This study examined how the outcomes of joint decision making relate to cardiovascular reactions when group members disagree about the decision to be taken. A conflict was experimentally induced during a joint decision-making task, while cardiovascular markers of challenge/threat motivational states were assessed following the biopsychosocial model of challenge and threat (BPSM; J. Blascovich, 2008). Results show that individuals were less likely to adjust their initially preferred decision alternative the more they exhibited a cardiovascular pattern indicative of threat (i.e., relatively high total peripheral resistance and low cardiac output) compared to challenge. This finding extends the BPSM by showing a link between threat and rigidity, and emphasizes the importance of psychophysiological processes for studying intragroup conflict and decision making.
本研究考察了当小组成员对要做出的决策存在分歧时，联合决策的结果与心血管反应之间的关系。在联合决策任务中，通过实验诱发冲突，同时根据挑战与威胁的生物心理社会模型（BPSM；J. Blascovich，2008）评估挑战/威胁动机状态的心血管标志物。结果表明，与挑战相比，个体表现出更多的威胁性心血管模式（即相对较高的总外周阻力和较低的心输出量）时，他们调整最初偏好的决策替代方案的可能性就越小。这一发现通过显示威胁与僵化之间的联系扩展了 BPSM，并强调了心理生理过程在研究群体内部冲突和决策制定中的重要性。
