Object-based inhibitory priming in preview search: evidence from the "top-up" procedure.

Visual search in a conjunction task can be facilitated if half the distractor items are previewed prior to the other half of the distractors and the target item. Here, we investigate the nature of this preview by using a top-up procedure, which presents an initial preview followed by a secondary preview after a period of time (the offset period). In Experiment 1, we demonstrate that increasing ...

Top-up search and the attentional blink: A two-stage account of the preview effect in search

An inefficient visual search task can be facilitated if half the distractor items are presented as a preview prior to the presentation of the remaining distractor items and target. This benefit in search is termed the preview effect . Recent research has found that a preview effect can still occur if the previewed items disappear before reappearing again just before the search items (the ‘‘top-...

Effects of foveal priming and extrafoveal preview on object identification.

The results of three different experiments suggested that the relation between an object in the fovea on fixation n and an object subsequently brought into the fovea on fixation n + 1 affects the time to identify the second object. In Experiment 1 we extended previous work by demonstrating that a previously seen related priming object speeded the time to name a target object even when a saccade...

Top-down control and bottom-up priming

The present study explored the mechanisms involved in the contingent capture phenomenon using a variant of the classic precueing paradigm of Folk et al. (1992). Rather than keeping the target fixed over a whole block of trials (as traditionally done with contingent capture experiments), we encouraged participants to adopt a top-down set before each trial. If top-down attentional set determines ...

Surface-based constraints on target selection and distractor rejection: Evidence from preview search

In preview search when an observer ignores an early appearing set of distractors, there can subsequently be impeded detection of new targets that share the colour of this preview. This "negative carry-over effect" has been attributed to an active inhibitory process targeted against the old items and inadvertently their features. Here we extend negative carry-over effects to the case of stereosc...
