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…

Sixty-four adults participated in a study examining the accuracy of metacognitive judgments during 28 hr of sleep deprivation (SD) and continuous cognitive work. Three tasks were studied (perceptual comparison, general knowledge, and mental addition), collectively spanning a range of cognitive abilities and levels of susceptibility to SD.…

The handbook describes a method of teaching communication skills to students with severe disabilities (severely and profoundly retarded, trainable mentally retarded, autistic, deaf blind, and severely multihandicapped). In the interrupted behavior chain procedure, a routinized activity in a natural setting is interrupted and the child is taught to…

To lay a foundation for the design and effective use of low-cost, part-task and low-fidelity training devices, this report identifies dimensions of skill performance in terms of modern learning and behavior theory, and analyzes cognitive and motor skills as they relate to information processing. Cognitive processes discussed include task…

The purpose of the study was to determine whether particular aspects of movement control influenced the performance of 2-year-old children on a standard developmental test, and thus influenced assessments of intellectual progress based on that test. Six cerebral-palsied (CP) children were compared with six children not suffering motor system…
