Interaction of environment and personality: A test of Holland's theory

Abstract

Tested J. L. Holland's assumption that personality variables interact with environment. The following hypotheses were investigated: (a) for males who leave engineering (n = 27) there is a personality change different from that found among those who remain in engineering (n = 25); and (b) for males who leave or remain in engineering, the personality development is different from that of males in a 2-yr college (n = 22). Analysis of Omnibus Personality Inventory scores indicates that 2 dimensions represented differences between groups: intellectual independence and practical inclination. Transfers to arts and sciences from engineering became more realistic, nonjudgmental, intellectual, liberal, and skeptical of orthodox religious beliefs. 2-yr students showed greater variability in their personality change scores and a loss in their liking for reflective and abstract thought. Results tend to support Holland's theory of vocational development. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
