One female subject drank beer with four female confederate models and two participant observers in a small town tavern. A single subject repeated measures reversal design was used. Condition 1 indicated subject baseline drinking rate. For the first intervention one confederate modeled at a rate 50% less than the subject's baseline rate. Interventions II and III were identical to Intervention I except that two confederates modeled at a rate 50% less than the subject's baseline rate for Intervention II and four confederates modeled at a rate 50% less than the subject's baseline rate for Intervention III. Interventions were separated by returns to baseline. The study was concluded with a final return to baseline. There was no change in subject drinking rate as a function of either one or two confederates modeling the 50% rate. However, when four models drank at the lower rate, subject drinking rate matched that of the four confederate models. Implications and suggestions for further research on modeling are presented.
一名女性受试者在一个小镇酒馆里与四名女性同伙模特以及两名参与观察人员一起喝啤酒。采用了单受试者重复测量反转设计。条件1表示受试者的基线饮酒率。在第一次干预中，一名同伙以比受试者基线率低50%的速率进行示范。干预II和干预III与干预I相同，只是在干预II中有两名同伙以比受试者基线率低50%的速率进行示范，在干预III中有四名同伙以比受试者基线率低50%的速率进行示范。各次干预之间穿插着回归基线阶段。研究以最后一次回归基线结束。受试者的饮酒率并未因一名或两名同伙以低50%的速率进行示范而发生变化。然而，当四名模特以较低速率饮酒时，受试者的饮酒率与四名同伙模特的饮酒率相当。文中还提出了对示范进行进一步研究的意义和建议。
