The repetition effect in judgments of temporal duration across minutes, days, and months.
Three experiments assessed the stability of the repetition effect in time judgment. In Experiment 1, subjects (N = 18) produced intervals ranging from 8 to 31 sec in a two-phase procedure with a five min rest between phases. In Experiment 2, subjects (N = 20) made verbal estimates of intervals ranging from 8 to 20 sec with a 48-hour delay between phases. Experiment 3 involved daily productions by three subjects of intervals ranging from 8 to 54 sec over several months. The slope of the psychophysical function increased across phases in Experimental 1, declined (as expected for estimation) across days in Experiment 2, and increased across months in Experiment 3. It was concluded that the repetition effect is relatively permanent and thus more similar to habituation than to sensory adaptation.
