Abstract

Previous work has suggested that our perception of time is plastic and dependent on the distance of the stimulus to our body. For example, Annelli et al (2015) showed that stimuli presented in peri-personal and far space are judged differently and that this distance-effect on time perception can be shaped by training participants with a tool that effectively extends the reachable space. We here aimed to replicate and extend these results using a paradigm in which we tested time perception at multiple distances from the body prior to and following active tool-use training. In two experiments, we probed 66 participants on three temporal tasks (visual bisection, visual categorization and auditory categorization) for stimuli presented at three distances from the body (60 cm, 120 cm and 240 cm). In between testing blocks, participants performed blocks of active tool-use training whereby they used short and long mechanical grabbers to move coins at a distance of 120 and 200 cm from the body. For each task we tested for an effect of spatial distance, tool-use training and their interaction. Contrary to our expectations, our results revealed that time perception seems to remain uninfluenced by the proximity of the stimulus to the body and is not shaped by extension of the action-related body by tool-use training. Hence they call into question to what degree and how robustly time perception is shaped by the distance of the probe to the body and how malleable this is by extension of the peripersonal space by tool-use training.
