In infancy, use of gesture and the ability to engage in joint attention with others both predict later language development. Conceptually, gesture and joint attention abilities may reflect a similar underlying social‐communicative skill. However, these abilities are often studied separately. Despite the fact that gesture is often used in episodes of joint attention, little is known about the degree to which measures of gesture use and joint attention ability are associated with one another or how they similarly, or differentially, predict children's language abilities. Participants in this study were 53 infants. At 12 months, multiple measures of infants’ gesture use were gleaned from a free–play interaction with a parent. Infants’ responding to and initiating joint attention were measured via the Early Social‐Communicative Scales (Mundy et al., 2003). Infants’ expressive and receptive language was measured at 24 months with the Mullen Scales of Early Learning (Mullen, 1995). A factor analysis including gesture and joint attention measures indicated that at 12 months, joint attention, particularly responding to joint attention, reflects a similar underlying construct with infant gesture use, yet they uniquely predict later language ability.
