The purpose of this study was to investigate the development of organizational processes for both verbal and spatial stimulus materials within an information processing framework. Children in grades 2 and 4 and adults were tested for their ability to report letter strings reflecting various orders of approximation to English and various dot…

The purpose of this study was to examine the relationship between the various techniques used to estimate the time required by the human to process a visual stimuli, i.e., recognize a stimulus input into the visual perceptual system. Sixteen tests of visual processing speed were administered to 110 undergraduate students. In summary, scores tended…

A computer-based Eye-Movement Controlled Display System was developed for the study of perceptual processes in reading. Studies were conducted to identify the region from which skilled readers pick up various types of visual information during a fixation while reading. The results indicated that the subjects acquired word length pattern…

An experiment was conducted to determine the influence of three variables on the perception of the psychophysical phenomenon of flicker in wide angle cathode ray tube (CRT) displays. The three independent variables treated in the experiment were: 3, 6, and 9 foot-lambers (FL) illumination levels; four images, three static and one dynamic; and 26…

Three forms of a symbol-digit substitution task were administered to 62 female and 96 male college students. Results support the theory that the superior performance of women over men on the Digit-Symbol Substituion subtest of the Wechsler scales is due to their greater ability to encode symbols verbally.

Describes ways for developing visual imagery in the early childhood education program, preparing children for discrimination learning and reading instruction. (RL)

Studies the ability of 5-month-old infants to recall temporal information and use temporal organization by training them to fixate a hierarchically structured or unstructured sequence of stimuli which appeared in four spatial positions. Results are interpreted within a temporal organizational framework; infants appear to use organization within…

An attempt to isolate possible effects of the application of visual reminders on learning by TV. The underlying assumption was that learning by means of television and other visual media can be enhanced by methodically applying visual reminders. (Author)

Reviews a large number of studies of eye movement. Bibliography appended. (LS)

Focuses on the differential representation of mental functions between the two human cerebral hemispheres. The manner in which right hemisphere function laterizes in childhood was studied in 98 five- to twelve-year-old children. (CM)

Outlines a concentrated in-service visual training program which incorporates (1) perceptual effects of visual stimuli, (2) synthetic and natural stimuli, (3) non-verbal stimuli, (4) pictorial communication, (5) visual persuasion, and (6) creative visualization. (Author/CMV)

Tested the hypotheses that errors of ommission would occur more frequently than errors of commission and errors would be related to stimulus complexity. A total of 48 children from grades 1 and 3 were given a memory task (involving visual and haptic memory) for recognition of random polygons. (MS)

This investigation with 122 college students, including 45 deaf students, found that neither deaf nor hearing students demonstrated a statistically significant advantage in accuracy or recall of nonverbal information about people in photographs. Deaf subjects, however, were more than twice as likely as hearing subjects to base their judgments upon…
