These results are the first to demonstrate that infants as young as 18 months of age cannot only detect a speaker’s verbal inaccuracy but also use this information to attenuate their word recognition and learning of novel actions. “
“The literature reports some contradictory results on the degree of High Content Screening phonological specificity of infants’ early lexical representations in the Romance language, French, and Germanic languages. It is not clear whether these discrepancies are because of differences in method, in language characteristics, or in participants’ age. In this study, we examined whether 12- and 17-month-old

French-speaking infants are able to distinguish well-pronounced from mispronounced words (one or two features of their initial consonant). To this end, 46 infants participated in a preferential looking experiment in which they were presented with pairs of pictures together with a spoken word well pronounced or mispronounced. The results show that both 12- and 17-month-old infants look longer at the pictures corresponding to well-pronounced words than to mispronounced words, but show no difference between the two mispronunciation types. These

results suggest that, as early as 12 months, French-speaking infants, like those exposed to Germanic languages, already possess detailed phonological representations of familiar words. “
“The aim of this study was to investigate Neratinib cost the relations between pregnancy and childbirth factors and subsequent quality of maternal

interactive behavior in a sample of 116 full-term infants and their mothers. Mothers reported on the conditions of childbirth when infants were 6–8 months of age, and their interactive behavior was observed during a home visit at 12 months. Results showed that mothers who did not report health problems during pregnancy and who had longer pregnancies, shorter hospital stays, natural deliveries, and infants with greater birthweight were found to be more sensitive during interactions with infants at 12 months. All these relations held after accounting for socio-economic factors and maternal psychological distress, except for the effect of type of delivery. This pattern of results, however, was almost Pregnenolone exclusively due to mothers who already had at least one other child. Very few such relations were found among primiparous mothers. “
“The two aims of the study were (a) to determine when infants begin to use force intentionally to defend objects to which they might have a claim and (b) to examine the relationship between toddlers’ instrumental use of force and their tendencies to make possession claims. Infants’ and toddlers’ reactions to peers’ attempts to take their toys were assessed in three independent data sets in which the same observational coding system had been used (N = 200).
