Presents a theoretical discussion of the role of cohort effects in the study of human development. The paper examines three problems associated with cohort analysis. These involve the interrelated problems of defining boundaries, defining distinctive experiences, and analyzing typical response patterns. (BD)

This critique points out weaknesses regarding the test measures used by Munsinger and Douglass and questions the validity of these measures for the ages of the children used in their study. (JMB)

Cross cultural psychology is considered as a methodological strategy, as a means of evaluating hypotheses of unicultural origins with evidence of more panhuman relevance, and as a means of developing new theoretical psychological phenomena. (Author)

Shows that the variables "educational level" and "low personal involvement" can predict "no opinion" and "don't know" responses in polls. (RL)

Discusses security problems associated with the open publication of research relating to "unsolvable" codes. (SL)

This paper suggests that, at present, a science of natural developmental processes does not exist because few studies are concerned with development as it transpires in naturalistic environments and because truly developmental data are not collected or analyzed. (Author/JMB)

The activities of a research working group are described. The investigators from several institutions coordinate their work on space and geometry. Underlying assumptions of the group and issues faced by it are described. (SD)

It is argued that research settings should be chosen with the whole experimental design in mind and that the availability of appropriate controls (groups or occasions for observation) should be as important as the suitability of the treatment group. (Author/AM)

The intent of this paper is to demonstrate that the standard age effect in analysis of variance provides an ineffective means of assessing developmental change when several age levels are involved and a roughly monotonic trend can be expected. (Author)

States that educational researchers have very little knowledge that they know for certain. Provides an overview of the relationship between research and philosophy, addressing three questions: (1) What is real in education? (2) What can be known about educational reality? (3) What is the relationship between educational research and what we know…

Uses a case study to illustrate problems associated with historical reasoning. The problems highlighted are confusion over the difference between reason and cause, enthusiasm of the antiquarian, misguided search for "essence," misconceptions as to when to quantify, propagandistic tendencies, equating sensationalism with importance,…

Research on rape is handicapped by a paucity of accurate information on frequency of rape. The randomized response technique, designed to produce reliable information in surveys of sensitive issues, is advocated as a means of uncovering true frequencies. Findings are discussed in the context of results from traditional surveys. (Author/ABB)

Offers a reassessment of the feasibility, even given "ideal" conditions, of conducting relevant research on the dynamics that take place in self-help groups. Examines kinds of changes, group methods, group members, group leaders, and environmental conditions. (Author/ABB)
