Activities involving photographs stimulate visual perceptual awareness. Children understand visual stimuli before having verbal capacity to deal with the world. Vision becomes the primary means for learning, understanding, and adjusting to the environment. Photography can provide an effective avenue to visual literacy. (Author)

Results failed to replicate previous findings of a temporal processing deficit specific to the auditory modality in LI children. Further analyses resolved this apparent conflict between the present and earlier studies by demonstrating that age is an important variable underlying modality specificity of perceptual performance in LI children.…

Argues that the development of object perception in infancy involves the detection of structural invariants and that such detection is best understood in the context of dynamic events. (Author/MP)

The classifying behavior of five-year-old children and adults was examined in two studies of restricted classification using triads of stimuli composed of the dimensions of length and density. Results were consistent with the notion of separable perception for adults and integral perception for children. (Author/SS)

Discusses a study comparing children's perception of temporal acoustic cues to that of adults. Subjects were asked to identify voiced or voiced CVC words with uniformly voiceless final obstruents but in which vowel duration was systematically varied. Results show that subject age and vowel duration of test stimuli affect identification processes.…

Twenty-four children (8 to 9 years old) who reversed letters were randomly assigned to either the control or experimental group (15 additional minutes of laterality training per day for 4 weeks). Analysis of results demonstrated that training did not significantly affect the number of reversals. (Author/CL)

Five-month-old infants were habituated to three types of visually presented rigid motion, with duration of fixation as the dependent measure. After reaching a criterion of habituation, a fourth rigid motion (not habituated) and a deformation were presented. (Author/SS)

In order to study infants' sensitivity to binocular information for depth, 11 infants, 20 to 26 weeks of age, were presented with real and stereoscopically projected virtual objects at three distances, and the infants' reaching behavior was videotaped. (Author/SB)

The reactions of 112 10-month-old male infants to the property of curvature were examined using a habituation paradigm with lever pressing as an instrumental response. (SB)

Two experiments tested infants' sensitivity to properties of point-light displays of a walker and a runner that were equivalent regarding the phasing of limb movements. Found that 3-, but not 5-month-olds, discriminated these displays. When the symmetrical phase-patterning of the runner display was perturbed by advancing two of its limbs by 25…

Describes the perception-action approach and the dynamic systems approach to motor development. Discusses the importance of understanding the development of the brain and the importance of longitudinal studies of motor development. (RJC)

Five experiments involving children of 4-11 years investigated partonomic knowledge and its relation to the use of taxonomic organization. Results suggest that children are sensitive to parts of common objects and appear to be able to use this sensitivity to group objects in abstract, function-based, superordinate categories. (RJC)

Investigates the knowledge of thematic and taxonomic relations of 15 children of 26 months and 24 children of 34 months. Both age groups were able to identify thematic matches. However, 34-month-olds were able to recognize a wider range of thematic associations than 26-month-olds. (RJC)

Tested 7 and 10 month olds for perception of correlations among facial features. After habituation to faces displaying a pattern of correlation, 10 month olds generalized to a novel face that preserved the pattern of correlation but showed increased attention to a novel face that violated the pattern. (BC)

Two experiments investigated lateral asymmetries in eight-month-olds' perception of contour-altered and contour-preserved melody changes. Found that infants who heard a contour-altered change showed a left-ear advantage, whereas infants who heard a contour-preserved change showed a right-ear advantage. The pattern of lateralization for melody…
