摘要：Some individuals who engage in self-injurious behavior (SIB) also exhibit self-restraint. In the present study, a series of three functional analyses were conducted to determine the variables that maintained a participant's SIB, one without restraint items available, one with a preferred and effective form of self-restraint (an airplane pillow) available noncontingently, and one with this item delivered contingent on SIB. Results suggested that SIB was reinforced by escape and by access to self-restraint materials, self-restraint appeared to be maintained by automatic reinforcement, and continuous access to highly preferred restraint materials effectively suppressed SIB.
