Were you paying attention to where you looked? The role of executive working memory in visual search
|
Recent evidence has indicated that performing a working memory task that loads executive working memory leads to less efficient visual search (Han & Kim, 2004). We explored the role that executive functioning plays in visual search by examining the pattern of eye movements while participants performed a search task with or without a secondary executive working memory task. Results indicate that executive functioning plays two roles in visual search: the identification of objects and the c...

The role of spatial working memory in visual search efficiency
Psychonomic Bulletin & Review
; Many theories have proposed that visual working memory plays an important role in visual search. In contrast, by showing that a nonspatial working memory load did not interfere with search efficiency, Woodman, Vogel, and Luck (2001) recently proposed that the role of working memory in visual search

Visual search is slowed when visuospatial working memory is occupied
Psychonomic Bulletin & Review
; Visual working memory plays a central role in most models of visual search. However, a recent study showed that search efficiency was not impaired when working memory was filled to capacity by a concurrent object memory task (Woodman, Vogel, & Luck, 2001). Objects and locations may be stored in

Visual working memory as the substrate for mental rotation
Psychonomic Bulletin & Review
; In mental rotation, a mental representation of an object must be rotated while the actual object remains visible. Where is this representation stored while it is being rotated? To answer this question, observers were asked to perform a mental rotation task during the delay interval of a visual

The role of working memory in attentional capture
Psychonomic Bulletin & Review
; Much previous research has demonstrated that visual search is typically disrupted by the presence of a unique "singleton" distractor in the search display. Here we show that attentional capture by an irrelevant color singleton during shape search critically depends on availability of working memory

Working memory has limited "slots".(Research Roundup)
The Hearing Review
; A new study by researchers at UC Davis shows how our very short-term working memory --memory that allows the brain to stitch together sensory information--operates. The system retains a limited number of high-resolution images for a few seconds, rather than a wider range of fuzzier impressions. The

Individual differences in working memory capacity and visual search: The roles of top-down and bottom-up processing
Psychonomic Bulletin & Review
; Individual differences in working memory capacity (WMC) have been implicated in a variety of top-down, attention-control tasks: Higher WMC subjects better ignore irrelevant distractions and withhold habitual responses than do lower WMC subjects. Kane, Poole, Tuholski, and Engle (2006) recently
