["Spute dich, Kronos, fort den rasselnden Trott..." Reflections on time perception in the psychoanalytic process and at the end of life].

Referring to Goethe's Poem "An Schwager Kronos", the author tries to establish a relationship between the experience of time as lived through in the course of the psychoanalytic process as well as of time as experienced under the impression of the possibly approaching end of one's life. Psychoanalytic theory, however, has only limited possibilities to grasp "time" in psycho-dynamic or psycho-symbolic terms. Nevertheless, the changes in the experience of time, which take place in the course of a lifetime, can often be worked through in a psychoanalytic process focussing on loss, "fear of breakdown" (Winnicott) and hope. This working through contributes to the internalisation of the holding environment, i.e. good inner "saving" objects provided by the therapist. Episodes from Mozart's "Last Year" are used as clinical illustrations.

Need for cognition related to time perception.

Undergraduates who scored high on need for cognition tended to underestimate a 90-sec. filled interval and their number of correct single solution anagrams tended to correlate negatively with estimated time. Subjects high in need for cognition reported the task was easy but enjoyment and prior experience were similar.

Sex differences in time perception.

In an experiment on discrimination of duration of auditory stimuli in the range of milliseconds 16 men and 16 women were tested. Men scored better than women in discrimination of duration as well as in required session time. These results were discussed in terms of the assumption of a neurotransmitter-related internal clock and with respect to sex differences in reaction time.

Time perception: effects of sex and sound intensity on scales of subjective duration.

Six women and six men reproduced ten time intervals varying in logarithmic steps between 1.3 and 20 s. The durations were indicated by white noise of 10, 25, 40 and 55 dB SL, different sound intensities in different sessions. It was found that (i) greater sound intensity entails shorter reproductions, and (ii) reproductions by male observers are shorter than those by female, although for both (i) and (ii) there is an interaction with the standard durations. The data were treated in accordance with the "parallel-clock model" (Eisler, 1975), whereby the parameters of the psychophysical power function are determined from duration reproduction data. As in previous experiments (Eisler, 1975), the data showed a break in the function entailing two segments. The effect of sound intensity could be attributed to the exponent, which was lower for stronger noise, and the effect of sex to the weight coefficient of the upper relative to the lower segment of the psychophysical function, the coefficient being lower for men.

Ethnic differences in time perception: a comparison of Anglo and Mexican Americans.

Social scientists have presented an image of the Mexican American as locked into the present, incapable, or unwilling to project plans and events into the future. This is seen as responsible in part for the lack of social mobility and assimilation exhibited by Mexican Americans. However, there is little empirical support for the contention that Mexican Americans have a restricted sense of future events. The present study compared the temporal perspectives of 31 Mexican American and 41 Anglo American college students. No marked differences were observed.
