ABSTRACT

In the early days, when our —eld consisted of experimental psy-chologists applying the principles of behavior to “subjects” they encountered in the residential units of institutions, there was no question about where the responsibility lay; it was clearly with the employer. ‹ese pioneer behavior analysts most o¤en had no training in clinical psychology. ‹ey believed that behavior could be changed using procedures derived from learning theory. ‹e “client” (although that term was not used initially) was their employer. In some cases, the parents of a child were the “clients.”
