Corsi Blocks

Basic Characteristics

• Description

The Corsi blocks test examines visuospatial short term memory performance in adults and children. In this test 9 identical blocks are placed on a wooden board. An experimentor then points to a series of blocks at a rate of 1 block per second. Participants are asked to point to the same blocks in the same order. The length of the series of blocks increases until participants no longer recall the sequence correctly. This test is widely used in clinical contexts by doctors and psychologists to test for loss of memory function in brain-damaged patients. The test is considered a instrument for measuring spatial memory and noverbal working memory. Variations of this task exist in both display characteristics (e.g. color, number, size of blocks, size of board) and administration (e.g. presentation rate, block sequences, recall order, scoring technique). The Corsi blocks test is widely used in clinical contexts by doctors and psychologists testing for loss of memory function in brain-damaged patients.
