Visual foraging with two simultaneous visual working memory templates

Attentional templates in visual working memory.

Most theories of attention propose that we maintain attentional templates in visual working memory to control what information is selected. In the present study, we directly tested this proposal by measuring the contralateral-delay activity (CDA) of human event-related potentials during visual search tasks in which the target is cued on each trial. Here we show that the CDA can be used to measu...

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...

The Effects of Spark Training on Visual-Spatial Working Memory Operation in Children with Mental Retardation

Introduction: Mental retarded children who receive a wide range of health services, representing more than two percent of the population. Mental retardation is associated with significant constraints on mental performance and adaptive behavior as well as perceptual and practical skills. According to the studies, one of the important tools that can affect cognitive abilities, such as memory, is ...

Modeling visual working memory with the MemToolbox.

The MemToolbox is a collection of MATLAB functions for modeling visual working memory. In support of its goal to provide a full suite of data analysis tools, the toolbox includes implementations of popular models of visual working memory, real and simulated data sets, Bayesian and maximum likelihood estimation procedures for fitting models to data, visualizations of data and fit, validation rou...
