Research on spatial navigation is essential to understanding how mobile species adapt to their environments. Such research increasingly uses virtual environments (VEs) because, although VE has drawbacks, it allows for standardization of procedures, precision in measuring behaviors, ease in introducing variation, and cross-investigator…

Certain concepts that are sometimes confused in discussions on testing socially disadvantaged children are clarified and a history of testing, beginning with Binet, is presented. Finally, five problems in using tests to evaluate educational programs for the disadvantaged are considered. (AG)

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…

Five elementary school groups, or cohorts, were given the Test Anxiety Scale for Children and the Lie Scale for Children on three occasions over a year's time. This paper examines the results cross-sectionally and reveals between-group, or cohort effects. The youngest and oldest cohorts displayed low anxiety. Within-group longitudinal changes did…

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…

The sequence of development as hypothesized by Piaget has been confirmed for various groups of children by cross-sectional and longitudinal studies. Such consistency has increased interest in constructing scales based on Piaget's theory according to psychometric principles. Three major problems are discussed which present definite obstacles in the…

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…

Traditional developmental protocols based on neurological or sensorimotor models frequently underestimate the cognitive status of physically handicapped infants. A critical review of current clinical practices in the area of infant assessment is followed by a discussion of an alternative approach, a perceptual-cognitive approach, and the…

Questionnaire results from l04 psychologists serving the blind and partially sighted indicated disagreement on the tests used and on the evaluation of these tests. Tests of all kinds from 45 publishers were rated, and appropriate ages and populations (blind, partially-sighted) were suggested. (CP)

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…

Article examined the validity of some of Piaget's and Bruner's findings in non-western cultures, the relationship between cognitive models that they developed, and the implications for curriculum, teaching and learning of any data newly discovered. (Author/RK)

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)

Support claims that the "Defining Issues Test" of cognitive-moral development cannot be faked higher. Finds that instruction about cognitive-moral development affected the scores of the teacher trainees who were tested. (RL)

Discrepancies between the mental age (MA) scores and the mean performance of chronological age (CA) groups in the latest revision of the Stanford-Binet Intelligence Scale are noted. A table is presented for converting published Stanford-Binet MA scores into MA scores that are congruent with the above definition. (Author)

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…
