This article examines how material objects such as photographs, papers and computers influence documentation practices in a Swedish preschool. The importance of teacher documentation is emphasized in the 2010 revised Swedish preschool curriculum as a means of evaluating preschool quality. However, the curriculum gives no specific guidelines about…

Multimodal approaches have been shown to be effective for many learning tasks. In this study, we compared the effectiveness of five multimodal methods for second language (L2) Mandarin tone perception training: three single-cue methods (number, pitch contour, color) and two dual-cue methods (color and number, color and pitch contour). A total of…

This study investigates language-promoting strategies and support of concept development displayed by preschool staffs' when interacting with preschool children in literacy-related play activities. The data analysed consisted of 39 minutes of video, selected systematically from a total of 11 hours of video material from six Swedish preschool…

In this article we propose an activity aimed at introductory students to help them understand the Stefan-Boltzmann and Wien's displacement laws. It only requires simple materials that are available at any school: an incandescent lamp, a variable dc energy supply, and a computer to run an interactive simulation of the blackbody spectrum.…

Even an irrelevant distractor stimulus is integrated into event files. Subsequently repeating the distractor triggers retrieval of the event file; however, an unresolved issue concerns the question of "what" is retrieved by the distractor. While recent studies predominantly assume that the distractor retrieves the previous response, it…

This study aimed to compare children's performance on two mnemonic functions that engage the lateral prefrontal cortex. Brain imaging studies in adults have shown that the mid-ventrolateral prefrontal cortex is specifically involved in active controlled retrieval, and the mid-dorsolateral prefrontal cortex is specifically involved in monitoring…

This dissertation explores the main question, "What are the issues involved in the definition and translation of color terms in dictionaries?" To answer this question, I examined color term definitions in monolingual dictionaries of French and English, and color term translations in bilingual dictionaries of French paired with nine…

The psychological literature on colorism, a form of within-group racial discrimination, is sparse. In an effort to contribute to this understudied area and highlight its significance, a concise and selective review of the history of colorism in Latin America is provided. Specifically, three historical eras (i.e., conquest, colonization, and…

We examined categorical effects in color appearance in two tasks, which in part differed in the extent to which color naming was explicitly required for the response. In one, we measured the effects of color differences on perceptual grouping for hues that spanned the blue-green boundary, to test whether chromatic differences across the boundary…

This study investigates to what extent the amount of variation in a visual scene causes speakers to mention the attribute color in their definite target descriptions, focusing on scenes in which this attribute is not needed for identification of the target. The results of our three experiments show that speakers are more likely to redundantly…

Binary-choice reactions are typically faster when the stimulus location corresponds with that of the response than when it does not. This advantage of spatial correspondence is known as the "stimulus-response compatibility" (SRC) effect when the mapping of stimulus location, as the relevant stimulus dimension, is varied to be compatible or…

The pattern of shading across an image can provide a rich sense of object shape. Our ability to use shading information is remarkable given the infinite possible combinations of illumination, shape and reflectance that could have produced any given image. Illumination can change dramatically across environments (e.g. indoor vs. outdoor) and times…

Despite the growing numbers of migrant students enrolling in Australian secondary schools, and an official acknowledgment of their complex support and learning needs, there has been little policy focus on the pedagogical changes that need to be made by teachers to accommodate these needs. There is also little understanding of the depth and…

Chemical kinetic experiments to determine rate laws are common in high school and college chemistry courses. For reactions involving a color change, rate laws can be determined experimentally using spectrophotometric or colorimetric equipment though this equipment can be cost prohibitive. Previous work demonstrated that inexpensive handheld camera…

As teachers seek activities to assist students in understanding division as more than just the algorithm, they find many examples of division as fair sharing. However, teachers have few activities to engage students in a quotative (measurement) model of division. Efraim Fischbein and his colleagues (1985) defined two types of whole-number…
