Event Abstract Back to Event Effects of visually induced expectations on auditory processing: dependency on expectancy and rule complexity Riikka Lindström1*, P. Paavilainen1, T. Kujala1 and M. Tervaniemi1 1 Department of Psychology, University of Helsinki, Finland Our senses do not operate separately: information from one modality can influence perception in another modality. The present study determined by means of event-related potentials whether visual information can induce an expectation of a forthcoming sound. Twelve subjects were shown pairs of pictures and sounds that followed artificial rules. The rule pairing a sound and a picture were based either on a simple association (a particular picture was paired with a particular sound) or on a more abstract association (a particular picture was associated with category of sounds). Occasionally the rule was violated by presenting incongruent picture-sound combinations. To investigate whether the expectations created by visual stimuli influence the processing of the forthcoming sound, the paired sounds and pictures were presented either simultaneously (no possibility for expectation) or the sound 300 ms after the picture onset (enough time for the expectation to arise). The incongruent picture-sound pairs elicited an N2, presumably composed of the mismatch negativity and N2b, whose latency was shorter (from 250 ms to 500 ms) when there was a delay between the visual and auditory stimuli. Both the delay between pictures and sounds and the intangibility of rule influenced the amplitude of this negative deflection. With 300 ms delay between the stimuli, a frontally negative and posteriorly positive P300 was elicited at 550 ms after onset of sound, suggested to reflect conscious recognition of the deviation. The amplitude of the P300 was also modulated by the intangibility of the rule linking auditory and visual stimuli together. These results show that human brain can form auditory expectations on the basis of visual information and, further, that both temporal aspects and cognitive demands during an audiovisual deviance detection task modulate the brain processes involved.
