Twenty-four adults (aged 19-35) and 27 adolescents (aged 13-14) played as 'Trustee' in an iterated Trust Game against a pre-programmed set of 'Investor' moves, said to belong to an unknown co-player. Trustee behaviour was examined first in response to normative Investor cooperation, and then in response to a period of social rupture caused by reduced investments. Adolescents were motivated by inequity aversion during normative Investor cooperation, whereas adults over-compensated the Investor. Participants were also identified as coaxers or non-coaxers based on how they responded to social rupture: 'coaxers' were individuals who made at least one relatively generous return to the Investor during this phase. A single coaxing move predicted consistently higher returns to Investors across both normative and reduced investments. Adults showed greater polarisation between coaxing and non-coaxing strategies than did adolescents. These data suggest that adults and adolescents may respond differently to periods of possible social rupture.
二十四名成年人（年龄 19-35 岁）和二十七个青少年（年龄 13-14 岁）在迭代信任游戏中扮演“受托人”的角色，与一套预先设定的“投资者”动作相对抗，据称这些动作属于未知的共同玩家。首先检查了受托人的行为，以响应规范的投资者合作，然后响应由投资减少引起的社会破裂期。青少年在规范的投资者合作中受到不公平厌恶的驱使，而成年人则过度补偿了投资者。参与者还根据他们对社会破裂的反应被确定为哄骗者或非哄骗者：“哄骗者”是指在这个阶段至少对投资者做出了一次相对慷慨的回报的个人。在规范投资和减少投资的情况下，单次哄骗行为都预示着投资者的回报更高。成年人比青少年在哄骗和非哄骗策略之间表现出更大的两极分化。这些数据表明，成年人和青少年对可能的社会破裂期的反应可能不同。
