Processing Streams in Early Vision

注意力选择我们意识到的东西。当我们的注意力分散时， 我们可能会错过看到的东西，即使我们盯着它，无论它是一个 接近的汽车，斜坡的边缘，或孩子在街上玩耍。注意力扮演着 在组织我们的心理过程和注意力障碍中起着关键作用， 伴随着重大的精神疾病。在本提案中，我们重点关注以下三个方面： 视觉注意力的早期阶段。首先，我们使用注意力追踪任务来检查 索引受关注空间位置的选择地图的属性。 第二，我们研究了从单一的信息摄取的空间特性， 选择位置，使用空间拥挤任务。最后，使用一种新技术， 移动目标，我们分离非视网膜定位后选择分析。注意力是最后的 经验的仲裁者和我们学习周围事件的指南 我们我们对注意力了解得越多，我们就越有能力提高注意力。 心理功能，改善学习策略，建构最佳的 信息，处理注意力缺失，并更好地康复那些 注意力的神经损伤。

Attention selects what reaches our awareness. When our attention wanders, we can miss seeing something even when we are staring right at it, whether it is an approaching car, an edge of a ramp, or child playing in the street. Attention plays a critical role in organizing our mental processes and disorders of attention frequently accompany the major mental diseases. In this proposal we focus on three aspects of the early stages of visual attention. First, we use attentional tracking tasks to examine the properties of the selection map that indexes the attended spatial locations. Second, we study the spatial properties of the uptake of information from a single selection location, using spatial crowding tasks. Finally using a new technique with moving targets we isolate non-retinotopic postselection analyses. Attention is the final arbiter of what ^experience and the guide to our learning about the events around us. The more we learn about attention, the better we will be equipped to enhance mental function, improve learning strategies, construct optimal displays of information, deal with failures of attention, and better rehabilitate those with neurological impairments of attention.
