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.…

This investigation compared the use of static picture prompting, in a cookbook format, and video prompting to self-prompt four students with moderate intellectual disabilities to independently complete multi-step cooking tasks. An adapted alternating treatments design (AATD) with baseline, alternating treatments, and final treatment condition, was…

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…

The use of a handheld prompting system by four students with moderate to severe intellectual disabilities to independently transition between an ordered chain of tasks was examined in a community vocational setting. Effectiveness of the handheld prompting system was assessed using a multiple-probe design across participants. Analysis of the data…

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…

Effectiveness of a simultaneous prompting procedure was evaluated for students with mental retardation at different levels of schools (preschool, primary and secondary grades) using various discrete tasks. Participants included three students whose functioning levels ranged from typically developing to mild and moderate mental disabilities.…

In this study, kindergarten children's scores on nine cognitive tasks were evaluated as potential predictors of poor achievement in first grade. A set of five tasks successfully identified 83% of children who were poor readers in first grade, while just three tasks identified 72% of children who were poor achievers in math in first grade. There…

Effects of a constant time delay procedure on aquatic play skills of children with autism was investigated. A single subject multiple probe model across behaviors with probe conditions was used. Participants were four boys, 7-9 years old. Data were collected over a 10-week period using the single opportunity method as an intervention. Results…

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…

In this study, predictive classification accuracy was used to select those tasks from a kindergarten screening battery that best identified children who, three years later, were classified as educable mentally handicapped or as having a specific learning disability. A subset of measures enabled correct classification of 91% of the children in…
