Five experiments used a categorization habituation-of-looking paradigm to investigate infants' categorization of animals and vehicles based on static versus dynamic attributes of stimuli (color images versus dynamic point-light displays). Findings showed that 6-month-olds categorize animals and vehicles based on static and dynamic information, and…

Three studies examined development of the perception of temporally unidirectional transformation, such as dropping blocks, with 3.5- to 6.5-year-olds who compared forward and backward videotapes of events or made individual judgments of what would happen if action were attempted. Findings indicated that even 3.5- to 4.5-year-olds recognized the…

Studied the early development of exploratory behavior in 99 infants of 2-5 months. Results show that there are significant changes in spontaneous multimodal exploration of a novel object between 2 and 5 months. (RJC)

Compares fourth-graders' subtest scores on the Stanford Achievement Test (SAT), the Iowa Test of Basic Skills (ITBS), and the Metropolitan Achievement Test (MAT). Finds right-brain dominant students scored better on four SAT subtests, and left-brain dominant students scored better on four ITBS subtests and two MAT subtests. (NH)

Three experiments examined the exclusivity of perpetually defined categorical representations for animal categories in infants. Results indicated that infants have the capacity for making distinctions among high similar natural kinds but that such find distinctions cannot be made without appropriate exemplars. (SW)

Four- and seven-year olds were asked to make and explain predictions about their abilities to solve perceptual problems, perform the tasks, and explain their success or failure. Results indicated that young children have some clear-cut knowledge, and misconceptions, about their senses. Between four and seven years, children become increasingly…

Reviews a series of studies documenting that key aspects of helpless reactions to failure are present in preschool and early elementary school children. Proposes a preliminary model in which a general conception of self and the notion of this self as an object of contingent worth are sufficient conditions for helplessness. (HTH)

This article critically examines issues of whether children with learning disabilities differentially exhibit concomitant problems in sensory integration (SI) and whether such children are helped by SI therapy. It concludes that research findings indicate that SI therapy is not merely unproven but a demonstrably ineffective remedial treatment for…

The role of context in categorization was examined in four experiments with three month olds. Findings demonstrated that categorization of a novel object is influenced by the context present when the object is initially encountered and by previous encounters with that object in the category context, indicating that infants are capable of…

Spatial cognition entails the ability to mentally represent spatial relations and to anticipate the course and outcome of transformations applied to those relations. The developmental histories of four tasks used to assess the maturity of spatial cognition in children are described. Significant effects were found for age, gender, task, and for…

Examined the visual scanning patterns of infants ages 6, 10, and 13 weeks who viewed static geometric figures. Measures of fixation dwell-times, saccade lengths, and the choices and sequences of saccadic targets revealed that, although younger infants demonstrated salience-guided scanning behavior, older infants increasingly utilized volitional…

Examined the nature of infants' development of social knowledge and the role of caregivers' verbal responses to requests in learning about self and others. Found that, as indicated by changes in request-making behavior, children's conceptualization of the role of self in making requests changes with age; the nature of children's conceptualization…

Briefly reviews current knowledge about the nature of limits of intersubjectivity (ability to acquire and manage representations of self and other through social experience) in autistic children. Describes an observational study of verbal autistic children indicating the presence of intersubjectivity, but with little of the verbal social…

The rapid, disjointed, and vivid style of Sesame Street may impede rather than promote progress toward literacy and the development of voluntary attention. It robs children of the ability to create mental pictures. Contends that it is a failure as an instructional medium. (DM)

Ten children (ages 5-6) and 10 adults participated in discrimination and selective adaptation speech perception tasks using a synthetic consonant-vowel continuum. Results support hypotheses of sensory processing differences in younger, normally developing children compared with adults and show that such abilities appear to be related to speech…
