The Effect of Working Memory Rehabilitation on Visual Memory and Memory Span

Introduction: Age-related cognitive decline or cognitive aging is largely the result of structural and functional decline in specific areas of the brain, but lifestyle also contributes to this cognitive decline. The aim of this study was to investigate the effect of working memory rehabilitation on visual memory and memory span in ageing.  Methods: This was a quasi-experimental study with pret...

A probabilistic model of visual working memory: Incorporating higher order regularities into working memory capacity estimates.

When remembering a real-world scene, people encode both detailed information about specific objects and higher order information like the overall gist of the scene. However, formal models of change detection, like those used to estimate visual working memory capacity, assume observers encode only a simple memory representation that includes no higher order structure and treats items independent...

A model of visual working memory in PFC

We present a model of visual working memory in ventral prefrontal cortex. Activation in ventral PFC consists of reverberating activity. Representations in ventral PFC are conjunctions of location and (partial) identity representations. With many objects, representations in ventral PFC interfere, which results in loss of information. Therefore, the number of objects in working memory is limited....

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 ...

Visual working memory contaminates perception.

Indirect evidence suggests that the contents of visual working memory may be maintained within sensory areas early in the visual hierarchy. We tested this possibility using a well-studied motion repulsion phenomenon in which perception of one direction of motion is distorted when another direction of motion is viewed simultaneously. We found that observers misperceived the actual direction of m...
