Does gaze cueing produce automatic response activation: A lateralized readiness potential (LRP) study
چکیده انگلیسی


- We investigate whether gaze cueing stimuli produce automatic response activation.
- We measure LRPs in relation to the direction of the gaze cue.
- The gaze cue stimulus did not produce any LRPs.

Previous research has shown that gaze cues facilitate responses to an upcoming target if the target location is compatible with the direction of the cue. Similar cueing effects have also been observed with central arrow cues. Both of these cueing effects have been attributed to a reflexive orienting of attention triggered by the cue. In addition, orienting of attention has been proposed to result in a partial response activation of the corresponding hand that, in turn, can be observed in the lateralized readiness potential (LRP), an electrophysiological indicator of automatic hand-motor response preparation. For instance, a central arrow cue has been observed to produce automatic hand-motor activation as indicated by the LRPs. The present study investigated whether gaze cues could also produce similar activation patterns in LRP. Although the standard gaze cueing effect was observed in the behavioural data, the LRP data did not reveal any consistent automatic hand-motor activation. The study suggests that motor processes associated with gaze cueing effect may operate exclusively at the level of oculomotor programming.
