Abstract:

Over the past decade considerable strides have been made in explicating the antecedent conditions necessary for the elicitation, and the modulation of the amplitude and latency, of a number of components of the event-related brain potential ERP. We focus in this report on the p300. Much work in our laboratories and elsewhere has begun to elucidate the functional significance of the p300Desmedt, 1980 Donchin, 1981 Pritchard, 1981 Sutton and Ruchkin, 1984. These data contribute to the analysis of cognitive function and are therefore of theoretical interest. However, in this paper we will dwell mostly on the degree to which these psychophysiological measures contribute to issues in two real-world domains communication devices for the motor impaired and the assessment of mental workload of aircraft pilots. Although these two domains may appear to be quite heterogenous they both require relatively rapid communication of information, a problem for which components of the ERP may prove useful. It is important to note that techniques are available in both of these domains that address the communication problem. js
