Effects of object training and photograph training on comprehension of category labels by 10 severely mentally retarded children and adolescents were explored. Results indicated that acquisition and transfer did not differ, yet generalization was significantly more accurate with objects than with photographs. Futhermore, generalization was…

Cognitive activity of children from 1.5 to 5 years of age participating in problem solving and in spontaneous play was analyzed in terms of the successive coordination of existing patterns and the incorporation of new mental components. Analysis identified a series of developmental levels. (Author/RH)

Discusses advantages and disadvantages of standard high school biology and chemistry course sequences. Relates these sequences to Piagetian developmental levels as well as to David Ausubel's cognitive theory. Suggests that the sequences be reexamined in light of issues considered. (JM)

On the basis of a study involving 40 first-grade students, compares Pascual-Leone's and Keating and Bobbitt's developmental theories of information processing by contrasting their predictions about a classification task. Results falsified Keating and Bobbitt's model. Predictions from Pascual-Leone's theory were almost wholly confirmed. (RH)

This study distinguished between forms of self-consciousness (private self-consciousness and social anxiety) and investigated the effect of self-esteem, vulnerability to criticism, and the tendency to fantasize on each. A structural equation analysis used unobserved variables from a sample (n=1098) of adolescents, ages 12 to 19. (Author/BS)

By enhancing the cognitive abilities of teachers, supervision can help them make better instructional decisions in planning (the preactive stage), teaching (the interactive stage), analyzing and evaluating (the reflective stage), and applying (the projective stage). Seven charts and a 33-item reference list are provided. (DCS)

Focuses on environmental influences on variations in infants' exploratory behavior, the stability of these differences, and the relation between differences in exploratory play and later cognitive development. (AS)

Assesses the hazards of models of cognitive development and the positivist views of language that support them. Considers how alternative views of language and learning can help develop a method of teaching that views reading and writing as interpretation and the making of meaning. (RBW)

The failure of compensatory education programs to demonstrate permanent increases in intelligence with early intervention has constituted a basic challenge to the validity of the early experience paradigm. A reconceptualization of the effects of early experience, emphasizing the cumulative and dialectical nature of development, is needed. (KH)

Educators can improve children's thinking skills through the following five steps: (1) identifying and defining the desirable thinking skills, (2) identifying the components of these skills, (3) providing systematic skills instruction, (4) integrating the teaching of thinking skills with various content areas, and (5) improving skills testing.…

Determined that males (N=70) demonstrate higher level of intellectual development than females (N=70), that males mature intellectually earlier than females, and that there appear to be factors other than age and sex that are related to development of formal operational reasoning. Implications of these and other results are discussed. (JN)

The renewed interest in teaching thinking skills results from concern about the failings of the current system. Some thinking skills programs emphasize cognitive processes, while others are concerned with heuristics, development of formal operations, language and symbols, or thinking as subject matter. (TE)

Analyzes the exploratory patterns of 112 children ages 4 to 12, using visual and auditory stimuli and toy preference and toy exploration tasks. Finds that a preference for complexity and for unknown toys increases with age and notes age differences in exploratory patterns and question-asking behavior. (Author/CB)

Reviews empirical research on the development of ethnic attitudes and finds overlapping sequences: (1) progression from a focus on oneself to a focus on groups, and then on individuals; and (2) progression from affective to perceptual to cognitive forms of differentiation. Also discusses differences between majority and minority group children.…

This article reports the findings of a research project on public and private high schools in the United States. The principal researchers found that Catholic schools and non-Catholic private schools are more effective than public schools in helping students to acquire cognitive skills. (SSH)
