Abstrakt: We evaluated the use of a blocked-trials procedure to establish complex stimulus control over intraverbal responses. The participants were four young boys with a diagnosis of autism who had struggled to master intraverbals. The blocked-trials procedures involved presentation of stimuli in separate trial blocks. The trial blocks gradually reduced in size contingent upon correct responding, until the stimuli were presented in quasi-random order. All participants acquired multiple discriminations with the blocked-trials procedure, although additional procedures were needed to teach the first discrimination with two participants. Following acquisition of multiple discriminations, two participants acquired a novel discrimination with quasi-random presentation of stimuli, and a third participant demonstrated discriminated responding in intraverbal probes.
Competing Interests: The authors declare that they have no conflict of interest.All procedures performed in studies involving human participants were in accordance with the ethical standards of the Human Subjects Institutional Review Board at University of North Texas and with the 1964 Helsinki Declaration and its later amendments or comparable ethical standards.Informed consent was obtained for all individual participants included in the study. Participants could leave the study at any time, and assent was obtained during each session.
