Results of discriminating and monitoring tasks indicate that performance deteriorates over time when a specific object must be distinguished from previously presented nonspecific objects in a display which changes quickly. The results offer a basis for distinguishing between perceptual and response processes underlying the vigilance decrement.…

Article suggests certain tasks must be performed before a pupil can learn to read. What these tasks are depends upon whether teaching method is analytic--introducing words as whole units to be broken down--or synthetic--introducing individual written signs as sounds, to be built up into meaningful units.

A nonpsychotic experimental psychologist presents a self-report of several highly organized visual, auditory, and kinesthetic hallucinations that occurred during a 3-day period prior to spinal disc surgery. Probable factors related to the production of the phenomena are described and the relation between hallucination and diagnosis is briefly…

Examines the influence of cultural factors and cultural norms on self-imagery and their implications for art education. (Author/RK)

A comparison was made of the Rorschach responses and the Human Figure Drawings of a group of 21 adult Down's syndrome Ss and the responses of a group of 21 other adult mentally retarded persons (non-Down's syndrome group). (Author)

Investigates the interaction between a model's head turn and an observer's perception of being looked at, as a function of the model's visible eye. (Author/RK)

Results of a study of children's ability to perceive grouped vs. ungrouped objects representing the numbers 1 through 9 showed that perceiving elementally grouped objects was significantly easier than nonelementally grouped objects, and elementally grouped objects in a pattern were significantly easier than non-patterned groupings.

Thirteen infants were presented with a moving object under two lighting conditions to investigate the role of vision in early reaching. Infants were tested twice, at 5 and 7.5 months of age. The results suggest that proprioceptive feedback and sight of the target allowed for successful reaching with limited visual information, even in relatively…

Two experiments examined the impact of slow development of processing differences among faces in the spacing among facial features (second-order relations). Computerized tasks involving various face-processing skills were used. Results of experiment with 6-, 8-, and 10-year-olds and with adults indicated that slow development of sensitivity to…

Four experiments investigated newborns' ability to discriminate, recognize, and learn visual information embedded in the schematic face-like patterns preferred at birth. Results indicated that newborns discriminated face-like stimuli relying on their internal features and recognized a perceptual invariance between face-like configurations in…

An 18-item "Shortened Visuospatial Questionnaire" (SVS) was validated twice, first by verifying that children (ages 8-13) identified with the SVS questionnaire as having visuospatial learning disability (VSLD) (n=54) actually showed visuospatial deficits on psychometric evaluation, and second, by rating with the SVS a clinically identified…

A study investigated the accuracy and speed of face recognition in 26 children (ages 7-10) with Pervasive Developmental Disorder Not Otherwise Specified. Subjects needed an amount of time to recognize the faces that almost equaled the time they needed to recognize abstract patterns that were difficult to distinguish. (Contains references.)…

Visual-spatial orienting in 10 high-functioning adults with autism was examined. Compared to controls, subjects responded faster to central than to lateral stimuli, and showed a left visual field advantage for stimulus detection only when laterally presented. Abnormalities in attention shifting and coordination of attentional and motor systems are…
