The experimenter conducted three experiments to compare incidental language acquisition of familiar and non-familiar stimuli, and asses the effects of specific pairing experiences on the emergence of bidirectional naming (BiN) for familiar and non-familiar stimuli. In Experiment I the experimenter assessed the numbers of accurate untaught listener…

Activity schedules, guided compliance, and differential reinforcement are often used to reduce transition-related problem behavior in children with autism. One potential way to increase the effectiveness of these procedures when transitioning children from preferred to nonpreferred activities is to alter the motivating operations for…

The effects of 2 forms of response interruption and redirection (RIRD)--motor RIRD and vocal RIRD--were examined with 4 boys with autism to evaluate further the effects of this intervention and its potential underlying mechanisms. In Experiment 1, the effects of motor RIRD and vocal RIRD on vocal stereotypy and appropriate vocalizations were…

In the following paper, two experiments are reported based on the relation between adult approvals as conditioned reinforcers and the number of vocal verbal operants, specifically tacts, mands, wh questions, sequelics, and conversational units emitted by children diagnosed with developmental disabilities. In Experiment I, following an experimental…

Brief experimental analyses (BEA) have been used to identify reading interventions to increase the oral reading fluency (ORF) of students having difficulty learning to read. Four interventions, repeated reading, listening passage preview, phrase drill, and contingent reinforcement were implemented with four elementary aged students performing…

Behavioral momentum theory provides a quantitative account of how reinforcers experienced within a discriminative stimulus context govern the persistence of behavior that occurs in that context. The theory suggests that all reinforcers obtained in the presence of a discriminative stimulus increase resistance to change, regardless of whether those…

The effects of preferred stimulation on the vocal stereotypy of 2 individuals were evaluated in two experiments. The results of Experiment 1 showed that (a) the vocal stereotypy of both participants persisted in the absence of social consequences, (b) 1 participant manipulated toys that did and did not produce auditory stimulation, but only…

The use of high-probability (high-p) request sequences has enjoyed support in the applied behavioral literature as a method to increase compliance. Based on the theory of behavioral momentum, high-probability sequences increase the rate of responding, and subsequent rate of reinforcement, within a response class. This increase in density of…
