A study to determine whether the differential development of conceptual tempo can predict preferences. Conceptual tempo predicted preferences in color-form sorting among 67 children ranging in age from 44 to 65 months. (WY)

Results demonstrate that number can be abstracted from an array of elements in estimating. Estimation appears to be based on the perception of a higher order structure, and persons of 8 years and older are able to abstract the structure from an array of objects. Even 6-year-old children can be trained to estimate by abstracting number. (Author/RH)

Two experiments were conducted to evaluate the relative efficiency of verbal and visual adjunct aids for concrete and abstract prose learning. For the abstract passage, verbal aids worked best and visual aids were somewhat disruptive. The concrete passage did not demonstrate the equivalency for two types of aids. (Author/PN)

Three experiments employed rectangles in stimulus identification tasks. It was concluded that the initial perceptual processing of rectangles is accomplished by separate dimensional analyzers operating in parallel. Observers adopt different decision strategies for negatively correlated sets and for single dimension sets when the number of…

Tested 61 randomly selected college students to determine whether methodologies employed in psycholinguistic investigation of sentence perception can be used to ascertain how screen media communicate. The paralinguistic techniques were not transferable to the examination of visual perception. More than 60 references are listed. (FM)

Intraperceptual theories of attention allow for the selective modulation of amount of nonconscious, perceptual processing of concurrent stimuli. Previous research is inconclusive because of the lack of an appropriate measure of perceptual processing. This experiment provides such a measure. The data support a broad version of intraperceptual…

Five experiments are reported concerning the effect on visual information processing of concurrently maintaining verbal information. The results suggest that the left cerebral hemisphere functions as a typical limited-capacity information processing system that can be influenced somewhat separately from the right hemisphere system.

This paper makes a start in the search for a fair test of prelingually deaf children's short-term visual memory ability by exploring the coding problems presented to them by the traditional digit-span test. It suggests that more research be devoted to the problem of stimulus-response compatibility. (Suthor/SJL)

No age differences were found in recall accuracy, types of errors, or introspective reports describing perceived recall strategies. Subjects were 8-, 12-, and 21-year-olds. These findings suggest even the eight-year-olds were able to employ a visual code and to retain it for several seconds in a situation in which incentive to do so was provided.…

Results indicated the following: unitary stimuli were easier to encode; partitioned stimuli were easier to recode; recoding was much more difficult than encoding; extended training improved performance; second graders were slightly better at encoding and much better at recoding than were kindergarten children. (Author/DB)

The ability of young infants between the ages of 8 and 17 weeks to perceive outline shapes was investigated in nine experiments using an habituation paradigm. (JMB)

Examined infants' use of configural and physical knowledge in segregating three-dimensional adjacent displays. Found that infants do use configural knowledge: they expect similar parts to belong to same unit and dissimilar parts to belong to distinct units. Also found that physical knowledge, such as impenetrability and support, influences their…

In order to shed light on the needs of children with cortical visual impairments, normal visual development of infants is described. Infant preferences for motion, faces, and black-and-white patterns are explained. Colors useful in stimulating vision development and the time needed for exposure to visual stimuli are discussed. (CR)
