Eye contact is a highly salient and fundamentally social signal. This entails that the mere perception of direct gaze may trigger differentiated neurobehavioral responses as compared to other gaze directions. We investigated this issue using a visual word-spelling task where faces under different gaze directions and head orientations were displayed(More)
Sex differences in human social behaviors and abilities have long been a question of public and scientific interest. Females are usually assumed to be more socially oriented and skillful than males. However, despite an extensive literature, the very existence of sex differences remains a matter of discussion while some studies found no sex differences(More)
Developmental dynamics of SES-related differences in children's production of obligatory and variable phonological alternations. Abstract Numerous studies conducted in both the psycholinguistic and sociolinguistic fields have established that the parents' socioeconomic status (SES) influences several aspects of children's language production. Moreover, a(More)
Child sex and family socioeconomic status (SES) have been repeatedly identified as a source of inter-individual variation in language development; yet their interactions have rarely been explored. While sex differences are the focus of a renewed interest concerning emerging language skills, data remain scarce and are not consistent across preschool years.(More)
The question of the flexibility of nonhuman primate vocal communication remains open today, especially due to early evidence of innately guided vocal production. However, socially determined flexibility can be found when the debate is moved from vocal structure to vocal usage. While increasing evidence shows that the audience quality influences the vocal(More)
Whether social uses of language, in concert with their acquisition, are driven by the awareness of the social value assigned to linguistic variants remains unanswered. The present study examines how 185 French native speakers, aged from 2 to 6 years from different social backgrounds, produce and evaluate a well-known French phonological alternation, the
Although developmental sociolinguistics is a relatively under-researched field, several studies have described children's use of sociolinguistic variables and some have suggested theoretical accounts for the learning mechanisms underpinning their acquisition. Taking a historical point of view, this paper aims firstly to provide an exhaustive review of the(More)
The author studied preschoolers' social networks by investigating the allocation of children's social investment within and across time in a classroom of a French nursery school during an academic year. Observations of children's social exchanges during free play revealed that social behaviors were directed toward particular group members. After an(More)
