Performance of concurrent tasks: a psychophysiological analysis of the reciprocity of information-processing resources

C Wickens, A Kramer, L Vanasse, and E Donchin

The resources allocated to a primary and secondary task are reciprocal. Subjects performed a tracking task in which the discrete displacements of the tracking cursor could be used to elicit event-related brain potentials. As the resource demands of the tracking task were increased, potentials elicited by the task-defined events increased in amplitude, whereas those elicited by secondary task auditory stimuli decreased.
