Genetics is often a fascinating but difficult subject for middle level students. They can see the results of genes in every organism, but trying to visualize what happens at the level of genes is challenging for concrete thinkers. The author discusses an approach that helps students understand how genotypes can translate into phenotypes, then…

Selections of liquid aldehydes and ketones are proposed for students to determine what property is the best predictor of the color (yellow to red) of their 2,4-dinitrophenylhydrazone derivative. Students may use a computer (spreadsheet or word processor) to analyze results. (Contains 1 table and 3 notes.)

Stroop dilution is the reduction of the Stroop effect in the presence of a neutral word. It has been attributed to competition for attention between the color word and neutral word, to competition between all stimuli in the visual field, and to perceptual interference. Five experiments tested these accounts. The critical manipulation was whether…

Ninety-six participants, who were younger (20 years) or older (68 years) adults and either monolingual or bilingual, completed tasks assessing working memory, lexical retrieval, and executive control. Younger participants performed most of the tasks better than older participants, confirming the effect of aging on these processes. The effect of…

CHROMACODE is a conceptual tool that uses systematic, logical, and visual processes for organizing and analyzing qualitative research findings for the researcher with relatively low technical knowledge of data analysis. It can best be described as a visual conceptual scheme with coding based on a color-dependent procedure. Color provides a sense…

Dyes aren't just for fabrics--colorants have been added to food for centuries to enhance its appearance. This monograph and teaching guide investigates both the compounds that give foods their natural color and synthetic colorants currently approved for use in foods. Problem-solving inquiry based activities involve high school level students in…

This paper explores the long-term effects of assigning cultural symbols to one's natural sensory experiences. Sixty-two Washington State residents of differing occupations, ages 16-51, participated in the study. Participants' responses to the question, "When did you first learn the color green?" fell into two main categories. Some…

The interaction between field dependence/independence and pictorial recognition memory was investigated using pictures in three different color modes: realistic color, non-realistic color, and black and white. The study was designed to further confirm the efficacy of applying signal detection analyses to color recognition memory data as a means of…

The article compares student preferences for recreational sites when viewing color slide presentations as compared to on-site evaluation. (CD)

The author fantasizes that at some point in the distant past England was a Spanish colony. He supports his thesis by revealing fantastic etymologies of some English place names showing the influence of Spanish on English, for example "Surrey" comes from "su rey." (Text is in Spanish.) (TL)

A week after the 9/11 WTC event, the collage project that Nell Ruby and her class had been working on in a basic design classroom lacked relevance. They had been working from master works, analyzing hue and value relationships, color schemes, shape, and composition. The master works seemed unimportant because of the immense emotional impact of the…

Two studies investigated (1) the art preference of young children for realistic, stylized, and abstract styles, and (2) the influence exposure to art had on style preferences. In the first study, 41 preschool children were individually administered an art style preference task comprised of 9 prints, 3 of each style, of well-known paintings. Color…

The relationship between age of onset of blindness and development of knowledge of color relations was examined with 16 college students who had been born totally blind, 16 who had been blinded totally at approximately 15 years of age, and 16 who had normal vision. Ss were asked to judge the similarities between color names, and judgments were…

The purpose of this study was to determine what effect, if any, color has on the young child's perception of apparent weight. (Author)

A study was conducted to determine if there was a relationship between the cognitive styles of learners and their ability to correctly identify previously seen pictorial materials presented in color or black and white. Fifty-three third and fourth grade students from the Pittsburgh Public School System served as subjects for the study. Testing…
