RUI: Establishment of a high-density event-related potential laboratory at an undergraduate college for the study of cognitive neuroscience

这笔赠款支持在波莫纳学院的本科院校建立一个128通道事件相关电位（ERP）实验室，以研究与认知相关的大脑活动的空间和时间维度。这样做，这个项目符合NSF认知神经科学倡议的标准。三个项目将在赠款期间进行。第一个是探索在信息的初始编码过程中大脑活动的空间和时间模式与随后的源记忆判断之间的关系。具体来说，我们将调查编码事件相关电位期间和随后的源记忆判断，包括时间顺序，空间位置，回忆与熟悉的判断之间的关系。第二条研究线将调查在何种程度上稳定的个体差异的心理和生物措施的压力是预测记忆功能和伴随的ERP活动。我们特别感兴趣的是评估是否个人与高慢性压力将有受损的记忆功能，这是否会证明在一个减少旧/新的振幅差异外显的，但不是内隐的记忆conditions.The第三行的研究将暴露一个不同的学生群体使用电生理成像方法，探讨经典的心理学文献的问题。我们正在设计一个学生研究项目，以调查一个代表性不足的学生特别感兴趣的问题。具体来说，我们将使用高密度的ERP记录来研究大脑活动如何与文化的个人主义-集体主义维度相关的信息的认知处理相关联。这项拟议的研究将作为一个模型，说明如何使用高密度ERP记录来探索心理问题。我们预计，将这种技术应用于心理问题所获得的知识将鼓励其他心理学和神经科学教师在未来使用ERP技术。

This grant supports the establishment of a 128-channel event-related potential (ERP) laboratory at an undergraduate institution, Pomona College, in order to investigate the spatial and temporal dimensions of brain activity associated with cognition. In doing so, this project meets the criteria for the NSF Cognitive Neuroscience initiative. Three projects will be conducted during the grant period. The first is an exploration of how spatial and temporal patterns of brain activity during the initial encoding of information are related to subsequent source memory judgments. Specifically, we will investigate the relationship between encoding event-related potentials during and subsequent source memory judgments, including temporal order, spatial location, and recollection versus familiarity judgments.The second line of research will investigate the extent to which stable individual differences in psychological and biological measures of stress are predictive of memory functioning and concomitant ERP activity. We are specifically interested in assessing whether individuals with high chronic stress will have impaired memory functioning and whether this will be evidenced in a decreased old/new amplitude difference for the explicit but not implicit memory conditions.The third line of research will expose a diverse group of students to the use of electrophysiological imaging methods to explore issues from the classic psychological literature. We are designing a student research project to investigate an issue of particular interest to underrepresented students. Specifically, we will use high-density ERP recordings to investigate how brain activity may be associated with cognitive processing of information related to the individualism-collectivism dimension of culture. The proposed research will serve as a model for how psychological issues can be explored using high-density ERP recordings. We anticipate that the knowledge gained from applying this technique to psychological problems will encourage the use of ERP techniques among other psychology and neuroscience faculty in the future.
