ABSTRACT
The basic problem of evaluating the psychologic changes accompanying frontal lobe operations probably will not be solved solely by psychologic methods. The cooperation of all the medical sciences as well as of the cognate basic sciences is essential for a solution of the fundamental problems which psychosurgery has raised. Within the field of psychology itself all the techniques that psychologists have evolved in their various specialties as well as those that they can borrow from adjacent fields must be mustered for the attack on this problem. The basic function of the psychologist doing research with psychosurgery patients may be described as the introduction of quantitative measures for the selection of patients who may benefit by the operation and for estimating changes in behavior following frontal lobe operations.
