“意向立场”是将实体视为理性主体的倾向，拥有特定的信念，欲望和意图，以解释和预测其行为。意向性立场是更广泛的社会认知功能的一个组成部分，即心智化。在这里，我们报告了一项研究，调查的神经基板的“在线”心智化，使用PET，要求志愿者猜测对手。为了识别与采取有意立场特别相关的大脑活动，我们使用了一种范式，可以严格控制其他认知需求。志愿者们玩了一个电脑版的儿童游戏“石头，剪刀，布”。“在心理化条件下，志愿者认为他们是在和实验者对抗。在比较条件下，志愿者认为他们正在与计算机进行游戏。事实上，在实际扫描过程中，“对手”在两种情况下都产生了随机序列。唯一的区别是志愿者采取的态度或立场。只有一个地区在志愿者采取有意识的立场时更加积极。这是在前扣带旁皮质（双侧）。这个区域在以前的一些涉及心智化的研究中被激活。然而，这是第一项研究表明，在这个大脑区域的活动和采取有意的立场之间存在特定的联系。(C)2002 Elsevier Science（美国）。
The "intentional stance" is the disposition to treat an entity as a rational agent, possessing particular beliefs, desires, and intentions, in order to interpret and predict it's behavior. The intentional stance is a component of a broader social cognitive function, mentalizing. Here we report a study that investigates the neural substrates of "on-line" mentalizing, using PET, by asking volunteers to second-guess an opponent. In order to identify brain activity specifically associated with adoption of an intentional stance, we used a paradigm that allowed tight control of other cognitive demands. Volunteers played a computerised version of the children's game "stone, paper, scissors." In the mentalizing condition volunteers believed they were playing against the experimenter. In the comparison condition, volunteers believed they were playing against a computer. In fact, during the actual scanning, the "opponent" produced a random sequence in both conditions. The only difference was the attitude, or stance, adopted by the volunteer. Only one region was more active when volunteers adopted the intentional stance. This was in anterior paracingulate cortex (bilaterally). This region has been activated in a number of previous studies involving mentalizing. However, this is the first study suggesting a specific link between activity in this brain region and the adoption of an intentional stance. (C) 2002 Elsevier Science (USA).
