The assumptions that biological differences between the sexes are universal, inevitable, and desirable, and that they justify the social inequality of the sexes, were examined. It was suggested that feminists base demands to remedy this imbalance on the proposition that sex differences are due to both nurture and nature. (Author/KR)

Theories of biological determinism in relation to sex role differences are examined for their scientific merit and for their possible political impact. The study of the biological basis of behavior by evolutionary principles is highlighted as a typical scientifically flawed theory, and propaganda in defense of the status quo. (Author/KR)

Early land plants and their ancestry remained an important, controversial issue in paleobotany this past year. Current research and theories on the subject are reviewed. (MA)

Argues that awareness of neuro-biology is necessary to insure accountability and to remain cognizant of the developing technology in this area, whose impact on the black community is increasing. It is up to the community and to black professionals to insure accountability, since scientists (and certainly those people who utilize this technology)…

A dialectical approach is used to explore the relationship between individual specialization, collective adaptation, and rate of environmental change for both higher and lower organisms. The nature-nurture controversy and the "generation gap" are discussed in terms of this interrelationship. (BD)

Socialization research over the past 25 years has been affected by changes in social practices and in scientists' conceptualizations of the nature of children. Socialization is presently viewed as a function of the family and of social institutions and public policies. It also considers the importance of biological functions in development and the…

This paper presents a critique of recent attempts to explain psychological differences between the sexes in terms of biology. (BD)

Considers effects of reframing problems of patients seeking psychotherapeutic treatment as "family problems." Asserts that when biologically based deficits in identified patient are salient determinant of interpersonal dysfunction, such reframing is inappropriate. Recommends psychoeducational strategies for treating families of persons with…

Notes that preschool compensatory education has not resulted in any appreciable, durable gains in I.Q. or scholastic achievement. Posits that compensatory programs remedied deficiencies in knowledge but not in cognitive processes. Suggests further research into the nature of intelligence and its malleability. (PGD)
