Abstract

Graduated stimulus change and trial-and-error methods were used to train a two- choice discrimination task to two groups of profoundly retarded individuals. The results were compared across four size- and four shape-discrimination tasks. Graduated stimulus change was more efficient than trial-and-error on the initial problem, continued to be more efficient across tasks, and was more efficient on two reversal problems. However, experience with similar problems was shown to be an important factor.

跨任务的试错和分级刺激变化过程的比较
采用渐进式刺激变化和试错法对两组深度智障个体进行了两项选择辨别任务的训练。结果通过四个大小和四个形状辨别任务进行比较。在初始问题上,渐进式刺激变化比试错法更有效,在不同任务间持续更有效,在两个反转问题上更有效。但是,处理类似问题的经验是一个重要因素。
