Examined relationships between social contingency in mother-child interaction and the social competence of 47 two-year-olds from low-income families. Found that social contingency was related to children's use of self-regulatory strategies but not to empathic responsiveness. Child negative emotionality and gender contributed to explanations of…

Examined 2-year-olds' comprehension and production of novel nouns, verbs, or actions at 3 intervals after training conducted in massed or distributed exposures. Found that for comprehension, children learned all item types in all training conditions at all retention intervals. Production was better for nonverbal actions than for either word type…

Studied children's grasp of make-believe transformations they had seen enacted. Children indicated the pretend outcome by choosing a picture depicting no change or a picture depicting the pretend change. Older children chose correctly, even with the addition of a picture of an irrelevant transformation, but younger children did not. Autistic…

Examined discourse styles of mothers and fathers when talking separately with their three year olds about shared events. Found two distinct narrative styles, neither of which was associated with parent gender. Parents of daughters were generally more elaborative than parents of sons, and daughters participated in the conversations to a greater…

Tested predictions of infantile amnesia theory compared with social-interactionist account of autobiographical memory. Found maternal reminiscing style and self-recognition when child was 19 months old uniquely predicted children's shared memory reports across time, even with children's initial language and nonverbal memory factored out.…

Mental state language was examined in Mandarin- speaking and Cantonese-speaking toddlers. Results suggested that theory-of-mind development was similar to that in English, with early use of desire terms followed by other mental state references. Much earlier emergence of desire terms and infrequent use of thinking terms suggests cultural…

This study examined the stability and continuity of early-identified behavior problems and the factors associated with this stability. Children and their mothers (N=125) were seen when the children were 2 and 4 years of age. Maternal reports of child externalizing behavior and laboratory observations of child noncompliance were stable from age 2…

To explore how online speech processing efficiency relates to vocabulary growth in the 2nd year, the authors longitudinally observed 59 English-learning children at 15, 18, 21, and 25 months as they looked at pictures while listening to speech naming one of the pictures. The time course of eye movements in response to speech revealed significant…

Mothers of about 100 toddlers completed the Toddler Temperament Scale when their children were 12, 18, and 24 months old. Other data sets were available for: (a) factors representing laboratory observations; (b) measures of mothers' temperament by mothers and by social workers; and (c) measures of the home and family environment by social workers.…

Assessed a one-month, home-based intervention, designed to optimize parental reading of picture books to young children. Children in the experimental group scored significantly higher than control children on posttests of expressive language ability and had a higher mean length of utterance and a lower frequency of single words. (SKC)

Aimed to establish extent to which toddlers' social behaviors in recurrent play groups may become characterized by an increased consistency and predictability during second year of life, particularly first versus third trimester. Concurrent observations in contrasting settings provided data for examining differences in extent of cross-situational…

Twelve two year olds were taught novel count nouns for related but unfamiliar objects. Children's interpretation of the relations between the nouns was mediated by the similarity of the objects, a result that suggests that, by age two, children have the conceptual and lexical abilities necessary for establishing hierarchical relations. (LB)

Examined cultural variation in management of attention by 14- to 20-month olds and caregivers from Guatemalan Mayan community and middle-class community of U.S. European-descent families. Found that Mayan caregivers and toddlers were more likely to attend simultaneously to spontaneously occurring competing events than were U.S. caregivers and…

A longitudinal study examined the role of a mapping system in 2-year olds' learning of color and size words. Results indicated that the children acquired color maps in a characteristic order and showed a different acquisition pattern for size words. Results suggest that learning word associations may promote color-word acquisition; learning color…

Interviewed 13- to 34-months olds about their trauma injury within days and after 6, 12, and 18 or 24 months. Found that the youngest demonstrated little verbal recall. Some who could not narrate about past events at time of injury could verbally recall target words 18 months later. Most of the oldest children demonstrated good verbal recall 2…
