Children's memory of single infant experience was evaluated. At 6.5 months, infants participated in study of reaching in light and dark for sounding object. Children repeated dark procedure in laboratory when they were either one year or two years older. Older children with infant experience reached and grasped the sounding object significantly…

Attempted to replicate findings of a previous study which found that mother-toddler interaction during problem solving was related to the child's prior attachment security. Examined the relationship between problem-solving interactions on the one hand, and mother-child interactions at home and infant temperament on the other. (PCB)

Activities of 28 primiparous mothers and their infants that occurred during naturalistic interactions at home were observed when infants were two and five months of age. Findings indicated that infants appeared to be flexible and plastic in their behavioral repertoires, and were influenced by their mothers. Mothers adapted to the behaviors of…

Notes that assertion of autonomy helps predict teenager's attitude toward pregnancy and parenthood and that ability to predict future relationship with infant has direct implications for achievement of adaptive outcome. Contends that interpersonal outcome of parent-infant relationship may be predicted by adolescent's behaviors with infant. The…

Compared mothers' play with infants with Down syndrome (DSC) and typically developing children (TDC) matched for mental or chronological age. Found that TDC mothers exhibited more object demonstrations with their developmentally younger children, who showed less object play. DSC mothers were more directive and supportive than mothers of younger…

Compared parents and nonparents to examine differences in the use of gender stereotyping to classify children's toys, and differences according to children's ages. Findings for 206 toys suggest that while toys are gender stereotyped for all age groups, there is more flexibility in gender stereotyping of toys for infants and toddlers. (SLD)

Two experiments tested whether newborns could discriminate their own and another newborn's cry. Results indicated that awake newborns expressed facial distress more frequently and longer to another newborn's cry than to their own. Sucking decreased significantly between pretest phase and first minute of another infant's cry. Asleep infants'…

This study compared efforts to regain their infants' visual attention of 40 mothers (either deaf or hearing) and 40 9-month-old infants (either deaf or hearing). Findings indicated a greater reliance by deaf mothers on visual strategies to regain infant attention and a greater emphasis on vocalizations by hearing mothers, regardless of infant…

Reviews research indicating linguistic knowledge is not innate, that the infant brain is highly differentiated at birth, that processing biases that lead to the "standard brain plan" are innate and localized but not specific to language, and that the infant brain is highly plastic, permitting alternative "brain plans." (Author/CR)

Examined association between residential density and parent/child speech in toddlers and parents participating in the University of Kansas Language Acquisition Project. Found that parents in crowded homes spoke with children in less complex, sophisticated ways than parents in uncrowded homes. The association was mediated by parental…

Prospective longitudinal study examined continuity in infants' experience to attachment representations at 18 years. Found that adults with dismissing representations had received less sensitive maternal care than adults with secure or preoccupied representations. Adverse life events through age 12, especially parental divorce, reduced likelihood…

Adult and 10- and 12-month olds participated in two experiments to determine reliance of infants on object-kind information in solving problems of object individuation. Findings converge with those of object-first hypothesis of developmental course of object individuation. Findings suggest that young infants may represent one concept as criteria…

Analyzed vocalizations/verbalizations from children acquiring English or French in later single-word period to identify trochaic bias. Found that neither language's vocalizations were exclusively trochaic. French/English differences in iambic productions and acoustic realization of accent were traceable to adult input. Distribution of trochaic and…

Review of the literature on early development of typical and abnormal stereotyped and self-injurious behaviors found that such behaviors usually reach a maximum at age 2 and then decline but may increase again when the child reaches school age. Findings suggest that the second year may be a sensitive period for emergence of abnormal stereotyped…

Investigates the lexical forms of speech sound production of a child learning Norwegian and English bilingually from birth. Data for lexical analysis are words attested by the MacArthur Development Inventory for Infants and diary data when the child was 1;2 to 1;8 years of age. (Author/VWL)
