“…For example, Ferraro et al (1971) arranged TDMTS in an identity matching task where the delay increased by 2 s after two consecutive correct trials and decreased by 2 s after one incorrect trial. Sidman, Stoddard, Mohr, and Leicester (1971) used a TDMTS where one correct response increased the delay and one incorrect response decreased the delay by 4 s. In the present experiments, we arranged 12 titrating steps where the step size was 500 ms in 0 s to 6 s delays and 250 ms in 0 s to 3 s delays. Due to software restrictions, the accuracy criterion to increase the delays was 3 out of 3 correct trials in AC and BC training and a minimum of 5 out of 6 correct comparison choices in subsequent training phases.…”

“…Materials and procedures were also developed to assess listener behavior; similar to traditional receptive language tasks. To evaluate the variables controlling verbal behavior, Sidman, Stoddard, Mohr, and Leicester (1971) recommended that evaluators hold the stimulus or the response constant across testing conditions. Therefore, the odd-numbered items on the BNT, a previously validated measure, were incorporated into five assessment measures (listener behavior, echoic, tact, intraverbal, and vocal and selection-based mand assessment) by holding the stimulus items constant and varying the controlling variables to match those that characterize each verbal operant (see Appendix A for stimuli and Appendix B for detailed assessment instructions).…”

Approximately 5% of older adults have a dementia diagnosis, and language deterioration is commonly associated with this disorder (Kempler, 2005). Several instruments have been developed to diagnose dementia and assess language capabilities of elderly adults. However, none of these instruments take a functional approach to language assessment as described by Skinner (1957). The purpose of this study was to develop and evaluate a function-based assessment for language deficits of older adults. Thirty-one participants were categorized into a control group (n 5 15) and a dementia group (n 5 16) based on their score on the Dementia Rating Scale-2. Individuals with dementia performed significantly worse on the tact assessment than those without dementia. Participants from both groups performed better on measures of tacts than intraverbals or mands, even though topographically identical responses were required in these assessments. The data provide support for Skinner's conceptualization of functionally independent verbal operants.

“…A second possibility was revealed when we found that aphasic subjects who had improved nearly to perfection in matching printed words to identical printed words and pictures to identical pictures were still incapable of matching the words to their corresponding pictures (Sidman, 1971;Sidman, Stoddard, Mohr, and Leicester, 1971). When these subjects were presented with "language symbols" and asked to do identity matching, they succeeded, but when they were asked to do nonidentity matching with these same language symbols, they failed.…”
