Tests the developmental lag hypothesis, which assumes that a surface pattern of reading difficulties should be attributed to a general developmental delay. Compares a sample of very low birth weight children with a group of same-age, normal readers. Provides further evidence that a surface pattern of reading difficulty should be attributed to a…

Five elementary students with developmental disabilities were taught health and safety facts using either classwide peer tutoring (CWPT) or traditional teaching methods. Comparison indicated that both CWPT procedures and traditional teacher-led procedures produced similar outcomes. Discussion focuses on advantages of using CWPT to acquire basic…

Tangible and pictorial paired-stimulus (PPS) preference assessments were compared for 6 individuals with developmental disabilities. During tangible and PPS assessments, two edible items or photographs were presented on each trial, respectively, and approach responses were recorded. Both assessments yielded similar preference hierarchies for 3…

The aim of this article is to provide an in-depth description of early development in a young child with Smith-Magenis syndrome (SMS). SMS is a multisystem, neurodevelopmental genetic disorder associated with mental retardation that predisposes individuals to a distinct pattern of maladaptive behaviors and other neuropsychological impairments.…

This article describes the ASSETS School, a K-12 school for gifted, dyslexic, and gifted-dyslexic children in Honolulu, Hawaii. Originally founded as a school that provided specialized education for developmentally disabled children of military families stationed in Hawaii, in the mid 70s, ASSETS rededicated its mission to become a haven for…

Three children with developmental disabilities were taught to initiate social interactions to typically developing peers using scripts (Krantz & McClannahan, 1993). Scripts were statements written on a page or recorded onto audio cards that were repeated by the participants. A multiple-baseline-across-participants experimental design was used to…

Four adults with developmental disabilities were taught to make conditional discriminations between either pictures and their corresponding printed English and Spanish words, or tastes and their corresponding printed English and Spanish words. Participants required more training trials to master the visual-visual conditional discriminations than…

Feeding and mealtime behavior problems are commonly observed among individuals with developmental disabilities. These problems include, but are not limited to, food refusal, food selectivity, mealtime aggression, rumination, pica, and insufficient feeding skills. Difficulties of this type can be associated with life-threatening consequences of…

The human and mouse genome projects elucidated the sequence and position map of innumerous genes expressed in the central nervous system (CNS), advancing our ability to manipulate these sequences and create models to investigate regulation of gene expression and function. In this article, we reviewed gene targeting methodologies with emphasis on…

The instructional scheduling arrangements of simulated and community-based instruction across an equivalent set of functional and vocational skills were examined. Five secondary age students with moderate intellectual disabilities participated in four instructional scheduling arrangements measuring skill acquisition, generalization, and…

Students with developmental disabilities often rely on prelinguistic behavior (e.g., reaching, leading) to communicate. When listeners fail to attend to prelinguistic behaviors, students may benefit from responding with an alternative form of communication to repair the breakdown. In the present study, we taught two students with developmental…

This paper reviews a body of prominent theories of automaticity in developmental dyslexia. The first part of the review considers the relationship between dyslexia and rapid automatic naming and fluency. Additional theoretical and empirical advances are suggested to this already strong research base. In particular, there is a need is for…

Programmed Instruction combined with experimenter-provided prompts (physical, verbal, and gesturing) was used to teach pointing with a computer mouse. Three preschoolers who scored at least 1 year below their chronological age levels participated. During the pre-assessment, none of the participants demonstrated pointing. However, they could press…

The level of IgA antibodies to gluten and gliadin proteins found in grains and to casein found in milk, as well as the level of IgG to gluten and gliadin, have been examined in 23 girls with Rett syndrome and 53 controls. Highly statistically significant increases were found for the Rett population compared to the controls. The reason for this…

This article presents a critical analysis of the principle of the least restrictive environment (LRE). The article begins with a review of the origins of LRE in professional writings and law and moves next to a discussion of how LRE has been operationalized in terms of a continuum of residential, educational, and vocational services. Building on…
