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.

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 内隐运动学习的特征在于缺乏对学习过程及其内容的意识（Stadler和Frensch 1997），并且可以使用序列反应时间任务（SRTT）来研究[Nissen和Bullemer，1987; Keele等人，1995; Grafton等人，1998;威灵厄姆等人，1997年，Seidler等人，2002年a]。 在这个任务中，受试者通过用右手的四个手指按下相应的键来对四个照亮的盒子中的一个做出反应。 如果受试者不知道，视觉刺激被呈现为复杂的序列，受试者学习手指运动的相关序列，通常没有意识到该序列。 在这一特定任务中，关于学习意识的基础，文献中有很多争论。 困难之一是评估受试者是否意识到了这个序列，以及这种意识实际上有多强。 目前项目的重点是研究在SRTT中接受过培训的受试者的明确意识的基础。
