Two science questions are answered: (1) How can someone have one brown eye and one blue eye?, and (2) Why are magnets attracted to some metals, but not all metals? It is very rare that a human will have two irises of different colors. This condition, heterochromia, can be a normal variant or the result of an ocular disease. Heterochromia can…

Viewing a distorted face induces large aftereffects in the appearance of an undistorted face. The authors examined the processes underlying this adaptation by comparing how selective the aftereffects are for different dimensions of the images including size, spatial frequency content, contrast, and color. Face aftereffects had weaker selectivity…

This paper is concerned with how we prioritize the selection of new objects in visual scenes. We present four experiments investigating the effects of distractor previews on visual search through new objects. Participants viewed a set of to-be-ignored nontargets, with the task being to search for a target in a second set, added to the first after…

We here describe a discrete trial, forced-choice, combined spontaneous preference and novelty preference technique. In this technique, spontaneous preferences and familiarized (postfamiliarization) preferences are measured with the same stimulus pairs under closely parallel conditions. A variety of systematic stimulus variations were used in…

The author of this article is continually trying to come up with interesting ways for beginning art students to put color theory into practice. This article describes a project that integrates new learning about color schemes with previously learned concepts such as observational contour drawing and abstraction and converting two-dimensional shape…

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…

This article introduces digital imaging, an Adobe Photoshop course at Shrewsbury High School in Shrewsbury, Massachusetts. Students are able to earn art credits to graduate by successfully completing the course. Digital imaging must cover art criteria as well as technical skills. The course begins with tutorials created by the instructor and other…

We have developed two kinds of optical experiments: color mixture and fluorescence, using mini-torches with light emitting diodes (LEDs) that emit three primary colors. Since the tools used in the experiments are simple and inexpensive, students can easily retry and develop the experiments by themselves. As well as giving an introduction to basic…

People are immersed in visual culture and, therefore, are usually not aware of how power and privilege are enacted and how they operate in works of art from past and present times. Two premises infuse individuals' thinking on visual culture. First, that an activity-based approach to its study seeks to recognize how power and privilege function in…

The course outline has been prepared as a meaningful and practical approach to color. Mastery of Sppeedball Pen Lettering is a prerequisite for entry into the course. The purpose of the course is to teach the student the practices, techniques, and technology necessary to acquire an understanding of the color phenomenon. Consisting of 45 clock…

A study investigated the reciprocal relationship between colors and semantic terms--just as certain semantic terms elicit thoughts of particular colors, so those colors may also elicit their reciprocal semantic terms. Twenty-six students were each shown 18 words: 3 each of bipolar pairs that expressed evaluation, activity, or potency. The students…

The advancement of microcomputer technology has reached the point where color monitors and color computer software are fast becoming the norm in our information society. Color is another channel for communication, and can be used for enhancement of both aesthetic characteristics and productivity. The advantage to the use of color for communication…

This study investigates the relation between cognitive tempo and color responding on the Rorschach. (DEP)
