Minicolumnar changes that generalize throughout a significant portion of the cortex have macroscopic structural correlates that may be visualized with modern structural neuroimaging techniques. In magnetic resonance images (MRIs) of fourteen autistic patients and 28 controls, the present study found macroscopic morphological correlates to recent…

Part Two of the article focuses on the development of manual motor skills in learning disabled children. After a discussion of test methods, the author considers aspects of a medical examination, including a general exam, a neurological exam, an electroencephalogram, and a diagnostic test of hand/motor skill development. (For Part One, see EC 123…

Discusses the vestibulo-ocular reflex (VOR) which is used to investigate the neural basis for motor learning in monkeys. Suggests organizing principles that may apply in forms of motor learning as a result of similarities among VOR and other motor systems. (Author/RT)

Introduces this special journal issue re-examining the contributions of Myrtle McGraw to developmental psychology in order to clarify misinterpretations of her work and to highlight dimensions that constitute promising lines of inquiry for contemporary researchers. Maintains that McGraw failed to receive credit for her alternative to…

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…

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…

This booklet presents educational programs and activities focusing on motor skills for 5- to 9-year-old children and older children with learning problems. The premise of the activities is that the acquisition of motor skills is essential to basic learning. The role of language as a mediator and controller of motor development is emphasized. The…
