
the social and neurotic. He later developed a third dimension, the psychotic. A hierarchy
