在日常生活中，人们可以将预期的特定线索（例如，参观餐馆）与期望的动作（例如，健康的饮食）。或者，当一个人遇到同样的提示时，诸如“我打算吃得更健康”的意图会提供行动的选择。在第一种情况下，一个特定的线索触发了一个特定的行动;在第二种情况下，一个人必须以一种更自我发起的方式行动。作者使用功能性磁共振成像对这些情况进行了比较。参与者要么被指示以特定的方式对目标事件做出反应（线索条件），要么被告知他们会为这种反应得分，而没有被告知他们是必要的（自我启动条件）。虽然条件不同，只是在措辞的指示，自我发起的条件与较差的性能和更大的活动，主要是额顶叶网络。在自我发起和线索条件下的目标的反应产生了更大的活动，在外侧和内侧布罗德曼区10，分别。作者认为，这些结果反映了不同类型的教学后，自我发起与外部暗示行为的不同需求，与P. M. Gollwitzer及其同事。
In everyday life, one can link anticipated specific cues (e.g. visiting a restaurant) with desired actions (e.g., ordering a healthy meal). Alternatively, intentions such as "I intend to eat more healthily" present the option to act when one encounters the same cue. In the first case, a specific cue triggers a specific action; in the second, one must act in a more self-initiated manner. The authors compared such scenarios using functional magnetic resonance imaging. Participants were either instructed to respond in a particular manner to target events (cued condition) or told that they would score points for Such responses, without being told that they were necessary (self-initiated condition). Although conditions differed only in the wording of instructions, the self-initiated condition was associated with poorer performance and greater activity in a predominantly frontoparietal network. Responses to targets in the self-initiated and cued conditions yielded greater activity in lateral and medial Brodmann area 10, respectively. The authors suggest that these results reflect differing demands for self-initiated versus externally cued behavior following different types of instruction, in line with the distinction between goal intentions and implementation intentions proposed by P. M. Gollwitzer and colleagues.
