The role of response in spatial attention: direct versus indirect stimulus-response mappings.

Recent research has suggested that inhibition of return (IOR) develops more quickly when subjects must respond with an eye movement than when they make a manual response to the target (Perception and Psychophysics 62 (2000) 1512-1524). Four spatial cueing experiments were conducted where subjects had to indicate the location of visual targets. Within each of the oculomotor and manual modalities, responses could be either directed towards the target (saccade or pointing) or had a more complex stimulus-response (S-R) mapping. For both saccadic and manual responses, IOR onset was delayed as the required S-R mapping became more indirect. This finding further emphasizes the role of response-related processes in spatial attention. Possible explanations for this pattern of results are considered, including the notion that activity in prefrontal cortex, needed for execution of such abstract S-R mappings, may influence the time course of reflexive spatial cueing effects.
