This chapter reviews sensitivity to prosodic information at the lexical level during the first year of life, considering crosslinguistic data that bear on both monolingual and bilingual acquisition. First, we discuss infants’ early ability to discriminate lexical stress, and how this sensitivity changes across development depending on the native language, reflecting the acquisition of native prosodic properties. Second, we present data establishing the emergence of language-specific lexical stress preferences during that same period, also attesting language-specific acquisition. We then discuss data on the less well studied perception of lexical pitch accent and tone. Finally, we consider the role of lexical stress in early word segmentation abilities, and discuss the representations and processes underlying early prosodic perception at the lexical level.
