Corsi Block-Tapping Task

Corsi Block-Tapping Task

What is CBTT

The Corsi Block-Tapping Task is widely used for the assessment of visuospatial short-term memory, both in clinical practice and in experimental research settings. Basically, it is a span task and, as such, a visuospatial analogue to the digit span as an index of verbal short-term memory (Lezak, 1995). Originally developed by Corsi (1972), this test entails simple measurements that can be administered quickly and easily, even with patients who are difficult to test.
