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)

Kowalski and Zimiles (2006) and O'Hanlon and Roberson (2006) address an age-old question: Why do children find it difficult to learn color terms? Here these articles are reflected on, providing a focused examination of the issues central to this question. First, the criteria by which children are said to find color naming difficult are considered.…

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…

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…

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…

Describes the three part system of human vision. Explores the anatomical arrangement of the vision system from the eyes to the brain. Traces the path of various visual signals to their interpretations by the brain. Discusses human visual perception and its implications in art and design. (CW)

This study investigated the ability of first-, third-, and fifth-grade students to perceive similarities and differences in contour and interior pattern of shapes in color drawings. Results showed that with increase of age, attention to contour information was significantly affected by the surrounding contextual information found in the drawings.…

Article describes the advantages of bringing animals into the art room. (RK)

This study found that color in a film helped fourth- and fifth-grade students of all ability levels learn incidental information, but affected learning of task-relevant information differently depending on ability level. (Author/JEG)
