Developmental, learning, and behavioral disabilities are a significant public health problem. Environmental chemicals can interfere with brain development during critical periods, thereby impacting sensory, motor, and cognitive function. Because regulation in the United States is based on limited testing protocols and essentially requires proof of…

Background: This project examined the intermodal perception of temporal synchrony in 16 young children (ages 4 to 6 years) with autism compared to a group of children without impairments matched on adaptive age, and a group of children with other developmental disabilities matched on chronological and adaptive age. Method: A preferential looking…

Structured checklists have been used to supplement psychiatric assessment of children with normal intelligence, but for children with intellectual disability, only a few checklists exist. We evaluated the Child Behavior Checklist (CBCL) in the assessment of psychopathology in Finnish children with intellectual disability. The CBCL was completed by…

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…

A retrospective study was conducted in a clinic specialized in treating individuals with developmental disabilities to examine the effectiveness and tolerability of quetiapine in children and adolescents with pervasive developmental disorders. Ten consecutive outpatients (age = 12.0 [plus or minus] 5.1 years) treated with quetiapine (dose = 477…

The present study aims to assess the parental outcomes of an early intervention programme, designed to enhance the development of children zero to four years old with developmental disabilities through parental training. The parents of children with developmental disabilities who participated in the study (mothers, n = 29; fathers, n = 28)…

This investigation examined the effectiveness of a computer program in teaching sight word recognition to four young children with developmental disabilities. The intervention program was developed through a formative evaluation process. It embedded a constant-time-delay procedure and involved sounds, video, text, and animations. Dependent…

Background: Few previous studies have examined Antonovsky's (1979, 1987) "sense of coherence" (SOC) in parents of young children with developmental disability (DD). This study explored relationships between parental stress, SOC, social support, and health in parents of preschool children with and without DD. A secondary aim was to explore the…

Background: The superiority of language and communication skills in children and adults with Williams syndrome (WS) is currently being debated. Whilst there have been a number of reports of precursors of language in WS in children who have already developed language, there have not been many studies that have prospectively investigated precursors…

We tested the effects of multiple exemplar instruction (MEI) on the emergence of untaught mands or tacts of adjective-object pairs in a multiple-probe design across four students with autism/developmental disabilities. None of the students emitted either mands or tacts for three sets of three adjective-object pairs (word sets counterbalanced…

Functional communication training (FCT) is an intervention frequently used for students with developmental disabilities to reduce problematic behaviors and to increase prosocial behaviors. This intervention appears to be very effective when the communication responses trained are matched to the function of the student's problematic behaviors. In…

A multiple probe study across behaviors, replicated across students, assessed the effectiveness of simultaneous prompting (SP) in a small group teaching arrangement on teaching (a) to show the provinces, rivers, and border countries of Turkey on a map and (b) to expressively identify the names of the symbols which are usually used in math.…

Growing evidence suggests that self-determination is a significant factor in improving educational and transition outcomes in students with intellectual and developmental disabilities. This volume reviews the breadth of available methods for teaching components of self-determination--including choice making, problem solving, decision making, goal…

Prader-Willi syndrome (PWS) is a genetic disorder which has widespread developmental consequences including motor, cognitive and language delay. Previous research on PWS children has focused primarily on phonological development and dysfluency. In the present study, the lexical development of a boy with PWS was investigated in a series of 18 play…

In school settings, students are typically evaluated using group achievement tests, IQ scales, and college entrance exams that focus more on rote-verbal skills (e.g., vocabulary, mathematical facts) than on higher level executive functions (e.g., abstract thinking, problem solving). However, recent neuropsychological findings suggest that…
