Abstract
The relationship between time orientation, depth orientation and locus of control. The purpose of this study was to find an application for the 4-D theory within the field of personality, by establishing the relationships between locus of control, time orientation and depth orientation. The hypotheses set with regard to these relationships were generally confirmed, and significant differences were found between the two sexes. This study provides further evidence of the scientific value of the 4-D theory as a general classification theory of human behaviour, and also stresses the role of control relationships in different life situations as important explanatory variables in the study of behaviour.
