Do 12-month-old infants maintain expectations of contingent or non-contingent responding based on prior experiences
with unfamiliar and familiar adults?
The current study examined whether infants use previous encounters for maintaining expectations for adults’
contingent responding. An unfamiliar adult responded contingently or non-contingently to infant signaling during an initial play
situation and 10 min later presented an ambiguous toy while providing positive information (Experiment 1; forty-two
12-month-olds). The infants in the contingent group looked more at the adult during toy presentation and played more with the toy
during the concluding free-play situation than the infants in the non-contingent group. When the parent had responded contingently
or non-contingently to infant bids (Experiment 2; forty 12-month-olds), the infants in the contingent group tended to look more at
the parent and tended to play more with the toy than did the infants in the non-contingent group. The results indicate that from
just a brief exposure, infants form expectations about adults’ responsiveness and maintain these expectations of
contingent/non-contingent responding from one situation to another.
