Examines the effect of different training methods on perceptual learning of impulsive children. A matching to sample method (M), and a differentiation method (D) were used. Data indicated that Ss receiving D training learned to process features distinguishing stimuli; whereas, Ss receiving M training showed no preference for a particular mode of…

Seven-year-olds compared successively presented oblique lines which varied as to their position within a square display and their relation to the diagonal axis of the display. Children apparently encoded lines in terms of position and axis features. They used a categorical spatial representational system to compare oblique lines. (Author/RD)

To investigate the effects of perceptual training upon selected measures of reading achievement in grade 1, 12 experimental classrooms of randomly selected first graders received a 29-day adaptation of the Frostig Program for the Development of Visual Perception. Thirteen control classes added comparable time to the regular reading instructional…

Pioneering research has shown that infants are capable of perceptual discrimination and has provided some indication of the nature of the discrimination; that is, what stimuli are differentiable. Studies have demonstrated that significant effects exist, in stimulus-pair comparisons, for age of infant, speed of movement of stimulus during…

The role of perceptual discrimination in the development of the ability to selectively process information was investigated. Using an incidental learning paradigm, the discriminability between relevant and irrelevant stimuli was experimentally varied in two ways: (1) contiguity versus non-contiguity in spatial arrangements and (2) alternating…

For the age range tested there is a lag between the perception and production of certain facial expressions. (Authors)

Cumulative evidence obtained from this and other studies suggests that perceptual training to attend to shape and object contours will affect representational drawing. (Authors/MB)

Rejects the neuronal fatigue, or selective adaptation, hypothesis of young infant habituation. Holds that studies cited by Dannemiller and Banks do not support the inferences of selective adaptation. Rejects the hypothetical neurophysiological mechanism of neuronal fatigue. Proposes that studies do not indicate that young infants' visual cortical…

Research findings are reviewed concerning infants' abilities to discriminate parents from other social stimuli during the first 6 months of life. The term "discrimination" is used to signify the ability of infants to respond differentially to two or more social stimuli. Studies reviewed are categorized in terms of the visual, auditory,…

In order to enhance the understanding of visual literacy, one of its constituents, visual learning (VL), is examined in terms of underlying assumptions, hypothesized behaviors, and implications of both assumptions and behaviors. Assumptions are: (1) VL encompasses all changes in behavior arising from the individual's responses to visual…

Four studies with infants and preschool-age children examined various pattern perception tasks considered to be related to the perceptual basis of the development of reading skills. Study 1 used 28 neonates to test the hypothesis that supplemental stimulation (rocking, patting, holding) has measurable effects upon attention to visual patterns.…

Examines whether three-month-old infants can detect variations within the single expression category of smiling and whether individual differences in infants' sensitivities are related to identifiable mother or infant behaviors. (HOD)

Children and adults performed a divided attention task and two selective attention tasks with shapes that were either spatially integrated or separated. Results indicate that integrated stimuli are initially perceived as wholes, and separated stimuli as features, at all ages. (BC)
