Dyslexia is one of the most studied learning disorders. Despite this, its biological basis and main causes are still not fully understood. Electroencephalography (EEG) could be a powerful tool in identifying the underlying mechanisms, but knowledge of the EEG correlates of developmental dyslexia (DD) remains elusive. We aimed to systematically…

Few published studies have systematically compared the efficacy of different prompt-fading methods in the training of complex response chains. The current study systematically compared a most-to-least physical prompt fading hierarchy with a most-to-least vocal prompt fading strategy in the training of four arbitrary Tinkertoy® construction tasks…

We conducted a systematic replication of Cannella-Malone et al. by comparing the effects of video prompting to video modeling for teaching seven students with severe disabilities to do laundry and wash dishes. The video prompting and video modeling procedures were counterbalanced across tasks and participants and compared in an alternating…

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…

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…

Background: The executive functions of inhibition, planning, flexible shifting of actions, and working memory are commonly reported to be impaired in neurodevelopmental disorders. Method: We compared these abilities in children (8?12 years) with high functioning autism (HFA, n = 17), attention deficit-hyperactivity disorder (ADHD, n = 21) and…

Purpose: This article reports a study in which referential communication in 11 individuals with Asperger syndrome (AS) and 11 controls was compared between text chat and telephone, using a route-solving task. Method: Participants deduced routes by asking closed questions, and the dependent variables were (a) accuracy in working out the route, (b)…
