Little formal training in skills is given with undergraduate courses in chemistry. A possible remedy is the introduction of specially devised exercises for skill development in logical argument, problem solving, appreciation of scientific limitations, fluent and grammatical writing and speaking, and decision making.

This article discusses a study designed to determine the order of acquisition of the two expressions "in front of" and "behind," using two featureless objects. (CFM)

Experimenters analyzed a prose passage into 350 idea units, then interspersed throughout the text pictures depicting main ideas, or both main ideas and nonessential details. For fourth- and sixth-grade subjects, pictures did facilitate both immediate and delayed recall, but only of main ideas. (Author/JEG)

Presents a descriptive analogy comparing Piaget's theory of intellectual development to the development of athletic abilities in order to provide insight into Piagetian theory. (SL)

Examined the relationship between maternal cigarette smoking during pregnancy and children's intellectual functioning through age four. Found that children whose mothers smoked 10 or more cigarettes per day during pregnancy had Stanford-Binet scores 4 points lower than those whose mothers did not smoke during pregnancy. (HTH)

Examined the origins of high general cognitive ability (g) in twins who were participating in the MacArthur Longitudinal Twin Study. Formed high g groups from the 19th percentile and above at each age. Results suggested increasing genetic influence and increasing genetic stability from 14 to 36 months and substantial genetic influences with…

This paper helps to clarify the role of empirical evidence in psychological and epistemological theories. Following Galileo's idealization, epistemological theories do not describe the behavior of individuals in the real world. It is only when the "impediments" of the real subjects are gradually removed by experimental manipulation that…

Reports on a study conducted to obtain indications of changes in mental level from high school through college and to investigate the relationship of cognitive level to SAT scores, college grades, and attrition. (PEB)

This paper examines the theories of Herman T. Epstein, who has suggested that there may be a correlation between Piaget's stages of intellectual development and the brain growth stages. Epstein's research has indicated that the human brain grows in spurts rather than in simple linear increments across time. Of special significance to educators is…

"More" and "less" were analyzed into two meaning dimensions, "occurence" and "quantity", which were hypothesized to be developmentally related to acts of addition and subtraction. (SBT)

This study examines the longitudinal relationships between mastery motivation and differentiated measures of intellectual development assessed at 1 and 3 1/2 years of age in a sample of 35 children (21 boys and 14 girls). At one year three types of mastery motivation were assessed using structured tasks: (1) producing effects (engaging in…

Five conference reports that originally appeared as monographs of the Society for Research in Child Development concern cognition in young children. Included in a section on thought are articles on Piaget and his theories, computer simulation on human thinking, and an information processing theory of intellectual development. The development of…

The development of children's humor is described, focusing on the cognitive aspect of what is funny and how this relates to children's intellectual growth. Cognitive elements that facilitate children's humor are identified as: (1) the ability to grasp incongruities, (2) the presence of an intellectual challenge, (3) timing, (4) novelty, and (5) a…

The differential visual responses of 20 Down's Syndrome and 20 normal infants (CA 8 months) to 13 pairs of visual targets were compared. Although DS subjects generally looked longer at the stimuli than normal subjects, they showed a response differential in only 3 stimulus pairs compared to 11 for the normals. Six of the stimulus pairs elicited…

Metaphors of similarity and proportionality, together with a pictorial form of similarity metaphors, proverbs, and several Piaget-type cognitive tasks, were given to 50 boys aged 5 through 13 years. Results indicated that metaphor comprehension is a type of classificatory behavior, the development of which is related to maturing cognitive…
