Examined correlates of parents' knowledge about their children's daily experiences. Found between- and within-family differences as a function of mothers' work involvement, sibling composition, and children's and adults' personal qualities. Fathers knew more when mothers worked longer hours. Parents knew more about younger than older offspring.…

Investigated whether individual and developmental differences in look duration were correlated with latency to disengage fixation from a visual stimulus for 3- and 4-month olds. Found that look duration was correlated with disengagement latency. Three-month olds showed slower latencies than 4-month olds. Long-looking infants showed greater…

Examined the relation of positive affect to attention and learning in 5-, 7-, and 9-month olds. Found that at all ages positive affect was associated with long look durations and slower learning. Neutral affect was associated with short looks and faster learning. Learning was faster than expected for infants displaying both short looks and neutral…

Child-directed speech segments produced by mothers of 2- to 6-month olds varying in self-reported depressive symptoms were assessed on a summation test with 4-month olds of nondepressed mothers. Significant positive summation was obtained in infants tested with speech produced by mothers with comparatively fewer self-reported depressive symptoms…

Two studies probed 3- to 6-year olds' beliefs about wishing and its efficacy. Study 1 showed that children had considerable knowledge about wishing and an age-related decrease in beliefs about its efficacy. Study 2 suggested that children reconcile beliefs in wishing efficacy with knowledge about mental/physical relations by situating them more…

Proposes that conceptual change is constrained by the child's conceptual structures and the structures inherent in problem-solving tasks. Uses a microgenetic case study and group data to examine how interaction between strategies children bring to a task and the detailed task structure redirect children's attention and create the possibility of…

Three studies examined the capacity of 4-year olds, kindergartners, second- and fifth graders, and adults to use trait labels (nice, mean, shy, not shy) as tools for making inferences about mental states. Findings suggested that even for 4-year olds, trait labels can serve as a basis for making non-obvious inferences. (Author/KB)

Compared the proportions of nouns and verbs in early vocabularies of English- and Mandarin-speaking toddlers and their mothers. Found that Mandarin-speaking children had relatively fewer nouns and more verbs than English-speaking children. When reading books, children's vocabularies were dominated by nouns but not when playing with toys. Mothers…

Investigated in preschoolers whether the bilingual advantage in cognitive control or selective attention could be found in a nonverbal task, the dimensional change card sort, requiring minimal demands for analysis or representation. Found that bilingual children were more advanced than monolinguals in solving problems requiring high levels of…

Tested hypotheses from an organizational-developmental model for childhood resilience among 7- to 9-year olds. Found that caregiving factors and early development differentiated children with resilient and stress-affected adaptations. Variables reflecting emotionally responsive, competent parenting were direct, proximal predictors of resilience…

Used contextual and transactional approach to examine age and gender differences in experience and consequences of life stress in clinic-referred 8- to 18-year olds. Found that adolescent girls experienced highest interpersonal stress, self-generated within parent-child and peer relationships. Preadolescent girls experienced highest independent…

Examined adjustment problems from late childhood to early adulthood among 500 Swedish girls. Found a diversified pattern of multisyndrome formation in late childhood. The syndrome structure in early adolescence identified externalizing adjustment problems and peer problems. An externalizing syndrome was stable between late childhood and early…

Examined relations between temperament, ability estimation, and injury proneness from toddlerhood through school age. Found that children scoring high on Extroversion and low on Inhibitory Control as toddlers and preschoolers tended to overestimate their physical abilities and have more unintentional injuries at age 6. Children low on Extroversion…

Evaluated an intervention designed to influence mothers' sensitive responsiveness toward their infant by presenting information about the newborn's competence to interact and promoting affectionate handling and interaction. Found that the enhancement group showed greater frequency of co-occurrences involving vocal exchanges, looking to the…

Assessed mothers' childrearing attitudes and toddler behavior to predict mothers' emotions, attributions, parenting goals, and socialization strategies in response to vignettes depicting aggressive and withdrawn child behaviors two years later. Found that most child effects were moderated by maternal attitudes or gender effects. Authoritarian…
