The Effects of the Density of Reinforcement on the Maladaptive Behaviors of a Child With Autism

Description: The present study consists of two experiments that analyze the effects of high and low densities of reinforcemnt on the maladaptive behaviors of a 9 year old girl with autism. The first experiment investigates the isolated effects of density of reinforcement on the frequency of maladaptive behaviors during a motor imitation teaching task. High densities of reinforcement produced fewer occurrences of maladaptive behavior than low densities of reinforcement. Experiment 2 analyzes the effects of d… more

The Effects of Interspersed Trials and Density of Reinforcement on Accuracy, Looking Away, and Self-Injurious Behavior of a Child with Autism

Description: This research examines the effects of task interspersal and density of reinforcement on several behaviors of an autistic 6-year-old boy during the performance of a visual matching task and two auditory matching tasks. Experiment 1 investigated the effects of interspersing high and low accuracy tasks on correct matching responses, positions of matching responses, looking away, and self-injurious behavior (SIB). The effects of interspersed trials were evaluated using an ABAB multiple treatments d… more

Effects of Picture Exchange Training on Communication Topographies

Description: The Picture Exchange Communication System (PECS) has been used with children with autism and other developmental disabilities as an alternative to vocal communication. Some researchers have reported rapid acquisition of picture-exchange requesting as well as increased vocal speech and increased spontaneous social interactions following PECS training. Earlier research has found that although 3 children with autism learned to exchange pictures for preferred items during PECS training, requestin… more

Using a Behavioral Treatment Package to Teach Tolerance to Skin Care Products to a Child with Autism: A Systematic Replication

Description: The purpose of this study is to investigate the effectiveness of a treatment package to teach a child with autism to willingly accept skin care products conducive to health and normal everyday living. The current study uses graduated exposure, modeling and contingent social attention to teach the child to accept the application of skin care products previously avoided. Results of the study showed that the participant tolerated criterion amounts of all target stimuli with both experimenter and … more

Effects of a Remote-Controlled Tactile Prompt on the Initiation Skills of a Child with Autism

Description: A 4-year old child with autism was taught to make a social initiation statement following a remote-controlled tactile prompt (RCT). The RCT prompt was taught by using a time-delay procedure with written script cards containing initiation statements. Training trials occurred in 6 different play locations in the child's room. Restricted Trial training consisted of allowing the child to play independently, activating the RCT prompt and playing with the child based on any initiation until a warning… more

Programming Common Stimuli to Promote Generalized Question-Asking in a Child with Autism

Description: A 5-year-old child with autism was taught to: (a) ask "What is that?" in the presence of unknown objects and (b) name the objects he did know. Generalization in the presence of the experimenter was probed across four new tasks. The child's performance generalized to the first 3 tasks without additional training. The fourth task required programming of common stimuli before generalization occurred.

An experimental analysis of opportunity and communication response form in a child with autism and hearing impairments.

Description: An alternating treatment design was used to systematically evaluate the communication response forms, picture exchange communication system (PECS) or sign language, selection for a child with pervasive developmental disorder-not otherwise specified, profound hearing loss, and cochlear implants. The child had a limited pool of high preference items and very few functional skills. Key factors for this child included a structured environment that created a verbal community and contingent access to… more
