For some, research in learning and teaching of a second language (L2) runs the risk of disintegrating into irreconcilable approaches to L2 learning and use. On the one side, we find researchers investigating linguistic-cognitive issues, often using quantitative research methods including inferential statistics; on the other side, we find…

This volume includes 3 papers based on presentations at a workshop on communicating assessment information to particular audiences, held at Educational Testing Service (ETS) on November 4th, 2010, to explore some issues that influence score reports and new advances that contribute to the effectiveness of these reports. Jessica Hullman, Rebecca…

J.H. Kranzler and A.R. Jensen report on a reanalysis of previous data that is again inconsistent with the hypothesis that psychometric "g" is unitary. J.B. Carroll reiterates objections to the evidence that Kranzler and Jensen offer in support of a composite "g." (SLD)

Ratcliff (1985) simulated data from three letter-matching experiments with his diffusion model. The necessity of including a comparison criterion is consistent with the conclusion of Proctor, Rao, and Hurst (1984) that bias of response criteria, alone, is insufficient to generate the fast-same phenomenon.

Contrasted three major theories on attitude change: cognitive dissonance, incentive, and social judgment. Results from student questionnaires provided little support for cognitive dissonance. Also provided credible, though overlapping, evidence for incentive and social judgment theories. Improvised role playing produced more change than did…

Five papers discuss the current and potential contributions of information-processing theory to our understanding of mathematical thinking as those contributions affect the practice of mathematics education. It is concluded that information-processing theories need to be supplemented in various ways to more adequately reflect the complexity of…

Three articles explore current research and theory regarding children's learning styles, covering: (1) four basic ways children approach learning and corresponding teaching methods; (2) "multiple intelligences" and new thought about the boundaries of innate ability; and (3) classroom teachers' perspectives and instincts about the mystery of…

This special section on cognition and mathematics contains an introduction and 13 articles on advances in the psychology of mathematics learning. The articles focus on how students learn to solve mathematics problems, including arithmetic computation problems, arithmetic word problems, and computer programing problems. (SLD)

The seven articles of this theme issue bring together recent theoretical work in investigating the kind of conceptual change that occurs in the learning of the physical sciences. How conceptual change occurs and the implications for science instruction are considered. (SLD)

Twelve papers on the emergence and maintenance of severe clinical depression and depressive symptoms during adolescence are presented. Topics include parental influences, epidemiological data, depressive and negative affect, hormonal effects, preadolescent symptoms, sex differences, longitudinal studies with rhesus monkeys, suicidal ideation,…
