It has been shown that sensory-specific or common processes mediate perception and memory. Here we investigated whether the summation operation of temporal duration is specific to sensory modalities. Two filled intervals were presented as intra- or inter-modal sequence (audition–audition; vision–vision; audition–vision; vision–audition). Participants reproduced the sum (0.6–1.1 s) of two intervals. We found that the summation operation of two intervals generally led to an overestimation of the sum, irrespective of conditions. The variations of reproduction were comparable between inter- and intra-modal conditions, indicating no impairment in inter-modal summation of duration. Furthermore, the variations showed positive within-participant correlation between all modality conditions (rs > 0.74). These results suggested that a supra-modal process might mediate the summation of duration. In the subsequent experiment, the similar pattern of results was observed by using short intervals (to be summed to 0.3–0.5 s); however, the intra-modal conditions showed much reduced correlations with other conditions (r = 0.39), which indicated that the summation of short durations might be mediated by sensory-specific processes. In sum, the present results suggest two processes for summation of temporal durations: the sensory-specific process that operates only on short durations, and the other supra-modal process that handles otherwise (i.e., when longer durations are to be summed or when inter-modal summation is required).
