Pigeons were exposed to a repeated acquisition procedure in which no delays were imposed and rate of responding was relatively high. They also were exposed to conditions in which delays were arranged between trials within chains or between completed chains, and rates of responding were lower. Number of trials, rate of reinforcement, difficulty of the discrimination, and motivating operations were held constant. Terminal accuracy was highest under the no-delay condition, in which rate of responding was highest. Effects of trial spacing on retention were mixed and depended on whether delays were imposed between trials within chains or between completed chains. These findings provide basic-research support for the rapid presentation of trials in direct instruction and for rate building in precision teaching.
鸽子接受了一种重复的获取程序,在这个程序中没有施加延迟,并且反应速度相对较高。它们还接受了在链内或完成的链之间安排延迟的条件,并且反应速度较低。试验次数、强化率、辨别难度和激励操作保持不变。在无延迟条件下,反应速度最高,终端准确性最高。试验间隔对保持的影响是混合的,取决于在链内或完成的链之间是否施加了延迟。这些发现为直接教学中快速呈现试验和精确教学中建立反应速度提供了基础研究支持。
