Individuals are typically more likely to continue to interact with people if they have a positive impression of them. This article shows how this sequential sampling feature of impression formation can explain several biases in impression formation. The underlying mechanism is the sample bias generated when the probability of interaction depends…

This paper is a reflection on a three-year longitudinal study that explored the development of children's concept of a substance, for which detailed results concerning children's understandings have been reported elsewhere. The attention in this paper is on the methodological features related to the longitudinal nature of the study and the…

The correction for attenuation due to measurement error (CAME) has received many historical criticisms, most of which can be traced to the limited ability to use CAME inferentially. Past attempts to determine confidence intervals for CAME are summarized and their limitations discussed. The author suggests that inference requires confidence sets…

This article provides a science lesson for the middle school level, the metric system is used for all methods of measurement. The example lesson utilizes edible fruit as the real-world focus and offers ideas for additional lessons and the integration of disciplines beyond mathematics. This lesson requires students to handle, examine, and possibly…

The persistence of students' misconceptions about motion illustrates the enormous difficulty that teachers face in their attempts to overcome these with traditional physics instruction. An understanding of students' ideas about motion and ways to incorporate them into successful instructional approaches can be obtained from an analysis of…

How do people face the persistent movement in the present historical moment toward Empire and the curriculum of Empire? Hardt & Negri define Empire as the political subject that effectively regulates global exchanges, the sovereign power that governs the world. As Empire develops out goes national sovereignty, in comes supranational governance,…

The notions of "abstract "and "concrete" are central to the conceptualization of mathematical knowing and learning. It is generally accepted that development goes from concrete toward the abstract; but dialectical theorists maintain just the opposite: development consists of an ascension from the abstract to the concrete. In this article, we…

Previous research into children's concepts of peace, war and strategies to attain peace suggests that peace and war are developmentally constructed concepts. In order to examine the impact of the immediate sociocultural context, 343 adolescents in Northern Ireland in 2002 were questioned about their concepts of war and peace, and their strategies…

The study was aimed at characterizing the exact algebraic structure of the love schema in order to trace possible changes in the conceptualization of love throughout the adult life cycle, notably as regards the weight attributed to the three components of love: passion, intimacy, and commitment. The methodological framework was the Functional…

Modularity has been the subject of intense debate in the cognitive sciences for more than 2 decades. In some cases, misunderstandings have impeded conceptual progress. Here the authors identify arguments about modularity that either have been abandoned or were never held by proponents of modular views of the mind. The authors review arguments that…

This article focuses on traditional vocabulary instruction that has often had pernicious side effects: drill and kill that turned kids off to reading and word study. This trend can be reversed through careful attention to the needs and predilections of students as well as conspicuous consideration of the ramifications of time-cost. Here, the…

Object substitution masking (OSM) is said to occur when a perceptual object is hypothesized that is mismatched by subsequent sensory evidence, leading to a new hypothesized object being substituted for the first. For example, when a brief target is accompanied by a longer lasting display of nonoverlapping mask elements, reporting of target…

This article discusses creative writing which promotes literacy and content learning in a social studies classroom. In this article, the author states, that educators must encourage students' creative energies and enable them to engage with content in new and stimulating ways. One way to help students really learn about the concepts inherent in…

The main focus of this paper is on the study of students' conceptual understanding of two major concepts of Set Theory--the concepts of inclusion and belonging. To do so, we analyze two experimental classroom episodes. Our analysis rests on the theoretical idea that, from an ontogenetic viewpoint, the cognitive activity of representation of…

A 3-by-5 card is used to represent two or more sets of parallel lines, four right angles, opposite sides congruent and to investigate the Pythagorean theorem, similar triangles, and the tangent ratio before the introduction of computers. Students were asked to draw two parallel lines, cross them with a transversal and label the angles, which…
