Successful language learning in bilinguals requires the differentiation of two language systems. The capacity to discriminate rhythmically close languages has been reported in 4-month-olds using auditory-only stimuli. This research offers a novel perspective on early language discrimination using audiovisual material. Monolingual and bilingual…

Between 6 and 9 months, while infant's ability to discriminate faces within their own racial group is maintained, discrimination of faces within other-race groups declines to a point where 9-month-old infants fail to discriminate other-race faces. Such face perception narrowing can be overcome in various ways at 9 or 12 months of age, such as…

Sentiment analysis is a computational method that automatically analyzes the valence of massive quantities of text. Basic sentiment analysis involves extracting and counting emotionally-laden keywords from passages of text (e.g., "hate," "love," "happy," "sad"). This study describes using sentiment analysis…

The ability to infer the emotional states of others is central to our everyday interactions. These inferences can be drawn from several different sources of information occurring simultaneously in the communication situation. Based on previous studies revealing that children pay more heed to situational context than to emotional prosody when…

Previous research has demonstrated that adults are successful at visually tracking rigidly moving items, but experience great difficulties when tracking substance-like "pouring" items. Using a comparative approach, we investigated whether the presence/absence of the grammatical count-mass distinction influences adults and children's…

Infants have remarkable abilities to learn several languages. However, phonological acquisition in bilingual infants appears to vary depending on the phonetic similarities or differences of their two native languages. Many studies suggest that learning contrasts with different realizations in the two languages (e.g., the /p/, /t/, /k/ stops have…

The articles in this special issue provide a complex picture of acquisition in bilinguals in which the factors that contribute to patterns of performance in bilingual children's two languages are myriad and diverse. The processes and contours of development in bilingual children are influenced, not only by the quantity, quality, and contexts…

The present eye-tracking study aimed to investigate the impact of auditory speech information on 12-month-olds' gaze behavior to silently-talking faces. We examined German infants' face-scanning behavior to side-by-side presentation of a bilingual speaker's face silently speaking German utterances on one side and French on the other side, before…

Relations between bilingual children's patterns of conversational code-switching (responding to one language with another), the balance of their dual language input, and their expressive and receptive proficiency in two languages were examined in 115 2½-year-old simultaneous Spanish-English bilinguals in the U.S. Children were more likely to…

Much research on the quality of child care reveals it--in the case of low-quality child care--to be related to poorer child functioning, net of confounding factors, perhaps especially in the case of cognitive-linguistic performance. Recent work using data from the National Institute of Child Health and Human Development (NICHD) Study of Early…
