The effects of processing time and processing rate on forgetting in working memory: Testing four models of the complex span paradigm
|
Four models of working memory processes in the complex span paradigm were tested: The task-switching model of Towse, Hitch, and Hutton (1998), the interference account of Saito and Miyake (2004), and two versions of the time-based resource-sharing model of Barrouillet, Bernardin, and Camos (2004). On the basis of a reading span paradigm that used segmented sentences, the effect of processing time on the recall of words was investigated while the amount of processing was held constant. Two con...

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

Working memory contributions to relative clause attachment processing: A hierarchical linear modeling analysis
Memory & Cognition
; An eye-movement-monitoring experiment tested readers' responses to sentences containing relative clauses that could be attached to one or both of two preceding nouns. Previous experiments with such sentences have indicated that globally ambiguous relative clauses are processed more quickly than are

When visual and verbal memories compete: Evidence of cross-domain limits in working memory
Psychonomic Bulletin & Review
; Recently, investigators have suggested that visual working memory operates in a manner unaffected by the retention of verbal material. We question that conclusion on the basis of a simple dual-task experiment designed to rule out phonological memory and to identify a more central faculty as the

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

Individual capacity differences predict working memory performance and prefrontal activity following dopamine receptor stimulation
Cognitive, Affective and Behavioral Neuroscience
; Dopamine receptors are abundant in the prefrontal cortex (PFC), a critical region involved in working memory. This pharmacological fMRI study tested the relationships between dopamine, PFC function, and individual differences in working memory capacity. Subjects performed a verbal

Such studies address the question of whether specific learning disabilities coincide with specific working

Training of working memory performance in dyslexics
Psychology Science
; Summary Reading and writing are based on complex adaptive processes of perception, attention, and memory. A failure in learning to read can be due to a dysfunction of a single process, a number of serial processes, or to the interaction of parallel processes. This article focuses on the role of

Influence of working memory on adult age differences in matrix reasoning.
British Journal of Psychology
; Speculations about the role of working memory in adult age differences in cognition can be traced at least as far back as Welford's (1958) book (see Salthouse, 1990, for a review of research on adult age differences in working memory). It has only been in the last several years, however, that

Towards an artificial phonological loop: An assistive device for working memory and attentional control
Applied Bionics and Biomechanics

The primate working memory networks
Cognitive, Affective and Behavioral Neuroscience
