ABSTRACT
Clinical neuropsychology continues to be one of the most popular and fastest growing fields of psychological practice. Neuropsychological assessment developed as a methodology from extending the use of clinical test batteries that had been developed for the purpose of experimentation or the evaluation and characterization of a more broadly defined category of psychopathology. This chapter focuses on the development of various approaches to neuropsychological assessment as they developed from the middle part of the 20th century. There exist a number of excellent summaries of the origins of specific tests and accounts of neuropsychology's pioneers. The experimental sample for Halstead's test battery included neurosurgical patients who had undergone cerebral lobectomies, head-injured patients, and some control subjects. The chapter provides some contributions by emphasizing the development of neuropsychological assessment and some of the major approaches developed in North America that are used today in modern-day practice.
