A THEORY OF STRUCTURE IS ESSENTIAL TO AN OBJECTIVE ORGANIZATION OF BASIC PEDAGOGIES IN DESIGN. THE PURPOSE OF THIS STUDY WAS TO ASSESS THE STRUCTURAL THEORY OF MATHEMATICIAN K.L. WOLF AND TO TRANSLATE THIS THEORY INTO A VISUAL PRODUCT THAT COULD BE USED BY BEGINNING DESIGN STUDENTS. WOLF DESCRIBES 6 ISOMORPHIC COVERAGE OPERATIONS AND 7…

VISUAL TRAINING IS DEFINED AS THE FIELD OF OCULAR REEDUCATION AND REHABILITATION OF THE VARIOUS VISUAL SKILLS THAT ARE OF PARAMOUNT IMPORTANCE TO SCHOOL ACHIEVEMENT, AUTOMOBILE DRIVING, OUTDOOR SPORTS ACTIVITIES, AND OCCUPATIONAL PURSUITS. A HISTORY OF ORTHOPTICS, THE SUGGESTED NAME FOR THE ENTIRE FIELD OF OCULAR REEDUCATION, IS GIVEN. READING AS…

The ability of 50 lower middle-class and 25 upper middle-class prereading children to discriminate between pairs of uppercase alphabet letters was tested. A set of 3x5 cards with a sample stimulus in the upper center section of each card and two alternative choice stimuli just below and to the right and left of the sample was used. The 650 total…

This paper describes the physiological "eye noise" effect of line contrast in maps and considers the effect of line contrast on the direct picture of terrain surface as produced by shaded relief. An attempt is made to describe map reading in its two major steps: 1) the enrichment of the brain image resulting from scanning the map sheet,…

Elementary school students and adults were presented with a paired comparison task of visual complexity in which contour and presence or absence of structure in the patterns were manipulated. Results indicated that complexity judgments of all subjects were affected by the presence of structure at lower levels of contour. (GO)

Adult subjects viewed pictures at brief intervals, testing their reactions to informative objects--those not redundant with or predictive of the rest of the picture, such as a tractor in an underwater scene. Results indicated that observers fixate earlier, more often, and longer on informative objects. (Author/SJL)

This study investigated 17-week-old infants' response to discrepancy in visual patterns as a function of rate of habituation. (BRT)

Presents the results of investigating mature readers' focal points when viewing letters, words, and phrases. Several hypotheses from the experiments imply subconscious preprocessing for the mature reader. (JM)

Investigates whether tactual habituation without the assistance of vision occurs in four- to six-month-old infants. Additionally tests the relevance of a habituation/reaction to novelty procedure in the tactual modality. Results show clearly that tactual habituation occurs in such infants, just as visual habituation does. (Author/RH)

In three experiments, the effect of additional "contextual" elements on the discrimination of the orientation of linear and curvilinear segments was investigated with four-month-old infants. Results suggest that, regarding certain stimuli and techniques of measurement, surrounding contextual segments can aid the discrimination of linear…

In Experiment 1, the illumination of black stimuli on white backgrounds failed to facilitate discrimination learning. In Experiment 2, however, illumination of white stimuli on black backgrounds facilitated discrimination learning. Findings supported the use of changes in illumination as an attention-influencing feature of nonspeech communication…

Investigates preschool children's ability (n = 30) to discriminate age, and subject's use of different facial areas in ranking facial photographs into age order. Results indicate subjects from 3 to 9 years can successfully rank the photos. Compared with other facial features, the eye region was most important for success in the age ranking task.…

The ability of 3-month-old infants to discriminate novel components of a pre-familiarized stimulus was assessed using an operant paradigm. Subjects were 20 infants; adult judgments were taken from 15 college students. (Author/JH)
