A theoretical reconciliation of competing views of time perception.

Abstract: The time-perception literature is oriented around two opposing traditions, one of which, set forth by Ornstein in 1970, views time estimation as linearly and positively related to stimulus complexity, while the other, as published by Priestly in 1968, sees time as essentially linearly but negatively associated with the experiential complexity with which given intervals are filled. However, careful reading of the literature suggests that, contrary to the Ornstein and Priestly models, a linear correlation between stimulus complexity and time perception should not be expected to fully describe the range of possible relationships. What researchers appear to have ignored is the interrelated impact on time perception of the widely reported inverted-U effects of stimulus complexity and the conceptually related dimension of extroversion. With these latter considerations, comparative time perception thus becomes not a linear but rather a curvilinear, U-shaped function of both personality and stimulus complexity dimensions. The conceptual reconciliation growing out of the present literature review thus offers an explanation for previously reported empirical inconsistencies and suggests the redirection of future comparative time perception research.

Methadone Maintenance: An Assessment of Potential Fluctuations in Behavior between Doses

Abstract: Thirty methadone maintenance outpatients were measured 1 and 25 hours after ingestion of methadone on auditory threshold, distance perception, simple and differential reaction time, time perception, attention span, and short-term memory. The results revealed a small but statistically significant difference between the two tests for distance perception. In addition, treatment interacted with preparatory interval on differential reaction time and with sex on attention span.

Comments on current ratio-setting models for time perception.

Abstract: This paper is concerned with the analysis and interpretation of ratio-setting data. Ratio-setting data have been used in support of the conclusion that time perception is not veridical. In the present paper, new ratio-setting data are presented and it is argued that the existing ratio-setting models do not allow the psychophysical law for time to be derived.

Effect of density and environmental noise on perception of time, the situation, oneself and others.

Abstract: The effects of density, intrusion of one's personal space, sex of subject, group composition, and environmental noise on the perception of time, the situation, oneself and others were investigated in this study. Generally, the results indicated that (1) both density and the intrusion of personal space concurrently affect the perception of crowding, (2) the physical factors interacted with the social and personal factors to affect the perception of several aspects of the situation, and (3) the environmental noise did not, for the most part, affect the perception of the situation.
