A version of the paper was presented at the American Association on Mental Deficiency (Boston, May, 1968). (JM)

Investigates infants' scanning of two compound stimuli by presenting features (either squares or faces) inside a frame, the frame alone, and features alone. The apparent disappearance of external bias at about 21 months appears to apply to the scanning of only some compound figures. For schematic face figures, no external bias was found.…

A taxonomy of visual attention influencing devices for mentally retarded children is presented. Five studies involving educable mentally retarded students (primary-middle school) are discussed which identified motion, verbal pointers, arrows, and spatial location as the most effective attention influencing devices. Results had implications for…

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)

Using an objective measure of attention obtained during a baseline period, assesses in two studies the effects of attention on operant learning among 240 infants 14 weeks of age who were rewarded for kicking with a pattern of lights and tones. (RH)

Examines periods of mutual gaze and visual coorientation between mothers and their two- to four-month-old infants as contexts for the utilization of maternal verbal control techniques. Additional questions involve the impact of infant sex and maternal sensitivity upon the utilization of these techniques. (Author/MP)

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)

The hypothesis was that the two hemispheres have different functions in normal vision, the dominant one analyzing the "figure," and the nondominant the "background." The investigation examined responses of 41 female psychology students. Results were consistent with the hypothesis. (Author/RD)

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…

Research results show that it may be possible, within limitations, to facilitate discrimination by infants of inappropriate from appropriate verbal descriptions of a visual event, by emphasizing the agent component in a simple sentence. (Author/JB)

The second in a series that discusses effective approaches to presenting information, this article examines six guidelines useful for translating a script into a memorable film or tape. Six references are cited. (Author/MER)
