Immediately following an event at a peripheral location there is facilitation for the processing of other stimuli near that location. This is said to reflect a reflexive shift of attention towards the source of stimulation. After attention is removed from such a peripheral location, there is then delayed responding to stimuli subsequently displayed there. This inhibitory aftereffect, first desc...

Location-based cuing experiments have shown that inhibition of return (IOR) spreads beyond a cued location but appears to be confined to the cued hemifield by the vertical meridian. Previous studies have also shown that IOR can spread across objects and here we investigate whether an object can be used to mediate the spreading of IOR into the opposite hemifield. Two experiments used a rectangul...

Previous research has reported that the Simon effect (a type of stimulus-response [S-R] compatibility effect) and the inhibition of return effect (IOR; a late cuing effect) do not interact. In this brief report, we analyzed published and unpublished experiments that have examined these effects and found that IOR actually increases the Simon effect. This is a remarkable finding because most fact...

For many, death and its aftermath is a distasteful subject; a subject to be ignored or avoided until suddenly it demands attention. Those who lose a close relative or friend are often left in a state of shock and grief, They are illprepared to handle arrangements for a funeral or burial or cremation—yet they often nzu~t attend to the myriad social and financial details. My own mother’s death la...

Inhibition of return (IOR), slowed responding to targets at a cued location after attention is removed from this location, has been shown to occur both in adults and in infants. To explore suggestion that the timecourse of IOR depends on factors that might affect the efficiency with which attention is removed from the cued location, we compared the performance of young children (5-10-year-olds,...

When the interval between a transient flash of light (a “cue” ) and a second visual response signal (a “target”) exceeds at least 200 ms, responding is slowest in the direction indicated by the first signal. This phenomenon is commonly referred to as inhibition of return (IOR). The dynamic neural field model (DNF) has proven to have broad explanatory power for IOR, effectively capturing many em...

Centrally presented gaze cues typically elicit a delayed inhibition of return (IOR) effect compared to peripheral exogenous cues. We investigated whether gaze cues elicit early onset IOR when presented peripherally. Faces were presented in the left or right peripheral hemifields, which then gazed upward or downward. A target appeared in one of four oblique spatial locations giving the cue and t...

The beha®ior of stationary and mo®ing spatially-periodic patterns in a simple crossflow reactor was simulated and analyzed for a situation in which reactant is supplied continuously along the reactor and a first-order exothermic reactor occurs. The Danck( werts boundary conditions for realistic Le and Pe ®alues. While the unbounded in) finitely long reactor is an asymptotic case used to study t...

Inhibition of return (IOR) refers to the performance disadvantage when detecting a target presented at a previously cued location. The current paper contributes to the long-standing debate whether IOR is caused by attentional processing or perceptual processing. We present a series of four experiments which varied the cue luminance in mixed and blocked conditions. We hypothesised that if inhibi...

It was found [Vision Res. 36 (1996) 2125] that reaction times for repeated targets were longer in detection and location discrimination tasks (inhibition of return; IOR) and shorter in color and orientation discrimination tasks (facilitation of return; FOR). The present experiment, using a more detailed analysis, shows that both IOR and FOR can be found in the discrimination tasks. Overall, the...
