Personality evaluation

The Personality Assessment System (PAS) is a descriptive model of personality formulated by John W. Gittinger. The system has been used by scientists in studying personality and by clinicians in clinical practice. A major feature of the PAS is that a personality profile can be systematically interpreted from a set of Wechsler Scales subtest scores.

The PAS has two aspects which distinguish it from other personality models. They are the use of the Wechsler subtests, an objective test, to determine a personality and the use of a developmental model in which the description of personality includes development through adolescence.

Krauskopf has proposed that differential aptitudes are the "cause" of personality differences. The reason is that people prefer to use aptitudes they feel they are better at than ones where they feel weaker. Krauskopf calls this hypothesis "radical" because so little attention has been paid to the idea. With this "radical hypothesis", the use of an intelligence test, the Wechsler Adult Intelligence Scale to obtain personality information makes sense.
