ABSTRACT
Some results in the literature suggest that crossmodal attention is very sensitive to the features of the experimental protocol. The current work examined the possible contribution of the asynchrony between the onset of the cue and the target (SOA) and the kind of task performed by the observer to the manifestation of crossmodal attentional effect. In a first experiment, a target (Gabor patch), whose spatial frequency had to be discriminated, was presented 133 or 159 ms after an auditory cue, in a close location on the same side or in a distant location on the opposite side. The crossmodal attentional effect was observed only for the 159 ms SOA. In a second experiment, the SOA was again 133 ms, but the location of the target had to be discriminated, instead of its spatial frequency. A crossmodal attentional effect was observed. The results of these two experiments indicate that crossmodal attentional effect depends on the SOA and the task. It takes longer to develop when the task requires the discrimination of the spatial frequency of the target than the discrimination of its location.
