Abstract :
Orthogonal polynomial trend analysis allows the extraction of event-related brain activity on basis of a few stimulus presentations enabling the study of time on task changes in event-related brain activity. The impact of this information on the interpretation of conventionally averaged event-related potentials is illustrated by comparing a high functioning autism group to matched controls
