Trait Theories & Informal Approaches to Personality

Personality Traits and Personality Temperaments

Another way of analyzing an individual's personality is in terms of personality traits. Trait theories are actually formal assessment tools, researched and designed by such famous psychologists as Allport, Cattell, and Eysenck ( These theories are often applied in an informal manner, however, which is why they are described in this course as "informal approaches" to personality. 

A trait is a quality individuals have in common with each other, though one person may have more of this quality than another. Examples of traits are friendliness, outgoingness, sensitivity, trust, etc. One of the most famous evaluation tools is the Meyers-Briggs test. 

A temperament is generally thought of as a set of characteristics, or traits, a person shares, as exhibited in behavioral patterns.  One available online temperament assessment tool is called the Keirsey Temperament Sorter (O), similar to the popular Myers-Briggs Type Indicator test (O). If interested in using the Keirsey tool, follow the instructions on the website and use it more for fun than for self-diagnosis. You will need to register before completing the 70-item Keirsey test but there is no cost to do so.

Personality Types

Sometimes people's personalities are described through generalized personality types; you may already be familiar with the Type A and Type B personality types, for instance. The stereotypical Type A personality is characterized by impatience, aggression, anger, hostility, and the need for control over situations. Individuals labeled as "Type A" may experience more cardiovascular complications (high blood pressure, heart disease, e.g.) than an individual who does not exhibit these personality characteristics. The Type B personality type is associated with patience, being "laid back" or calm, and much less time-urgent. The Type C personality type fits the person who may be very busy and task-driven, but who may also have a tendency to be passive and hold anger inside. provides a little more information on differentiating Type A, Type B, and Type C personality types (R).

Are you Type A? If interested, take a test to assess your Type A tendencies at the Body Mind Queendom Page (O). Please use this test not as a diagnosis, but as an understanding into the components which make up the "Type A" personality. (O)


The attitudes we exude to friends, family, acquaintances, and strangers often reveal a lot about who we are. An example of an attitude is the optimist/pessimist point of view. An optimist usually has a positive bent on potentially stressful situations, while a pessimist usually has a negative outlook. As many may already be familiar, an optimist considers a glass filled halfway as "half full" while a pessimist considers the same glass "half empty." Optimistic and pessimistic attitudes not only demonstrate the effects on a person's outlook on life, but may also affect a person's state of health. Travel to a Mayo Clinic abstract presented through the UK's Centre for Confidence, about how optimism and pessimism assessed in the 1960's compared with the health status of the same individuals 30 years later  (R).  Rob Stein, a Washington Post blogger, describes similar connections between attitude and health in his The Health Hazards of Pessimism 2009 post (O).
