DESCRIPTION (provided by applicant): Regulating cognitive operations is one of the self's most important executive functions. Three studies are proposed to explore the role of the self's executive resources in memory management. Self resources will initially be depleted by tasks that require self-regulation, including the Stroop color-word interference task or an emotion regulation task. Subjects will then perform memory tasks that require purposeful memory management, including directed forgetting and prospective memory. The results are expected to show that self-regulatory exertion impairs later memory activity that relies on the self's executive influence. This research will extend knowledge of executive resources and memory in a number of ways. First, these studies will demonstrate memory impairment due to prior resource expenditure. This depletion effect is related to, but distinct from, effects of concurrent cognitive load. Second, these studies will indicate that intentional behavior may be disrupted by the reduced ability to manage memory after depletion. Finally, understanding the role of executive resources in memory may move provide a clearer understanding of the component processes of cognition that are, and are not, affected by the state of the self's resources.

描述（由申请人提供）：调节认知操作是自我最重要的执行功能之一。三个研究提出了探索自我的执行资源在记忆管理中的作用。自我资源最初会被需要自我调节的任务耗尽，包括Stroop颜色词干扰任务或情绪调节任务。然后，受试者将执行需要有目的的记忆管理的记忆任务，包括定向遗忘和前瞻性记忆。研究结果预计将表明，自我调节的努力损害了后来的记忆活动，依赖于自我的行政影响。这项研究将以多种方式扩展执行资源和记忆的知识。首先，这些研究将证明由于先前的资源消耗而导致的记忆障碍。这种消耗效应与并发认知负荷的效应有关，但又不同。其次，这些研究将表明，有意的行为可能会被耗尽后管理记忆的能力降低所破坏。最后，理解执行资源在记忆中的作用可能会更清楚地理解认知的组成过程，这些过程受到自我资源状态的影响。
