Across languages, lexical items specific to infant‐directed speech (i.e., ‘baby‐talk words’) are characterized by a preponderance of onomatopoeia (or highly iconic words), diminutives, and reduplication. These lexical characteristics may help infants discover the referential nature of words, identify word referents, and segment fluent speech into words. If so, the amount of lexical input containing these properties should predict infants’ rate of vocabulary growth. To test this prediction, we tracked the vocabulary size in 47 English‐learning infants from 9 to 21 months (...) and examined whether the patterns of growth can be related to measures of iconicity, diminutives, and reduplication in the lexical input at 9 months. Our analyses showed that both diminutives and reduplication in the input were associated with vocabulary growth, although measures of iconicity were not. These results are consistent with the hypothesis that phonological properties typical of lexical input in infant‐directed speech play a role in early vocabulary growth. (shrink)

Ample evidence from various quarters indicates that the perceptual-cognitive competence of the pre- and perinatal human being is significantly greater than was once thought. Some of the evidence of this emerging picture of early competence is reviewed, and its importance both as evidence of the biogenetic structural concept of “neurognosis” and for a theory of enculturation is discussed. The literature of pre- and perinatal psychology, especially that of developmental neuropsychology, psychobiology, and social psychophysiology, is incorporated, and some of the implications (...) of these data for a theory of enculturation are suggested.

Interaction between adults and infants by nature constitutes a strong powerasymmetry relationship. Based on the assumption that communicative practices with infants are inseparably intertwined with broader cultural ideologies of good child care, this paper will contrast how parents in two distinct socio-cultural communities deal with power asymmetry in interactions with 3-months old infants. The study consists of a microanalysis of videotaped free play mother-infant interactions from 20 middle class families in Muenster, Germany and 20 traditional farming Nso families in Kikaikelaki, (...) Cameroon. Analysis followed a discursive psychology approach. The focus of analysis is on how mothers handle and negotiate power-distance in these interactions and what discursive strategies they draw on. Mothers in both groups used various forms of directives and control strategies. The Muenster mothers, however, mainly used mitigated directives that can be seen as strategies to reduce the competence gap between mother and child, while the Nso mothers mainly used upgraded directives to stress the hierarchical discrepancy between mother and child. The different strategies are discussed in light of the prevailing broader cultural ideologies and the normative orientations that they reflect. Finally, the findings are discussed with regard to possible developmental consequences of these distinct cultural practices for the child. Keywords: power-asymmetry; mother-infant interaction; discursive psychology; culture; Nso farmers; Muenster middle class families. (shrink)

This article offers an alternative approach to paradigms that cast culture solely as a nurturing influence on children's language development. It proposes a dimensional model of Child-Directed Communication to delineate ways in which a community's habitus may impede the communicative potential of children with neuro-developmental conditions such as severe autism. It argues that certain features of Euro-American CDC are illadapted for autistic children. Due to inertia, caregivers often find themselves unable to transcend the limitations of CDC habitus. Yet, occasionally, a (...) transformation in CDC emerges that more effectively engages children with impairments. The article analyzes one such transformation forged in the niche of a unique mother–son relationship in India and then introduced in the USA. (shrink)
