要旨

n the current study, 24- to 27- month- old children (N = 37) used pointing gestures in
a cooperative object choice task with either peer or adult partners. When indicating
the location of a hidden toy, children pointed equally accurately for adult and peer
partners but more often for adult partners. When choosing from one of three hiding
places, children used adults’ pointing to find a hidden toy significantly more often
than they used peers’. In interaction with peers, children’s choice behavior was at
chance level. These results suggest that toddlers ascribe informative value to adults’
but not peers’ pointing gestures, and highlight the role of children’s social expecta-
tions in their communicative development.
