Baddeley created the working memory model as a way of explaining short term memory. He proposed that it consisted of 3 subsections, a central executive, a phonological loop and a visuo-spatial sketchpad, these subsystems are then further fractionated. Logie (1995) proposed that the visuo-spatial sketchpad is divided into two components; a visual cache and an inner scribe. The inner scribe contains information on movement and spatial awareness. Whereas the visual cache stores information about visual form.
Evidence for the fractionation of the working memory model in general has come from patients who have suffered head injuries. Patient K.F. had impairment in their verbal short term memory but their visual short term memory was still perfectly …show more content…
In a study of brain damaged adults, they were found to be highly impaired at performing a spatial task but there performance on visual tasks were found to be above median (Della Sala et al, 1999). This is strong evidence for the visuo-spatial sketchpad being split into subcomponents.
From looking at the brain, it is suggested that there could be different anatomical locations within the brain. This is one for spatial coding and one for the visual aspects of the brain (Jaiswal, Ray & Slobounov, 2011). Showing that there could be two distinct but complimentary …show more content…
These cubes had the numbers 1 to 9 written on them. The materials used for Recall Designs were eight non-nameable, black ink designs printed on A5 size paper, a stopwatch and eight pieces of blank paper.
Design
Both the Recall Designs and Corsi Span test were experimental designs. Both tests are between subjects as they examine the differences between individuals. For the Corsi test the dependent variable was the number of sequences recalled correctly, and for the Recall Designs it was the overall score across the eight items. For both tests the independent variable was the age of participants.
Procedure
Both the adult and children participants were tested individually in a classroom setting. The Corsi test required the experimenter to tap out a sequence of blocks, at a rate of one block per second and the participant had to repeat this exactly for it to be correct and move to the next sequence length. The sequence will then be increased by one number, there are three attempts at each sequence length, and if the participant fails all three then the test is ended. The board must be positioned so the numbers are not visible to the
