Abstract

The temporal binding window refers to the time frame within which temporal grouping of sensory information takes place. Sense of agency is the feeling of being in control of one’s actions, and their associated outcomes. While previous research has shown that temporal cues and multisensory integration play a role in sense of agency, only one previous study has directly assessed whether individual differences in the temporal binding window and sense of agency are associated. The current study aimed to accumulate evidence in relation to the degree to which individual differences in the temporal binding window correlate with individual differences in the sense of agency window. To assess sense of agency, participants pressed a button triggering, after a varying delay, the appearance of the circle, and reported their sense of agency over the effect. To assess the temporal binding window a double-flash illusion was performed. Unexpectedly, the temporal binding window and the sense of agency window were shown not to be associated. However, both of these processes were modulated by applying occipital tACS at either 14Hz or 8Hz. We found 14Hz tACS stimulation was associated with narrower temporal biding window and sense of agency window. Overall, our results suggest the temporal binding window and the time window of sense of agency are related. They also point towards a possible underlying neural mechanism (alpha peak frequency) for this association.
