Individuals diagnosed with autism spectrum disorder (ASD) who engage in stereotypy may also emit a prior, temporally contiguous, high-risk response to access stereotypic behaviors. For example, the participant in this study who was diagnosed with ASD engaged in a chained response that included elopement, often in unsafe locations, to access light…

The study evaluated the usefulness of 48 hours of Restricted Environmental Stimulation Therapy (REST) as a treatment for eight autistic children (between 5 and 11 years old). Ss were placed in a dimly lit room which contained only a mattress, told to ask for toilet facilities when needed, and then left alone except for when meals were brought in.…

The effect of level of stereotypy on learning a discrimination was examined using a factorial design with high and low levels of stereotypy and three levels of IQ with 30 institutionalized retarded persons. Results indicated the effects of stereotypy were different across the IQ levels. (Author/DB)

The effects of meaningfulness of the stimulus materials and the presence or absence of contextual cues on problem-solving behavior were investigated. Third-graders (N=80) were randomly assigned to one of four conditions and their performance in a series of discrimination problems was observed. Subjects in Conditions I and II responded to stimuli…

Competence in action perception seems to be achieved very early in life. Because research has indicated that competent perceivers of action must be able to discriminate breakpoints in behavior, then recognition memory for breakpoints should be superior to that for nonbreakpoints at all ages where competence in action perception exists. Two studies…

Four experiments were conducted to assess the effects of certain stimulus variables on children's discrimination learning. In general, it was found that word frequency was negatively related to discrimination learning as long as the words were meaningful to the subjects. Moreover, the relationship between word and performance reversed in…

This paper reports to two experiments designed to develop a behavioral procedure to teach young children emergency dialing skills. Experiment 1 evaluated the effects of a behavioral procedure administered by the classroom teachers. In the classrooms training focused upon making phone calls in emergency situations. Six steps in emergency dialing…
