Instructions are given for building physical scale models of ordered structures of B-form DNA, protein [alpha]-helix, and parallel and antiparallel protein [beta]-pleated sheets made from colored computer printouts designed for transparency film sheets. Cut-outs from these sheets are easily assembled. Conventional color coding for atoms are used…

Both classical and recent reports suggest a right-hemisphere superiority for color discrimination. Testing highly-trained normal subjects and taking care to eliminate asymmetries from the testing situation, we found no significant differences between left and right hemifields or between upper and lower hemifields. This was the case for both of the…

We present data indicating that visual awareness for a basic perceptual feature (colour) can be influenced by the relation between the feature and the semantic properties of the stimulus. We examined semantic interference from the meaning of a colour word ("RED") on simple colour (ink related) detection responses in a patient with simultagnosia…

An activity has been designed for the purpose of teaching how light is dispersed in a straight line and about the interaction between matter and light as well as the related concepts of shadows, partial shadows, reflection, refraction, primary colours and complementary (secondary) colours, and differentiating the relationship between colours, all…

Along with inquiry-based teaching, exploring the elements of art can guide students to view and represent objects realistically. Understanding line, shape, color, value, form, space, and texture helps bridge the gap between what students actually observe and what their preconceived ideas about the object may be. This type of explicit instruction…

Past research suggests that both White children and minority children, including Hispanics, hold pro-White biases. Although doll studies have been a popular way of assessing racial attitudes among children, several methodological issues have made it challenging to interpret the results from these studies. Furthermore, past research has failed to…

Six pigeons were trained in a delayed matching-to-sample task involving bright- and dim-yellow samples on a central key, a five-peck response requirement to either sample, a constant 1.5-s delay, and the presentation of comparison stimuli composed of red on the left key and green on the right key or vice versa. Green-key responses were…

Paul Klee's "Caprice in February" was on display in the author's artroom for use with a third-grade class. Without any prompting, her kindergartners became very interested in the color of his background. The author decided to take advantage of her students' enthusiasm. This article presents how the author and her kindergarten class use "Caprice in…

A sparse mask that persists beyond the duration of a target can reduce its visibility, a phenomenon called "object substitution masking". Y. Jiang and M. M. Chun (2001a) found an asymmetric pattern of substitution masking such that a mask on the peripheral side of the target caused stronger substitution masking than on the central side.…

Vantage Theory (VT) and Cognitive Grammar (CG) both rely crucially on the cognitive phenomenon of categorization as well as on the semantic/pragmatic notion of participant point of view in making claims about human linguistic production and perception. In this paper these commonalities of commitment are explored, as are the differences in the ways…

The Polish set of terms for blue includes, inter alia, the following adjectives: "niebieski" "blue", "blekitny" "(sky) blue", "granatowy" "navy blue", "lazurowy" "azure", "modry" "(intense) blue" and "siny" "(grey) violet-blue". The adjective "niebieski" is the basic term; however, it shares some of its functions with "blekitny", which is…

The central claim of this paper is that Vantage Theory is able to provide a much-needed explanatory account of the seemingly unrelated differences between lexical and morphological antonyms of dimensional adjectives in Slavic languages. In a case study, I compare two antonyms of the Russian adjective "vysokij" "high", a morphologically unrelated…

English teachers have a unique opportunity to expand and develop the way their students think. Too often, students are comfortable in thinking about reading and writing processes in a concrete or linear way. They are used to "right" or "wrong" answers in their other studies and look for the same in their English assignments. While teachers often…

The theory of constructive operators was used as a framework to design two versions of a paradigm (color matching task, CMT) in which items are parametrically ordered in difficulty, and differ only contextually. Items in CMT-Balloon are facilitating, whereas items in CMT-Clown contain misleading cues. Participants of ages 7-14 years and adults (N…

Behavioral studies indicate that subjects are able to divide attention between multiple streams of information at different locations. However, it is still unclear to what extent the observed costs reflect processes specifically associated with spatial attention, versus more general interference due the concurrent monitoring of multiple streams of…
