Elucidates some aspects of Newton's theory of light and colors, specifically as presented in his first optical paper in 1672. Analyzes Newton's main experiments intended to show that light is a mixture of rays with different refrangibilities. (SAH)

Introduces this special issue of the journal, which focuses on vantage theory. Articles in this issue demonstrate applications of vantage theory across diverse realms of cognition. (Author/VWL)

If one looks at a rain cloud with the Sun behind one's back, the sunlight and water drops may interact just right, revealing the familiar arc of red, orange, yellow, green, blue, indigo, and violet. Many of people have been pleasantly surprised to see a rainbow in the sky, but probably have not considered why they occur. Rainbows are caused by…

The relative efficacy with which appearance of a new object orients visual attention was investigated. At issue is whether the visual system treats onset as being of particular importance or only 1 of a number of stimulus events equally likely to summon attention. Using the 1-shot change detection paradigm, the authors compared detectability of…

The perception of colour in an embedded field is affected by the surround colour. This phenomenon is known as chromatic induction. In the present study we investigated whether the colour perception by infants aged 5-7 months could be affected by the surround colour. In Experiments 1 and 2 each stimulus was composed of an array of six squares in…

Do the viewpoint costs incurred when naming rotated familiar objects arise during initial identification or during consolidation? To answer this question we employed an attentional blink (AB) task where two target objects appeared amongst a rapid stream of distractor objects. Our assumption was that while both targets and distractors undergo…

C. M. MacLeod and P. A. MacDonald (2000) suggested that congruent and incongruent Stroop stimuli cause more task conflict than neutral stimuli because the anterior cingulate cortex is more activated with these stimuli. This study investigated behavioral expression for this pattern. Experiment 1 reduced task conflict control by increasing the…

To circumvent the problem of academic dishonesty through the mass administration of multiple-choice exams in college classrooms, a study was conducted from 2003 to 2005, in which multiple versions of the same examination were color coded during testing in a large-enrollment classroom. Instructors reported that this color-coded exam system appeared…

Three experiments were carried out to investigate hemispheric asymmetry in color processing among normal participants. In Experiment 1, it was shown that the reaction times (RTs) of the dominant and non-dominant hands assessed using a visual target presented at the central visual field, were not significantly different. In Experiment 2, RTs of…

Purpose: This research examined how the color distribution of symbols within a visual aided augmentative and alternative communication array influenced the speed and accuracy with which participants with and without Down syndrome located a target picture symbol. Method: Eight typically developing children below the age of 4 years, 8 typically…

The color wheel, because it is an excellent way to teach color theory has become somewhat of a traditional assignment in most basic design courses. Article described a way to change this situation by re-designing and improving upon the basic color wheel. (Author/RK)

The process of making the buffalo hide into the buffalo robe, which was a very important article of clothing to the American Indian, is discussed. (NQ)

Focusing on the effects that color photography has had on the content of photographs published in daily newspapers in the United States, a study conducted interviews with both photographers and photo editors and also carried out a content analysis comparison of photographs published before and after the use of color at a small daily, "The…

Appropriate namings and selections of four focal hues and eight intermediate hues, and relationships between them, increase with the age of 3, 4 and 5-year-old nursery school children. (Author)
