ABSTRACT
There are two aspects of the work presented in Donchin and Isreal’s chapter. First, the people need to consider the status of electrophysiological work as a whole. Second, they need to consider the implications of the particular work done at Illinois and presented in this chapter. There is, however, one real and important danger in the use of evoked potentials for mental assessment. The most basic paradigm used in Donchin’s lab is that of choice reaction time. The speed-accuracy trade-off in choice reaction time is also one of the main topics in the Donchin and Isreal paper. The planning mechanism in Greeno’s theory is its most important psychological contribution of a general nature. Some reaction-time or eye-movement studies of adults might lead fairly naturally to a process model of the task that could then be used to understand the errors made by children.
