Research on historical cognition has capitalized on developing the thought processes of expert historians in students. Biofunctional theory points to several limitations to this approach: (a) developing from novice to expert is probably not a direct process; (b) developing expertise requires more time than the historical thinking approach…

The ontogeny of self-injurious behaviour exhibited by young children with developmental delays or disabilities is due to a complex interaction between neurobiological and environmental variables. In this manuscript, the literature on emerging self-injury in the developmental disability population is reviewed with a focus on an operant conceptual…

One hundred and thirteen sources of information published between 1904 and 1976, including a thorough coverage of scientific papers and representative journal and newspaper articles, are listed in this bibliography on the bio-rhythm theory. Developed in the early 1900's, this theory postulates that all humans experience regularly recurring…

The role of neurological, biological, developmental, and allergic factors in producing hyperactivity is examined, and the nature of such modifying factors as the child's basic temperament and personality is analyzed. (CL)

Describes the use of Rasch analysis to elucidate biological patterns of disability present in the functional ability of persons undergoing medical rehabilitation. Uses two measures, one for inpatients and one for outpatients, to illustrate the approach and provides examples of some biological patterns of disability associated with specific types…

Through examining the case of people with epilepsy (which, as we demonstrate, has an ambiguous status in relation to both popular and academic conceptions of disability) we explore the fluid, negotiable and contingent nature of identity and, in particular, the identification as "disabled". Disability, we argue, cannot be reduced to either biology…

While both positive and negative peer interactions have long been a focus of scientific interest, much less attention has been given to children who tend to refrain from interacting with peers. This volume brings together leading authorities to review progress in understanding the development, causes, and consequences of shyness and social…

Analysis of various statistics from birth records of 317 consecutive births revealed that twins are nonrepresentative of newborns with respect to birth weight and gestation, with male pairs to same-sex pairs the least representative. Differences between Negro and Caucasian twins were also found. (MH)

Girls who are overweight tend to perform poorly in mild athletic activities. (CK)

This biography explores the many scientific interests and contributions of Francis Galton and outlines his psychological studies as a "detour" from his major works that lasted from 1877 to 1885. Galton's interest in heredity was a focus of the second half of his life, the first having concentrated on geography and exploration. (SLD)

Archival data on 4,462 military veterans linked higher levels of serum testosterone to lower-status occupations. A structural equation model was supported in which higher testosterone, mediated through lower intellectual ability, greater antisocial behavior, and lower education, leads away from white-collar occupations. Contains 49 references.…

Near the end of his illustrious career, Gottlieb lamented the continued dominance of heritability analysis in human psychology and the difficulties in winning support for the developmental point of view. Recent, spectacular progress in molecular genetic neuroscience and the genetic study of behavior, however, is rendering heritability analysis…

This article examines Gene x Environment (G x E) interactions in two comorbid developmental disorders--reading disability (RD) and attention-deficit/hyperactivity disorder (ADHD)--as a window on broader issues on G x E interactions in developmental psychology. The authors first briefly review types of G x E interactions, methods for detecting…

A recent flurry of reporting in mainstream media argues that boys are drowning in a female-centered U.S. education system. According to proponents of the boy crisis argument, boys are just biologically and developmentally different from girls, and it is educators' responsibility to teach to this perceived difference. The U.S. education system,…
