Modeling the Auditory Capture Effect in a Bimodal Synchronous Tapping

Synchronous tapping to simultaneously presented asynchronous visual sequence and auditory sequence is more attracted to the concurrently presented auditory sequences than the reverse. This we will call the auditory capture effect (ACE). This study examined ACE over a wide range of sequence IOI (500 ms, 1000 ms, 1500 ms). Moreover, a model fitting the response time (RT) data was considered. The model best fit was the Gabor function, which is the product of a sine and a Gaussian. The model was shown to have a good fit with the variety of the RT data transition. The psychological meaning of the model and the model's prediction of the fluctuation of taps will be discussed.
