Robust interference effects were found which declined with age. Manipulating discriminability of the relevant stimulus dimension resulted in large changes in sorting time, but interference effects did not vary with baseline difficulty. These results were interpreted as strongly supporting both an absolute decrement model and a developmental trend…

The effects of brain waves and alpha rhythms on attentiveness to visual stimuli are discussed, and preliminary research findings and research needs are considered in connection with measuring and training for attention. (LH)

Examined visual fixation in infants 6 months to 2 years old for fit with theory of attentional inertia. Found that fixations had lognormal distribution, heart rate decreased during a look, and heart rate returned to prestimulus levels immediately before look offset. Older children showed different looking patterns to two types of stimuli; younger…

Examinations of interference between verbal and visual materials in working memory have produced mixed results. If there is a central form of storage (e.g., the focus of attention; N. Cowan, 2001), then cross-domain interference should be obtained. The authors examined this question with a visual-array comparison task (S. J. Luck & E. K. Vogel,…

Four-, six- and eight-year-old children from an Evanston, Illinois school were the subjects for three experiments designed to evaluate the effects of color, complexity, movement, and incongruity on children's visual attention. Computer generated displays were used to: (1) assess developmental trends among the three age groups, (2) test a novel…

Three related experiments were conducted to investigate the effects of novel and familiar stimuli on infant attention. The procedure in each of the experiments was to place an infant before a matrix panel composed of six rows of six lights. Two patterns of lights were used to obtain the infants' fixation time: (1) a point pattern, a single…

Eight males with autism were required to shift attention between rapidly flashed targets alternating between left and right visual hemifields. When targets were separated by less than 700 ms, steady-state brain electrical response in both hemispheres was augmented and background EEG decreased for rightward shifts as compared with leftward shifts.…

Objective: Cognitive effects of stimulant medication were investigated in children with mental retardation (MR) and attention-deficit/hyperactivity disorder (ADHD). Method: Performance on tasks tapping sustained attention, visual and auditory selective attention, inhibition, and immediate memory was assessed for 24 children (mean age 10.9 years)…

Vigilance performance of twenty fourth-grade retarded readers was compared with that of twenty normal readers matched for age, sex, grade, and intelligence. (Authors)

This study replicated Daneman and Carpenter's finding that the reading span test, as a measure of working memory storage and process functions, is predictive of performance on standard reading comprehension tests. It showed that reading span is related to the ability to draw inferences from, integrate, and encode text information. (Author/PN)

A study consisting of two experiments attempted to further adapt the visual preference procedure for determining children's meaningful phonological perception. In the first experiment, 1-year-olds were presented with auditory stimuli (words) and screens containing paired color photographs of the object described by each word and of an unusual…

The research in this article focuses on the relation between self-report of attention deficit disorder (ADD) symptoms and performance on a two-alternative forced-choice task that measures repetition effects. The ADD/Hyperactive Adolescent Self-Report Scale--Short Form is administered to college students after they completed the repetition effects…

Of particular interest in this study exploring a number of questions related to multi-image presentation of information and acquisition of a concept--e.g., classifying plants--was whether redundancy (i.e., additional positive examples) and an opportunity to view nonexamples as well as examples would be helpful to seventh-grade students.…
