Investigates the experimental treatments (scanning practice and perceptual training-drawing) developed by Salome and Szeto, 1976, in an attempt to determine the training effects upon students' representational drawing performances. (Author/RK)

Presents findings of a study on the visual perceptual dimension of cognitive structure as it relates to achievement in college biology. Results indicate a possibility of using visual recall probes for the early detection of learning differences related to achievement. (SL)

A visual-spatial approach to the study of attention dysfunction was presented. The hypotheses of broadened and narrowed attention were tested by comparing peripheral visual discrimination of acute schizophrenic, chronic schizophrenic, and normal subjects within two regions of the functional visual field.

Efficiency of three discrimination training procedures was compared for 21 mentally handicapped children. Results showed that two programmed techniques (graded stimulus and prompt fading) did not differ significantly, but both were significantly superior to trial-and-error learning. (Author/CL)

Analyzes sex-related differences between mental rotation rate and spatial ability among adults, 14-year-olds, and 9.5-year-olds to determine the extent to which rotation rate is a correlate of various abilities. (HOD)

Reports on three experiments that investigated why young children's perceptions of bimodal speech are less influenced by the visual component of speech than adults' perceptions are. Results argue in favor of the explanation that children are poorer lipreaders than adults. (HOD)

Facial configuration and height were systematically varied as four different strangers--a male and female child, a female adult and a small female adult (midget)--each approached 40 different infants. The infants responded as if there were 3 classes of persons, suggesting that both size and facial configuration cues were used. (Author/SB)

Visual preference technique was found to be a method for exploring the genesis of normal and abnormal selective attention, pattern discrimination, and recognition memory. The study of infants with differing degrees of risk for mental subnormality produced substantial evidence for relationship between early visual selectivities and future…

This paper reviewed briefly the major types of masking effects obtained with various methods and the major theories or models that have been proposed to account for these effects, and outlined a three-mechanism model of visual pattern masking based on psychophysical and neurophysiological properties of the visual system. (Author/RK)

Research indicated that visual discrimination training could compensate for the impulsive response style of first-graders on reading tests. (GW)

Research shows that children of about 10 years can remember photographs of faces upside down almost as well as those shown upright and are easily fooled by simple disguises. This ability to encode orientation-specific configurations of a face may reflect maturational changes in the right cerebral hemisphere. (MLH)

Some infants, soon after birth, are capable of storing visual information as reflected in their ability to detect and respond to change in the immediate environment. (Author)

Testing Pollack's hypothesis that decreases in effective contour contrast (resulting from a decrease in receptor sensitivity with age or from a change in actual stimulus contrast) lead to decreases in illusion magnitude. Conclusions are questioned by Sjostrom and Pollack (PS 501 740). (Author/MB)
