Indeterminance in human behavior

The view held in PARTheory that, by their very nature, human behavior and development are to some degree indeterminate and therefore probabilistic; they do not follow strict laws or forces such as those postulated in Newtonian physics. Rather, PARTheory postulates that mental activity (see mental representation) coordinates all human experience. That is, experience is given meaning through mental activity. Experience is thus susceptible to many interpretations. Individual variability in the interpretation of experience may be a major source of partial indeterminance of behavior and development. This variability in the interpretation of experience contributes to PARTheory's emphasis on a phenomenological perspective. (See culture; the probability model; universals in human behavior)
