Examines Vygotsky's notion of two main lines of psychosocial development--the natural and the cultural--in light of contemporary Marxist debates concerning the relationship between the "material" and the "social." Argues that an adequate account of Vygotsky's theory must ground the social construction of cognition in a…

Questions Moll's assumption, in this issue, of a parallel between processes in Vygotsky's natural line and the "material" processes in Marxist theories. Disputes Moll's characterization of the natural line providing a kind of constraining framework within which the cultural line can operate, suggesting that the two enter into a…

Examined the relationship between temperament and craniofacial variation in 372 infants observed at ages 4, 14, and 21 months. Found that high-reactive 4-month olds, who are predisposed to becoming timid, inhibited toddlers, had smaller bizygomatic ratios (narrower faces) at both 14 and 21 months compared to their low-reactive peers.

Reviews new documentation of the extent, timing, origins, dispersal mechanisms, and impacts of biological invasions in the Great Lakes basin. (ZWH)

This study of 11 3-generation families supported the hypothesis of autosomal dominant inheritance with reduced penetrance. Data did not support an increased frequency of males, left-handedness, or autoimmune disorders in dyslexics. Severity was greater in males. Long-term outcome was comparable in dyslexics and nondyslexics. (JDD)

Outlines a theory of rhetoric, sexuality, and embodiment that is both immoderately antifoundationalist and antirhetoricalist. Considers what in rhetoric or discourse exceed language, namely, desire, whether that be heterosexual or homosexual. Attempts to eliminate the stigma associated with the "gay Lacanian." (TB)

A study of 202 patients with autism found the incidence of a dodecamer duplication in the HOPA gene was not significantly different between patients and controls. Three female patients inherited the duplication from nonautistic fathers. Also, there was no systematic skewing of X inactivation in female patients with the duplication. (Contains…

In 1980, boys were four times as likely as girls to be arrested; today they are only twice as likely to be arrested. In this article, the author explores how the juvenile justice system is and should be responding to the adolescent female…

The prevalence and cost of chronic pain is a major physical and mental health care problem in the United States today.

Physicians have been treating hyperactivity in children with drugs as if it were a disease instead of a collection of symptoms which require exhaustive diagnostic tests to determine the underlying problem. (DB)

To account for observed sex differences on tasks such as the rod and frame test, the embedded figures test, and other related measures, the theory is advanced that a sex-linked recessive gene mediates or facilitates certain performances. This assumption is coupled with the concept of "a mixture of density functions" to provide a…

Environmental lighting exerts profound biologic effects on humans and other mammals, in addition to providing the visual stimulus. Light acts on the skin to stimulate the synthesis of Vitamin D. It also acts, through the eyes, to control several glands and many metabolic processes. Light, or its absence, "induces" certain biologic functions. Light…

Statistical analysis of the data in this research project indicates that neither the physical, emotional, nor intellectual cycles can be used to predict suicide behavior and also that biorhythms are influenced by environmental variations. (DS)
