Reports a study of the correlation between intellectual development and students' understanding of scientific concepts and science processes. Results are reported concerning the reliability and validity of Piagetian or Piagetian-like tasks as measures of students' level of formal reasoning. (Author/SA)

Describes a study which sought to develop a criterion-referenced cognitive instrument based on the 83 performance elements contained in 30 teacher education modules. Discusses whether it is educationally sound to conclude that those who possess appropriate teaching skills also possess an appropriate cognitive base. (JOW)

Adapting curricula to the cognitive developmental level of students has been hindered by the difficulty of assessing those levels in students. The reliability and validity of a paper-and-pencil Piagetian assessment are discussed. (Author/ JKS)

Reviews two models of thinking and intellectual development: Scandura's deterministic model of structuralistic learning, and a generalization of Rasch's probabilistic latent trait model. Models are compared by means of two experiments with balance scale tasks. (RH)

Argues that Bartsch and Wellman are successful in analyzing natural language to understand the emergence and development of a theory of mind in everyday social interaction. Discusses their delineation of the transition from a focus on desire to a concept of belief, and describes their views on contextual and cultural variables in theory of mind…

Presented a battery of false belief tasks varying in type of belief questioned, target for belief ascription, presentation of reality information, and deception context to Head Start children. Found that performance was better on locations tasks than on contents tasks and with older children compared with younger children and that performance was…

This study examined 6- to 8-year-old Slovenian children's acquisition of matrix completion proficiency and compared microgenetic and age-related changes on the task. Microgenetic analyses indicated that: variability of children's errors increased before they discovered the correct strategy, the correct strategy became dominant shortly after…

Describes a woman who maintained high cognitive test scores until her death at 101 years of age despite anatomical evidence of Alzheimer's disease. The woman was part of a larger "Nun Study" in which 678 sisters donated their brains to teach others about the etiology of aging and Alzheimer's disease. Findings are discussed. (RJM)

Investigated four hypotheses formulated by Jensen with regard to his theory of the relationship between cognitive abilities and socioeconomic status. Preschool children identified in the upper SES level performed with more accuracy on both levels of tasks as defined by Jensen. (Author/SDH)

Recent research studies and texts in composition demonstrate the growing belief that students' difficulties with the writing tasks assigned to them are inextricably linked with their difficulties in handling complex cognitive processes. Through appropriate writing activities, students can be provided with practice in the intellectual functions…

Piaget's egocentrism and Witkin's psychological differentiation are important constructs in theories of cognitive development. A comparison of these concepts could lead to an increased understanding of cognitive development in the older adult. In a test of Witkin's revised model of psychological differentiation, the Portable Rod and Frame Test…

In this study, six children were selected by age and were administered Piagetian tasks designed to measure their level of cognitive development against the hierarchical structuring of age/achievement posited by Jean Piaget. The task administrations are presented in detail with descriptions of the subject and the tasks, a verbatim report, and the…

The purpose of this study was to examine possible relationships between moral and cognitive development in second- and fifth-grade children. Sixty children were used in the study. Levels of cognitive development were evaluated using four learning tasks and moral development was assessed by presenting four conflicting situations to each subject for…

Reported is one of a series of investigations of the Project on an Information Memory Model. This study was done to test an information memory model for identifying the unit of information structure involved in task cognitions by humans. Four groups of 30 randomly selected subjects (ages 7, 9, 11 and 15 years) performed a sorting task of 14…

Reported are the results of a study of the Piagetian formal thought range of 3600 students, 13 to 15 years old, in seven countries: Denmark, Sweden, Italy, United States, Austria, Germany, and Great Britain. Cognitive measurement was obtained by group administration of two tasks to assess proportional reasoning and control of variables. Overall…
