This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Implicit motor learning is characterized by a lack of awareness for the learning process and its content (Stadler and Frensch 1997) and can be studied using the Serial Reaction Time Task (SRTT) [Nissen and Bullemer, 1987; Keele et al., 1995; Grafton et al., 1998; Willingham et al., 1997, Seidler et al., 2002a]. In this task subjects respond to one of four illuminated boxes by pressing a corresponding key using the four fingers of the right hand. If, unbeknownst to the subject, the visual stimuli are presented as a complex sequence, subjects learn the associated sequence of finger movements, often without being aware of the sequence. There has been much debate in the literature as to the substrates of awareness of learning in this particular task. One of the difficulties has been to assess whether or not the subjects are aware of the sequence and how strong that awareness actually is. The focus of the current project is to examine the substrate of explicit awareness in subjects having been trained in the SRTT.

该子项目是利用该技术的众多研究子项目之一 资源由 NIH/NCRR 资助的中心拨款提供。子项目和 研究者 (PI) 可能已从 NIH 的另一个来源获得主要资金， 因此可以在其他 CRISP 条目中表示。列出的机构是 对于中心来说，它不一定是研究者的机构。 内隐运动学习的特点是缺乏对学习过程及其内容的认识（Stadler 和 Frensch 1997），可以使用串行反应时间任务（SRTT）进行研究 [Nissen 和 Bullemer，1987；基尔等人，1995；格拉夫顿等人，1998； Willingham 等人，1997，Seidler 等人，2002a]。 在此任务中，受试者通过使用右手的四个手指按下相应的键来对四个发光盒子之一做出反应。 如果在受试者不知情的情况下，视觉刺激呈现为复杂的序列，受试者通常会在不知道该序列的情况下学习手指运动的相关序列。 关于这一特定任务中学习意识的基础，文献中存在很多争论。 困难之一是评估受试者是否意识到该序列以及这种意识实际上有多强。 当前项目的重点是检查接受过 SRTT 培训的受试者的外显意识的基础。
