It is widely argued that presenting stimuli of similar durations preceding the targets in a time perception task would influence its perceived duration. A potential explanation for this is comparable to other perceptual modalities that participants adapted to stimuli of similar duration, resulting in an aftereffect. The pooled activities of adapted neurons influence a time-related decision. However, the aftereffect may also affect the reference duration of time bisection tasks and time reproduction tasks used in previous studies, leading to inaccurate estimations. The present study aims to overcome this methodological limitation using a time production task without presenting any time reference and measuring the produced duration in a pre-post time adaptation manner. This modification also allowed us to study whether our mental reference to time will be affected by time adaptation. Further, an adaptation model will hypothesise a change in perceptual sensitivity, which will also be studied in this study. Ninety participants with normal or corrected to normal vision will complete a time adaptation task and a time production task. The time adaptation task is a between-subject factor including three adapting durations – 0.5, 1 or 2s. In contrast, the time production task is a within-subject factor that participants will be asked to produce 0.5, 1 and 2s before and after the time adaptation. The produced durations and their standard deviation will be analysed to study the potential adaptation effect in terms of duration and sensitivity.
