人类行为控制理论研究的是认知控制如何根据任务需求进行动态调整。前扣带回（anterior cingulate，ACC）功能的冲突监控理论认为，ACC监控正在进行的加工流中的反应冲突，从而触发认知控制的动员。或者，ACC功能的结果评价帐户表明，ACC监测负面的性能结果，作为一个令人厌恶的学习信号，为未来的行动选择的信息。Botvinick（2007）最近提出，这两种理论可能会收敛于一般厌恶信号的检测。在这里，作者提供了第一个证据，表明冲突被记录为厌恶信号。在情感启动范式中，以一致和不一致的Stroop颜色词为启动词，以正、负刺激为靶词。负目标后评价快于一致的Stroop启动后，和正目标后评价慢于一致的启动后。冲突实际上被记录为厌恶信号，这一发现弥合了前扣带回功能的竞争理论之间的差距，并具有广泛的理论和行为影响，因为它使冲突监控理论适用于更广泛的情况和任务。(C)2011 Elsevier Inc.

Theories of human action control deal with the question of how cognitive control is dynamically adjusted to task demands. The conflict monitoring theory of anterior cingulate (ACC) function suggests that the ACC monitors for response conflicts in the ongoing processing stream thereby triggering the mobilization of cognitive control. Alternatively, the outcome evaluation account of ACC function suggests that the ACC monitors for negative performance outcomes, an information that serves as an aversive learning signal for future action selection. Botvinick (2007) recently suggested that both theories might converge on the detection of aversive signals in general. Here, the authors provide first evidence that conflicts are registered as aversive signals. Congruent and incongruent Stroop color-words served as primes, and positive and negative stimuli as targets in an affective priming paradigm. Negative targets were evaluated faster after incongruent than after congruent Stroop primes, and positive targets were evaluated slower after incongruent than after congruent primes. The finding that conflicts are actually registered as aversive signals bridges the gap between competing theories of ACC function and has broad theoretical and behavioral implications as it makes the conflict monitoring theory applicable to a much wider range of situations and tasks.
