AI Article Synopsis
- Repeated exposure to short or long stimuli affects how we perceive the length of subsequent stimuli, a process known as duration adaptation.
- This study tested duration adaptation for both short (sub-second) and long (supra-second) durations to see if the phenomenon could be observed in longer time frames.
- Findings showed that duration adaptation occurs for both types of durations and suggests that there might be a unified system in our perception of time, regardless of the length of the intervals.
Article Abstract
After repetitive exposure to a stimulus of relatively short duration, a subsequent stimulus of long duration is perceived as being even longer, and after repetitive exposure to a stimulus of relatively long duration, a subsequent stimulus of short duration is perceived as being even shorter. This phenomenon is called duration adaptation, and has been reported only for sub-second durations. We examined whether duration adaptation also occurs for supra-second durations (Experiment 1) and whether duration adaptation occurs across sub- and supra-second durations (Experiment 2). Duration adaptation occurred not only for sub-second durations, but also for supra-second durations and across sub- and supra-second durations. These results suggest that duration adaptation involves an interval-independent system or two functionally related systems that are associated with both the sub- and supra-second durations.
