This study investigated the degree to which inhibition of return (IOR) is influenced when endogenous visual and auditory stimuli are used to specify a target in a cross-modal paradigm. Twelve participants performed rapid manual aiming movements to a target located in right (red target) or left (green target) hemispace. On each trial, the target was randomly specified by either an endogenous visual (i.e., a red or green light in the centre of the two targets) or auditory (i.e., a recorded verbal “red” or “green”) stimulus. A previous target by previous modality interaction revealed that the time required to plan a motor response was greater when participants returned to the same target, but only when those movements were cued in the other sensory modality. IOR was completely absent for consecutive auditory trials. These results indicate that, for endogenous cues, IOR effects may be more pronounced in cross-modal situations.
