CANTAB - Spatial Working Memory
Basic Characteristics
- Description
The CANTAB Spatial Working Memory test asseses a person's ability to retain spatial information and manipulate remembered items in working memory. The test is considered a sensitive measure of frontal lobe and executive dysfunction.This is a self ordered task which also assesses heuistic strategy. The test take approximately 8 minutes to complete. A number of colored squares are shown to the participant on a screen. The aim of the test is that by touching the boxes and using a process of elimination you will find one blue 'token' in each of a number of boxes. These blue tokens are used to fill an empty column. The number of boxes is gradually increased until the participants is searching for a total of eight boxes. The color and position of boxes used are changed from trial to trail to discourage use of stereotyped search strategies. There are 24 outcome measurs including errors, touching boxes that have been found to be empty, revisitng boxes already found to contain a tooken, a measure of strategy, and latency measures. Studies indicate that poor performance on this spaial working memory task is a common factor in prepsychosis.
