Stimulus-response probability and inhibition of return

Does Oculomotor Inhibition of Return Influence Fixation Probability during

Inhibition of return in manual and saccadic response systems.

When nonpredictive exogenous visual cues are used to reflexively orient covert visual spatial attention, the initial early facilitation for detecting stimuli at cued versus uncued spatial locations develops into inhibition by 300 msec following the cue, a pattern referred to as inhibition of return (IOR). Experiments were carried out comparing the magnitude and time course for development of IO...

Bilingualism influences perceptual inhibition more than stimulus-response inhibition

Bilinguals outperform monolinguals at suppressing task-irrelevant information, with advantages likely deriving from cognitive mechanisms employed during bilingual processing. In this study, monolinguals’ and bilinguals’ inhibition performance was compared on two nonlinguistic inhibition tasks: a Stroop-like task (with perceptual conflict among stimulus features) and a Simon-like task (with stim...

Exploring the effect of stimulus characteristics on location-based inhibition of return using abrupt and ramped stimulus presentation

A recent study illustrating the importance of sensory influences on inhibition of return (IOR) found stimuli biased towards the parvocellular (P) pathway produced greater IOR while stimuli biased towards the magnocellular (M) pathway produced less IOR (Brown, 2009; Guenther & Brown, 2007). The present study used a different sensory manipulation (temporal onset/offset) to further explore this re...

Orienting of attention and Parkinson's disease: tactile inhibition of return and response inhibition.

There is growing evidence for cognitive impairments in Parkinson's disease (PD), including in the orienting of attention and inhibition of return (IOR). IOR refers to the slowing of a response to a target stimulus presented in the same location as a previous stimulus. While some researchers have reported normal levels of visual IOR in PD patients using cue-target tasks, others have reported sig...
