Inhibition of Return in Manual Pointing Movements

Motor IOR revealed for reaching

“…Whereas Fischer et al (2003) observed IOR for all types of manual responses to peripheral targets, they found no evidence of IOR for central arrowhead targets for any type of manual response. The authors therefore concluded that the presence of IOR for manual responses in general-and for reaching movements in particular-is attributable to sensory rather than motor effects.…”

“…An alternative explanation for the lack of IOR observed by Fischer et al (2003) is that peripheral cues are insufficient to generate a motor form of IOR in the reaching control system, unlike the case for the oculomotor control system (e.g., Taylor & Klein, 2000). It has been argued that peripheral cues automatically engage saccade preparation in the oculomotor system even if no movement is executed (cf.…”

“…A small set of studies has focused on IOR for manual responses to targets signaled by central arrows (CowperSmith, Eskes, & Westwood, 2013;Fischer et al, 2003;Taylor & Klein, 2000), thereby avoiding concerns that IOR results from a spatially localized sensory processing deficit-that is, where the processing of sensory information is selectively delayed at or near the peripheral target location (Dorris et al, 2002;Fecteau & Munoz, 2005;Fischer et al, 2003;Posner & Cohen, 1984;Taylor & Klein, 1998Wang et al, 2012) 1,2…”

“…Recognizing that central arrows can be used to probe for the presence of motor IOR, Fischer et al, (2003) attempted to measure IOR for various types of manual responses instructed by either peripheral or central arrowhead targets. In both target conditions, participants were instructed to ignore an uninformative peripheral cue, which could occur in one of two locations, and then respond with one of four types of manual responses (simple or choice keypress responses and simple or choice reaching movements).…”

Peripheral stimuli generate different forms of inhibition of return when participants make prosaccades versus antisaccades to them

“…Klein and Hilchey (2011) offered a framework for organizing the numerous dissociations in the literature. When the task is strictly covert, slower RTs are observed principally when the cue and target occupy the same or proximal locations (Taylor & Klein, 2000;Fischer, Pratt, & Neggers, 2003;. This effect is commonly referred to as attentional/perceptual (Taylor & Klein, 2000) or, synonymously, as occurring nearer the input end of the processing continuum (Hilchey, Hashish, MacLean, Ivanoff, Satel, & Klein, 2014).…”
