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. In everyday life, directional cues provide a rich source of visual information that can influence human behavior in many ways. Directional cues from people and other animals, such as their eye gaze direction or head orientation, provide an indication of where their attention is directed, and thus can alert us to potentially important objects and events in our environment. Other, nonbiological, directional cues such as arrows can perform a similar function. Recently it was discovered that gaze and arrow cues trigger a shift of attention that is fast and automatic. The research to date has focused on measuring this attentional shift using a single cue and a single target; however, in the real world we are continually exposed to a variety of directional cues, and these cues almost always appear within a rich and complex visual context, and often in situations in which our goals and affective states are influential. The overall objective of this project is to understand how we process, respond to, and make use of directional cues in our daily lives. Specifically, the goals of this project are: to investigate the effects of directional cues in rich visual environments; to identify, using electrophysiological recording techniques, the neural activity associated with shifting attention in response to directional cues; to explore the roles of context, attentional control, and conscious awareness in orienting to directional cues; and to identify the essential properties of visual directional information and investigate how this information can be most effectively conveyed. This research will lead to a refinement of our theories of human spatial attention in general, and of the neural processes that underlie shifts of spatial attention in response to biologically and socially relevant directional information in the visual environment. Alan Kingstone serves as Dr. Friesen's Individual Project Mentor. Dr. Kingstone will visit Dr. Friesen's laboatory once per year (and vice versa), and will assist Dr. Friesen in the design and interpretation of experiments, and with the preparation and critical review of Dr. Friesen's eventual R01 grant proposal submission.

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。 在日常生活中，方向线索提供了丰富的视觉信息来源，可以在许多方面影响人类的行为。来自人类和其他动物的方向性线索，例如他们的眼睛注视方向或头部方向，提供了他们的注意力指向何处的指示，从而可以提醒我们注意环境中潜在的重要物体和事件。其他非生物性的方向性提示，如箭头，也可以起到类似的作用。最近发现，凝视和箭头提示触发了快速和自动的注意力转移。迄今为止的研究都集中在使用单一线索和单一目标来测量这种注意力转移;然而，在真实的世界中，我们不断地暴露在各种方向性线索中，这些线索几乎总是出现在丰富而复杂的视觉环境中，而且经常出现在我们的目标和情感状态具有影响力的情况下。这个项目的总体目标是了解我们如何在日常生活中处理，响应和利用方向性线索。具体来说，本项目的目标是：调查丰富的视觉环境中的方向线索的影响;识别，使用电生理记录技术，与转移注意力的反应方向线索的神经活动;探索的作用，注意力控制，和有意识的意识定向方向线索;并识别视觉方向信息的基本属性，并研究如何最有效地传达该信息。这项研究将导致我们的理论的人类空间注意力的一般，和神经过程的基础转移的空间注意力在视觉环境中的生物和社会相关的方向信息。 艾伦金斯顿担任博士弗里森的个人项目导师。金斯顿博士将每年访问弗里森博士的实验室一次（反之亦然），并将协助弗里森博士设计和解释实验，并与准备和严格审查博士弗里森的最终R01赠款提案提交。
