The study focuses on the correlation of Szondi’s driving forces in a person with microgenesis of perception of JACFEE set of stimuli by female students (11 subjects). Method: the subjects were exposed to Ekman’s JACFEE set of stimuli (with varied time intervals of 16 msec, 34 msec, 49 msec, 66 msec) in background noise conditions. We have found that microgenesis of perception of the JACFEE set of stimuli involves a chain of phases, in the course of which the mechanisms of perception follow in succession.
