Does the pot melt, boil, or brew? Black children and white assessment procedures

The experiences Black youths bring to school with them constitute a distinctive, viable culture. Their subsequent performance in educational and psychological testing situations cannot be assessed adequately without consideration of their particular attitudes, perceptions, and behavioral patterns, for all of these are determined by a kind of cultural conditioning which differs, in some fundamental ways, from mainstream Americans. Several of the social and psychological characteristics of Black culture are discussed. Included are Blacks' attitudes toward whites, systems of time allocations, expressions of identity, attitudes toward learning, dissemination of information among Blacks, Black learning styles and maturation processes. Each is discussed further in terms of its manifestation in a testing or assessment situation; how it conflicts with the assessor's orientations and expectations; and how distorted, unreliable evaluations result from the failure of assessors to consider implications of cultural relativism in interpreting Black behavior.     

Validating a selection test,a predictive probability approach

The problem of inferring the validity of a selection test (x) as a predictor of some criterion (y) when completexy data are not available is investigated. The basic approach is to construct the predictive probability distribution of the unobservedy scores and then derive interval estimates of the least squares regression weights, the difference in averagey scores for selected and unselected cases, and the residual variance in predictingy fromx. Further, an approximation to the predictive distribution of the squared correlation betweenx andy in a future group is derived.     

On the matrix formulation of Kaiser's varimax criterion

The author provides a full-fledged matrix derivation of Sherin's matrix formulation of Kaiser's varimax criterion. He uses matrix differential calculus in conjunction with the Hadamard (or Schur) matrix product. Two results on Hadamard products are presented.     

The menstrual taboo in the Judeo-Christian tradition

The menstrual taboo continues to be a primary reason why women in Judaism and Christianity are excluded from positions of authority. This is demonstrated by examining positions taken toward menstruation by religious leaders in past history and in the present day. Jesus and Gregory the Great are notable exceptions to the disdain expressed by male religionists toward menstruants. Only after the removal of this persistent taboo will religious bodies come to treat women as full participants.     

Psychotherapy and the locus of control

Underlying various actions of both the therapist and the patient are expectations about the measure to which an individual's experiences are the product of powerful external forces or of the person's own actions and decisions. While most of our anthropological theories support the notion that a person's experience is subject to an external locus of control, neither that view nor the opposite emphasizing freedom and autonomy is adequate for the therapeutic enterprise. THere are elements of truth in both positions that ned to be incorporated in therapeutic expectations if the enterprise is to proceed in an orderly fashion.     

Functional reading for students with developmental disabilities who are linguistically diverse

Students with moderate and severe disabilities often have language deficits that make the acquisition of reading challenging. Sight word instruction of daily living skills is one method of intervention that benefits students with severe disabilities who have not achieved literacy. When students with developmental disabilities are also linguistically diverse, acquisition of reading skills becomes more complex. Sight words must be chosen that are relevant to the students own community. A critical decision in planning sight word instruction is whether to provide instruction in the student's primary language or in English. These issues are discussed and an illustration is given of the heterogeneity among students with developmental disabilities who are linguistically diverse.     

Is science socially constructed—And can it still inform public policy?

This paper addresses, and seeks to correct, some frequent misunderstandings concerning the claim that science is socially constructed. It describes several features of scientific inquiry that have been usefully illuminated by constructivist studies of science, including the mundane or tacit skills involved in research, the social relationships in scientific laboratories, the causes of scientific controversy, and the interconnection of science and culture. Social construction, the paper argues, should be seen not as an alternative to but an enhancement of scientists’ own professional understanding of how science is done. The richer, more finely textured accounts of scientific practice that the constructivist approach provides are potentially of great relevance to public policy. This paper is based on a Topical Lecture presented at AMSIE'96, the 162nd National Meeting of the American Association for the Advancement of Science. Baltimore, Maryland, 8–13 February 1996.
