Studies on learning in infants show that in infancy every month of life represents a new level of learning. The functional state of the central nervous system can be influenced by physiological factors which cause fluctuating changes in functions important for learning. Once a stimulus becomes a conditioned signal, it acquires strong power in…

The application of Piaget's theory of cognitive development to the assessment of mental ability of the mentally retarded is presented. Following a discussion of developmental theories and diagnosis of mental development, testing interviews demonstrate the limits of cognitive thought at each of three stages. Abnormal intellectual oscillations are…

The first part of the paper presents a description of Piaget's theory of moral judgment and makes a case for the relationship between the theory and the phenomenological approach to self concept development. It is proposed that both the development of self concept and moral judgment are greatly influenced by the examples of and interaction with…

The study examined the effects of educational treatment on 62 children (5 to 16-years-old) in a care unit for ambulant, trainable, low-moderate, and severely mentally handicapped children. Educational programing was provided in four areas: gross motor, motor perceptual, language, and social training. Results showed that the experimental children…

Two basic concerns of this study were to discover if cognitive level affects a child's understandings about family and to explore the effects of social learning factors on a child's understandings of family. Subjects were 28 boys and girls at each of the three higher Piagetian cognitive levels who were each given a newly constructed interview…

This study examines the interactive roles of social, cultural, and cognitive developmental factors in determining children's moral and achievement judgments. A total of 1485 male and female Iranian children/students of diverse social background (ranging in age from 4-18) served as subjects. Subjects were asked to evaluate (reward/punishment) the…

Eighteen research reports related to mathematics education are abstracted and analyzed in this publication. Three of the reports deal with aspects of learning theory, seven with topics in mathematics instruction (problem solving, weight, quadratic inequalities, probability and statistics, area and volume conservation, cardinality), five with…

This study investigated 34 selected teacher characteristics that relate to cognitive and/or affective learning in elementary school. A questionnaire for identifying characteristics of effective teachers was developed and distributed to fifty graduating student teachers. Three questionnaires were excluded because they signified "None" on the…

Three studies to determine the effects of adult models on interrogative strategies of children (ages 6-11) are reviewed. Two issues are analyzed: (1) the comparative effectiveness of various types of modeling procedures for changing rule-governed behaviors, and (2) the interaction between observational learning and the developmental level of the…

This study examined (1) the level of symbolic capability as revealed in play, (2) the use of spontaneous vocal imitation, and (3) the nature of certain classes of words occurring in spontaneous infant language. Facets of child behavior were examined during the period of single-word utterances and early multiword combinations with a view to…

Two experiments which investigated the young child's ability to deal with multiplicative classes and relations (considered behavioral indices of concrete operations thought) in double series and cross class matrices are described and discussed. In the initial study, 160 children from preschool through grade 2 received six matrix subtasks…

Sixteen preschool-age hearing-impaired children were studied to explore the general nature of their cognitive development and to identify relationships between environmental processes and cognitive development. Data were obtained from administration of the Infant Psychological Development Scale and the Inventory of Home Stimulation (when Ss were…

This annotated bibliography focuses on recent publications dealing with factors that influence child growth and development, rather than the developmental processes themselves. Topics include: general sources on child development; physical and perceptual-motor development; cognitive development; social and personality development; and play.…

A modified form of Sigel's Styles of Categorization Test was constructed, permitting the independent measurement of Descriptive Part-Whole (DPW), Relational-Contextual (RC), and Categorical-Inferential (CI) categorizations. The test was administered to 243 5th, 8th, and 11th graders on two occasions. At each grade level, a majority of…

Aptitude treatment interaction (ATI), as applied to education, measures the interaction of personality factors and experimentally manipulated teaching strategies. ATI research has had dissappointingly inconclusive results so far, but proponents argue that this has been due to imprecise methods, which can be rectified. They believe that…
