Findings of a series of sociological studies on American men indicate that job conditions facilitating occupational self-direction increase men's intellectual flexibility and promote a self-directed orientation to self and society. In addition, jobs that limit occupational self-direction decrease men's intellectual flexibility and promote a…

Findings from a study of 47 children between 3.5 and 12 years of age who received tonsillectomies at a children's hospital are presented. During a home visit before hospitalization, the child's adjustment, cognition, temperament, and family characteristics were assessed. Tonsillectomies were followed by an overnight stay at the hospital, and…

"Child as cultural apprentice" is a developmental psychologist's heuristic metaphor which is embedded in an individual-socioecological frame of reference. A basic theoretic feature of this metaphor is the explicit recognition of the interdependence of the process of child development and the socially provided resources for that…

The goal of this research synthesis is to evaluate the validity of the claim that there are fundamental limitations on the ability of adolescents to engage in critical thinking. Critical thinking is defined as an analytic, focused cognitive activity aimed at understanding phenomena at a root rather than a superficial level; a type of thinking…

Using a neo-Piagetian structural analysis, two studies examined developmental differences in the oral narratives of children aged four to ten years. The first experiment, reporting on 20 children at each of the dimensional substages (mean ages of 4.8, 6.1, 8.5, and 10.6 years), showed that a qualitative shift occurred between four and six years…

The teaching of critical thinking requires an understanding of the term, defined in this document as the processes of judgement or evaluation. Informal logic teaches students to understand and analyze arguments which are fallacious, to determine what is valid and invalid, and to evaluate non-deductive arguments. John McPeck and Richard Paul…

Many high school and college students seem to dislike mathematics, do poorly in the subject (as evidenced by declining test scores), and avoid scheduling courses in mathematics. Answers to why test scores are declining and why mathematics achievement is low among adults are speculative and as varied as the educators who offer them. However, one…

A study was conducted to test an hypothesis relating semantic structures to cognitive development, specifically that the mean number of associative complexes used by a group of children will be significantly greater than the mean number of associative complexes used by a group of adolescents. The word game "Password" provided a simulation of a…

To assess the relationship between specific neonatal variables and subsequent mental development, a longitudinal study of 41 children from a high-risk neonatal nursery was conducted. For each child, 58 measures of neonatal condition (e.g., head size, various laboratory values, delivery mode) were available, as were developmental assessments up to…

Discussed are results of studies of the cognitive development of 2- and 3-year-old children which suggest that the mind makes gains in the ability to think as gains in language development are made. "Thinking" in this context refers to the judgments children made as they selected objects and maneuvered them into one arrangement or…

The blockbuilding, painting, and oral expressions of young children provide evidence of a natural tendency to symbolize experience and to use the symbolic elements of expressiveness, creativeness, and living form. Up to the present time, educators have not fully grasped the fact that the need to symbolize is at the base of all education. They…

To investigate developmental differences, preschoolers' performance on four tasks frequently used to measure their understanding of causal and temporal relationships was studied. Based on an analysis of cognitive processes involved in recognition, completion, construction/seriation, and verbal explanation tasks, the prediction was made that…

Development and use of a rating scale to code videotaped mother-child interactions involving 1-year-olds with Down's syndrome are described. It is explained that the ratings were developed to describe individual differences in directiveness and sensitivity in mothers and social and cognitive maturity in the children, with a measure of mutuality or…

The relationship between affective responsiveness, synchrony of mother/infant interaction, and developmental status was examined in 32 normal infants (eight infants each at the ages of 4, 8, 12, and 16 weeks). Data were collected in infants' homes and included (1) naturalistic mother/infant play; (2) presentation of auditory, tactile, visual, and…

This paper discusses the interaction of cognition and physiological factors in emotion from the viewpoint of a developmental-interactionist theory of motivation and emotion. Emphasis is given to the role of cognition in the theory of emotion. The nature of cognition is discussed in terms of (1) the "primacy" of emotion versus cognition;…
