Attempts to define "creative categorization" using animal behavior and human perception as examples. (RK)

Presents a multidisciplinary unit on natural dyes designed to take advantage of the natural curiosity of middle school students. Discusses history of dyes, natural dyes, preparation of dyes, and the dyeing process. (JRH)

The test-retest reliability of colored filter testing in relation to two symptom levels of dyslexia was evaluated using a forced-choice test procedure. Two tests, separated by two weeks, were conducted with 41 participants (ages 15 to 17). Results indicated poor test-retest reliability. (Author/DB)

Presents an explanation on subtractive and additive color processing using the colors yellow and pink as examples. (MVL)

Tests the effects that many photographers believe color and complexity have on how people process the information in photographs. Finds that images with color and more complex elements were easier to remember, and that complexity did not result in more (reported) mental effort. (SR)

Discusses the rapid changes in publishing, especially electronic publishing, and reviews current trends including digital imaging, PDF (portable document format), color production, and XML. Considers the perceived valuation of the electronic submission of academic work within higher education and the need to be lifelong learners, especially…

Examines the effects on mail survey response rates of variations in questionnaire color and format. States that a follow-up mail survey to a corporate incentive program was sent to more than 3,500 participants. Concludes that a user-friendly format as well as color variation was of value in increasing survey response rates. Discusses implications.…

Studied the structure of color cures that allows the express recognition of scene gists in 3 experiments involving 60 college students. Taken together, results suggest that colored blobs at a coarse spatial scale concur with luminance cues to form the relevant spatial layout that mediates express scene recognition. (SLD)

The question of innateness, which naturally arises in respect of the method of category construction proposed by vantage theory, is notoriously difficult. Discusses some of the problems inherent in this type of issue, along with attendant assumptions. Then, turns to what might constitute possible grounding for vantage theory. (Author/VWL)

The equilibrium phenomenon of matching behavior traditionally has been studied in stationary environments. Here we attempt to uncover the local mechanism of choice that gives rise to matching by studying behavior in a highly dynamic foraging environment. In our experiments, 2 rhesus monkeys ("Macacca mulatta") foraged for juice rewards by making…

In this article the author examines ways in which early childhood students can explore the building blocks of form to reveal meaningful content as exemplified in four Modernist works of art. Each piece reflects of the Modernist aesthetic, characterized by the simplification of visual elements into flat, bold colors and simplified geometric shapes.…

Eight experiments examined the conditions under which a color singleton that is presented for the 1st time without prior announcement captures attention. The main hypothesis is that an unannounced singleton captures attention to the extent that it deviates from expectations. This hypothesis was tested within a visual-search paradigm in which…

The study investigated the effects of music with high arousal potential and negative affect (HA), music with low arousal potential and positive affect (LA), and everyday noise, on the cognitive task performance of introverts and extraverts. Forty participants completed five cognitive tasks: immediate recall, free recall, numerical and delayed…

A laboratory exercise is presented in which students determine where metabolic heat is primarily generated in blooming eastern skunk cabbage ("Symplocarpus foetidus") plants. Students consider how color, shape, and orientation of spathes, and stage of flower maturation, may affect metabolic heat production and retention of both metabolic and solar…

We measured the increase in reading speed afforded by two currently available systems of coloured overlays: the "Intuitive Overlays," which provide a choice of 30 colours, and the "Eye Level Reading Rulers," which provide a choice of 5. Forty-eight pupils from a local authority primary school who reported experiencing symptoms of visual stress…
