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，即从感官信息中快速推断并做出适当反应的行为，是人类行为的重要基础。决策中感觉和反应过程的时机和相互作用是该合作研究项目的重点。神经科学数据表明，反应计划可能会在感知处理完成之前进行，这表明感知和行动的相互作用可能是决策的关键方面。为了研究这一点，我们开发了新的实验，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。我们通过课程、全天科学活动和为期三周的暑期学校，将来自历史上高等教育 STEM 项目服务不足的社区的学生直接纳入这项研究。教育活动中的课程使这些学生能够在研究人员的支持下在整个项目期间开展新颖的研究，这之间存在着紧密的对应关系。研究生在这些学生项目的开发和实施中发挥着关键作用。这些教育项目将提供给其他寻求通过神经科学研究培训来加强 STEM 教育的机构。所有实验都利用单次试验脑电图方法的创新来测量感知和运动活动的动态，同时参与者对不同环境中的刺激做出决定。新的实验方法用于跟踪和操纵大脑中感觉信息流的注意力控制的时间过程。通过独特的触觉感知和决策实验，将开发感知神经科学的新领域。暑期学校课程的重点是学生提出、编程、运行、分析和展示自己的研究。该课程包含编程技能、矩阵代数和信号处理技能以及统计方法。目标是让学生设计、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他们的项目并发展他们追求科学职业的抱负。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
