Evaluated in three experiments a dynamic systems theory account of perseverative errors on "A-not-B" task. Found that 9-month-olds perseverated when reaching for identical targets, but made nonperseverative responses when reaching in the presence of a highly distinctive B target. Reach direction was jointly determined by target's…

Examined three possible explanations for findings that infants detect textural discrepancies based on individual features more readily than on feature conjunctions. Found that none of the proposed factors could explain 5.5-month-olds' superior processing of featural over conjunction-based textural discrepancies. Findings suggest that in infancy,…

Four experiments examined very young infants' expectations about containment events. Found that 2- to 3.5-month-olds recognized that objects could be lowered inside a container with an open but not a closed top. Three-and-a-half-month-olds realized that objects could not pass through the container's back wall and should have moved with it to a new…

Three habituation experiments examined the necessary conditions under which infants invoked the principle of rational action, interpreting behavior as goal-directed action. Found that the rational action principle operated at 9 months but not at 6 months. Perceptual cues indicating agency were not necessary prerequisites for a goal-directed…

Suggests that the findings of Legerstee, Barna, and DiAdamo (2000) are most parsimoniously explained by associative learning and may not constitute a precursor to later understanding of intentionality. Argues for the importance of differentiating between associative and inferential processes and reviews evidence that the understanding of…

Infants start to interpret completed human actions as goal-directed in the second half of the first year of life. In a series of three studies, the understanding of a goal-directed but uncompleted action was investigated in 6- and 9-month-old infants using a preferential looking paradigm. Infants saw the video of an actor's reaching movement…

This research examines whether there are continuities between infant social attention and later theory of mind. Forty-five children were studied as infants and then again as 4-year-olds. Measures of infant social attention (decrement of attention during habituation to displays of intentional action) significantly predicted later theory of mind…

New research in brain development reveals the vital importance of the relationship between caregiver and child in the critical first years of life. This videotape explores the role of parents in stimulating early childhood development. The approximately 29-minute videotape discusses: (1) attachment and the role of touch in creating a bond between…

Over the course of the past decade, the state of Louisiana has developed several documents to articulate expectations for children's learning and development and provide guidance for early childhood educators. The experiences and skills that children develop during the early years are critically important to their success later in school. What…

Forty infants, 10 at 4, 6, 8, and 10 months, were confronted by an experimenter who acted out angry, happy, sad, and neutral facial experssions, accompanied with appropriate vocalizations. The infants' responses were recorded on video tape and rated for attention, negative and positive affect, and activity. Results indicate that the 4-month old…

Theories of imitation learning are examined regarding their account of how the infant acquires the ability to emit a response which resembles a response previously exhibited by another. The role of cognition in imitation learning theory is discussed. (BRT)

Age differences in play were examined cross-sectionally in children at 7, 9, 15, and 10 months of age. (BRT)

Some of the findings of a longitudinal study of three infants between their 11th and 22nd months to document development of linguistic expression of the agent concept indicated that first vocalizations were inconsistently associated with nonverbal agentive behaviors and later mature utterances coded agent-action-recipient events.

Infants were classified as high or low in differential vocal responsiveness (DVR), and tested for degree of response to stimulation by a stranger and to stimulation by their mothers. The infants' DVR classification was related to scores on the Stanford-Binet and the Illinois Test of Psycholinguistic Abilities. (Author/SS)
