• Baseline Assessment of Speech: For the first five days of baseline, the authors assessed operant levels of rate and content of speech among the groups by observing their verbal responses. The snack was given noncontingently, regardless of whether they verbalized or not. • Reasons for Different Results Between Group A and Group B in Experiment 1: The authors attributed the differences in responding to a difference in response effort. However, it is likely that there are inter-subject differences between the groups that also contributed to the varied outcomes. • Reinforcement of Correspondence Condition: The reinforcement was contingent upon the correspondence between what the participants said and what they did. In other words, reinforcement was provided only when their verbal responses matched their actions. • Results of the Three Experiments: In each of the three experiments, for there to be correspondence between saying and doing, contingencies had to be directly placed on responses that matched. This means that reinforcement depended on the alignment of verbal responses with actual behavior. • Operant Class: An operant class is a class of behavior that is defined...
