Abstract
Infants often start pointing toward the end of their first year of life. Pointing shows a strong link to language, perhaps because parents label what infants point to. In the present study, we tested whether 9-month-olds' pointing was related to parental sensitivity and concurrent and subsequent vocabulary scores. Observations were made of 88 9-month-old infants in free-play situations with their mothers. Less than half the infants produced at least one index-finger point. The mothers' reactions to their infants' behaviour were coded for sensitivity. The mothers of the infants who pointed were less directing and responded more contingently than the mothers of the infants who did not point. However, there was no difference in vocabulary scores of pointers and non-pointers, either concurrently or at 12 and 18 months of age. These results could mean that parents' reactions play an important role in shaping pointing to be communicative.
