Formulates further propositions towards a comprehensive structural developmental theory of cognitive change with focus on: a) organization of subject's assimilatory operations and accomodatory figurations; b) intrinsic coordinations between the theoretical and empirical cognitions constructed, respectively, by these two kinds of functional…

A study proposing reality and fantasy discrimination of television content as a classificatory ability sought to identify differences between subjects who were able to make sophisticated reality-fantasy judgements and those who were not, and factors which might contribute to a subject's sophistication in discrimination. Open-ended and structured…

This review of the current state of research on how children make sense of television and its content examines age-related differences in children's interpretations of television entertainment content in general, and advertising content in particular. A brief analysis and description of the fundamental principles of cognitive development theory…

Conservation of a property is the ability to recognize that the property in question hasn't altered, even though other properties have been varied. It is Piaget's view, confirmed by empirical evidence that children are not able to conserve length until age 7 or 8. Recent concern over confounding variables led to the present study in which the…

Forty infants, 10 at 4, 6, 8, and 10 months, were confronted by an experimenter who acted out angry, happy, sad, and neutral facial experssions, accompanied with appropriate vocalizations. The infants' responses were recorded on video tape and rated for attention, negative and positive affect, and activity. Results indicate that the 4-month old…

This study sought to determine whether a number of specific counting and numeration behaviors emerge within children in a fixed developmental sequence; at what point in the development of mathematical behavior the use of numerical representations normally appears; and what relationship holds between development of counting skills and development…

Borrowing freely from Freud, Piaget, and others, this article compares and integrates primary (emotional) and secondary (intellectual) process according to seven distinct but overlapping structures: (1) weight; (2) pathways; (3) time and space; (4) operational dialectic; (5) sources of energy; (6) morality; and (7) historical antecedents. Primary…

There are numerous and complex events taking place during brain maturation that provide the biologic underpinnings of learning and behavior. (MM)

Discusses the possibility of a neurolinguistic interconnection between the parieto-temporo-occipital junction, semantic aphasis, and cognitive and language development around age seven. (Author/HP)

Although most males with a 49,XXXXY karyotype will have significant mental retardation, the case of an affected boy having mild-cognitive and motor delays and age-appropriate adaptive skills at 59 months is presented. Guarded optimism may be justified in affected males demonstrating close to or age-appropriate developmental skills through early…

Issues and developmental considerations in outcome and treatment of head injury in children are considered. Focus is on appropriate assessment practices in the areas of psychoeducational development, motor and cognitive deficits, and neuropsychological deficits. (Author/DB)

Investigates whether 6- to 12-month-old infants' exposure to the successful search behavior of a sibling in two object-concept tasks would enhance infants' subsequent performance on these tasks. (HOD)

This study that examined the economic reasoning of preschool and elementary school children concluded that (1) the nature of children's economic reasoning is supportive of cognitive development theory; (2) children's economic reasoning varies somewhat by personal experiences, and (3) the intermediate grades are an appropriate level to emphasize…

Describes a study designed to compare color-name with shape-name learning by three-year-old children in an experimentally controlled format. Results show that children learned color-label associates significantly more slowly than matched shape-label associates, and they committed more errors with colors than with shapes during learning. Provides a…

The relationship of maternal behavioral style to cognitive development states of 60, 1-, 2-, and 3-year-old organically impaired, mentally retarded children was investigated. Factor analysis of maternal behavioral items revealed three major parameters of behavior. Child-Oriented/Maternal Pleasure was related positively, whereas Quantity of…
