Delayed prompting can produce errorless discrimination learning. There is inherent in the procedure a disparity in reinforcement density which favors unprompted over prompted responses. We used three schedules of reinforcement to investigate the impact of reinforcement probability on transfer of stimulus control. One schedule of reinforcement was equal prior to and following a prompt (CRF/CRF), the second favored unprompted responses (CRF/FR3), and the third favored responses following the prompt (FR3/CRF). Experimental questions concerned the probability of errors, the probability of transfer, and the rate of transfer in the context of delayed prompting. Transfer was accelerated when reinforcement probability favored anticipatory responding. The schedule that favored prompted responses did not prevent a shift to unprompted responding. Errors were infrequent across procedures. Reinforcement probability contributes to but does not entirely determine transfer of stimulus control from a delayed prompt.
延迟提示可以产生无错误的辨别学习。该程序中存在强化密度的差异,这种差异有利于未提示的反应而非提示后的反应。我们使用了三种强化程序来研究强化概率对刺激控制转移的影响。一种强化程序在提示之前和之后是相等的(连续强化/连续强化,CRF/CRF),第二种有利于未提示的反应(连续强化/固定比率3,CRF/FR3),第三种有利于提示后的反应(固定比率3/连续强化,FR3/CRF)。实验问题涉及错误概率、转移概率以及在延迟提示背景下的转移速率。当强化概率有利于预期反应时,转移会加速。有利于提示后反应的程序并没有阻止向未提示反应的转变。在各个程序中错误都很少见。强化概率有助于但不能完全决定从延迟提示中进行刺激控制的转移。
