Spatial Span (SSP)

Spatial Span assesses visuospatial working memory capacity.

Memory tasks

Task format

White squares are shown on the screen, some of which briefly change colour in a variable sequence. The participant must then select the boxes which changed colour in the same order that they were displayed by the computer (for the forward variant) or in the reverse order (for backward variant). The number of boxes in the sequence increases from two at the start of the test, to nine at the end and the sequence and colour are varied through the test.
