| Abstract: | Contingent social isolation was investigated as a punishment procedure for the disruptive behavior of emotionally disturbed children in a classroom setting. The methodological limitations of previous studies were outlined, and alternatives adopted. Within a reversal and multiple baseline design, contingent social isolation was found to be an effective and relatively specific punisher. By introducing a new observation procedure, “pseudo-timeout”, it was determined that the punishing effect of social isolation was not attributable to observation artifact. A means for resolving the terminological confusion in the present use of timeout and social isolation was recommended. |
