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…

Discusses C. Milbrath's thesis that artistically talented and less talented children follow different developmental paths because they rely on different ways of responding to the world. Relates this thesis to studies of the childhood work of Paul Klee, Henri Toulouse Lautrec, and Pablo Picasso. (SLD)

Examines preschoolers' understanding of non-observable causal mechanism in causes of illness. Three studies were conducted using subjects from university child care centers. Subjects average five years of age. Results indicated that preschoolers recognize that appearances may be deceiving when it comes to judging causes of illness. Discusses…

Four experiments utilizing the familiarization-novelty preference procedure examined whether 3- and 4-month-olds could form categorical representations for cats versus dogs from the perceptual information available in silhouettes. Findings indicated that general shape or external contour information centered about the head was sufficient for…

Current work has yielded differential findings regarding infants' ability to perceptually detect the causal structure of a means-end support sequence. Resolving this debate has important implications for perception-action dissociations in this domain of object knowledge. In Study 1, 12-month-old infants' ability to perceive the causal structure of…

This study examined the effectiveness of Sensory Stories on "circle time" behaviors in preschool children with autism. This single-system ABA design with a convenience sample of four participants consisted of one week for each A phase and two weeks for the B phase. The intervention phase (B) consisted of reading a Sensory Story from one…
