Responds to Needham and Baillargeon's criticisms and offers an alternative resolution of the conflicting results between the laboratories regarding abilities of infants less than 12 months to use property/featural information for object individuation. Maintains that kind concepts are acquired as infants approach their first birthday and that…

Previous research on infant swimming has reported contradictory findings. Cross-sectional observations revealed a disorganized phase between about 3 and 12 months, which was attributed to "cortical inhibition" and implied slow learning (McGraw, 1939). However, training with a single infant during this period revealed rapid acquisition (McGraw,…

The relationship between infants' performance on a Piagetian scale between the ages of 12 and 24 months and the infants' scores on the Stanford-Binet at the age of 31 months was assessed. (JMB)

Reviews recent empirical findings toward three cognitive developmental perspectives: the fears of infancy, the discontinuous quality of stages in cognitive functioning, and the capacity for resilience in cognitive development. (DEP)

Cognitive functioning at 15 months (as measured by the Uzgiris and Hunt scales) was examined in terms of individual differences in habituation of independent groups at 2, 3, and 4 months of age. (Author/JMB)

Two aspects of the cognitive development of a 14- to 18-month-old blind child are reported: the development of procedures for the intentional control of objects and the development of certain classificatory skills. (Author)

Argues for an interactionist model of the relation between cognition and motivation in early infancy. (Author/SS)

Attempts to identify the point at which prelinguistic vocalizations are used by infants as a means of communication. A significant relationship between Piagetian causal developmental level and the occurrence of intentional vocalizations was found in a study of 46 infants with a mean age of 10.7 months. (JMB)

In this longitudinal study a close association between affective expression and cognitive development was demonstrated. (SB)

Two experiments tested 10-month-old infants' categorization abilities. Infants were presented with a sequence of stimuli depicting members of a given category. Stimuli representing nonmembers of the category were inserted into the sequence. Infants appeared to disregard the nonmembers in the sequence. (MDM)

Three experiments involving 80 infants provide evidence that infants at 2.5 and 4 months represent objects and surfaces that they no longer perceive and that they operate on their representations to derive information about an event they have never perceived. Experiments suggest that cognition develops concurrently with perception and action. (SLD)

Four experiments with the habituation procedure investigated 14-22-month-olds' ability to attend to correlations between static and dynamic features embedded in a category context. In Experiment 1, infants were habituated to four objects that exhibited invariant relations between moving features and motion trajectory. Results revealed that…

Reviews current research on infant and toddler physical development, cognitive development, and language acquisition. Provides a list of suggested activities, safety concerns, and opportunities for caregivers to enhance child development. (SD)

Because of the sparcity of research on infants' response to social events, especially different categories of people, infants between 8 and 18 months of age were introduced to five different social events: strange adult male and female, strange 4-year-old female, mother, and self. The infants' responses indicated that approach affects stimulus…

Distributed by the U.S. Departments of Agriculture, Education, and Health and Human Services, this pamphlet provides parents with information and advice about their infants in the seventh month of life. Following a brief description of developmental characteristics at this age, the pamphlet offers advice on a variety of topics, including: your…
