TL;DR: It is shown that vowels are perceived as shorter when attention is divided between two tasks, as compared to a single task control condition, which demonstrates that vowel duration is explicitly estimated using a central general-purpose timer.

TL;DR: It is shown that fast contrast adaptation, which can be observed in the retina, induces a change in apparent duration and this pattern of results indicates a major role for the magnocellular pathway in the neural encoding and representation of visual time.
Abstract: Traditionally time perception has been considered the product of a central, generic, cognitive mechanism. However, evidence is emerging for a distributive system with modality-specific sensory components (Johnston et al. 2006; Morrone et al. 2005). Here we show that fast contrast adaptation, which can be observed in the retina, induces a change in apparent duration. The perceived duration of a sub-second interval containing a 50% luminance contrast drifting pattern is compressed when it follows a high (90%) as compared to a low (10%) contrast interval. The duration effect cannot be attributed to changes in latency at onset relative to offset, can be dissociated from the effect of contrast context on apparent speed or apparent contrast per se and it occurs in a retinocentric frame of reference. The temporal compression is limited to high drift temporal frequencies (≥10Hz) and is not observed for equiluminant chromatic stimuli. This pattern of results indicates a major role for the magnocellular pathway in the neural encoding and representation of visual time.

TL;DR: The present study deconstructs the visual component of the Schutz and Lipscomb illusion, showing that cross-modal influence depends on visible cues signaling an impact event, and the illusion is controlled primarily by the duration of post-impact motion.
Abstract: Contrary to the predictions of established theory, Schutz and Lipscomb (2007) have shown that visual information can influence the perceived duration of concurrent sounds. In the present study, we deconstruct the visual component of their illusion, showing that (1) cross-modal influence depends on visible cues signaling an impact event (namely, a sudden change of direction concurrent with tone onset) and (2) the illusion is controlled primarily by the duration of post-impact motion. Other aspects of the post-impact motion—distance traveled, velocity, acceleration, and the rate of its change (i.e., its derivative, jerk)—play a minor role, if any. Together, these results demonstrate that visual event duration can influence the perception of auditory event duration, but only when stimulus cues are sufficient to give rise to the perception of a causal cross-modal relationship. This refined understanding of the illusion’s visual aspects is helpful in comprehending why it contrasts so markedly with previous research on cross-modal integration, demonstrating that vision does not appreciably influence auditory judgments of event duration (Walker & Scott, 1981).
