A target was presented at the cued
location (eccentric condition) or at the location 8.
Consequently, if IOR is a bias against attention returning to a previously attended location, no IOR should be observed until attention leaves the cued
location (Klein, 2000; Posner & Cohen, 1984).
Therefore, allocation of attention through spatial cuing results in more accurate and faster processing of information in the space surrounding the cued
Lambert, Spencer, and Mohindra (1987), for example, found that the degree of attention capture elicited by a peripheral cue which indicated likely contralateral target appearance was reduced when participants were informed that the target was unlikely to appear at the cued
location (relative to the group of participants who were not informed of the contingent relationship between cue and target locations).
According to Posner and colleagues, visual attention may be first oriented towards the cued
location in an obligatory and automatic manner.
An unexpected target, the nuclear weapon, was presented twice in each block of trials; it was never cued
directly but was presented concurrently with a target object that was cued
(once precisely and once imprecisely).
Following this logic, target detection is faster for valid than invalidly cued
targets because attentional resources are assigned to the validly cued
target location prior to target onset.
d) How does the order in which targets are detected vary when some targets are cued
and some are not?
According to our results, the information given by the irrelevant cue was used to privilege the processing of the stimuli presented inside the cued
geometric shape, in a way analogous to what happens with a spatial cue.
Sometimes their detection was aided by cuing, but not all targets were cued
, and occasionally nontargets were cued
One of the peripheral boxes is flashed before the target appears thus summoning attention to this location, and responses to the target are usually faster when they appear at this cued
location than when they appear at the uncued location.
When the density of global distractors is greater than 0%, the local area is cued
only with nonequivalent densities of local and global distractors (e.
