A new type of DVD spectroscope, the periscope type, is described and the numerical analysis of the observed emission and absorption spectra is demonstrated. A small and thin mirror is put inside and an eighth part of a DVD is used as a grating. Using this improved DVD spectroscope, one can observe and photograph visible spectra more easily and…

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…

Discusses the ways in which color halftones can be used in campus newspapers to attract attention to ads, headlines, and editorial copy. Explains how to change the hue, value, and saturation of a color and the effects the changes should achieve. (AYC)

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…

In order to discover reader reactions to color on a newspaper page, specifically eye movement and overall opinion of the paper, identical pages were created and printed by the "St. Petersburg Times" (Florida). The content of fifteen front pages, six lifestyles pages, and three sports front pages were nearly identical, differing only in the kind…

Describes the advantages and problems of using new color printing technology in student newspapers. (CRH)

A discussion of the effect of background color on the legibility of projected printed messages on transparencies. (Author)

A presentation of some inexpensive ways to brighten up titles for color productions. (Author)

The classification and cataloging of slides pose unique and critical problems in every field where they are used. A brief overview of the literature is presented, along with observations on local area slide systems and a description of a slide system developed for use in C-E Refractories' Research and Development Library utilizing color…

Examined whether public relations and social psychology beliefs about color are adapatable to the market conditions of campaigns. Surveyed voters (N=273) incorporating relevant questions on legibility, preference, and remembrance of color patterns. One combination - black on yellow - was most legible, most preferred, and most remembered; blue…
