Discusses how genetic data on present human population relationships and data from the Pleistocene fossil hominid record are being used to compare two contrasting models for the origin of modern humans. (TW)

Described are the history of the study of language disabilities, briefly outlining the work of Samuel Orton, Judson Herrick, Adolph Meyer, and Paul Schilder; Lauretta Bender's development of the Bender Visual Motor Gestalt Test; and the basic principles of language disorders, including familial patterns, maturation lag, plasticity, and nonfixated…

Discusses a single pattern formation mechanism that could underlie the wide variety of animal coat markings found in nature. Presents the results of a mathematical model for how these patterns may be generated in the course of embryonic development. (CW)

Proposes the concept of relative functionalism, under which Asian Americans perceive and have experienced restrictions in upward mobility in occupations unrelated to education. Consequently, educational achievement assumes…

Reports on the findings of several studies into the genetic similarities of twins. Focuses on the relationships between personality and behavioral genetics and argues that genetic similarity seems to be a better predictor than environmental factors. Discusses psychopathology, cognitive abilities, and personality. (TW)

Maintains that even a cursory reading of "The Bell Curve" reveals a skewed methodology that deliberately ignores relevant data. Includes statistical tables illustrating the relationship between environmental factors and test scores. Contends that the basic purpose of "The Bell Curve" is to justify economic racism. (MJP)
