was developed in the early 1970s as a visuospatial counterpart to the verbal-memory span task (Milner, 1971). Over the years, it has frequently been used to assess visuospatial short-term memory performance in adults (e.g. Smyth & Scholey, 1992), children (e.g. Orsini, Schiappa, & Grossi, 1981), and patients with neuropsychological deficits (e.g. Vilkki & Holst, 1989).

The original Corsi apparatus consisted of a set of nine identical blocks (3 X 3 X 3 cm) irregularly positioned on a wooden board (23 X 28 cm). The experimenter points to a series of blocks at a rate of one block per second. Subsequently, the participant is required to point to the same blocks in their order of presentation. The length of the block sequences increases until recall is no longer correct.

Numerous variations have since been employed in both display characteristics (e.g. colour, number and size of the blocks, block placement, size of the board) and test administration (e.g. presentation rate, block sequences, recall order, scoring technique) (for a review, see Berch, Krikorian, & Huha, 1998).

CONDITIONS

Experimental conditions are the subsets of an experiment that define the relevant experimental manipulation.

CONTRASTS
No contrasts have yet been associated.


In the Cognitive Atlas, we define a contrast as any function over experimental conditions. The simplest contrast is the indicator value for a specific condition; more complex contrasts include linear or nonlinear functions of the indicator across different experimental conditions.

INDICATORS
No indicators have yet been associated.


An indicator is a specific quantitative or qualitative variable that is recorded for analysis. These may include behavioral variables (such as response time, accuracy, or other measures of performance) or physiological variables (including genetics, psychophysiology, or brain imaging data).
