Insights
Children
Area of Science:
- Developmental Psychology
- Social Psychology
- Behavioral Economics
Background:
- Collaboration involves risks due to temptations to defect.
- Commitment, both explicit and implicit, can mitigate these risks.
- Implicit commitment arises from mutual awareness of interdependence.
Purpose of the Study:
- To investigate how commitment levels influence children's defection from collaboration.
- To examine age-related differences in responding to explicit and implicit commitments.
- To understand the development of understanding interdependence and obligation.
Main Methods:
- 192 pairs of 3- and 5-year-old children participated in a collaborative game.
- Children were bribed to opt out of collaboration under three commitment conditions: explicit, implicit, and none.
- Behavioral responses to defection temptations were recorded.
Main Results:
- 3-year-olds resisted bribes more under explicit commitment than parallel play.
- 5-year-olds resisted bribes more in both implicit and explicit commitment conditions compared to no commitment.
- 5-year-olds demonstrated a clearer understanding of interdependence-based implicit commitment.
Conclusions:
- Children at both ages exhibit commitment to partners when faced with defection incentives.
- Older children (5-year-olds) better grasp the concept of implicit commitment derived from mutual interdependence.
- Developmental differences exist in the understanding and application of social commitments.
Abstract:
The problem with collaboration is that there are temptations to defect. Explicit joint commitments are designed to mitigate some of the risks, but people also feel committed to others implicitly when they both know together that they each hold the other's fate in their hands. In the current study, pairs of 3-year-old and 5-year-old children (N = 192) played a collaborative game. One child was offered individual rewards (bribed) to opt out of the collaboration. In 3 different conditions, the level of the commitment was manipulated. Three-year-old children were more likely to resist the bribes when there was an explicit joint commitment to the partner than when they were only playing in parallel, with their reactions to an implicit commitment falling in between. Five-year-olds were more likely to resist bribes in both the implicit and explicit commitment conditions than in the no-commitment condition. Thus, children at both ages showed some level of commitment to a collaborative partner in the face of bribes to defect, but only 5-year-olds clearly appreciated that a common-ground understanding of interdependence between partners generates an implicit commitment or obligation.
