Personality development takes place through mutual interactions involving the person and their environment. It can be analyzed and described on three levels: basic dispositions, characteristic adaptations, and personal meanings. The phenomena and processes involved are different on each level. Analyses of this are concerned with what promotes and/or inhibits developmental changes of personality. This article introduces the notion of reasons for great life changes, as well as Zenomena Płużek’s conception of personality development.

The aim of the present study was to investigate the relationship between positive orientation defined as a basic predisposition to perceive and evaluate positive aspects of life, the future and oneself and the Five-Factor Model of personality. Hypotheses postulated positive correlations between PO and extraversion, conscientiousness, agreeableness and openness; a negative correlation was predicted between PO and neuroticism. Two hundred Polish students completed the following measures: SES, SWLS, LOT-R and NEOFFI. The results confirmed correlations between PO and extraversion, conscientiousness, and (...) neuroticism; correlations with openness and agreeableness were not supported. According to canonical correlations, PO shows a clear affinity to the FFM. (shrink)
