The objective of Experiment I was to determine whether establishing conditioned reinforcement for engaging in math for pre-kindergarten students was possible using the three conditioning procedures outlined in previous research for conditioning book stimuli. The purpose of Experiment II was to determine whether this change in preference for…

Manding for preferred items and activities is a critical skill for young children with autism spectrum disorder (ASD). However, little research has evaluated procedures to teach children with ASD to mand with their peers. This study evaluated the effects of a teaching package involving least-to-most prompting to increase peer-directed vocal…

This study examined the functional independence of mand and tact operants in normally developing children and evaluated the role of S[superscript D]s in demonstrating emergent responding. In Experiment 1, 4 children aged 4 to 5 years, were trained to mand or tact using left/right relations, then were tested for the emergence of the untaught…

Studies that have compared the effectiveness of differing prompt types to teach intraverbal responses have yielded mixed results, suggesting that individuals' reinforcement histories with prompt types may influence which prompt will be most effective. The purpose of this study was to test whether programmed increases in exposure to specific prompt…

The purpose of the study was to evaluate the use of a treatment package comprised of a social story, discrimination training, and differential reinforcement with response cost on the vocal stereotypy of one preschooler diagnosed with an autism spectrum disorder. The study took place in a preschool classroom of a public school and was implemented…

We used a delayed non-concurrent pre- and post-intervention probe design to test the effects of a voice conditioning protocol (VCP) with 3 preschoolers with autism on (a) rate of acquisition of listener curricular objectives, (b) observing voices and the presence of adults across 3 settings, (c) selecting to listen to adults tell stories in free…

The purpose of this series of experiments was to evaluate the effects of mixed mand-tact arrangements on the acquisition of mands and tacts in preschool-aged children. In Experiment 1, the effects of three training arrangements (mand-only training, tact-only training, and mand-tact training) were investigated with 3 typically developing children.…

I tested the effects of the absence of an adult on the observational conditioning effect (Greer & Singer-Dudek, 2008). Neutral stimuli (metal washers) did not function to reinforce performance or learning tasks for three preschool age children as determined by a counterbalanced reversal design for the pre-intervention performance tasks and…

The present study examined whether the presentation of stimuli in equivalence relations with consequences increases the operant behavior that produces these consequences. In Experiment 1, both normal words and experimentally trained equivalence stimuli did so with young children. In Experiment 2, results were similar with college students. Here, a…

This study sought to further investigate the effects of an observational intervention for two participants on the reinforcing property of pieces of string. Pre-observational intervention data showed that the neutral stimuli (strings) did not function to reinforce two participants' responding to a performance task or learning three new skills that…

Conditional discrimination is inherent in the intraverbal relation when one verbal stimulus alters the evocative effect of another verbal stimulus and they collectively evoke an intraverbal response. Rarely in research on conditional discriminations have both conditional and discriminative stimuli been vocal verbal and rarely have the responses…

The phenomenon identified as naming is a key stage of language function that is missing in many children with autism and other language delay diagnoses. We identified four children with autism, who, prior to the implementation of this experiment, did not have the naming repertoire (either speaker to listener or listener to speaker) and who had no…

Findings from a study investigating the conditions under which contingency learning games were associated with optimal child and adult concomitant and social--emotional behavior benefits are reported. Participants were 41 preschool children with multiple disabilities and profound developmental delays and their parents or teachers. Results showed…

We report an experiment investigating the effects of conditioning books as reinforcers for observing responses on the learning of textual responses by pre-school children. The independent variable was the acquisition of conditioned reinforcement of observing responses and choice of book stimuli in free play settings where children could choose to…

Few studies have made use of B. F. Skinner's (1957) behavioral analysis of language and precise taxonomy of verbal behavior when describing the controlling variables for the mand relation. Consequently, the motivating operation (MO) has not typically been identified as an independent variable and the nature of a spontaneous mand has been…
