Perceptual decision-making, the act of quickly drawing inferences from sensory information and making appropriate responses, is a critical foundation of human behavior. The timing and the interaction between sensory and response processes in decision making are the focus of this collaborative research program. Neuroscience data has revealed that response planning may be engaged before perceptual processing finishes suggesting that the interaction of perception and action may be a critical aspect of making decisions. To investigate this, we develop novel experiments that use human electroencephalography (EEG) to measure the time course of perception, attention, and motor processes. We incorporate students from communities that have historically been underserved by higher education STEM programs directly into this research through courses, all-day science events, and a three-week summer school. There is a tight correspondence where curricula in the educational activities enable these students to carry out novel research throughout the project period supported by researchers. Graduate students play a critical role in the development and implementation of these student projects. These educational programs will be made available to other institutions that seek to enhance STEM education through research training in neuroscience.All of the experiments make use of innovations in single-trial EEG methods for measuring the dynamics of perceptual and motor activity while participants make decisions about stimuli placed in varying contexts. Novel experimental methods are used to track and manipulate the time-course of attentional control of the flow of sensory information in the brain. A new area of perceptual neuroscience will be developed with unique tactile perception and decision making experiments. The summer school curriculum focuses on students proposing, programming, running, analyzing, and presenting their own research. The curriculum incorporates programming skills, matrix algebra and signal processing skills, and statistical methods. The goal is for the students to design, control, and analyze human neuroscience experiments. Interactions with graduate students and faculty mentors will enable students to realize their projects and develop their ambitions to pursue science careers.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

感知决策是从感官信息中快速汲取推论并做出适当回应的行为，是人类行为的关键基础。决策过程中感觉和响应过程之间的时间和互动是该协作研究计划的重点。神经科学的数据表明，在感知处理饰面之前可能会参与响应计划，这表明感知和行动的相互作用可能是做出决策的关键方面。为了研究这一点，我们开发了使用人类脑电图（EEG）来测量感知，注意力和运动过程的时间过程的新型实验。我们将来自历史上高等教育STEM计划的社区的学生直接通过课程，全天科学活动和为期三周的暑期学校融合到了这项研究中。在教育活动中的课程使这些学生能够在研究人员支持的整个项目期间进行新的研究。研究生在这些学生项目的发展和实施中发挥着关键作用。这些教育计划将提供给其他试图通过神经科学的研究培训来增强STEM教育的机构。所有实验都利用单审EEG方法中的创新来衡量感知和运动活动的动态，而参与者则在不同环境中做出有关刺激的决策。新型的实验方法用于跟踪和操纵大脑感觉信息流动流的注意力控制时间。具有独特的触觉感知和决策实验将开发一个知觉神经科学的新领域。暑期学校课程的重点是学生提出，编程，跑步，分析和介绍自己的研究。该课程结合了编程技能，矩阵代数和信号处理技能以及统计方法。目的是让学生设计，控制和分析人类神经科学实验。与研究生和教师导师的互动将使学生能够实现自己的项目并发展野心以从事科学职业。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估评估标准来通过评估来支持的。
