ABSTRACT
Clinical neuropsychology represents an increasingly well-defined and wellrespected specialty within the neuroscientific community The field has enjoyed great success not only in contributing to scientific knowledge about brainbehavior relationships, but also in applying such knowledge through the provi sion of humane and effective assessment, treatment, and advocacy services for persons with central nervous system (CNS) impairment. Of all these activities, assessment of the behavioral and cognitive effects of brain disease has been by far the most common applied task performed by neuropsychologists (Meier, 1974), and a great number of testing instruments have emerged over the past few decades. These instruments, known as neuropsychological tests, represent formal observation-measurement systems in which behavior is examined under certain specified conditions and evaluated against normative or individual com parison standards (cf. Lezak, 1995).
