A proposed model of communicative behavior suggests a series of seven progressively more complex levels of communicative competence: (1) behavior state; (2) recognitory; (3) contingency; (4) instrumental; (5) triadic; (6) verbal-contextual; and (7) verbal-decontextual. Tables define these levels in detail and list their characteristics. Each level…

This study was designed to assess genetic influence on behavioral inhibition and its varying expression in 92 monozygotic and 86 dizygotic twin pairs. Infant behavior and mother-child interaction were observed and videotaped during structured play sessions at age 14, 20, 24, and 36 months. Analysis of the results suggests that most of the overlap…

A total of 36 normally developing children of 13-30 months of age were evenly divided into three age groups and observed while playing with their mothers. Their communicative behaviors were recorded according to intent and level. Intent was classified as comment, request, and reject; levels were nonverbal, verbal-contextual, and…

Age, specific emotion, and linguistic modality (verbal vs. non-verbal) were predicted to affect knowledge of emotion in young preschoolers (N = 45, mean age = 40.7 mos). Prosocial response to emotion and knowledge of emotion were also predicted to be related, given naturalistic observation and the use of contextually valid emotion knowledge…

On the basis of two sets of videotaped observations collected on same-sex, same-age and mixed-age dyads composed of children 18 and/or 24 months old, issues concerning research on infants and toddlers are addressed. The first set of observations was a simple description of the structure and content of children's peer interaction during 15 minutes…

Two studies investigated whether young children acquiring verbs at an exceptional rate can use the syntactic structure of familiar and unfamiliar verbs to make conjectures about some aspect of the meanings of those verbs. The preferential looking paradigm (Golinkoff and Hirsh-Pasek, 1981) was used to set up a naturalistic pairing of scene and…

A study was conducted to examine continuities and discontinuities in the socialization experiences of toddler-age children attending day care. Interaction between adults and children during socialization episodes was observed in home and day care settings. Parents rated their extent of agreement with the teacher regarding discipline and the extent…

Examines the role of the partner in the development of social pretend play in two related studies. In both studies, toddler age children played with same-age and five-year-old partners. In both studies, two-year-olds engaged in more social pretend play with older than same-age partners. (Author/BB)

This study examined the prevalence of otitis media with effusion (OME) in 14 children (ages 8-66 months) with developmental disabilities attending center-based childcare. Although younger children had more OME than older children, children with Down syndrome had the highest incidence of OME regardless of age. Implications of OME for fluctuating…

Discusses a study of conversational dyadic interaction between children aged 1.5 to 3 years; their 4-, 5-, 7-, or 8-year-old siblings; and their mothers. Mothers were more supportive conversational partners and adapted their level of speech more than siblings. (GH)

Discusses the importance of modeling, hints, and other information contexts for providing a link to establishing new problem-solving strategies for toddlers and older children. Discusses the use of the microgenetic approach for yielding valuable information about strategic development despite the lack of availability of verbal reports. Suggests…

Examined in six experiments toddlers' use of syntactic cues to learn proper names and count nouns. Found that by 24 months, both girls and boys were significantly more likely to select a labeled object if they had heard a proper name than if they had heard a count noun. At 20 months, neither girls nor boys demonstrated this effect. (Author/KB)

A recent graphic schemas account of drawing development that emphasizes the appropriation of graphic conventions has provided an alternative to constructivist theories, which have viewed development as a progression through universal stages. The present study addresses the limitations of this account by investigating younger children than have…

This study explored infants' ability to infer communicative intent as expressed in non-linguistic gestures. Sixty children aged 14, 18 and 24 months participated. In the context of a hiding game, an adult indicated for the child the location of a hidden toy by giving a communicative cue: either pointing or ostensive gazing toward the container…

By the age of 1 year toddlers demonstrate distinct coping habits for dealing with frustration. However, these habits may be open to change and reorganization at subsequent developmental junctures. We investigated change in coping habits at 18-20 months, a normative age for major advances in social cognition, focusing on the dynamic systems…
