Judgment of Filled and Unfilled Durations: Intersensory Factors

Abstract

Previous studies have shown a consistent intersensory difference in absolute judgments of the duration of continuous auditory and visual inputs. More visual than auditory clock time was judged equivalent to specific temporal concepts. Two experiments investigated this intersensory phenomenon further by comparing the judgments of filled auditory and visual durations with the estimation of unfilled intervals bounded by discrete lights and sounds. Auditory durations were judged longer than visual for the filled and unfilled conditions, and filled auditory durations were judged longer than unfilled auditory intervals The intersensory difference in time judgment was independent of stimulus pattern while the filled-unfilled difference was dependent upon sense mode, order effects and internal temporal standard. Stimulus properties must be cons~dered when interpreting the results of time judgment research.

Processing time between visual events

“…In the second case, it is the clock-based variance that differs with the interval structure since the timekeeping period differs: a longer time keeping period results in higher temporal variance. As shown in figure 3, a filled interval might actually be perceived as being longer than an empty one, which is consistent with the timing literature (41)(42) . Finally, it is important to stress that major distortion of perceived duration can be caused by the presentation of successive visual signals.…”

Factors affecting the haptic filled-space illusion for dynamic touch

“…A number of studies have reported a Wlled-duration illusion, i.e., Wlled time intervals judged longer than empty ones (BuVardi 1971;Craig 1973;Goldstone and Goldfarb 1963;Grimm 1934;Otto Roelofs and Zeeman 1951;Thomas and Brown 1974). The illusion has been shown for the auditory modality (clicks and continuous tones), visual modality (Xashes and continuous light), and tactile modality (vibrations applied to the index Wnger; short bursts or continuous vibrations).…”

The slippery context effect in psychophysics: Intensive, extensive, and qualitative continua

“…The ANOVA revealed only two statistically reliable effects: an effect of level, reflecting the increase in judgments with increasing duration [F(3,45) = 233.0, P < .0001], and an interaction of modality x context, reflecting the slippery context effect [F(1, 15) = 8.84, P = .01]. Only one other effect even approached significance: the effect of modality [F(1,15) = 5.99, P = .07], reflecting the well-known tendency for subjects to judge auditory durations as longer than corresponding visual durations (e.g., Goldstone & Goldfarb, 1963).…”
