Imaging technologies such as positron emission tomography (PET) and magnetic resonance imaging (MRI) present unparalleled opportunities to investigate the neural basis of autism spectrum disorder (ASD). However, challenges such as deficits in social interaction, anxiety around new experiences, impaired language abilities, and hypersensitivity to…

The study compared the effectiveness and efficiency of constant time delay and system of least prompts in teaching two eight-year-old students with autism to name numerals. Results indicated that both procedures were effective but the constant time-delay procedure was more efficient with these two subjects. (Author/DB)

Four nonverbal autistic boys (ages 11-16) were successfully taught sign language action-object phrases following an intervention composed of prompting, fading, stimulus rotation, and differential reinforcement. The skill generalized to new situations. (Author/DB)

A communication program for autistic children (three to six years old) which increased communication skills in the context of establishing reciprocal communication exchanges involving intensive modeling of verbal responses within joint activity routines and reinforcement based on fulfilling the intent of the child's communication.

The study compared the effectiveness of two different reinforcement conditions to teach speech to severely handicapped nonverbal autistic children (N=4). Findings indicated that reinforcing speech attempts was more effective than reinforcing motor speech sounds in terms of both children's interest and behavior and of improvements in children's…

The study attempted to improve verbal language acquisition for two nonverbal four- and five-year-old autistic children by incorporating natural language interactions and motivational techniques. Broadly generalized treatment gains resulted from use of functional and varied stimuli, natural reinforcers, reinforcement of communicative attempts, and…

The study with four pairs of developmentally delayed preschoolers found a slight but discernible advantage of using the time delay procedure rather than the increasing assistance procedure to teach complex, chained-response self-help skills. Considerable learning also resulted solely from the observation of instruction. (Author/DB)
