Describes gender-based imagery preferences in research studies and instructional design, and the relationship of stages of aesthetic development to gender-based imagery preferences. Also provides four guidelines for selecting images for various purposes and discusses implications for further research to understand the impact of gender-based visual…

Comments on an earlier paper by Lerner and von Eye on sociobiology and human development; general theory in science, especially evolutionary theory; adaptation and behavior plasticity; and modern behavior genetics. Examines assertion that "heritability says nothing about the extent to which a trait is commonly inherited." Discusses…

Examines current views in Great Britain on the genetic basis of violence and crime. Argues that evolutionary heretics have a flawed understanding of genetics and defend an anti-scientific concept of free will. Maintains that arguments within Darwinism have allowed evolutionary heretics to promote their own agenda and to continue to abuse the most…

There is a growing awareness among scientists and researchers in every field that the selection of problems for research, the guiding theories, the interpretation of evidence, and resulting conclusions can be, and in fact often are, shaped by political or social ideology. If infused with keenly critical vigilance, such awareness affords the best…

Attention is drawn to the ways in which current conceptions of intelligence and its measurement differ from those which were generally accepted in 1928. The following principles underlying intelligence testing were generally agreed upon in 1928: (1) the assumption of intelligence as a recognizable attribute, responsible for differences among…

Reviews early theoretical and research literature on handedness and places it within the larger context of the nature-nurture controversy. Discussion focuses on Baldwin's study of the development of hand preference in infants in relation to the recapitulation theory, mental development ("dynamogenesis"), and speech development.…

This article reviews Raymond B. Cattell's important contributions to intelligence testing and the theory of intelligence. His theory of fluid and crystallized intelligences and other high-order factors of cognitive ability has offered the most well-founded and reasonable approach to an acceptable theory. (Author/BS)

Answers Sowell's charge that his work was misrepresented in an earlier article by Darity. Discusses Sowell's position on the relationship between culture and economic accomplishment, equality in the labor market, and the role of competition in the economic marketplace.(GC)

Discusses problems in both the "unfolding from within" and "enforcement from without" theories of children's cognitive development. Suggests that "mediation from above," which assumes that children are not independent beings, at least in the beginning, offers additional insight into children's interactions with adults. (WD)

Summarizes the positions of leading proponents of the belief in the biological basis of differences in intelligence, reviewing the ideas of Arthur Jensen, J. Phillipe Rushton, and the currently controversial "The Bell Curve" by Charles Murray and Richard Herrnstein. Relations between social perceptions of race and class are discussed.…

Identifies three main strengths of Casey's spatial ability model, but notes that a study by McKeever found different results concerning the relationship between familial handedness and females' mental rotation ability. Considers the use of a familial handedness measure to be a weakness of the model because handedness might not be an inherited…

"The Bell Curve" declares that studies of separated identical twins--the "purest" of "direct" methods for estimating IQ heritability--indicate a value of +.75-+.80. But, the main study cited suggests a heritability of "two-thirds" for the middle class, and Herrnstein and Murray neglect to mention numerous…

James Baldwin's ideas, such as that of a genetic science, and their influence on later theorists such as Piaget, Vygotsky, and Kohlberg, are described. The further Baldwin moved from the study of infancy, the more speculative and the less empirically verifiable became his ideas. (BC)

Illustrates contribution of genetic and environmental factors to differential ratings of within-family behavior and environmental differences. Maintains that, assuming differential ratings are a linear function of underlying trait differences, it is simple to recover within-family statistics, offering a more legitimate basis than comparing mean…

Discussion of the development of mathematical talent in students identifies seven distinct levels of talent and suggests that Srinivasa Ramanujan, the Indian mathematician considered to be self-taught, actually received good schooling and studied a comprehensive advanced mathematical text. This suggests that good instruction is as necessary for…
