It takes two to tango: An interdependence analysis of the spiraling of perceived trustworthiness and cooperation in interpersonal and intergroup relationships

Abstract

We present three spiral reinforcement models that describe how mutual perceptions of trustworthiness and/or mutual cooperation may develop in dyadic interpersonal and intergroup relationships: a perceived trustworthiness spiral model, a cooperation spiral model, and a perceived trustworthiness-cooperation spiral model that posits a relatively more complex spiraling between trustworthiness perceptions and cooperation. Actor-Partner Interdependence Model (Kashy & Kenny, 2000) analyses of data from two joint venture business simulations provided support for the spiral models in interpersonal and intergroup relationships. While all three models received some support, the perceived trustworthiness-cooperation spiral received the most consistent support, suggesting that trust perceptions play a crucial mediating role in the development of cooperation in both interpersonal and intergroup interactions. Overall, it does take two to tango: the development of mutual trust and cooperation involves an intricate dance that spirals over time and is fundamentally affected by partners' initial moves.
