Two experiments investigated developmental aspects of the two components of scientific reasoning: induction and deduction. In the first experiment, 98 subjects, ages 5 through 11, inductively identified four silhouetted pictures by removing, one at a time and in any sequence, as few covering pieces as possible. Results indicated that: (a) the…

The purpose of this study was to investigate the effectiveness of CEMREL's Language and Thinking: New Directions Program, a broadly based early learning program in the teaching of basic language and reasoning skills. The program is a hierarchical skills oriented approach which provides a broadly based set of guidelines for teachers; a wide array…

This study attempts to determine if individual differences in multitask performance are due in part to the cognitive competence (i.e., the consistent, rule-based strategy) the subject brings to the task. A battery of learning (discrimination shift, transposition, incidental learning and paired-associate learning), cognitive-developmental…

This report provides data from a larger study investigating consumer socialization of children which focused on the processes by which children acquire knowledge skills and attitudes related to consumer behavior. The research has utilized two theoretical perspectives: cognitive development and information processing theories. The data reported are…

This review and critique examines cognitive developmental theory and research concerning the development of gender knowledge, and social learning theory and research concerning the development of sex-role stereotypes. A preliminary integrated model of the development of gender knowledge and sex-role stereotypes in young children is presented.…

Analysis of the free speech of one- to three-year-olds (N=21) found that measures of mean length of utterance (MLU) are positively related to age, are reliable, and can predict grammatical development, although there are identifiable points in the developmental evolution of MLU and MLU-like indices beyond which their reliability and validity have…

The performance of 40 hearing and 40 hearing-impaired children, aged two-five years, was compared on a battery of nonverbal tasks and a nonverbal intelligence test. Age significantly affected the results, consistent with a developmental change. In cognitive development, the hearing-impaired children were comparable to same-age hearing children.…

Examines cognitive processing and semantic influences on the developmental patterning of everyday social explanation in a cross-cultural investigation undertaken among American and Hindu adults and children (ages 8, 11, and 15). (HOD)

Tests causal models of verbal and performance IQ in 69 Mexican-American children of low socioeconomic status. Years of mother's education were correlated with IQ at 3 years and at 6 to 8 years, but traditional/nontraditional attitudes showed conflicting correlations over time. The adequacy of standarized IQ tests for this population is questioned.…

A total of 72 children, 36 each from first and sixth grades, were given a 70-item study list followed by a recognition test list of equal length. To indicate the relative dominance of features encoded at both ages, labels, pictures, and referents were recombined to form visual, semantic and acoustic distractors. (MS)

This brief paper summarizes warning signs of learning disabilities in preschool children, elementary school children, and secondary school children. It notes that learning disabilities are presumed to arise from dysfunctions in the brain resulting in significant difficulties in perceiving information, processing and/or remembering information,…

Two experiments were designed to investigate among kindergarten through third-grade children the development of character constancy -- the belief that other's or self's personality characteristics are stable across time and do not change despite changes in appearance. It is proposed that character constancy of self and other is a product of both…

Investigated the use of organizational schemes in memorizing prose. Adult organizational schemes were a function of the structure of material to be remembered and the individual's plan to recall the material. Age and sex differences were discovered in an experiment assessing developmental changes in recall plans of children and adults. (Author/DB)

Examined the reactions of 201 elementary school children to direct and indirect help and the moderating effects of grade, understanding of personality, and sex on children's reaction to aid. Results indicated that children high in the understanding of consistency of personality were more autonomous in the indirect than the direct help condition.…

Examined the types of play mothers introduce in direct response to their toddlers' play and the actual maternal play behaviors. Findings suggested that mothers tend to play with their toddlers in ways that might promote their children's development and that mothers with more knowledge about play development provide their children with…
