TASK
Extradimensional shift task
A task in which multiple (typically two) stimuli are presented simultaneously and the subject must select the stimulus that matches the currently relevant rule. The relevant rule alternates or "shifts" among multiple (typically two) rules. The rule represents the relevant task "dimension". The stimulus-response mappings are unique and constant within each possible rule dimension.
