A translational evaluation of component skills for the establishment of multiply controlled intraverbals

Abstract

Intraverbal behavior is a type of verbal behavior in which the response form has no point-to-point correspondence with its verbal stimulus. However, the form and occurrence of most intraverbals is under the control of multiple variables. Establishing this form of multiple control may depend on a variety of preestablished skills. The purpose of Experiment 1 was to evaluate these potential prerequisites with adult participants using a multiple probe design. The results suggest that training was not required for each putative prerequisite. In Experiment 2, probes for all skills were conducted following convergent intraverbal probes. The results showed that convergent intraverbals only emerged when proficiency of each skill was demonstrated. Finally, Experiment 3 evaluated alternating training of multiple tact and intraverbal categorization. The results showed that this procedure was effective for half of the participants.
