All behaviors are learnt from our environment. Focus on observable behavior behavior that can be seen. Animals and humans learn in the same ways so behaviorists carry out experiments on animals and extrapolate the results to humans. Psychology should be scientific and objective therefore behaviorists use mainly laboratory experiments to achieve this.
Northwestern University To explain individual differences in personality or temperament, Eysenck proposed the PEN model and Gray attempted to reformulate Eysenck's theory.
This paper summarizes and evaluates the PEN model. Special attention is given to the contribution of the PEN model to an experimental approach to the study of personality. In the PEN model, personality is comprised of three major dimensions: These descriptive dimensions have psychophysiological roots in which cortical arousal causes extraversion, visceral brain activation causes neuroticism, and gonadal hormones and enzymes cause psychoticism.
Psychology 12 marker the search for a model of individual differences in personality, many theorists have suggested criteria for a good model.
In particular, Eysenck distinctively suggests that an adequate model of personality must have two interlocking aspects: From this perspective, Eysenck further claims that the PEN model constitutes a paradigm in personality research.
To support the theory, proponents of the PEN model e.
In the course of the research, some theorists e. Nevertheless, the PEN model deserves a good evaluation for its contribution to the development of personality psychology. Distinctively, the PEN model Psychology 12 marker advocates the scientific process for evaluating theories with experimental evidence.
This paper will summarize and evaluate the PEN model, focusing especially on Eysenck's theory of individual differences in human temperament and Gray's reformulation of Eysenck's theory. Eysenckhowever, focuses on the temperament aspect of personality in his PEN model.
For better understanding of the PEN model, therefore, the study should begin with its description or taxonomy of personality or temperament. As Eysenck states, "In any science, taxonomy precedes causal analysis" p. In the course of taxonomy, any organisms can be organized into groups based on characters and their relationships.
Eysenck describes in plain terms how taxonomy in the study of personality can be achieved using the correlational technique called factor analysis: In the case of personality study the organisms concerned are human beings, preferably randomly chosen, or with sex, age and other restrictions; the characters are traits, measured by experiment, by rating, by self-rating, or in some other way e.
We can correlate traits over subjects, or subjects over traits, giving us groups of people showing similarity over traits, or groups of traits, cohering as factors over people.
We can then look at the traits or people having the highest factor loadings in order to better identify the trait clusters. However, Eysenck further supposes that traits themselves intercorrelate and make up higher-order factors or superfactors, which Eysenck calls "types.
At the very bottom level of the hierarchy are behaviors such as talking with a friend on a single occasion. At the second level are habits such as talking with friends on multiple occasions, which are comprised of recurring behaviors.
The third level of the hierarchy is that of traits or factors such as sociability, which are comprised of intercorrelated sets of habits. At the top of the hierarchy are superfactors or dimensions of personality such as extraversion, which are intercorrelated sets of traits or factors.
Eysenck suggests three such superfactors: The PEN model is based on the principle of "aggregation," in which measures will have higher reliability if they are comprised of many items Eysenck, That is, each superfactor in the PEN model is comprised of many different factors, habits, and behaviors, and thus reliability of measurement is increased.
The PEN model is also based on the state-trait distinction. That is, the superfactors of extraversion, neuroticism, and psychoticism at the top level of the hierarchy are stable, whereas behaviors such as talking with a friend on a single occasion at the bottom of the hierarchy are changeable across time and situation.

In this respect, the distinction between levels is very important for the analysis of personality in the PEN model. In this respect, Eysenck strongly advocates that there are only three major dimensions or superfactors in the description of personality: That is, each person does not necessarily have either percent or zero percent of extraversion, neuroticism, or psychoticism.
An individual may show some degree of these superfactors on the continuum. A person may have high extraversion, moderate neuroticism, and low psychoticism.
Eysenck afor example, provides empirical evidence to support this "dimensional or continutiy hypothesis" for psychoticism p. Following are three interesting points Eysenck a suggests after studying psychosis: Psychotic symptoms and illnesses do not form completely separate diagnostic entities, unrelated to each other, but are genetically related and form a general cluster with severity of illness the major distinguishing markerIn previous Psychology Today blog posts, Lack of eye contact is the earliest marker for Source: DenisNata/Shutterstock.
