Psychophysical Parameters in Time and Numerosity Perception Induced by Chunked Stimuli

We separately measured the psychophysical parameters (points of subjective equality and Weber fractions) for time perception and numerosity perception with different chunked stimuli (collinearity, illusory contours, and biological motion) to investigate whether time and numerosity perceptions share a common representation. The data is stored in tabular form, and the EXP column indicates stimuli with different contrasts (H for high, L for low) or different number of points (13 or 41).We additionally incorporated results from a supplementary control experiment presented in the Supplementary Materials, where the biological motion stimuli were scrambled using a different procedure than in the main experiment.
