ABSTRACT
This chapter presents a number of the more commonly measured events studied in cognitive psychophysiology, noting too that a mature science of covert processes no doubt would include a variety of other measures. It starts with the primary division between response events and neurophysiological processes, such that the general term “covert processes” includes both behavioral and nervous system phenomena. Measures of covert nonoral responses during linguistic processing are extremely valuable, especially EMGs from such somatic regions as the fingers, the preferred arm, and from the leg. Particularly interesting for us is the monitoring of covert finger activity in individuals who are proficient in dactylic language, such as deaf individuals or teachers of the deaf. The chapter discusses the second major category, neurophysiological processes. It considers the psychophysiological characteristics of some of the more important covert processes in greater detail.
