The temporal relationship between sensory events plays a crucial role in establishing causal link between them, for example inferring a common cause. In the current study, we manipulated the probability of co-occurrence of various visual stimuli pairs to see whether this manipulation would affect participants’ ability to separate the two elements of a pair in time, when presented asynchronously. We used a simultaneity judgment task, with a learning phase, in which participants (N=14) saw synchronously disappearing shape-pairs, and a test phase, in which three types of pairs (learned, newly combined, novel) were presented, while the asynchrony between the disappearance of the elements was manipulated. Contrary to earlier results with cross-modal stimuli, a lower proportion of simultaneity judgments, as quantified by shorted temporal binding windows was reported for the learned pairs than for the newly combined or novel visual pairs indicating an increased probability of unisensory binding.
