“…As expected considering previous literature (e.g., Cochet & Vauclair, 2010b;Liszkowski & Tomasello, 2011), in our sample the declarative function was linked to Table 5, pointing gestures appeared to be associated with SVIs of Medium duration. By contrast, reaching gestures were produced with Extra-large vocalizations more often than would be expected by chance.…”

The aim of this study is to explore gestural accompaniment's influence on the acoustic properties of vocalizations in the transition to first words. Eleven Spanish children aged 0;9 to 1;3 were observed longitudinally in a semi-structured play situation with an adult. Vocalizations were analyzed using several acoustic parameters based on those described by Oller et al. (2010). Results indicate that declarative vocalizations have less protosyllables than imperative ones, but only when they are produced with a gesture. Protosyllables duration and f(0) are more similar to those of mature speech when produced with pointing and declarative function than when produced with reaching gestures and imperative purposes. The proportion of canonical syllables produced increases with age, but only when combined with a gesture.

“…Moreover, declarative communicative gestures have been reported to be more tightly interconnected with the vocal system than are imperative gestures (e.g., Camaioni et al, 2004;Franco & Butterworth, 1996). For example, declarative gestures are more frequently accompanied by vocalizations than are imperative gestures (Cochet & Vauclair, 2010b). These different relations with speech between imperative and declarative gestures may be reflected in distinct hand preference patterns, as explained in the following section.…”

a b s t r a c tThis study investigated the development of hand preference for bimanual manipulative activities and pointing gestures in toddlers observed longitudinally over a 5-month period, in relation to language acquisition. The lexical spurt was found to be accompanied by an increase in the right-sided bias for pointing but not for manipulation. Moreover, results revealed a significant correlation between hand preference for imperative pointing gestures and manipulative activities in children who did not experience the lexical spurt during the observational period. By contrast, measures of handedness for declarative pointing were never correlated with those of handedness for manipulation. This study illustrates the complex relationship between handedness and language development and emphasizes the need to take the different functions of pointing gestures into account.Ó 2011 Elsevier Inc.

IntroductionA small body of research has described the development of hand preference in relation to language development, although this topic represents a significant source of information for assessing developmental changes of these two main functional asymmetries. Because the use of one hand for a specific activity mostly reflects the predominant involvement of the contralateral hemisphere, this measure provides an innovative means for investigating its relations with the cerebral control of speech during development. Moreover, different measurements of handedness may allow us to determine whether manipulative activities and communicative gestures are linked to speech at varying degrees. In the Contents lists available at ScienceDirectJournal of Experimental Child Psychology jo urnal homepage: www.elsevier.co m/locate/jecp current study, language level and hand preference for both bimanual manipulation and pointing gestures were measured longitudinally in toddlers between 13 and 21 months of age in an attempt to unravel the complex relationships between language acquisition and the development of handedness. We focused on a key period of language development, namely the lexical spurt, whose onset was expected to be more closely linked to hand preference for pointing than to handedness for noncommunicative actions in the course of development. Moreover, speech-gesture relationships were expected to vary depending on the function served by pointing gestures.

“…communicative and non-communicative) have not been previously shown to be correlated in young children [e.g. 17,49,[52][53][54]. In fact, a disparate range of experimental paradigms for assessing handedness in children has resulted in a variety of patterns of asymmetries depending hand action function [e.g.…”

h i g h l i g h t s• We report on a detailed set of hand actions from two populations of right-handed boys.• Typically developing boys demonstrated a right hand bias for actions to objects.• Typically developing boys also demonstrated a left hand bias for actions to the self.• Boys with autism revealed mixed-handedness for actions to objects and to the self.• Handedness reveals a dissociation for functional specialization of the hemispheres. a r t i c l e i n f o b s t r a c tWe employed a multiple case studies approach to investigate lateralization of hand actions in typically and atypically developing children between 4 and 5 years of age. We report on a detailed set of over 1200 hand actions made by four typically developing boys and four boys with autism. Participants were assessed for unimanual hand actions to both objects and the self (self-directed behaviors). Individual and group analyses suggest that typically developing children have a right hand dominance for hand actions to objects and a left hand dominance for hand actions for self-directed behaviors, revealing a possible dissociation for functional specialization of the left and right hemispheres respectively. Children with autism demonstrated mixed-handedness for both target conditions, consistent with the hypothesis that there is reduced cerebral specialization in these children. The findings are consistent with the view that observed lateralized motor action can serve as an indirect behavioral marker for evidence of cerebral lateralization.
