Attention-deficit/hyperactivity disorder (ADHD) is associated with unexplained impairments on speeded naming of coloured stimuli. These deficits may reflect hypofunctioning retinal dopaminergic mechanisms impairing particularly blue-yellow colour discrimination. Colour perception and rapid colour naming ability were investigated in 14 children…

A group of 190 third through sixth graders were given either 6, 16, or 26 months of reading instruction with functional color components (FCC) of parts of words. Another 160 children in the same schools did not recieve FCC instruction. FCC brought about improvement in reading scores. Nondisability children showed greater improvement. (Author)

It was hypothesized that Piaget's argument on behalf of the reorganization of cognitive processes would gain empirical support from a color/form, matching similar objects problem for 52 6-year-olds from a variety of socioeconomic backgrounds. (Author/MS)

This research attempts to determine whether or not a relationship exists between personality variables and frequency with which specific-colored targets are hit. Addresses the question of the relationship between color and personality and if it manifests itself in a reaction to color when a gross motor skill is performed. (Author/RK)

Questions why teachers persist in using red-ink pencils to mark students' papers. Draws parallels between psychological impact of red ink and associations with blood, violence, and horror. (NEC)

Developmental color perception of 278 four- and eight-year-old Black and White children in three societies was examined in relation to the theories that proximity to the equator and that fundus pigmentation (as measured by skin color) reduce shortwave (blue-green) in comparison to long-wave perception. (Author/MP)

A discussion of Edwin Land's experiments with color images from black-and-white photographs. Information is presented for duplication of these experiments by the amateur photographer. (BB)

This article is concerned with the perceptual load in searching for a number of kinds of target which are presented for a fixed, short period of time. The aim is to establish data which any acceptable model of human information processing will need to fit. (Author)

Habituated 180 neonates to white lights of varying luminance and tested for recovery of habituation to green, yellow, or red lights varying in excitation purity. Found that newborns discriminated chromatic stimuli from white only when excitation purity exceeded levels much higher than those for adults. Results reinforce view that neonates' vision…

Used multiple-baseline design to assess the utility of presenting three types of cues when teaching an abstract concept such as colors to three children with autism: plain, label, and symbol. Found colors presented with cues were easier to learn than color without cues. Findings support the need for sensitivity for the highly individualized…

Discusses the mix of features in the learning environment that must be considered for adult learners: visual environment, acoustics, temperature, lighting design, and layout. Addresses the interplay of these features with the learner's behavior in the space. (Contains 41 references.) (SK)

Do readers encode the sequencing of consonant (C) and vowel (V) phonemes (skeletal structure) in printed words? The authors used the Stroop task to examine readers' sensitivity to skeletal structure. In Experiment 1, CVC nonwords (e.g., pof) facilitated the naming of colors with congruent frames (e.g., red, a CVC word) but not with incongruent…

Using surface colours as stimuli, the present research was aimed at the two following goals: (1) To determine the chromatic angles related to categorical effects type B-B (Bezold-Brucke). (2) To determine the colourimetric characteristics compatible with each Spanish colour basic category. To get these goals the full set of tiles included in the…

In adults, visual search for a colour target is facilitated if the target and distractors fall in different colour categories (e.g. Daoutis, Pilling, & Davies, in press). The present study explored category effects in children's colour search. The relationship between linguistic colour categories and perceptual categories was addressed by…
