Young children communicate via gesture before they communicate through speech; research has documented strong associations between early gesture use and later language development (e.g., Iverson et al., 2008;Rowe & Goldin-Meadow, 2009a). The goal of this chapter is to summarize the literature on relations between early gesture production and comprehension and language development in typically developing children with a focus on describing the nature of these relations and considering the mechanisms involved. In the first half of this chapter, we review relations between gesture and language skills at different points across early development. In the second half, we offer some potential non-mutually exclusive reasons, and corresponding evidence, for why early gesture might predict later language skills. We see gesture, in addition to being an important means of communication, as a useful indicator of concurrent social-cognitive abilities, a key predictor of later skills, and a potential area for early-intervention research.In this chapter, we define gestures as nonverbal communicative actions that are symbolic, or representational, in nature (Iverson & Goldin-Meadow, 2005), and we use the term language to refer to children's oral language skills, including their vocabulary knowledge and ability to produce multiword utterances (spoken or signed). Early in development, most gestures tend to be deictic, such as pointing and showing, and conventional (e.g., waving, nodding or shaking the head [Bates et al., 1975], giving a thumbs-up [Bates et al., 1975]). Later in toddlerhood, however, children also produce representational or iconic gestures (e.g., holding arms out wide to indicate "big"; Acredolo & Goodwyn, 1988;Özçalışkan et al., 2014). Actions that are noncommunicative are not considered gestures. For instance, many actions performed on objects (e.g., grabbing a block, turning pages) are not gestures, because they do not request a response from the interlocutor and hence are not communicative. However, holding up an object for the interlocutor to see is a deictic gesture because it serves the same deictic function (i.e., showing) as many pointing gestures. Because pointing is the most common gesture used by young children, our review highlights the role of pointing in language development while also examining other early gestures.
