Instructions, discrimination procedures, and sources of reinforcement were manipulated in order to determine the bases for the maintained "non-reinforced" imitations observed in generalized imitation research. Six girls received imitation training from two experimenters. One experimenter modelled only reinforced responses; the other modelled only non-reinforced responses. The children imitated all responses when no reinforced alternative was available, even though results of choice procedures and special instructions clearly demonstrated that they discriminated reinforced from non-reinforced responses. Instructions not to perform non-reinforced imitations immediately eliminated these behaviors. It is suggested that social setting events may be largely responsible for generalized imitation.
为了确定在广义模仿研究中观察到的持续“未强化”模仿的基础,我们操纵了指导说明、辨别程序和强化来源。六位女孩接受了两位实验者的模仿训练。一位实验者仅对强化反应进行建模;另一位实验者仅对非强化反应进行建模。当没有强化的替代方案时,孩子们模仿所有的反应,尽管选择程序和特殊指导的结果清楚地表明他们可以辨别强化和非强化的反应。不进行非强化模仿的指示立即消除了这些行为。有人认为,社会环境事件可能在很大程度上导致了广义模仿。
