Aim: The present study investigated the effects of varying the cognitive demands of a memory task (a suprapostural task) while recording postural motion on two groups of children, one diagnosed with developmental coordination disorder (DCD) and an age-matched group of typically developing children. Method: Two groups, each comprising 38 child…

We assessed the relationship between brain structure and function in 10 individuals with specific language impairment (SLI), compared to six unaffected siblings, and 16 unrelated control participants with typical language. Voxel-based morphometry indicated that grey matter in the SLI group, relative to controls, was increased in the left inferior…

The Assessment of Basic Learning Abilities (ABLA) is a tabletop-based protocol employing manipulables that is used to gauge whether individuals with severe developmental disabilities can learn to perform a series of discrimination tasks of varying levels of difficulty. Empirical research suggests that the ABLA is useful in terms of predicting…

The Assessment of Basic Learning Abilities (ABLA) test is a useful assessment and training tool for persons with developmental disabilities. The present study assessed the predictive validity of the ABLA test with 16 children diagnosed with an autistic spectrum disorder, eight who performed at ABLA Level 4 and eight who performed at ABLA Level 6.…

We reviewed twelve studies that used the constant time delay (CTD) procedure to teach chained tasks to individuals with developmental disabilities from years 1996-2006. Variables analyzed include types of tasks that have been taught with the procedure, how effective CTD has been in teaching participants, and whether researchers have investigated…

Video prompting is a training procedure used to teach a complex behavior by showing steps of a task analysis on video. The present study evaluated how many steps in the video model were required for the learner to acquire a 10 step laundry task. Participants were three individuals with mental retardation. Participants viewed the entire task on…

This study examined Theory of Mind in Williams syndrome (WS) and in normal chronological age-matched and mental age-matched control groups, using a picture sequencing task. This task assesses understanding of pretence, intention and false belief, while controlling for social-script knowledge and physical cause-and-effect reasoning. The task was…

We evaluated a video-based error correction procedure for teaching four adults with developmental disabilities to set a table. Video clips were initially used as an antecedent prompt. However, only one of the adults learned to set the table with this procedure. Consequently, the remaining three adults received intervention in which the video clips…

The present study was designed to determine whether parents (three mothers and one grandmother) could implement CBI with SP reliably for teaching community skills to their children and the effects of parent-delivered intervention on teaching the community skills. Maintenance and generalization effects of the intervention were also analyzed in the…

We evaluated a video prompting and fading procedure for teaching three adults with developmental disabilities to wash dishes. Video prompting involved showing video clips depicting each step of the task. All three adults reached 90-100% correct when video prompting was implemented. Following acquisition, video prompting was withdrawn, but…

A multiple probe across subjects design was used to evaluate the effectiveness of embedded instruction with three students with developmental disabilities who were enrolled in general education classrooms. Two general education teachers delivered embedded instruction to students during regularly schedule instructional activities. The skills taught…

We evaluated the use of a video prompting procedure for teaching three adults with developmental disabilities to make popcorn using a microwave oven. Training, using a 10-step task analysis, was conducted in the kitchen of the participant's vocational training program. During baseline, participants were instructed to make popcorn, but were given…

Profiles of verbal learning and memory performance were compared for typically developing children and for four developmental disorders characterized by different patterns of language functioning: specific language impairment, early focal brain damage, Williams Syndrome, and Down Syndrome. A list-learning task was used that allowed a detailed…

The report summarizes a 2-year project to train personnel in California agencies, facilities, schools and state hospitals in the principles of Try Another Way, a normalization-geared approach using systematic task analysis to teach moderately to profoundly retarded and severely developmentally disabled persons. The report's first three sections…

We compared two procedures (video prompting versus video modeling) for teaching six adults with developmental disabilities to set a table and put away groceries. Video prompting involved 10 separate video clips, each showing one step of the task analysis. Video modeling involved a single video showing all 10 steps from beginning to end. After…
