A reaction to Sowell's book raises issues about behaviorally based diagnoses, stressing that developmental disorders are behaviorally defined dimensions along a continuum with no crisp partition between normalcy and disorders. It sees developmental disorders as usually the expression of extremely complex, multigenic influences on brain…

Interviews with 12 students with developmental disabilities, parents, and educators regarding the transition planning process found most students optimistic about the future, although parents and teachers thought transition planning was incomplete. Strategies to promote student involvement in transition planning were recommended. (JOW)

Discussion of family involvement in functional assessment (FA) with individuals who have autism or related disabilities first provides a rationale for family involvement, then reviews the literature and offers guidelines including: recognize, respect, and accommodate families' individuality; create a context for family centered participation; take…

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…

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…

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…

The First Year Inventory (FYI) is a parent questionnaire designed to assess behaviors in 12-month-olds that suggest risk for an eventual diagnosis of autism. We examined the construct validity of the FYI by comparing retrospective responses of parents of preschool children with autism spectrum disorders (ASD; n = 38), other developmental…

In a review of current research and the No Child Left Behind (NCLB) legislation, this paper focuses on two specific issues: (a) how students with developmental disabilities show adequate yearly progress, including a description of the assessments in which this population may participate, and (b) the policy issues surrounding NCLB including…
