Abstract		The successful development of evoked potential tests of sensory function depends on the absence of individual differences, particularly with regard to component latency. The event-related potentials (ERPs) associated with cognitive function, however, demonstrate considerable inter-subject variability which may reflect individual differences in cognitive ability, or strategies adopted when performing different tests. Support for this view can derived from studies of short-term memory, and learning of complex visuo-spatial tasks. In a study of the latter cognitive function, which involved the learning of a different key-press in response to visual presentation of each letter of the alphabet, the ERPs of those who learned the task quickly were significantly different from those who did not. This difference was apparent during the early stages of learning when the performance of the two groups could not be distinguished.
