A total of 36 American and African mothers and their children in three age cohorts from 6 to 36 months of age interacted around age-appropriate teaching tasks. Major behavioral differences between cultural groups and tasks were demonstrated. (Author/RH)

That a mother's affective illness may interfere with her ability to relate to her child in ways that promote a secure attachment is documented in these data. Depression decreased the likelihood of secure attachment between mother and child. Children of unipolar and bipolar depressed mothers had different patterns of attachment. (RH)

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…

Compared language development of 16 firstborn and 16 secondborn children at 21 months to investigate whether secondborn children benefit from overheard conversations between caregivers and older siblings. Found that secondborn children were more advanced that firstborn in pronoun production, while not differing general language development,…

This study compared language skills in a group of very low-income toddlers with those of a middle-income sample matched on age and sex. The assessment instrument used was the MacArthur Communicative Development Inventory for toddlers, a parent report form. Scores for low-income group were strikingly lower on three key indices evaluated: size of…

Examined distractibility during visual fixations in 6- to 24-month-olds. Found that latency to turn toward a distractor was a function of length of look before distractor onset. Immediately before onset, children had greater sustained lowered heart rate for trials on which they continued looking at television monitor than for trials on which they…

This study compared reciprocal utterances of six hearing mother-hearing toddler dyads and six hearing mother-deaf toddler dyads. Child participants were matched by language stage based on Brown's stages of morphological development and were aged between 25 and 45 months. Child participants were observed interacting with their mothers during…

Why are young children's utterances short? This elicited imitation study used a new task--double imitation--to investigate the factors that contribute to children's failure to lexicalize sentence subjects. Two-year-olds heard a triad of sentences singly and attempted to imitate each; they then again heard the same triad singly and again attempted…

The Early Social Interaction (ESI) Project (Woods & Wetherby, 2003) was designed to apply the recommendations of the National Research Council (2001) to toddlers with autism spectrum disorders (ASD) by using a parent-implemented intervention that (a) embeds naturalistic teaching strategies in everyday routines and (b) is compatible with the…

The purpose of this study was to identify patterns of process characteristics capturing the essence of children's experiences in their natural environment and their possible association with health and well-being operationalized as engagement for young children with and without developmental delay. Data were gathered from 1035 children between 1…

Observations were conducted in Israel on 47 toddlers in sponsored family day care, 18 toddlers in community-based center day care, and 20 toddlers in kibbutz children's homes in an effort to identify differences in the three types of care. Particular attention was given to characteristics of users and caregivers, experiences generated by the…

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…

Three studies examined adults' generic noun phrases in English and Mandarin Chinese from child-directed speech of caregivers interacting with their toddlers. Found that generic noun phrases were reliably identified in both languages. Generic noun phrases most frequently referred to animals. Non-generic noun phrases were used most frequently for…

Examined longitudinal associations between infant-parent attachment and parent/toddler behavior during storybook interaction. Found that infants with insecure-resistant attachment with mothers were less enthusiastic and focused during storybook interaction at 24 months. Mothers of insecure-resistant infants were less warm/supportive, and less…

Background: Though the Down syndrome behavioural phenotype has been described as involving relative strengths in visuo-spatial processing and sociability, and relative weaknesses in verbal skills and motor planning, the early emergence of this phenotypic pattern of strengths and weaknesses has not yet been fully explored. Method: In this study, we…
