Discusses studies by Donald LaSalle showing that students' performance can vary widely over the day according to the workings of their individual biological clocks. Presents exercises to help children identify their own "body rhythm prime time" and suggests rescheduling instruction to accommodate these differences. Condensed from…

Compares ontogenetic models, which stress development through a series of stages; sociogenic models, which stress the influence of social context on adult behavior; and liberative models. Liberative models do not treat adult development as entirely dependent on biological or social determinism, and do stress individuals' conscious efforts at…

The links between endocrine physiological processes and adolescent psychological processes are the focus of this article. Presents a brief history of biopsychosocial research in adolescent development. Discusses four models for conceptualizing hormone-behavior research as illustrative of biopsychosocial models. Concludes with challenges and…

Related blood levels of testosterone and sex hormone-binding globulin in pregnant women to gender role behavior among 342 male and 337 female offspring at 3.5 years. Found that testosterone levels related linearly to girls' gender role behavior. Neither hormone related to boys' gender role behavior. Other factors, including older brothers or…

Presents a theoretical model that attempts to account for the early stages of language acquisition in terms of interaction between biological constraints and input characteristics. Notes that the model uses the implications of stochastic representations of the sensory input in a volatile and limited memory. Argues that phonological structure is a…

Discusses the environmental and constitutional factors of learning and behavioral problems in school children, and suggests an approach for management. Proposes an expanded role for the medical practitioner in assessment and management. (RJC)

The article reports research supporting a view which sees learning disabilities as resulting from the interplay between a poorly elaborated knowledge base (especially in language related domains), the biologically determined efficiencies of such processes as encoding, and the physical and social meaning attached to performance (i.e. the context).…

In response to Coles (EC 220 146), the article examines evidence of the roles of intrinsic biological characteristics and the environment in learning disability and suggests that learning disability is a biological susceptibility manifested in an environment promoting its expression. (DB)

Describes Fetal Alcohol Effects (FAE) and Fetal Alcohol Syndrome (FAS) in infants, caused by mothers' consumption of alcohol during pregnancy. Both disabilities found in relatively high proportions of American Indian children. Discusses impact of disabilities on education. Discusses parent education programs in United States and abroad. (TES)

Reviews recent research in universal grammar-based child second language acquisition (SLA) research, arguing that child SLA studies can better explore the role of biological factors in language acquisition and strengthen the links between SLA and linguistic theory. (129 references) (MDM)

This paper presents two case studies of children who developed herpes virus infection in the intrauterine or early postnatal period and presented with features of autism around two years of age. Other research suggesting a link between herpes and autism is reviewed. (DB)

This paper summarizes empirical findings of research on a theory of general mental ability, based on laboratory studies of the relationship between measurements of individual differences on conventional psychometric tests and in speed and efficiency of information processes. The paper covers characteristics of "g" (general mental ability),…

Explores the claim that successful second-language acquisition (SLA) is the result of social, psychological, and affective factors; the argument that this claim has been falsified is untenable. Exploration of behavioral, psychological, and biological constructs to generate new formulations is a more productive approach to SLA theory building than…

Presents information from neuroscience which suggests that intelligence has a biological basis and may be physiologically identifiable in the future, noting that the critical time frame for intervening with gifted children may be even earlier than age 1-3 years, and adjustments may be needed to accommodate the precocious developmental time line…
