An operant group procedure significantly increased the frequency of here-and-now affect, feedback, and empathy statements made by two groups of four subjects during ten one-hour sessions, divided into base line, acquisition, extinction, reacquisition and generalization periods. The continously reinforced group showed resistance to extinction, attributed in part to reinforcement by other group members when a subject made reinforceable statements. Failure of the variably reinforced group to replicate this finding was attributed in part to a less adequate conceptual grasp of the reinforcement categories resulting from the reduced feedback associated with a variable ratio schedule. Both groups showed strong generalization effects when subjects were distributed among eight new groups and the new groups and the new subjects' performance was also significantly higher than typical base levels.
一种操作性团体程序显著提高了两组各四名受试者在十个一小时疗程中的当下情感、反馈和共情陈述的频率，这些疗程分为基线期、习得期、消退期、再习得期和泛化期。持续强化组表现出对消退的抵抗力，部分原因是当受试者做出可强化陈述时，其他组成员给予了强化。可变强化组未能重复这一发现，部分原因是与可变比率程序相关的反馈减少，导致对强化类别概念的掌握不够充分。当受试者被分配到八个新组中时，两组都表现出强烈的泛化效应，新组和新受试者的表现也显著高于典型的基线水平。
