Assesses visuo-spatial short term working memory The Corsi block-tapping test is a psychological test that assesses visuo-spatial short term working memory . It involves mimicking a researcher as they tap a sequence of up to nine identical spatially separated blocks.
The visuo-spatial sketchpad is responsible for holding onto the visual and spatial qualities of a vivid image in your working memory, and the degree of vividness is directly affected by the limits of the sketchpad.
The introduction of stimuli which were hard to verbalize, and unlikely to be held in long-term memory, revolutionized the study of VSTM in the early 1970s. [6] [7] [8] The basic experimental technique used required observers to indicate whether two matrices, [7] [8] or figures, [6] separated by a short temporal interval, were the same.
In 1974 Baddeley and Hitch proposed a "working memory model" that replaced the general concept of short-term memory with active maintenance of information in short-term storage. In this model, working memory consists of three basic stores: the central executive, the phonological loop, and the visuo-spatial sketchpad.
Visuospatial processing refers to the "ability to perceive, analyze, synthesize, manipulate and transform visual patterns and images". [2] Visuospatial working memory (VSWM) is involved in recalling and manipulating images to remain oriented in space and keep track of the location of moving objects.
The cognitive tests used to measure spatial visualization ability including mental rotation tasks like the Mental Rotations Test or mental cutting tasks like the Mental Cutting Test; and cognitive tests like the VZ-1 (Form Board), VZ-2 (Paper Folding), and VZ-3 (Surface Development) tests from the Kit of Factor-Reference cognitive tests produced by Educational Testing Service.
Baddeley and Hitch's model of working memory. In 1974 Baddeley and Hitch [11] introduced the multicomponent model of working memory.The theory proposed a model containing three components: the central executive, the phonological loop, and the visuospatial sketchpad with the central executive functioning as a control center of sorts, directing info between the phonological and visuospatial ...
For example, Hughes and Zimba [21] conducted a similar experiment, using a highly distributed visual array and did not use boxes to mark the potential locations of the target. There was no evidence of a gradient effect, as the faster responses were when the cue and target were in the same hemifield and slower responses when they were in ...
