Differential observing responses (DORs) are additional response requirements used to promote orientation to a stimulus in a discrimination task. Farber and Dickson (2023) recently provided a DOR taxonomy, and these authors reported that no prior research has compared the effects of distinct DOR requirements. We compared the effects of two DOR…

This study investigated the effects of tact prompts on the acquisition and retention of divergent intraverbal responding to categorical questions involving conditional discriminations. A 6-year-old boy with autism participated in the study. A multiple probe design across behaviors was used. A tact-prompt procedure was implemented. The results…

The study compared the effectiveness of a traditional training procedure (least-to-most restrictive prompt sequence) and a prescriptive training procedure (utilizing ongoing behavioral assessment data to identify discriminative stimuli) with four severely/multiply handicapped students (ages 11-19). Results indicated both procedures were effective…

Two time-delay conditions for teaching complex visual discriminations to 14 normal preschoolers, 12 with mild mental retardation, and 11 with moderate mental retardation were compared. Results indicated that for all populations and stimuli, time delay of multiple dynamic distinctive-feature prompts produced learning, while time delay of the single…

Teachers and teacher educators seem to be little aware of some major concepts about instruction that provide important insights into the central requirements for learning. A common misconception is that motivation has to do with wanting or desiring. It is instead attention to stimuli that is influenced by two powerful agents--(1) suspense,…
