Discusses how McGraw's work broached the notion of a reciprocal relationship between structural maturation and function, thus anticipating the current understanding of the role of experience in the cortical and motor maturation of infants in the first year of postnatal life. Also presents her clear formulation of a flexible critical period concept…

Reexamines McGraw's research and theoretical principles on early neuromotor development, focusing on unaided walking. Notes that contemporary research supports and clarifies her observations providing greater detail about factors involved in the formation of higher-order control, and amplifying the role of experience. Discusses possible mechanisms…

Maintains that McGraw conducted a more complex analysis of neurobehavior than acknowledged by those characterizing her position as maturationist; that she advanced a unique analysis of brain development and consciousness, singling out the reciprocal relationship between neural growth processes and early experience; and that her studies of the role…

Implications of three basic facts about very young infants are delineated in this summary. Normally, human infants are capable of a wide range of functions, such as "appetitive responses" (e.g., the rooting reflex) and defensive maneuvers. They experience pleasure and feel pain. Additionally, they undergo a transition from subcortical to…

This abstract bibliography cites recent ERIC documents and journal articles concerning the differentiated functioning of the brain hemispheres. Entries include resumes from Resources in Education (RIE), October 1973 through December 1977, and citations from Current Index to Journals in Education (CIJE), November 1974 through December 1977.…

This paper presents autoassociator neural networks. A first section reviews the architecture of these models, common learning rules, and presents sample simulations to illustrate their abilities. In a second section, the ability of these models to account for learning phenomena such as habituation is reviewed. The contribution of these networks to…

A growing body of scientific evidence demonstrates that emotional development begins early in life and is closely connected with the emergence of cognitive, language and social skills. Early emotional development lays the foundation for later academic performance, mental health, and the capacity to form successful relationships. Despite this…

The stress response systems of the human child are highly sensitive to social challenges. Because stress hormones can have negative developmental and health consequences, this presents an evolutionary paradox: Why would natural selection have favored mechanisms that elevate stress hormone levels in response to psychosocial stimuli? Two…

This paper reviewed research that sheds light on the relation between motor and ideational learning and suggested a cognitively oriented role for physical education in the early years. (Author/RK)

This address examines the future of biobehavioral science and the opportunities and pitfalls it holds for individuals with intellectual and developmental disabilities. Examples of recent advances in genetics and neurosciences are discussed, as well as opportunities that these advances hold for understanding the effects of the environment on…

Examines the weak relationship between structural and functional brain development. Maintains that variability is the basic characteristic of normal development, and that involves the ability to construct pluriform strategies and to select the proper strategy in any particular situation. Argues that McGraw recognized intra- and inter-individual…

A discussion of the biological and developmental issues in early second language learning first looks at psycholinguistic research on brain growth patterns and the relationship of first and second language learning. Focus is on three phenomena observed in the self-organization of living systems: selection of input data; organization of specialized…

Studies on human patients and animal models of disease have shown that disruptions in prenatal and early postnatal brain development are a root cause of mental retardation. Since proper brain development is achieved by a strict spatiotemporal control of neurogenesis, cell migration, and patterning of synapses, abnormalities in one or more of these…

It has long been recognized that from the first months of life auditory perception plays a crucial role in speech and language development. Only in recent years, however, is the precise mechanism of auditory development and its interaction with the acquisition of speech and language beginning to be systematically revealed. This paper presents the…
