Tests the hypothesis that age-related shifts in infants' visual preferences for stimuli (varying in complexity as defined by number of light-dark intersections) are due to changing attention value both within and between the inversely varying dimensions of size and number. (Author/ED)

This experiment attempted to obtain an estimate of perceptual isolation effects when the isolated item was the only distinctive feature in the list and to obtain data on continuous serial learning in order that isolation and serial-position effects could be compared directly. (Author/RK)

A DOCTORAL DISSERTATION WHICH EXPLORES THE CLASSICAL THEORY OF PERCEPTION IN READING IS REPORTED. THE FACTS REPORTED IN PERCEPTUAL RESEARCH ARE REALIGNED IN TERMS OF CERTAIN PREMISES OF GENERAL OPEN SYSTEMS THEORY AS UTILIZED BY THE SUBSTRATA-FACTOR THEORY AND THE PARTICULAR POINT OF VIEW OF THE INFORMATION THEORIST BROADBENT TO PRODUCE A NEW…

THE IMPORTANCE OF ILLUMINATION TO THE SCHOOL CHILD IS DISCUSSED. VISUAL EFFICIENCY HAS A MARKED EFFECT UPON MANY LEARNING SITUATIONS AND IT IS INFLUENCED BY A NUMBER OF FACTORS--(1) THE STAGE OF GROWTH AND DEVELOPMENT OF THE CHILD'S EYES, (2) THE PRESENCE OF EYE DEFECTS, (3) RELATIVE BRIGHTNESS OF OBJECT AND BACKGROUND (CONTRAST), (4) SIZE OF…

The study undertakes to clarify and redefine some of the concepts underlying the relations between visual perception and thinking. A sample bibliography suggests sources for future research. Psychological and psysiological theory is shown historically to have separated the two mental functions in principle. Correspondingly, present-day education,…

A study was conducted with three eighth grade students to determine the separate and joint effects of image size, image brightness, and image contrast on the visibility of projected materials. Twenty-five hundred slides were presented, representing 20 slides each of all possible combinations of values of the independent variables. Telegraph keys…

In the three studies reported here, an attempt was made to determine whether adult native speakers of English can agree on the choice of phonetic labels for visually presented geometric figures. It was the purpose of these studies to obtain evidence in support of the "phonetic symbolism" hypothesis. An initial study and two replications…

Previous work shows that skilled college level readers tend to apprehend words as wholes, whereas they tend to process random strings of letters as a series of individual letters. Subjects in the study were forced to process words and non-word strings both serially and under conditions which allowed simultaneous processing, and their performances…

The raw data collected in a study to determine the effect of attention in measuring visual perception are provided. A key to the 19 numerical headings of the raw data tabulation is given. Two pages of tables presented the raw data. (For related documents, see TM 002 116,117.) (DJ)

Two experiments examined the effect of haptic exploration on visual recognition of nonsense forms by 4- to 7-year-old children. In Experiment 1, haptic activity was optional for S. The amount and type of activity was rated. Those Ss who voluntarily produced haptic activity reached criterion in a repeated exposure-test recognition task in fewer…
