Abstract : A series of experiments are reported which were designed to evaluate (a) the effects of multiple responses and certainty estimates on visual information integration, (b) the effects of movement induced noise on visual information integration, and (c) bisensory (visual and auditory) information processing. With respect to 'a', it was found that the integration model of the theory of signal detectability overestimated the improvements in discrimination resulting from additional observations and contrary to expectation, probabilistic multiple response proved detrimental to discrimination. The reasons for these unexpected findings were discussed. With respect to 'b', the results showed that discrimination performance could be improved with stimulus movement and the various considerations dealing with ratios of information and interference were discussed. Finally, a considerable amount of research performed with bisensory information processes showed a clear and consistent bisensory effect. Further, bisensory performance tended to be better with nonredundant visual and auditory information. (Author)
