Description
The speed-up of responses to multisensory compared to unisensory signals is typically attributed to target redundancy, where a correct response is triggered by the constituent signal that is processed fastest in a given trial (redundant signal effect; RSE). Here, we show that the RSE is modulated by signal congruency and trial history. We presented congruent or incongruent auditory and visual stimuli and asked participants to respond with the same response to multi- or unisensory target stimuli. We found that the RSE is larger for congruent than incongruent combinations and was also affected by trial history, with a larger RSE following a stimulus switch compared to stimulus repetition. Interestingly, these two effects were additive. Our analysis of the RSE at the distribution level and a large-scale modelling analysis suggest that congruency contributes to the RSE and is independent of trial history effects. Consequently, we consider potential contributors to the congruency modulation of multisensory responses.| Period | 22 Nov 2024 |
