![]() ![]() These results have implications for our understanding of visuospatial memory in dyslexia, and also in terms of the administration of the Corsi task to special populations. Related terms: Down Syndrome Long-Term Memory Working Memory Memory. visuo-spatial sketchpad, often referred to as visuo-spatial memory, integrates spatial, visual, and possibly kinesthetic information into a unified. From: Cognition, Brain, and Consciousness (Second Edition), 2010. Our data suggest that, without instruction, people with dyslexia are unable to adopt an effective CB strategy and this is consistent with a deficit in executive function. The visuospatial sketchpad refers to our ability temporarily to hold visual and spatial information, such as the location of a parked car, or the route from home to a grocery store. We present three studies which indicate a consistent dyslexic deficit on CB that can be ameliorated by visual strategy instructions. While people with dyslexia typically show no deficit on CF, CB is rarely presented. Previous research has suggested that, while CF draws on spatial-sequential resources, CB may load executive and distinctly visual processes. ![]() In a widely used measure, the Corsi blocks task, sequences of visuospatial locations can be recalled forwards, in the order presented (CF), or backwards, in reverse order (CB). Experiments are described that demonstrate the separability of visuo-spatial and verbal coding effects. However, the situation regarding visuospatial memory is less clear. The Sketchpad is assumed to be responsible for the setting up and manipulating of temporary visuo-spatial representations, and as such to be an important component in the utilisation of imagery. Impairments in working memory are suggested to be one of the defining characteristics of dyslexia, and deficits in verbal recall are well documented. We termed the third component the visuo-spatial sketchpad, leaving open the issue of whether it was basically visual, spatial, or both. an element or subsystem of working memory utilized for practicing or employing visual, imaginal, or spatial data. ![]()
