Personality is the particular combination of emotional, attitudinal, and behavioral response patterns of an individual. Different personality theorists present their own definitions of the word based on their theoretical positions. Psychologists such as Freud, and Erickson have attempted to come up with personality theories.
Measuring personality
Personality can be determined through a variety of
tests. This may be done through the Minnesota Multiphasic Personality Inventory
Rorschach Inkblot test, or the Thematic Apperception Test (TAT) The most
popular technique is the self-report - a series of answers to a questionnaire
that asks people to indicate the extent to which sets of statements or
adjectives accurately describe their own behavior or mental state.
Biology of personality
Anatomical structures located in the brain contribute
to personality traits. For instance, the frontal lobes are responsible for
foresight and anticipation. In addition, certain physiological functions such
as hormone secretion also affect personality. For example, the hormone
testosterone is necessary for sociability, affectivity, and aggressiveness.
Extraversion and
happiness
Personality is usually broken into components
called the Big five, which are openness to experience, conscientiousness,
extroversion, agreeableness, and neuroticism (or emotionality). These
components are generally stable over time and appear to be attributable to a
person’s genetics rather than the effects of one’s environment.
