A neural model of retrospective attention in visual working memory
An informative cue that directs attention to one of several items in working memory improves subsequent recall of that item. Here we examine the mechanism of this retro-cue effect using a model of short-term memory based on neural population coding. Our model describes recalled feature values as the output of an optimal decoding of spikes generated by a tuned population of neurons. This neural ...
متن کاملCommon neural substrates for visual working memory and attention.
Humans are severely limited in their ability to memorize visual information over short periods of time. Selective attention has been implicated as a limiting factor. Here we used functional magnetic resonance imaging to test the hypothesis that this limitation is due to common neural resources shared by visual working memory (WM) and selective attention. We combined visual search and delayed di...
متن کاملEffectiveness of working memory intervention in behavior inhibition and visual working memory of children with Attention Deficit/ impulsive subtype Disorder (ADHD-I)
The aim of the current research study was to determine the effectiveness of working memory intervention on behavioral inhibition and visual working memory in children with symptoms of attention-deficit/impulsivity disorder in Selseleh city. The method was a quasi-experimental pre-test-post-test design with a control group. The statistical population consisted of all boy students of 8-12 years o...
متن کاملRetrospective attention enhances visual working memory in the young but not the old: an ERP study.
Behavioral evidence from the young suggests spatial cues that orient attention toward task-relevant items in visual working memory (VWM) enhance memory capacity. Whether older adults can also use retrospective cues ("retro-cues") to enhance VWM capacity is unknown. In the current event-related potential (ERP) study, young and old adults performed a VWM task in which spatially informative retro-...
متن کاملA Neural Model of Visual Attention
We propose a biologically plausible neural model of selective covert visual attention We show that this model is able to learn focussing on object speci c features It has similar learning characteristics as humans in the learning and unlearning paradigm of Shi rin and Schneider
