Used shift-rate recovery method in three experiments to examine extent to which 6-month-olds find perceptual cues such as density and length useful in discrimination of linearly arranged sets of large numbers of objects. Found that infants can discriminate between large number sets by relying on absolute cues such as density and on relative cues…

The eugenics era (c. 1900?1930) produced a strong desire among mental retardation professionals to recognize and control "the feeble-minded." Some eugenicists believed it was possible to classify individuals visually by learning to recognize what they believed to be observable characteristics of idiocy and imbecility. In this paper I used…

This article examines how the human visual system represents the shapes of 3-dimensional (3D) objects. One long-standing hypothesis is that object shapes are represented in terms of volumetric component parts and their spatial configuration. This hypothesis is examined in 3 experiments using a whole-part matching paradigm in which participants…

Recent visual marking studies have shown that the carry-over of distractor inhibition can impair the ability of singletons to capture attention if the singleton and distractors share features. The current study extends this finding to first-order motion targets and distractors, clearly separated in time by a visual cue (the letter X). Target…

The focus of this study was on the visual analysis of time series data for evaluating educational programs. Two characteristics of the data--changes in slope and variability--and two characteristics of evaluation--training in data utilization and the use of aimlines/decision rules--were manipulated. A total of 51 students and/or teachers in…

The question studied whether the specific seven TICCIT system colors used within color coding schemes can be a source of confusion, or not seen at all, by the color-blind segment of target populations. Subjects were 11 color-blind and three normally sighted students at Brigham Young University. After a preliminary training exercise to acquaint the…

The relationship of astigmatism to reading and the possible detrimental effects it might have on reading were investigated. The greatest incidence of astigmatism was for the with-the-rule type ranging from .50 to 1.00 diopter. This type of astigmatism was induced in 35 seniors from the Los Angeles College of Optometry by placing cylindrical lenses…

In an earlier study, subjects who were shown the two words "inside" and "consult" at two different points in a study list of two syllable words were willing to accept the word "insult" as having been on the study list. It was concluded that each syllable had a representation in memory over and beyond the semantic factors which are normally…

Little research has been done to explain just why words are recognized more easily than letters alone; although, this phenomenon has been accepted widely by educators. Therefore, a model of the processes involved in word recognition and suggestions concerning how these processes can be put to use in reading instruction are presented. The model…

A research project investigated the extent to which children's visual awareness and visual literacy were developed through photography. Thirty-four elementary school students were provided with Polaroid "Big Swinger" cameras; they were given one roll of film per day for eight weeks and allowed to photograph whatever they liked. After…

A long-range investigation is being made to define the characteristics required of a television system to simulate a visual environment which will permit target acquisition performance comparable to that obtained in the real world. In this portion of the investigation, target recognition performance under direct viewing conditions was compared…

THE EFFECTS OF INSTRUCTIONS, TYPE OF LABEL, TYPE OF CONCEPT, AND SEQUENCE OF CONCEPTS BY TYPE UPON CONCEPT IDENTIFICATION WERE INVESTIGATED IN THIS STUDY. PERFORMANCE WAS ANALYZED IN TERMS OF FOUR TYPES OF TEST ITEMS. INSTRUCTION, FOCUSING ON THE CONCEPT TO BE ATTAINED AND THE CONCEPT NATURE, WAS FOUND TO FACILITATE CONCEPT IDENTIFICATION…

Twenty-eight kindergarten children (5-6 years old) were tested in order to identify children with learning disabilities and to compare tests results. (Author)

Early acquisition of right and left as absolute concepts does not seem to be related to early mastery of right and left as relative concepts among the Hausa. (Author)

A report and discussion is given of some of the results of testing students at the Papua New Guinea University of Technology on diagrams which involved the use of visual conventions. (MN)
