Instrumentation: Free-Viewing Eyetracker for Studies of Visuo-Spatial Cognition and Psycholinguistics

该拨款为研究人员获得认知/行为研究的重要仪器提供了资金。申请的资金将用于购买一个自由观看的移动眼动监测系统，以及一台计算机工作站和一个显示器，用于显示一些刺激（在其他情况下，刺激将是真实的三维物体和场景）。移动眼动仪允许观看者在进行正常，自然的头部和身体运动的同时检查真实世界的场景或场景的视觉显示。事实上，该系统使研究人员能够获得一个人在自然环境中移动或操纵物体时所注视的精确信息。该仪器将用于认知科学和行为科学的各种研究。这些包括：(1)研究理解者如何快速获得口语句子的解释。没有其他现有的方法允许研究人员测量听觉呈现的句子的瞬间处理。(2)研究现实世界的场景是如何被表示的，以及在有意义的行为的背景下，对象和场景的表示是如何随着时间的推移而动态生成的。(3)研究人类如何能够在新的和熟悉的环境中导航，特别关注眼球运动模式（例如，什么物体被用作路标和地标）。(4)研究人机交互，包括通过“虚拟现实”环境的对象表示和导航。自由观看眼动仪将补充首席研究员现有的实验室设施，并极大地提高了培养本科生和研究生研究智能系统复杂行为的复杂方法的能力。

Ferreira0083570The grant provides funds to allow the investigators to obtain significant instrumentation for cognitive / behavioral research. The requested-funds wo6/ld be used to purchase a free-viewing, mobile eye movement monitoring system, along with a computer workstation and a monitor for displaying some stimuli (in other cases, stimuli will be real, three-dimensional objects and scenes). The mobile eyetracker allows the viewer to examine real-world scenes or visual displays of scenes while making normal, natural head and body movements. Indeed, the system allows researchers to obtain precise information about where a person is looking as he or she moves through or manipulates objects in a natural environment. The instrumentation would be used for a variety of studies in cognitive and behavioral sciences. These include: (1) Research to examine how comprehenders quickly obtain interpretations for spoken sentences. No other existing methodology allows researchers to measure moment-by-moment processing for aurally presented sentences. (2) Research to study how real-world scenes are represented, and how representations of objects and scenes are generated dynamically over time in the context of meaningful actions. (3) Investigations of how humans are able to navigate novel and familiar environments, focusing particularly on eye movement patterns (e.g., what objects are used as guideposts and landmarks). (4) Studies of human-computer interaction, including the representation of objects and navigation through "virtual reality" environments. The free-viewing eyetracker would complement the Principal Investigators' existing laboratory facilities and greatly enhance the ability to train undergraduate and graduate students in sophisticated methodologies for studying complex behavior in intelligent systems.
