We aimed to identify unique constellations of sensory phenotypes for genetic etiologies associated with diagnoses of autism spectrum disorder (ASD) and intellectual disability (ID). Caregivers reported on sensory behaviors via the Sensory Profile for 290 participants (younger than 25 years of age) with ASD and/or ID diagnoses, of which…

Research has supported the existence of distinct behavioral patterns, demographic correlates, and etiologic mechanisms for aggressive (AGG) versus nonaggressive but delinquent (DEL) antisocial behavior. Though behavioral genetic studies have the potential to further crystallize these dimensions, inconsistent results have limited their…

Contends treatment strategies often are premised on modifying either environmental factors or clients' interpretations of the interpersonal environment, but a more complete analysis would take into account the role played by genetic transmission in an individual's personality. Recommends when developing interventions both counselors and clients…

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…

The Lesch-Nyhan syndrome (which only affects males) is a heritable disorder of the metabolism of uric acid in which behavioral manifestations are prominent and among the most provocative. (Author/SBH)

This article examines the clinical aspects of etiology-related behaviors in young children with genetic mental retardation syndromes. Discussion of the concept of behavioral phenotype leads to consideration of how interventionists can best provide more focused and more effective interventions for children with different genetic disorders and…

Hyperactivity refers to a constellation of symptoms, any combination of which may be present in a given child, and also to a variety of factors, such as: impulsiveness, distractability, irritability, explosiveness, immaturity, underachievement (despite normal intelligence), and visual-motor dysfunction. Preventive measures must take into account…

Although descriptive and etiological approaches to psychopathology have made notable advances, they seem to have reached a plateau. After reviewing the six approaches to etiology that now preempt the field--ecological, developmental, learning, genetic, internal environment, and neurophysiological models--a second-order model, vulnerability, is…

This article examines the status of behavioral research on genetic mental retardation syndromes and finds that the field continues to struggle with three methodological issues: (1) how to think about control or contrast groups, (2) the interplay of behavioral phenotypes with development and other within-group variations, and (3) the efficacy of…

The annotated bibliography of over 1,200 citations published between 1943 and 1983 is intended as a comprehensive reference guide to the scientific study of infantile autism. After a search of the literature was conducted, the information was organized by format and subject, first for journal articles (19 topics are concerned with general…

The proceedings include 33 papers and two addresses on the psychopathology of mental development. The following six subject areas are considered: genetics and neurophysiology, socio-cultural and paranatal factors; epidemiology; behavior characteristics and learning; observational techniques and measurement of intelligence; and diagnosis and…
