The confounded nature of angry men and happy women.

Findings of 7 studies suggested that decisions about the sex of a face and the emotional expressions of anger or happiness are not independent: Participants were faster and more accurate at detecting angry expressions on male faces and at detecting happy expressions on female faces. These findings were robust across different stimulus sets and judgment tasks and indicated bottom-up perceptual processes rather than just top-down conceptually driven ones. Results from additional studies in which neutrally expressive faces were used suggested that the connections between masculine features and angry expressions and between feminine features and happy expressions might be a property of the sexual dimorphism of the face itself and not merely a result of gender stereotypes biasing the perception.

The impact of presentation graphics on students’ experience in the classroom

To investigate the benefits and perceived effectiveness of instructional technology, students enrolled in several courses were compared on student evaluations of instruction, grades and an attitudinal questionnaire. The instructors of the courses taught the same course across two successive semesters, using traditional “chalk-and-talk” methods the first semester, and PowerPoint the next; all other techniques (e.g., exams, lecture material) were held constant. Results suggest that organization and clarity, entertainment and interest, professor likeability, and good professor behaviors were enhanced with PowerPoint although final grades were not.     

Scaffolded writing and rewriting in the discipline: A web-based reciprocal peer review system

This paper describes how SWoRD (scaffolded writing and rewriting in the discipline), a web-based reciprocal peer review system, supports writing practice, particularly for large content courses in which writing is considered critical but not feasibly included. To help students gain content knowledge as well as writing and reviewing skills, SWoRD supports the whole cycle of writing, reviews, back-reviews, and rewriting by scaffolding the journal publication process as its authentic practice model. In addition, SWoRD includes algorithms that compute individual reviewer’s review accuracy, which is in turn used to support the various drawbacks of reciprocal peer reviews (e.g., variation in motivation or ability of reviewers). Finally, this paper describes an empirical evaluation showing that the SWoRD approach is effective in improving writing quality in content classes.     

Review of The mind’s we: Contextualism in cognitive psychology.

Reviews the book, The mind's we: Contextualism in cognitive psychology by Diane Gillespie (1992). In this text the author has both expanded on several of the key insights previously outlined in the critical literature and provided a congenial introductory text for the newcomer; a text to serve as a conceptual bridge between traditional cognitive psychological approaches and their newly emergent contextualist alternatives. As stated in her preface, Gillespie's purpose in preparing this book was to "bring together the work of psychologists who are interested in telling the contextualist story of cognition" and to "reveal and strengthen their insights and perspectives" (p. xiv). Given the philosophical range and theoretical diversity of those interested in telling such a story, the task is certainly a formidable one, but it is nonetheless one that she accomplishes with a commendable degree of elegance. Gillespie clearly articulates the diverse work of a large number of psychological theorists into a coherent and meaningful account that will do much toward imposing order on a field that is, by its very nature, somewhat scattered and contentious. Each of the book's six chapters proceeds carefully through a detailed and representative historical and conceptual analysis of traditional mechanistic approaches to human cognition prior to advancing their contextualist critiques and alternatives. Through a systematic analysis of the manner in which this "contextualist story" has arisen within the mechanistic milieu of traditional scientific psychology, she is able to clarify both the implications and relative merits and liabilities of two, quite often antithetical, conceptualizations of human cognitive phenomena.

Undergraduate Summer Research in Structural Engineering

For the last seven years, a summer Research Experiences for Undergraduates site in structural engineering, funded by the National Science Foundation, has operated at the University of Alabama at Birmingham. During this time, 33 students from 22 colleges and universities have participated in the site. Participants are recruited nationally and have come from as far away as California and Puerto Rico. The program is intended to provide students interested in graduate studies with an introduction to research methods, and to provide students who will not continue their studies past a bachelor of science in civil engineering with a better understanding of how research provides the theoretical foundation of engineering practice. Students work individually with faculty on literature reviews, computer modeling, laboratory testing, and field research. Three students have researched structural failure case studies and the technical and ethical lessons to be learned from them. Participants also have the opportunity to tour construction sites and construction material manufacturers’ and fabricators’ facilities. During the past three years, an ethics seminar series has been added. At the end of the program, students prepare research papers and Web pages documenting their work and present their results to faculty, students, and other participants.     

Norman Joseph Slamecka (1928-2003).

Presents an obituary for Norman J. Slamecka (1928-2003). Slamecka and his wife Jan were killed suddenly in a pedestrian accident on August 2, 2003, in Lewes, Delaware. He was a Marine veteran of the Korean War, and after a few years of practice as a clinical psychologist for the Veterans Administration, he accepted a faculty position at the University of Vermont in Burlington. He then taught at the State University of New York at Buffalo for a short while before coming to the University of Toronto in 1970, where he remained until his retirement in 1994.
