The possible effect of experimenter expectancy in number conservation task experiments was explored. (JMB)

Examined how college-age adults and 8-, 11-, and 13-year-olds retrieve semantic information from long-term memory. Closely comparable results were obtained across ages. This developmental similarity is discussed in relation to developmental differences in the use of semantic information in other cognitive tasks. (JMB)

Boys, ages 6, 8, and 10, were classified with regard to conceptual tempo and were presented with cartoon stimuli varying in cognitive complexity and level of affectivity. The results indicate that reflective subjects generally displayed the highest comprehension scores while impulsive subjects displayed the greatest spontaneous mirth. (JMB)

Two experiments investigated the role of kindergarten and elementary school children's spontaneous cognitive sets in pictorial discrimination learning. Data indicated that, in comparison to the behavior of older children, the behavior of kindergarteners is governed more by the perceptible than by the conceptual attributes of stimuli. (GO)

The present study investigated egocentricity in children and youth. Exner's Self-Focus Sentence Completion (SFSC) was used to measure egocentricity. (Author/RK)

Examined the effects of varying degrees of teacher support on middle-class preschoolers' success in cognitive and motor learning tasks. Support was defined in terms of physical proximity, physical contact, and facial and verbal behaviors. (JMB)

A necessary condition for studying cognitive images of environments is an appropriate method to define and measure these. Using a sample of students in Bristol, the Repertory Grid method was used to measure images of the retailing environment. The empirical results are discussed and possible future research is outlined.

The purpose of the present investigation was to examine the relationship between the stages of cognitive development proposed by L.S. Vygotsky and by J. Piaget. (Author)

By controlling heartbeat and other body functions at will, patients are curing a variety of illnesses. (Editor)

Described methods of meditation, how it can benefit mankind, and warned of fraudulent teachers. (RK)

College students were asked to reason about the relative speeds of horses turning on a merry-go-round platform. Results revealed that, unlike field independent subjects, field dependent subjects failed to reason analytically. They were misled by perceptually salient aspects of the situation. They resisted accomodating to additional information.…

A propositional logic game which is a subtest of the new British intelligence scale was analyzed to determine the extent to which skills proper to a single Piagetian period, formal operations, were hierarchically ordered. Item response patterns from 60 14-year-olds were categorized by means of ordering theory, a boolean algebraic measurement…

The purpose of this paper is to describe the development of children's measurement concepts and to outline implications of recent research on transitivity and counting. Discussion is confined to measurement of length and focuses on aspects of measurement outlined in the last two of Piaget's three measurement stages. It is argued that measurement…
