A Puzzle about Pointing
Lecturer: Stephen A. Butterfill
Pointing in infancy is nonlinguistic, purposively communicative and referential. We know this because 18- and 14-month-old infants point to request things, inform others about things, and to initiate joint engagement (Liszkowski, 2007). But what model of communication characterises infants’ production and comprehension of pointing gestures? This question is a puzzle insofar as the standard (Gricean) answer is both problematic and apparently well-supported by evidence.

Why Pointing?
‘Pointing may […] represent a key transition, both phylogenetically and ontogenetically, from nonlinguistic to linguistic forms of human communication.’ (Tomasello, Carpenter, & Liszkowski, 2007, p. \ 720)
Pointing in Infancy: The Basics
Because infants’ pointing is sensitive to another’s ignorance (Liszkowski, Carpenter, & Tomasello, 2008) and false belief (Knudsen & Liszkowski, 2012) from around 18 months of age or earlier, we may suppose that pointing in infancy is purposively communicative. That is, in pointing it is part of the infant’s purpose to communicate.
Pointing actions by twelve-month-olds are referential. Rather than merely drawing attention to themselves, infants are performing a communicative action which involves both an addressee and an event or object (Liszkowski, Carpenter, Henning, Striano, & Tomasello, 2004).
Infants also use context in interpreting pointing actions. For instance, 18-month-olds (but not 14-month-olds) interpret the same pointing action differently when it occurs in the context of a game and than it occurs in the context of tidying up (Liebal, Behne, Carpenter, & Tomasello, 2009, p. Experiment 1).
What Model of Communication Characterises Pointing in Infancy?
Moll & Tomasello (2007) as well as Csibra (2010) independently suggest that the model of communication which characterises infants’ production and comprehension of pointing gestures must incorporate communicative intention.1 But what is a communicative intention?
Grice’s view, put very roughly, is that a communicative intention is an intention to provide someone with evidence of an intention with the further intention of thereby fulfilling that intention (Grice, 1989, p. chapter 14). And a communicative action is one performed with a communicative intention.
To illustrate, apply imagine someone pointing to one of two boxes to indicate that you should open this box. On a Gricean account she intends:
that you open the left box;
that you recognize that she intends (1), that you open the left box; and
that your recognition that she intends (1) will be among your reasons for opening the left box.
An Inconsistent Tetrad
- 11- or 12-month-old infants produce and comprehend declarative pointing gestures.
- Producing or comprehending pointing gestures involves understanding communicative actions.
- A communicative action is an action done with an intention to provide someone with evidence of an intention with the further intention of thereby fulfilling that intention.
- Pointing facilitates the developmental emergence of sophisticated cognitive abilities including mindreading

(Moll & Tomasello, 2007, p. 6): ‘to understand pointing, the subject needs to understand more than the individual goal-directed behaviour. She needs to understand that by pointing towards a location, the other attempts to communicate to her where a desired object is located.’ See also (Tomasello et al., 2007, p. 706): ‘infant pointing is best understood—on many levels and in many ways—as depending on uniquely human skills and motivations for cooperation and shared intentionality, which enable such things as joint intentions and joint attention in truly collaborative interactions with others (Bratman, 1992; Searle, 1995).’ ↩
