Home Language Environment

The home language environment is critical to early language development and subsequent skills. However, few studies have quantitatively measured the home language environment in low-income, developing settings. This study explores variations in the home language environment and child language skills among households in poor rural villages in northwestern China. Audio recordings were collected for 38 children aged 20–28 months and analyzed using Language Environment Analysis (LENA) software; language skills were measured using the MacArthur–Bates Mandarin Communicative Developmental Inventories expressive vocabulary scale. The results revealed large variability in both child language skills and home language environment measures (adult words, conversational turns, and child vocalizations) with 5- to 6-fold differences between the highest and lowest scores. Despite variation, however, the average number of adult words and conversational turns were lower than found among urban Chinese children. Correlation analyses did not identify significant correlations between demographic characteristics and the home language environment. However, the results do indicate significant correlations between the home language environment and child language skills, with conversational turns showing the strongest correlation. The results point to a need for further research on language engagement and ways to increase parent–child interactions to improve early language development among young children in rural China.

Abstract We investigated the development of early-latency and long-latency brain responses to native and non-native speech to shed light on the neurophysiological underpinnings of perceptual narrowing and early language development. Specifically, we postulated a two-level process to explain the decrease in sensitivity to non-native phonemes towards the end of infancy. Neurons at the earlier stages of the ascending auditory pathway mature rapidly during infancy facilitating the encoding of both native and non-native sounds. This growth enables neurons at the later stages of the auditory pathway to assign phonological status to speech according to the infant’s native language environment. To test this hypothesis, we collected early- latency and long-latency neural responses to native and non-native lexical tones from 85 Cantoneselearning children aged between 23 days and 24 months and 16 days. As expected, a broad range of presumably subcortical early-latency neural encoding measures grew rapidly and substantially during the first two years for both native and non-native tones. By contrast, longlatency cortical electrophysiological changes occurred on a much slower scale and showed sensitivity to nativeness at around six months. Our study provided a comprehensive understanding of early language development by revealing the complementary roles of earlier and later stages of speech processing in the developing brain.

How do children as young as 2 years of age know that numerals, like one,have exact interpretations, while quantifiers and words like a do not?Previous studies have argued that only numerals have exact lexicalmeanings. Children could not use scalar implicature to strengthen numeralmeanings, it is argued, since they fail to do so for quantifiers(Papafragou & Musolino, 2003). Against this view, we present evidence thatchildren’s early interpretation of numerals does rely on scalarimplicature, and argue that differences between numerals and quantifiersare due to differences in the availability of the respective scales ofwhich they are members. Evidence from previous studies establishes that (1)children can make scalar inferences when interpreting numerals, (2)children initially assign weak, non-exact interpretations to numerals whenfirst acquiring their meanings, and (3) children can strengthen quantifierinterpretations when scalar alternatives are made explicitly available.
