We compared the ability of auditory, visual, and audiovisual (bimodal) exogenous cues to capture visuo-spatial attention under conditions of no load versus high perceptual load. Participants had to discriminate the elevation (up vs. down) of visual targets preceded by either unimodal or bimodal cues under conditions of high perceptual load (in…

Three experiments involving 20 severely and profoundly mentally retarded adults revealed that redundant color cues did not facilitate visual discrimination of lexigrams, while random assignment of color and distinctive-feature training did facilitate visual discrimination. (CL)

THE PURPOSE OF THIS STUDY WAS TO DETERMINE THE RELATIVE INFLUENCE OF FIVE VARIABLES (INITIAL INSTRUCTIONS, REWARD, LETTER SIZE, TYPE OF WARM-UP, AND FEEDBACK) ON KINDERGARTEN CHILDREN'S PERFORMANCE OF A LETTER DISCRIMINATION TASK. IT HAS BEEN ARGUED THAT ATTENTION IS THE KEY FACTOR IN LETTER DISCRIMINATION. THE PRESENT STUDY PROPOSES THAT A…

In three experiments, nine-month-old infants were trained to fixate on a particular feature in a pair of stimuli that varied along three dimensions. In a fourth experiment, infants were trained to fixate on a stimulus compound until reaching a learning criterion. Infants' discrimination learning under these conditions implied an ability to attend…

This report summarizes research concerning stimulus analyzing mechanisms, giving the main experimental findings and theoretical developments. Most of the data and the experimental findings are to be found in the 89 publications listed in the bibliography. The research is discussed under five main headings: (1) shape recognition, (2) selective…

Investigates the dominance of global versus local visual properties in four-month-old infants as a function of individual differences in fixation duration. Suggests that long-looking infants process visual information more slowly than short-looking infants, and there may be qualitative differences in the manner in which the two groups of infants…

General intelligence may set structural feature limitations on three aspects of selective attention: direction, adjustability, and breadth. Data, theory, and methods bearing on this hypothesis were reviewed from the domain of visual discrimination learning. (Author/BW)

These guidelines are part of a total curricular program K-12 developed for use in the elementary and secondary schools of the Diocese of Cleveland. Objectives for the study of the communication arts in these grades are listed as follows: (1) Listening with attention, discrimination, and empathy, (2) Viewing with perception, discrimination, and…

This monograph is a collection of papers describing a series of loosely related studies of visual attention, auditory stimulation, and language discrimination in young infants. Titles include: (1) Infant Attention and Discrimination: Methodological and Substantive Issues; (2) The Addition of Auditory Stimulation (Music) and an Interspersed…
