Effects of Reinforcement History on Stimulus Control Relations

Description: Ray (1969) conducted an experiment on multiple stimulus-response relations and selective attention. Ray's (1969) results suggested that stimulus-response relations function as behavioral units. McIlvane and Dube (1996) indicated that if stimulus-response relations are behavioral units the effects of environmental variables on stimulus-response relations should be similar to the effects of environmental variables on single response topographies. This experiment analyzed the effects of reinforcem… more

The Effects of Reinforcing Operant Variability on Task Acquisition

Description: Neuringer, Deiss, and Olson (2000) was replicated and extended to determine the effect of variability contingencies on task acquisition for twelve 7-9 year old children. Subjects first learned to press a computer's shift keys with increasing response variation. Each subject was then exposed to one of three experimental conditions during which they received a point for target responses. Variability condition subjects received additional points on a variable interval schedule for nontarget respon… more

The Effects of Timed Readings on Recall and Comprehension in a Child with Asperger's Syndrome.

Description: The effects of timed readings on recall and comprehension in a child with Asperger's syndrome were examined by employing a multiple-baseline design across two books with reversals. Recall timings consisted of the student's free-say compilation of what she just read. Comprehension tests consisted of the participant's answers to predetermined questions after her recall period. No consequences or feedback was given during any of the conditions. Results indicate that, initially, as the time req… more

Immediate and subsequent effects of fixed-time food presentations on automatically maintained mouthing.

Description: Several studies have demonstrated that fixed-time (FT) schedules of stimulus delivery can function to reduce a variety of behaviors. The purpose of this study was to evaluate the immediate and subsequent effects of FT food deliveries on mouthing. In Phase 1, a preference assessment showed that caramel popcorn, chocolate cookies and pretzels were highly preferred food items. Thus, providing the basis for use of food items during treatment. In Phase 2, a functional analysis showed that mouthing w… more
