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

Ferreira 0083570该基金提供资金，使研究人员能够获得认知/行为研究的重要仪器。申请的资金将用于购买一个自由观看的、移动的眼动监测系统，沿着一个计算机工作站和一个用于显示某些刺激的监视器（在其他情况下，刺激将是真实的三维物体和场景）。移动的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，该系统允许研究人员获得关于一个人在自然环境中移动或操纵物体时所看位置的精确信息。该仪器将用于认知和行为科学的各种研究。这些研究包括：（1）研究翻译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每时每刻的处理。(2)研究如何表示真实世界的场景，以及如何在有意义的动作背景下随着时间的推移动态生成对象和场景的表示。(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)人机交互的研究，包括对象的表示和通过“虚拟现实”环境的导航。自由观察眼动仪将补充主要研究人员现有的实验室设施，并大大提高培训本科生和研究生的能力，以研究智能系统中复杂行为的复杂方法。

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.
