A crucial aspect of everyday behavior is our ability to maintain goal-oriented behavior and to switch between controlled and automated processing rather effortlessly. Besides short-term, reactive adjustments to information processing, it is assumed that cognitive control implements also proactive mechanisms to configure the cognitive system in such a way that context-appropriate and efficient performance is achieved. We examine whether proactive control operates on amodal representations (i.e., stimulus-, response-, and task-unspecific). First, in sensorimotor conflict tasks, we investigate cross-modal and cross-task proactive control effects. If amodal representations underlie proactive adjustments, this should lead to domain-general transfer effects, and we plan to dissociate these proactive effects from those triggered by reactive control mechanisms (which appear to depend on more modal representations). A mathematical model will be used to further specify the mechanisms underlying these adjustments as well. Second, we aim to generalize our approach by investigating proactive control adjustments during language processing.

日常行为的一个关键方面是我们保持目标导向行为的能力，以及在受控和自动处理之间毫不费力地切换的能力。除了短期的，反应性的调整信息处理，它被认为是认知控制也实施积极主动的机制来配置认知系统的方式，上下文适当的和有效的性能是实现的。我们研究了主动控制是否对非模态表征起作用（即，刺激-、响应-和任务-非特异性）。首先，在感觉运动冲突任务中，我们研究了跨通道和跨任务的前摄控制效应。如果非模态表征是主动调整的基础，这应该会导致域一般转移效应，我们计划将这些主动效应与反应性控制机制（似乎依赖于更多的模态表征）触发的主动效应分离开来。还将使用一个数学模型来进一步说明这些调整的机制。其次，我们的目标是通过调查语言处理过程中的主动控制调整来推广我们的方法。
