Using a visual fixation procedure, the present study tested whether French-learning 14-month-olds have the knowledge of syntactic categories

of determiners and pronouns, respectively, and whether they can use these function words for categorizing novel words to nouns and verbs. The prosodic characteristics of novel words stimuli for noun versus verb uses were balanced. The only distinguishing Maraviroc solubility dmso cue was the preceding determiners versus subject pronouns, the former being the most common for nouns and the latter the most common for verbs, i.e., Det + Noun, Pron + Verb. We expected that noun categorization may be easier than verb categorization because the co-occurrence of determiners with nouns is more consistent than that of subject pronouns with verbs in French. The results showed that infants grouped the individual determiners as one common class, and that

they appeared to use the determiners to categorize novel words into nouns. However, we found no evidence of verb categorization. Unlike determiners, pronouns were not perceived as a common syntactic class. “
“Young children begin helping others with simple instrumental problems from soon after their first birthdays. In previous observations of this phenomenon, both naturalistic and experimental, children’s parents were in the room and could potentially have influenced their behavior. In the two current studies, we gave 24-month-old children the opportunity to help an unfamiliar adult obtain an out-of-reach object when the parent (or a friendly female adult) (i) was present but passive, selleck chemical (ii) was present and highlighted the problem for the child, (iii) was buy Rucaparib present and actively encouraged the child to help, (iv) was present and ordered the child to help, or (v) was absent from the room. The children helped at relatively high levels and equally

under all these treatment conditions. There was also no differential effect of treatment condition on children’s helping in a subsequent test phase in which no parent was present, and children had to disengage from a fun activity to help. Young children’s helping behavior is not potentiated or facilitated by parental behavior in the immediate situation, suggesting that it is spontaneous and intrinsically motivated. “
“Research suggests that nonlinguistic sequence learning abilities are an important contributor to language development (Conway, Bauernschmidt, Huang, & Pisoni, 2010). The current study investigated visual sequence learning (VSL) as a possible predictor of vocabulary development in infants. Fifty-eight 8.5-month-old infants were presented with a three-location spatiotemporal sequence of multicolored geometric shapes. Early language skills were assessed using the MacArthur-Bates CDI.
