Abstract Early changes in infants’ ability to perceive native and nonnative speech sound contrasts are typically attributed to their developing knowledge of phonetic categories. We critically examine this hypothesis and argue that there is little direct evidence of category knowledge in infancy. We then propose an alternative account in which infants’ perception changes because they are learning a perceptual space that is appropriate to represent speech, without yet caring up that space into phonetic categories. If correct this new account has substantial implications for understanding early language development.

Phonetic Categories

Infants learn the forms of words by listening to the speech they hear. Though little is known about the degree to which these forms are meaningful for young infants, the words still play a role in early language development. Words guide the infant to his or her first syntactic intuitions, aid in the development of the lexicon, and, it is proposed, may help infants learn phonetic categories.

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.

Do So

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.
