This study compared affective responses to written and oral presentations of triadic situations of three groups: fourth graders (concrete operational), eighth graders, and freshmen in college (formal operational) to see whether the variation in stimulus mode produces a different kind of response in the eighth graders.

Findings indicate that (1) development of probability reasoning can be shown by an increasing monotonic trend with age, (2) verbal tests assess different aspects of this development than do nonverbal tests, (3) Piaget's ontogenetic age brackets are accurate, and (4) sex and intelligence are not significant variables.

This paper examines the nature of human abilities in light of recent advances in information-processing and discusses implications of these developments for cognitive assessment of children. (CJ)

The article reviews the development of mathematics error analysis as a means of diagnosing students' cognitive reasoning. Errors specific to addition, subtraction, multiplication, and division are described, and suggestions for remediation are provided. (CL)

Reports a two-year longitudinal study of 55 adolescents and young adults who were divided into three groups and given Reflective Judgment Interviews and the Concept Mastery Test to investigate sequentiality of reflective judgment stages. Results indicate support for seven hypothesized shifts in epistemic assumptions over time.(Author/RH)

Adaptations of simultaneous and successive processing and language tests were administered to 88 institutionalized moderately mentally retarded adolescents and adults. Results revealed a relationship between language and coding processing and demonstrated the involvement of serial processing in the comprehension of speech flow and language…

Describes components contributing to memory development, including: (1) capacity or processing allocation features of the information processing system; (2) strategies or control processes for problem solving; and (3) knowledge or semantic features acquired through experiences. Empirical evidence is reviewed supporting the psychological reality of…

Many researchers, wishing to generalize to large numbers, have turned away from Piaget's measurement techniques to group paper-and-pencil tests. The psychometric properties of these tests and their statistical links with other constructs are examined, along with the relationship between the observed products of mental effort and their underlying…

This discussion is primarily designed to increase teachers' awareness of Piaget's theory of cognitive development and implications for mathematics in the middle school. It is hoped such awareness will compel instructors to adopt strategies that help pupils gain more from mathematical experiences, by providing impetus for innovation and…

Three experiments were conducted to examine children's use of multiplying and proportionality rules in judgments of area. In the first two experiments, 7- through 8-year-olds were asked to judge the area of rectangles. In the third, 8- through 11-year-olds were tested on ratio of a rectangle compared to a horizontal line. Results indicated…

The hypothesis that overall-similarity relations structure both adults' and children's classifications of heterogeneous objects (objects that differ in a variety of ways) was supported in two experiments. When objects varied simultaneously on many dimensions, adults and children constructed classifications that maximized within-category similarity…

Proposes the cognitive developmental paradigm for developing and teaching career development courses in secondary schools. Proposes the major Piagetian constructs of interaction, equilibration, assimilation, and accommodation as a means of intervening in both the structure and function of the career thinking of adolescents.
