The theory and purpose underlying R. Feuerstein's Learning Potential Assessment Device (LPAD) is reviewed, and implications for deaf education considered. It is argued that LPAD use will enhance: (1) assessment of deaf children from non-standard American backgrounds; (2) incorporation of assessment results into educational programming; and (3) the…

Research on Piaget's four stages of cognitive development has shown that although nearly everyone passes through sensorimotor, preoperational, and concrete operational stages, most do not reach the stage of formal operations. Those people who do attain formal operations seem to have a curiosity factor not operative in those who don't. (Author/BRR)

This paper discusses the impact of emerging developmental skills on preschoolers' test performance in reference to preoperational thinking, behavioral controls, and language skills. It is emphasized that some behaviors that occur during the preschool period may suggest pathology when observed in older children but are normal for preschoolers. A…

Examines several possible difficulties in interpreting the results of studies which employ Piagetian tasks, especially conservation tasks, with older individuals. Notes that Piaget's clinical method allows more flexibility in the assessment of competence than do more quantifiable techniques. Examines the possibility of task misinterpretation by…

Criticizes the Mitchell and Lawson (1988) report from the viewpoint of individual interview method. Provides Lawson's reply to the comment by showing differences in research philosophy and methods. (YP)

Piagetian research provides the focus of this article in which Professor Thomas C. O'Brien interviews Professor Hermina Sinclair. Aspects of children's thinking that prefigure scientific theory construction are described and the influence of schooling in inhibiting or suppressing a theory-building human tendency is briefly discussed. The…

Despite its failings, Herrnstein and Murray's "The Bell Curve" is valuable for emphasizing cognition as significantly affecting human performance and social achievement; acknowledging human differences; and offering a frightening depiction of contemporary American society. The authors err in reducing intelligence to a stable, immutable…

Age-related changes in representational flexibility are a characteristic feature of declarative memory development. The authors suggest that a qualitative shift in the nature of infants' memory representations accounts for increasing memory flexibility with age. We will argue that a comprehensive theory of declarative memory development must (1)…

The paper reviews contributions of J. Piaget and others to the understanding of perception's importance in the cognitive development of mentally retarded children. The effects of poor discrimination learning on IQ scores are noted. (CL)

This paper presents the thesis that a perceptual rationale for visual literacy may be found in operational form within what is measured by established tests of cognitive style. Ten primary dimensions of cognitive style are briefly reviewed, including field independence-field dependence, impulsivity-reflectivity, visual-haptic, leveling-sharpening,…

Analysis of effects of different starting points on the Bayley Scales of Infant Development II Mental Scale found that starting at the child's chronological age consistently inflated scores, whereas starting at the lowest item set skewed results in the opposite direction. Testing downward until all items are passed and upward until all items are…

Attention is drawn to the ways in which current conceptions of intelligence and its measurement differ from those which were generally accepted in 1928. The following principles underlying intelligence testing were generally agreed upon in 1928: (1) the assumption of intelligence as a recognizable attribute, responsible for differences among…

Presents the rationale for and the results of a pilot study attempting to document in detail how automatization takes place as the result of different kinds of intensive practice. Results show that reaction times and error rates gradually decline with practice, and the practice effect is skill-specific. (36 references) (CK)

Basic principles of instruction to effect cognitive change are examined, particularly within the context of South African higher education. Principles include: creating and engaging in conflict between existing knowledge and demands of an unfamiliar task; empowering learners to address the unfamiliar; scaffolding between learner and task; testing…

Argues that Herrnstein and Murray's "The Bell Curve" (1994) merely restates the notion that intelligence can be reduced to a single ordinal measure, i.e., the primary factor for determining group or individual social-class status. Evidence from the biological sciences and quantitative genetics is presented that reveals that social…
