Reviews bases for contemporary discontinuity theories of mental development, presents findings that support alternative proposition of continuity and scrutinizes assessment methods from which these continuity results derive. Also offers several models that help explain the continuity findings, and argues that individual differences in mental…

This study focused on French and U.S. mother-infant dyads interacting in their homes. Infants' visual attention, tactual exploration, vocalization and mothers' mediated and unmediated stimulation and speech to infants were observed. Mothers and infants in the two cultures showed some similarities and some different emphases in their activities,…

Finds that maternal responsiveness in infancy consistently predicts intellectual performance in early childhood. (PCB)

Investigated the role of physiological self-regulation (cardiac vagal tone) in information processing (habituation) in infants. Found that decreases in vagal tone consistently related to habituation efficiency at 2 and 5 months. Within- and between- age suppression of vagal tone predicted accumulated looking time (ALT), but ALT did not predict…

The role of maternal chronological age in prenatal and perinatal history, social support, and parenting practices of new mothers (N=335) was examined. Primiparas of 5-month-old infants ranged in age from 13 to 42 years. Age effects were zero, linear, and nonlinear. Nonlinear age effects were significantly associated up to a certain age with little…

Assessed representational abilities in hearing and deaf 2-year-old children of hearing and deaf mothers. Found group differences in expressive and receptive language based on maternal report and on experimenter assessment, but no differences emerged in child solitary symbolic play or in child- or mother-initiated child collaborative symbolic play.…

Study 1 explored associations between multiple measures of language and symbolic gesture development across ages 3 and 4; Study 2 measured more finely which aspects of language relate to the symbolic representation of actions with objects, and explored associations between symbolic gesture and general intellectual ability. Results showed…

Examined knowledge of mothers with children from 6 to 58 months regarding which item in play and language pairs was more advanced developmentally. Found that mothers' orderings matched those established in developmental literature and were stable over two weeks. Language knowledge was stronger than, and unrelated to, play knowledge. Accuracy was…

Two variants of the habituation paradigm were used to investigate fine orientation discrimination and shape constancy in 34 young infants. Results demonstrate that conditions determine whether young infants show sensitivity to relatively fine variations in pattern orientation or give evidence of shape constancy with the same patterns. (HOD)

Four experiments assessed converging aspects of four-month-old infants' perceptions of visual patterns. Results together corroborate and extend previous findings that vertical symmetry has a special status in early perceptual development and that infants can perceive pattern wholes. (Author/AS)

Reviews research on quantitative and qualitative indexes of play, and relationships between play and language. Finds consistent relationships between duration and level of play throughout early development, and parallel developments in play and language. Indicates that measures of spontaneous activity and habituation in infancy predict…

Using an events-history approach with 40 child-mother dyads, researchers examined prediction from three indexes of children's language, starting at 0;9, and mothers' verbal responsiveness at 0;9 and 1;1, investigating development of language milestones in year 2. Together, children's initial propensities to speak and mothers' responsiveness at the…

A total of 467 mothers of firstborn 20-month-old children from 7 countries (103 Argentine, 61 Belgian, 39 Israeli, 78 Italian, 57 Japanese, 69 Korean, and 60 US American) completed the "Jackson Personality Inventory" (JPI), measures of parenting cognitions (self-perceptions and knowledge), and a social desirability scale. Our first…

Discusses social and didactic dimensions of caregiver behaviors during children's play and changes in caregivers' behaviors as children develop. Compares children's solitary play to play with a caregiver. Addresses the relationship of individual differences in caregiver behaviors to child play, and the effects of parental behavior on children's…

Research on French and European American mothers' childrearing practices, and potential effects of these differences on children's behavioral development, is scarce. This study compared 33 French and 39 European American 20-month-old children and their mothers on exploratory, symbolic, and social play and interaction. French children engaged in…
