This study examined if listener behavior and responding by exclusion would emerge after training 3 participants with autism to tact stimuli. Tacts for 2 of 3 stimuli were directly trained using discrete trial training methodology and were followed by an auditory-visual discrimination probe in which auditory-visual discrimination by naming (i.e.,…

Of the diagnostic features of autism, relatively little research has been devoted to restricted and repetitive behavior, particularly topographically complex forms of restricted and repetitive behavior such as rigidity in routines or compulsive-like behavior (e.g., arranging objects in patterns or rows). Like vocal or motor stereotypy,…

Restricted and repetitive behavior (RRB) is more pervasive, prevalent, frequent, and severe in individuals with autism spectrum disorders (ASDs) than in their typical peers. One subtype of RRB is restricted interests in items or activities, which is evident in the manner in which individuals engage with items (e.g., repetitious wheel spinning),…

In response to a previous article proposing perceptual reinforcement of stereotyped movements in autistic and mentally retarded persons, it is argued that this theory fails to take into account biological findings and theory regarding pathological stereotyped acts. An alternative theory derived from neurological concepts is suggested. (Author/DB)

The authors respond to criticism of their paper proposing a perceptual reinforcement of stereotyped movements in autistic and mentally retarded persons. The alternative theory based on neurobiological factors is judged to be insufficiently detailed and inadequate in scope. (Author/DB)

In the current study, momentary time sampling (MTS) and partial-interval recording (PIR) were compared to continuous-duration recording of stereotypy and to the frequency of self-injury during a treatment analysis to determine whether the recording method affected data interpretation. Five previously conducted treatment analysis data sets were…

Three experiments were conducted with two participants with mental retardation that displayed property destruction and stereotypy. The experiments assessed the function of the responses, determined their relationship, and developed a treatment to reduce property destruction. Response blocking reduced property destruction (and attempts), prevented…
