Abstract
The Inhibition of Return (IOR) effect manifests as slowed responses to targets at previously cued compared to uncued locations (Posner & Cohen, 1984; Klein, 2000). Most research indicates the effect to be inhibitory in nature, and research has typically involved identifying the components and the locations involved in generating the IOR effect. The Attentional Momentum (AM) theory of IOR instead implicates a facilitatory component involved in the IOR paradigm, where participants’ expectations about the relationship between a cue and target influence their reaction times (Pratt, Spalek, & Bradshaw, 1999). However, support for the AM theory is limited on the basis of a) inconsistent findings in subsequent follow up research, and b) the suggestion that eye movements were driving findings that support the AM theory. The current set of experiments examines the level of support for the AM theory of IOR after accounting for these issues.
