The president of Stanford University discusses his views on problems facing research universities, including research secrecy, ethics, and economics of proprietary knowledge generated in the university, faculty conflict of interest, place of humanities in a society driven by technology, and decline of government support for academic research.…

Sickle cell anemia is the most common and severe of inherited chronic blood disorders. In the United States, sickle cell anemia is most common among the Black population. Among the most commonly occurring symptoms are: an enlarged spleen, episodes of severe pain, easily contracted infections, skin ulcers, and frequent urination. (JN)

Potential sources of information and assistance on human genetics are identified, including a brief description of the National Clearinghouse for Human Genetic Diseases, genetic service centers, voluntary groups, state programs, commercial procedures, workshops, speakers, curriculum development aids, and general references. (DC)

Reflects on the century's preeminent benchmarks, including the evolution in the lives of people with disabilities and the prevention of many causes of mental retardation. The ethical challenges of genetic engineering and diagnostic technology and the need for new benchmarks in policy, practice, and research are discussed. (CR)

A model-fitting analysis of the covariance structure of an intelligence quotient (IQ) data set is reported using a model that considers additive and nonadditive genetic parameters and shared and nonshared environment parameters that permit different estimates for different types of relatives. The use of LISREL for such purposes is reviewed. (SLD)

Criticizes the Mitchell and Lawson (1988) report from the viewpoint of individual interview method. Provides Lawson's reply to the comment by showing differences in research philosophy and methods. (YP)

This article suggests that "The Bell Curve: Intelligence and Class Structure in American Life" (Richard Herrnstein, Charles Murray), a controversial book about the relationship of intelligence to social class, has exposed a wide chasm between two major paradigms concerning the forces that shape human behavior, and that the debate has…

A project developed to increase public and professional awareness of fragile X syndrome in New Jersey resulted in increased efforts at diagnostic screening, provision of client and family support services, and prevention. The program proved to be a cost-effective method for increasing community awareness of a genetic disease on a statewide level.…

Key components of human behavioral genetics and Sandra Scarr's work of the past two decades are critically reviewed based on scholarship in animal neuropsychology and clinical and educational psychology. Scarr's opinion that interventions to enhance intellectual development are ineffectual for children from abuse- and neglect-free backgrounds is…

This article offers a historical overview of the neurological aspects of dyslexia (originally seen as related to aphasia) and a review of familial and genetic factors in developmental dyslexia. Psycholinguistic models of dyslexia as they relate to neurological concepts are presented and the evolution of successful remedial methods is summarized.…

An activity that introduces students to the concepts of independent assortment of alleles during meiosis and gametogenesis, the richness of the variation that occurs as a result of allele recombination, and the unique phenotypes of offspring. Reproducible handouts with the directions and model chromosomes are provided. (KR)

A multivariate hierarchical model of specific cognitive abilities was fitted to data from 196 adopted and 213 nonadopted children from the Colorado Adoption Project and 120 of their siblings to assess genetic influence on specific mental abilities. Genetic effects occur in middle childhood that differentially influence mental ability scores.…

The problem-solving behaviors and genetics concepts employed by experts and novices during interaction with the computer simulation CATLAB, were examined. Thirteen subjects (3 experts and 10 novices) investigated a common hypothesis on a specific genetic trait during the computer activity. Using naturalistic research methods, general patterns of…

Describes research on the development of chronic conduct problems in childhood and adolescence, examining a multiple risk-factor model that includes biological predispositions, ecological context, family processes, peer influences, academic performance, and social information processing as factors leading to conduct problems. The paper describes a…

Reports on the results of a survey meant to ascertain the views of 16- to 18-year-old students (n=778) on using animals in medical research. Suggests that students have no greater objection to the use of genetically engineered animals over naturally bred animals in medical research. Contains 16 references. (Author/WRM)
