<p>测试蜥蜴的感官能力已经很难，而在很大程度上是一项繁琐而艰苦的过程。这些困难源于找到正确的增强剂或建立一个功能的协议。在这里，我建立了一个成功的协议，在其中测试蜥蜴运动知觉。此过程可能也适用于测试其他的视觉特征以及其他感官机制。此外，此过程可能适用于其他物种。这个协议的有效性，不仅使我们了解自然的行为，而是利用其他的科学努力的典范蜥蜴行为。 </p>

testing visual sensitivity to the speed and direction of motion in lizards

<p class="jove_content">任何物种的视觉灵敏度的测试提供基本信息的行为，演变和生态。然而，视觉系统的具体功能测试功能的应用提供了更多的经验证据。感觉系统的调查，提供有关的感觉能力，学习和记忆能力的信息，并建立了已知的基本行为方式来衡量偏差（薄瑞光，1977年）。然而，不像哺乳动物或鸟类的系统，在爬行动物的学习和记忆能力的测试是困难的。此外，使用的感官能力的心理物理学措施操作性范式，同样是困难的。从历史上看，爬行动物物种的回应不佳空调试验，因为动机，生理，代谢和基本生物学特性有关的问题。在这里，我演示了一个操作性的范例使用一种新的模式，蜥蜴，张学友龙（Amphibolurus muricatus）和描述如何测试周边的敏感性显着的速度和运动特性。这种方法使用了一个创新的方法，以评估学习和蜥蜴感觉能力。我采用随机点kinematograms（RDKs）来测量灵敏度，速度，操纵信号强度水平的改变在一个连贯的方向移动点的比例。 RDKs没有代表了生物学上有意义的刺激，从事视觉系统，是一个经典的心理物理学的工具，用来衡量在人类和其它动物的敏感性。在这里，RDKs显​​示使用三个视频播放系统的蜥蜴。蜥蜴，选择他们认为点移动的方向（左或右）。选择适当的方向是加强具有重要生物学意义的猎物的刺激，通过电脑动画无脊椎动物模拟。 </p>
