ABSTRACT

Time and space are intimately related in real life, as can be seen from the nearly universal use of spatial concepts in time words across cultures. However, whether the form of spatiotemporal representations relies on the linear or on the logarithmic scale is still under debate. In addition, there is a lack of research investigating the development of spatiotemporal representations. Here, we examined the form of spatiotemporal representations across 6-8-year-olds, 9-11-year-olds, and adults using a novel timeline estimation paradigm. We asked participants to view a three-minute-long video clip and mark the temporal distance of a specific scene of the video on a horizontal timeline. We found non-linearity between their estimates and stimulus temporal distances, which decreased as the participants’ ages increased. Six-to-eight-year-old children showed the greatest non-linearity compared to other age groups, and there was no significant difference in the magnitude of non-linearity in estimation between 9-11-year-olds and adults. These results imply that humans might have a logarithmically compressed spatial representation of time across age groups.
