Abstract : A series of experiments were designed to determine the effects of bisensory information processing under conditions of varying channel redundancy and task difficulty. The dependent measures were proportion correct and choice response time. The Ss were requested to discriminate among series of ambient sea noises. While an intersensory facilitation effect was noted, it was shown to be a joint function of amount of experience, task difficulty and redundancy with the nonredundant conditions resulting in the greatest degree of intersensory facilitation. A number of theories were discussed, and it was concluded that Broadbent's filter theory provided the best description of the data. (Author)
