Eye tracking offers a powerful research tool for developmental scientists. In this brief article, the author introduces the methodology and issues associated with its applications in developmental research, beginning with an overview of eye movements and eye-tracking technologies, followed by examples of how it is used to study the developing mind…

Research into reading development and reading disabilities has been dominated by phonologically guided theories for several decades. In this volume, the authors of 11 chapters report on a wide array of current research topics, examining the scope, limits and implications of a phonological theory. The chapters are organized in four sections. The…

Brainstem auditory evoked potentials were compared in 109 children with infantile autism, 38 with autistic condition, 19 with mental retardation, and 20 normal children. Children with infantile autism or autistic condition had significantly longer brainstem transmission time than normal children suggesting neurological damage as the basis of…

The goals of this review are to: (1) provide a set of concepts to aid in the understanding of complex processes which occur during central nervous system (CNS) development; (2) illustrate how they contribute to our knowlege of adult brain anatomy; and (3) delineate how modifications of normal developmental processes may affect the structure and…

Maintains that Teyler and Fountain's presentation (1987) contains several limitations, namely, that the authors do not (1) distinguish between learning and memory, nor between storage and retrieval; (2) address the role of knowledge-based influences in memory and learning; or (3) employ concepts that can accommodate developmental phenomena in the…

Bi-articular, unidirectional arm movements were studied to evaluate the electromyographic (EMG) and neuromuscular force patterns that occur when a limb is unexpectedly perturbed. A series of training trials were continued with a control load spring attached to the apparatus until a pre-specified criterion for learning was attained. The limb was…

This commentary, written in response to Witelson's work (1987), examines alternative ways of determining how the developmentally stable functional asymmetry (hemispheric specialization) observed in neurologically intact children can be reconciled with the dramatic recovery of function often displayed following unilateral brain damage.

The goal of all speech rehabilitation methods is the restoration of speech as a unitary higher function. One approach views speech as a complex but coherent system where all levels and components are interconnected. This view takes into consideration the use of verbal communication, which takes place at a higher speech level and includes activity,…

The study assessed how unilateral right hemisphere brain damage (RHD) affects processing of metaphoric aspects of word meaning. RHD stroke patients (N=25) performed similarly to left-brain-damaged and normal subjects in the automatic condition and when provided with processing strategies. Both brain-damaged groups had difficulty developing…

Auditory brainstem responses (ABR) were measured in 535 children from 3 months to 3 years of age. Results suggested that changes in wave V latency with age are due to central (neural) factors and that age-appropriate norms should be used in evaluations of ABR latencies in children. (Author/DB)

Proster Theory is a theory of learning which has been proposed by Leslie A. Hart (1975). The theory is based on the functions of the brain. Learning is seen as the formation of programs, which are simply sequences of instructions by which the brain directs the muscles, sense organs, or other portions of the neurological system. Programs which are…

The role of experience in the developing brain is considered. A categorization scheme based upon the type of information stored and the brain mechanisms involved in storing the information is proposed. Experience-expectant and experience-dependent information storage are differentiated. (BN)

Data suggesting that different brain circuits may underlie different forms of learning and memory are reviewed. Several current theories of learning and memory with respect to hippocampal and other brain circuit involvement are considered. (PCB)

Recent studies on the biological development of the prefrontal cortex in rhesus monkeys are reviewed. These studies have elucidated the basic neural circuitry underlying the delayed-response function in adult nonhuman primates and suggest that a critical mass of cortical synapses is important for the emergence of this cognitive function.

Discusses the relevance of the study of the neurobiology of cognitive development, for an understanding of both the neural bases and the nature of cognition. Also considered are the age at which hemisphere specialization first appears and whether hemisphere specialization changes over time. (PCB)
