Theory of mind skills and a range of social behaviour in everyday life were assessed in a sample of 21 children with pervasive developmental disorders and 22 normally-developing preschoolers. Parents, teachers and therapists were interviewed using the Vineland Adaptive Behaviour Scales and a new supplementary scale, the "Echelle d'Adaptation Sociale pour(More)
While content words (e.g., 'dog') tend to carry meaning, function words (e.g., 'the') mainly serve syntactic purposes. Here, we ask whether 17-month old infants can use one language-universal cue to identify function word candidates: their high frequency of occurrence. In Experiment 1, infants listened to a series of short, naturally recorded sentences in a(More)
OBJECTIVE To describe the psychological development of children with pervasive developmental disorders over a period of 3 years and to identify the factors linked to their developmental paths. METHOD The study was a collaborative and prospective follow-up study of 219 preschoolers. Retrospective data and enrollment data were collected at the beginning of(More)
Language acquisition involves both acquiring a set of words (i.e. the lexicon) and learning the rules that combine them to form sentences (i.e. syntax). Here, we show that consonants are mainly involved in word processing, whereas vowels are favored for extracting and generalizing structural relations. We demonstrate that such a division of labor between(More)
Recent research has shown that specific areas of the human brain are activated by speech from the time of birth. However, it is currently unknown whether newborns' brains also encode and remember the sounds of words when processing speech. The present study investigates the type of information that newborns retain when they hear words and the brain(More)
An important topic in the evolution of language is the kinds of grammars that can be computed by humans and other animals. Fitch and Hauser (F&H; 2004) approached this question by assessing the ability of different species to learn 2 grammars, (AB)(n) and A(n) B(n) . A(n) B(n) was taken to indicate a phrase structure grammar, eliciting a center-embedded(More)
Sensorimotor representations in the brain encode the sensory and motor aspects of one's own bodily activity. It is highly debated whether sensorimotor representations are the core basis for the representation of action-related knowledge and, in particular, action words, such as verbs. In this review, we will address this question by bringing to bear(More)
Despite the fact that no invariant acoustic property corresponds to a single stop consonant coupled with different vowels (e.g., [da], [de], and [du]), adults effortlessly identify the same consonant embedded in different syllables. In so doing, they solve the invariance problem. Can 3- and 6-month-olds solve it as well? To answer this question, we(More)
The ratio of cytosol concentrations of estrogen receptors to progesterone receptors (ER/PR) can help at the diagnosis of the excessive production of estrogens or (on the contrary) of the lowered function of ER or of the too small expression of the PR gene. We divided the statistical set into the groups with the approximately same concentrations of PR for(More)
