合作和竞争是社会认知的两种基本模式，需要对自己和他人的行为进行监控，并采取特定的心理定势。在这个功能性磁共振成像中，研究对象根据一套预定义的规则玩一个特别设计的电脑游戏，要么与另一个人合作，要么与另一个人竞争。将这些条件下的血流动力学反应与独立玩游戏的相同受试者的血流动力学反应进行对比。合作和竞争的立场导致激活一个共同的额顶叶网络subserving执行功能，以及前额叶，参与自主觉醒。此外，不同的区域被发现有选择性地与合作和竞争，特别是眶额皮质在前者和下顶叶和内侧前额叶皮质在后者。这种模式反映了与他人合作或竞争时所涉及的不同心理框架。根据进化心理学和发展心理学的证据，我们认为，合作是一个社会奖励的过程，并与特定的左内侧眶额皮质参与。(C)2004年爱思唯尔公司All rights reserved.
Cooperation and competition are two basic modes of social cognition that necessitate monitoring of both one's own and others' actions, as well as adopting a specific mental set. In this fMRI, study individuals played a specially designed computer game, according to a set of predefined rules, either in cooperation with or in competition against another person. The hemodynamic response during these conditions was contrasted to that of the same subjects playing the game independently. Both cooperation and competition stances resulted in activation of a common frontoparietal network subserving executive functions, as well as the anterior insula, involved in autonomic arousal. Moreover, distinct regions were found to be selectively associated with cooperation and competition, notably the orbitofrontal cortex in the former and the inferior parietal and medial prefrontal cortices in the latter. This pattern reflects the different mental frameworks implicated in being cooperative versus competitive with another person. In accordance with evidence from evolutionary psychology as well as from developmental psychology, we argue that cooperation is a socially rewarding process and is associated with specific left medial orbitofrontal cortex involvement.
