“…In addition, no consistent definition of self-reward or selfpunishment has been used across the various laboratory analogue stud ies, Hence, in the following review, self-reward and self-punishment are defined as the application of an appetitive or aversive stimulus following a response. The stimulus may be self-selected, selfadministered, or self-managed (e.g., Bass, 1972;Skinner, 1953;Thoresen & Mahoney, 197^;Weiner & Dubanoski, 1975)• Self-applied consequences in laboratory analogue studies have included tangible (e.g., candy), conditioned (e.g., a green light), and covert (e.g., self-commendation and self-criticism) stimuli (Weiner & Dubanoski, 1975;Dorsey, Kanfer & Duerfeldt, 1971;Haynes & Kanfer, 1971;respectively). In the present review, the terms reinforcer and reward are used synonymously.…”
