It remained to be identified that increasing processing load would result in higher variance in temporal information process. The roles of memory and task difficulty in duration discrimination were investigated in auditory and visual modality in this study. Participants were asked to judge whether or not comparison duration was standard duration under four loading conditions. Results revealed that increases in standard duration in memory within blocks led to more discrimination errors, but increases in modality did not. More importantly, this memory loading effect on duration discrimination varied with the difficulty levels. Results confirmed central roles of memory and task difficulty in temporal information processing. Finally, the modality effect was significant, with discrimination being better with auditory signals than visual ones in each of the four loading conditions, which was attributed to the mechanism of modality.
