Sensory uncertainty increases central tendency. A typical subject’s data for visual (a) and auditory (b) stimuli. To quantify the central tendency, reproduced durations are linearly fitted to stimulus durations. A smaller slope value means a larger central tendency. Each dot represents reproduced duration in one trial. (c) Group results of the central tendency across modalities and noise levels. The regression slope smaller than 1 means the central tendency occurred. Error bars indicate SEM.
