Two groups of children took part in this longitudinal study of eidetic imagery (EI). The New Haven sample consisted of 12 elementary school children, and the Rochester sample consisted of 23 children (aged 7 to 11 years at the beginning of the study). The study was designed to find out some of the qualities of EI and its relationship to memory. An…

Describes two studies in which young children were shown pictures that represented sound with postures and contexts, with conventions, and with combinations of information. Shows that the different types of pictorial representation of sound were not equivalent in their ability to evoke a correct interpretation. (HOD)

Assesses subjects' information output after presentation of pictorial, word, and sentence stimuli. Output is measured in two modes of response: reconstruction and verbal description. Complexity of the stimuli is demonstrated to have important effects on perceptual information processing. (DP)

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…

The present paper is concerned particularly with the processes underlying the perception of the upright, that is, an object in its usual, or familiar, position in space. (Author/RK)

Investigates the effects of predisposed and distinctiveness-based salience on children's classifications in 96 preschoolers and fifth graders given a classification task designed to reflect a developmental shift from integral to separable perception. (Author/MP)

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)

Four experiments tested the hypothesis that the importance of linguistic labels for young children's conceptual organization stems from a privileged processing status of auditory input over visual input. Findings indicated that when auditory and visual stimuli were presented separately, 4-year-olds were likely to process both kinds of stimuli,…

Three experiments investigated 2- to 6-month-olds' perception of the continuity of an object trajectory that was briefly occluded. Results across experiments provided little evidence of veridical responses to trajectory occlusion in the youngest infants, but by 6 months, perception completion was more robust. Results suggest that perceptual…

Infants' visual fixations were monitored while they viewed predictable and unpredictable sequences of stimuli. Analyses of anticipatory fixations indicated that by two months of age, infants form expectations for the reappearance of visual stimuli positioned opposite to each other. By three months, infants rapidly form expectations for asymmetric…

Presented five- and eight-month olds with silent moving and static video images of self, peer, and doll, and sounds of self and nonsocial objects. Found that recognition of one's image develops through experience with dynamic facial stimulation during first eight months. By five months, infants treat their faces and voices as familiar and social…

Examined three- to four-month-old infants' ability to form perceptually based categorical representation in the domains of natural kinds and artifacts. By showing the availability of perceptually driven basic and superordinate-like representations in early infancy that closely correspond to adult conceptual categories, findings underscored the…

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 purpose of this study was to investigate the development of organizational processes for both verbal and spatial stimulus materials within an information processing framework. Children in grades 2 and 4 and adults were tested for their ability to report letter strings reflecting various orders of approximation to English and various dot…

Studies the ability of 5-month-old infants to recall temporal information and use temporal organization by training them to fixate a hierarchically structured or unstructured sequence of stimuli which appeared in four spatial positions. Results are interpreted within a temporal organizational framework; infants appear to use organization within…
