Experiment 1: Audio-visual coherence

  • Christian Wolf
Part of the BestMasters book series (BEST)


Experiment 1 was designed to answer the question whether humans integrate auditory and visual information to form a motor command for smooth pursuit eye movements. If auditory information was integrated and beneficial for the pursuit command, we would expect pursuit to require a lower visual signal for a given gain. This should have been reflected in lower PSE values if both information move coherently (Congruent condition). If the integration was based on the strength of motion rather than its direction, the same effect should have been observed, if both move in opposite directions (Incongruent condition). We included a condition with a stationary sound in order to check for effects of the presence of any auditory signal.
