The long-range goal of the proposed research is to increase our understanding of the role of orienting and defensive responses in attention and information processing in humans. Over the past several decades extensive research on human subjects has failed to resolve many of the basic issues related to this question. The purpose of the proposed research is to conduct a systematic analysis of orienting and defensive responses in animal subjects from three different phyla, to analyze the changes in autonomic nervous system activity that accompany those responses, and to study the effects of those responses on attention and information processing i the three classes of animals. Achieving a fuller understanding of the function of orienting and defensive responses in a wide range of animal species may help us to understand the role of those responses in attention and information processing in humans. The first phase of the proposed research will systematically examine the cardiac and behavioral response to neutral, prey, and predator stimuli in selected amphibians (e.g., Bufo marinus), reptiles (e.g., Sceleporus poinsetti), and mammals (Sigmodon hispidus). Although the particular species chosen differ in a number of ways they are all subject to predation by the same predators and consume similar prey species. This will allow us to study the cardiac and behavioral responses of the different animal species to the same prey and predator stimuli, in the form of either real or simulated prey and predators. One major focus of the proposed research will be to record the changes in heart rate that occur during the various stages of predation and predator-escape. The first three stages of those sequences are the same and consist of (1) detection, (2) identification, and (3) assessment. In the predation sequence the assessment stage is followed by the capture response (e.g., approach and/ or attack). In the predator-escape sequence the assessment stage is followed by an escape response (e.g., flight, concealment, fighting). The cardiac changes that occur during these three common stages will be studied in both standard laboratory test chambers and simulated natural environments designed for each of the species to be studied. The second phase will employ specific pharmacological treatments to assess the underlying physiological mechanisms responsible for the various changes in heart rate that occur during the predication and predator-escape sequences. Subsequent research will attempt to relate those autonomic changes to attention and information processing. The third phase will focus on the role of the cardiac and behavioral responses occurring during the various stages of the predation and predator-avoidance sequences on attention and information processing. These results will be interpreted in terms of their significance for contemporary theories of attention and information processing in human subjects.

拟议研究的长期目标是提高我们的 了解定向反应和防御反应的作用 人类的注意力和信息处理。 过去几 数十年来对人类受试者的广泛研究未能解决许多问题 与这个问题相关的基本问题。 目的 拟议的研究旨在对方向和方向进行系统分析 来自三个不同门的动物受试者的防御反应 分析伴随的自主神经系统活动的变化 这些反应，并研究这些反应对注意力的影响 信息处理属于三类动物。 实现一个 更全面地了解定向和防御反应的功能 在多种动物物种中可能有助于我们了解 这些人类注意力和信息处理的反应。 拟议研究的第一阶段将系统地考察 对中性、猎物和捕食者刺激的心脏和行为反应 在某些两栖动物（例如 Bufo marinus）、爬行动物（例如 Sceleporus）中 poinsetti）和哺乳动物（Sigmodon hispidus）。 虽然特别 所选择的物种在许多方面有所不同，它们都受到影响 被相同的捕食者捕食并消耗相似的猎物物种。 这 将使我们能够研究心脏和行为反应 不同的动物物种对相同的猎物和捕食者的刺激 真实或模拟的猎物和捕食者的形式。 其中一大焦点 拟议的研究将记录心率的变化 发生在捕食和捕食者逃脱的各个阶段。 这 这些序列的前三个阶段是相同的，由 (1) 组成 检测，(2) 识别，(3) 评估。 在掠夺中 评估阶段之后是捕获响应的顺序（例如， 接近和/或攻击）。 在捕食者逃脱序列中，评估 阶段之后是逃避反应（例如，逃跑、隐藏、 斗争）。 这三种常见情况下发生的心脏变化 将在标准实验室测试室和 为每个物种设计的模拟自然环境 研究过。 第二阶段将采用特定的药物治疗 评估潜在的生理机制 预测期间发生的心率的各种变化 捕食者逃脱序列。 后续研究将尝试联系 注意力和信息处理的自主变化。 第三阶段将重点关注心脏和行为的作用 捕食的各个阶段发生的反应 关于注意力和信息处理的捕食者躲避序列。 这些结果将根据其意义来解释 人类注意力和信息处理的当代理论 科目。
