项目摘要

As an extension of prior findings illustrating the modulation of the conflict monitoring intensity by means of required effort and aversive reinforcement we aim at investigating conflict monitoring and passive avoidance learning in the context of recent theories on anterior cingulate cortex (ACC) activity. For several years, both researchers have successfully collaborated as a dual-career couple as they officially do since 2012 at the University of Bonn. Till date, the neural processes of conflict monitoring and passive avoidance learning as one form of reinforcement learning have been investigated rather independently. However, as long as it has not yet been investigated whether, as postulated by Botvinick, an intensified conflict monitoring results in an intensified passive avoidance learning during task performance, we cannot conclude that an intensified conflict monitoring serves as an aversive teaching signal in decision-making processes and during passive avoidance learning. Those findings would, however, further the most recent and extensive theoretical debate on the functional relevance of the ACC. One possibility to enhance the conflict monitoring intensity and subsequent passive avoidance learning is the quasi-experimental manipulation of motivational factors. In this respect, in Study 1 we aim at varying an individuals motivation by using a maximal vs. average cognitive effort trial-by-trial treatment during performance of a discrimination task. We expect that an increased conflict monitoring intensity induced by means of an individuals effort motivation should intensify passive avoidance learning. If an intensified conflict monitoring and subsequently an intensified passive avoidance learning are of importance for every-day contexts the effect of intensified conflict monitoring on avoidance learning should generalize to discrimination tasks that are embedded into every-day contexts. In Study 2, participants perform discrimination tasks that are based on a vignette describing a more natural context. The possibility to induce conflict monitoring and passive avoidance learning by means of a discrimination task based on faces and a discrimination task based on a vignette has been shown in preliminary studies. Moreover, the presence of peers is manipulated in order to modulate conflict monitoring and thereby passive avoidance learning. To test our hypotheses, well-known event-related potentials are assessed by means of a multi-channel electroencephalogram along with behavioral parameters in large samples (more than 120 participants per study). To investigate the direct relations of individual differences in conflict monitoring and passive avoidance learning growth-modeling is applied as an innovative statistical analysis tool.

作为先前研究结果的延伸，说明了通过所需的努力和厌恶强化来调节冲突监测强度，我们的目的是在最近关于前扣带皮层（ACC）活动的理论背景下研究冲突监测和被动回避学习。几年来，两位研究人员作为双职业夫妇成功合作，因为他们自2012年以来在波恩大学正式合作。到目前为止，作为强化学习的一种形式，冲突监控和被动回避学习的神经过程已经被相当独立地研究。然而，只要它还没有被调查，是否如Botvinick所假设的那样，一个强化的冲突监控的结果，在任务执行过程中的强化被动回避学习，我们不能得出结论，一个强化的冲突监控作为一个令人厌恶的教学信号，在决策过程中和被动回避学习。然而，这些研究结果将进一步最近和广泛的理论辩论ACC.One的功能相关性，以提高冲突的监测强度和随后的被动回避学习是准实验操纵的动机因素。在这方面，在研究1中，我们的目的是通过使用最大与平均认知努力试验的试验，在执行歧视任务的过程中，不同的个人动机。我们预期，通过个人努力动机引起的冲突监控强度增加应该会加强被动回避学习。如果强化冲突监测和随后的强化被动回避学习对日常情境具有重要意义，那么强化冲突监测对回避学习的影响应该推广到嵌入到日常情境中的辨别任务。在研究2中，参与者执行基于描述更自然背景的小插曲的辨别任务。初步研究表明，通过基于面孔的歧视任务和基于小插曲的歧视任务来诱导冲突监测和被动回避学习的可能性。此外，同伴的存在被操纵，以调节冲突监控，从而调节被动回避学习。为了验证我们的假设，众所周知的事件相关电位进行评估的方式与行为参数的多通道脑电图沿着在大样本（超过120名参与者的研究）。为了研究个体差异在冲突监控和被动回避中的直接关系，学习增长模型被应用作为一种创新的统计分析工具。
