This article introduces the special issue of the journal on the topic of youth violence as adaptation to community violence. Contrary to the predominant perspective that youth violence is a sign of dysfunction or maladaptation, the articles collected here consider whether some youth violence may have positively adaptive consequences in the face of…

Examines the meaning of reaction time (RT) and the possibility that it may predict other cognitive and motor skills in the first year of life. Considers two competing models that specify the information-processing components underlying RT performance. Describes the neural data needed to definitively choose between the models and considers…

Two perspectives of descriptive research are discussed: first-order, which describes the world as it is; and second-order, which describes the world as people experience it. The latter perspective is known as experiential description. Research in a variety of disciplines, notably the work of Darwin, Werner, and Piaget, has provided experiential…

Among the factors least likely to be given due consideration, especially in computer assisted instruction, are student variables. Some reasons which might have hindered research activities involving student, and possibly teacher, cognitive mapping behaviors, learning styles, and media preferences as variables in experimentation are summarized: a…

Reported are a series of studies revealing developmental and individual differences among preschool children on relationships between gender-based knowledge, gender constancy, gender schematic processing, recognition memories for gender-typed information, and flexibility, sequencing, and understanding of gender scripts. Alternative approaches for…

The time may be ripe for the fields of mathematics education, special education, and cognitive psychology to converge, with their respective focuses on mathematical problem solving, individual differences among students, and analysis of cognitive processes. Four articles on learning disabilities in mathematics are introduced, and a research agenda…

Explanations for differences in reading proficiency should be constructed around an atlas of reading-related individual differences in cognition. Such an atlas should include well-documented "bottom-up", text-driven reading strategies and less thoroughly investigated "top-down", schema-driven reading strategies. Research…

The construction of cognitive tests is largely based on a Thurstonian model of the structure of the intellect, with test content described in terms of loadings on broad constructs called factors. Knowledge of factorial content of a test does not necessarily correspond to knowledge of mental activities elicited by test performance. Modern cognitive…

Statistical methods employed to test individual differences in dual-task performance and the existence of a general time-sharing ability are reviewed and critiqued. Specifically, both the types of data being collected and the types of data analysis procedures have been inadequate to the critical evaluation of a hypothetical…

The purpose of this report is to distill curricular and testing implications of brain research. The report will focus on three topics. One topic is the possibility that brain lateralization--that is, the degree to which the two brain hemispheres specialize in different types of information processing--is an individual differences variable that…

Reading encompasses a wide range of verbal processes, among them such simple verbal processes as word decoding, letter recognition, name retrieval, and semantic access. The question is whether simple verbal processing differences are adequate to account for general reading ability differences. Across different verbal domains and different ages,…

Over the last 15 years or so, research into measurement error has begun to consider not just whether the test items fit, but whether the people who answer the items fit. Attempts to systematically identify people who do not fit the typical pattern have led to several "person-fit statistics." This digest describes the need for such…

Identifies contributions of Liben and Bigler's studies to gender development related to measuring self and other sex typing, developing a theoretical account of the self-other relation, and incorporating individual differences. Raises questions about measures used and interpretations of the findings. Suggests issues for future research:…

An ongoing series of experiments has extended Rose's information processing approach to job performance assessment. Each study investigated cognitive tasks from the literature on memory, psycholinquistics, and visual information processing, for potential inclusion in the test battery. Each task was then evaluated against three criterion areas: (1)…

Issues in the testing of bilinguals are examined, particularly in the context of poor results attained on standardized tests by bilingual children. Discussion begins with an examination of definitions and classification of bilingualism, citing some evidence of confusion in use of terminology. Causes for this confusion are seen in popular…
