Executive function (EF) skills are the attention-regulation skills that make it possible to sustain attention, keep goals and information in mind, refrain from responding immediately, resist distraction, tolerate frustration, consider the consequences of different behaviors, reflect on past experiences, and plan for the future. As EF research…

Testing of the similar structure hypothesis (which states that when matched for level of cognitive development, mentally retarded and nonretarded individuals do not differ in cognitive processes) with 40 mentally retarded adults and nonretarded mental age peers on Piagetian tasks found the developmental theory favored 4:1 over the difference…

Post-formal operational thought is characterized by both relativism and dialecticism. To examine age differences across adulthood in relativistic and dialectical thought, and to determine whether formal operations are necessary but not sufficient for these forms of thought, 20 young (mean age, 19.6), 20 middle aged (mean age, 46.2), and 20 older…

Research findings suggest the existence of three types of primitive regulation in the behavior of 1 1/2- to 2 1/2-year old children in memory tasks. When children are presented with a game of hide-and-seek to be played with a small stuffed animal, regulatory behavior appears to be related to children's use of stimulus information, precursors of…

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…

Argues that Susan Sugarman's article in this issue contains some valid criticism of assumptions in developmental psychology, but that some of her conclusions regarding other assumptions need to be questioned. Suggests that many problems raised by Sugarman would disappear if developmental psychologists concentrated on children's early achievements…

Evaluates some possible reasons for the occurrence and eventual correction of children's naming errors in an experiment in which two-, four-, and six-year-olds learned two artificial object names in succession. (HOD)

Inhelder and Piaget found that somewhere between 12 and 15 years of age, children's thinking shifted from concrete to formal operations. To determine if this shift occurs at approximately the same age for learning disabled children (N=27) compared to normal learning children (N=27) was the task of the study reported. (JN)

Because visual short-term memory deficits are common in children with reading problems, a series of experiments were reviewed which examined the role of phonological processes in short-term memory. Results suggest that both developmental and individual differences in verbal memory span are related to efficient phonological processes. (Author/DB)

Discusses issues related to the adoption revelation process and the two interrelated goals of telling and understanding. Evidence indicates developmental changes in the way children understand this family status. Distinction between "working adoption vocabulary" and true understanding of adoption is made. Provides guidelines concerning…

The paper notes A. Hore and W. Tryon's support of the developmental position that persons with and without mental retardation of similar mental age show similar cognitive patterns, but suggests that mental age is psychometrically invalid and Piagetian tasks are inappropriate to evaluate this position. An information processing approach is…

Myth is integral to modern as well as ancient societies in its service to multiple interrelated social functions. Among these are to explain phenomena and direct action, to justify particular interests or practices, to dramatize ideals, and to provide cultural cohesion. Three prevailing myths that are especially problematic are the myths of…

Examples of explanations students give during science lessons are used to demonstrate that there are a number of very different modes of explaining. In addition, it is suggested that the peculiarly scientific method of explanation is fraught with difficulties, some of which current learning theories may just be able to describe. Areas discussed…

Argues that there are significant ways in which neither Piaget nor his successors in developmental psychology have adequately described the child's mind and how it changes. Proposes alternative guidelines for research that aims more directly at identifying essential constituent features of the child's mental reality. (PCB)

Examines research in developmental psychology and science education that has attempted to assess the validity of Piaget's theory of formal thought and its relation to educational practice. Position papers (with little or no empirical support) are not included. (Author/JN)
