Time estimation as a function of stimulus complexity and personality

following the theoretical model originally proposed by Hogan (1978), this study tests the existence of a "U"-relationship between stimulus complexity and time estimation such that time "filled" with simple or complex stimuli is perceived as more extended than when the same time is "filled" with stimuli that is of a moderate complex nature. In addition, the present study assumes that this relationship can be better explained by considering the personality variables of extroversion and introversion and their interaction with stimulus complexity. The results confirmed the existence of a quadratic relationship between stimulus complexity and time (< = 0.001). The relationship between information processing in terms of stimulus complexity, personality variables, and the theme of time estimation is discussed.
