Ten mildly retarded young adult males and nonretarded subjects matched for chronological age or mental age were required to recognize both verbal and nonverbal stimuli presented tachistoscopically. Results of a backward visual masking paradigm varying stimulus onset asynchrony (SOA) indicated the retarded subjects performed poorer at the longest…

The reading comprehension of hyperlexic children, mentally retarded children who can read aloud written words better than one would expect from their Mental Age, was investigated in four experiments involving both autistic and nonautistic children. (Author/NH)

Describes preschool children's ability to simultaneously perceive multiple aspects of an object in two experiments during which three- to five-year-olds were asked to describe part/whole pictures. (HOD)

Measures the degree of interdependence in timing between infants' right and left arm movements and between movements of both arms and the onsets of stressed vowels in tape-recorded infant-appropriate speech. (HOD)

To explore the relationship between spatial ability and both image quality and image process efficiency, 79 subjects completed spatial tests, imagery questionnaires, and laboratory tasks. Laboratory measures of process efficiency and image quality were strongly related to spatial test performance and weakly related to one another. (Author/BW)

The degree to which concreteness of prose material presented in an auditory fashion would interact with learners' lateral preference under different right hemispheric presentation conditions was investigated with 96 adults. Subjects recalled a greater number of ideas when the passage was concrete. Abstractness interacted with cerebral dominance.…

A total of 15 learning-disabled and 15 skilled readers viewed three groups of nonsense pictures (unnamed, name-nonassociated, and name-associated), then recalled them later. Results suggested learning disabled children's reading difficulties are due to an inability to activate a semantic representation that interconnects visual and verbal codes.…

Third-grade, sixth-grade, and college-age subjects were asked to identify briefly presented words accompanied by either words or letter strings in the same or opposite hemifield. Results indicated two sources of visual field interference: one relating to the presence of alphanumeric information elsewhere in the visual field and the other…

A total of 630 boys and girls from kindergarten to second grade were asked to compare durations that differ in beginning times with those that differ in ending times. Possible sources of children's failure to integrate beginning and end points when comparing durations were discussed. (Author/CI)

Guidelines for selecting and using pictures to guide instructional decisions and behaviors are based on three areas of research: role of pictures and how they improve learning, how context or environment in which pictures operate can influence usefulness, and how physical and perceptual characteristics of pictures affect their function. (MBR)

The potential instructional uses of three kinds of French signs are outlined, focusing on the signs' function as pointers. The signs include road signs that give directions, public interdiction and instruction signs, and advertising used in public places. Illustrations and sample exercises are included. (MSE)

Surveyed college student (N=34) and general public (N=48) smokers regarding frequency, onset age, and daily situations associated with their habit. Results indicated no differences in either sample for responses according to sex, and correlations between smoking rate and onset age or years of smoking were not significant. (LLL)

Proposes that a levels-of-processing analysis of encoding implies that (a) other things being equal, (e.g., task requirements), deeper information should be equally derivable from pictures and words; but (b) when picture-word differences do occur, they are encoding phenomena which result because task requirements generally favor more discriminable…

Two experiments examined the effect of concurrently holding 0, 2, 4, or 6 nouns in memory on the recognition of visual stimuli briefly presented to the left or right visual fields. (Editor)
