Effects of Response Spacing on Acquisition and Retention of Conditional Discriminations
Porritt, Matthew; Van Wagner, Karen; Poling, Alan
Journal of Applied Behavior Analysis, v42 n2 p295-307 Sum 2009
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. (Contains 3 figures.)
