Manuel LealResearch Starter Grant "Teasing apart the contribution of color and motion toward the efficiency of visual signal displays"Lay abstract:Visual signals used during social interactions commonly incorporate motion and color in their design. These signals are used to transmit information, which influences the behavior of the interacting animals. Surprisingly, we know very little about the effect of color and motion in signal detection, and even less about how changes of one of the signal components influences signal efficiency (i.e., detection ability) and content (i.e., information ability). The multicomponent signal hypothesis predicts that an increase in efficiency is achieved by the simultaneous stimulation of two or more sensory pathways, resulting in an increase in the ability of the receiver to detect and recognize the signal. This study will examine the contribution of motion and color patterns to the efficiency of visual signals in the lizard Anolis krugi. Experimental manipulations of the signal design, motion, and color pattern will be conducted to test the role of these components on signal efficiency and signal content.The proposed research will be one of only a handful of studies to directly test the multiple signal hypothesis in visual signals. The findings will contribute not only to basic scientific knowledge in the area of animal communication, but also to improving our knowledge of the interaction between color and motion on visual perception. Furthermore, the fundamental principles which control how detectable visual stimuli are in lizards are similar to those which control visual target visibility in vertebrate visual systems; thus, these studies can provide important insights into the ways in which vertebrate visual systems process moving, colored signals.

Manuel LealResearch Starter Grant“将颜色和运动对视觉信号显示效率的贡献分开“Lay abstract：在社交互动中使用的视觉信号通常在其设计中包含运动和颜色。这些信号被用来传递信息，影响相互作用的动物的行为。令人惊讶的是，我们对信号检测中的颜色和运动的影响知之甚少，甚至更不了解信号分量之一的变化如何影响信号效率（即，检测能力）和内容（即，信息能力）。多分量信号假说预测，通过同时刺激两个或多个感觉通路来实现效率的增加，从而增加接收器检测和识别信号的能力。本研究将探讨的贡献，运动和颜色模式的效率，视觉信号的蜥蜴Anolis krugi。实验操作的信号设计，运动和颜色模式将进行测试的信号效率和信号content.The拟议的研究将是少数几个研究之一，直接测试在视觉信号的多信号假设这些组件的作用。这些发现不仅有助于动物交流领域的基础科学知识，而且有助于提高我们对颜色和运动之间相互作用的认识。此外，控制如何检测视觉刺激在蜥蜴的基本原则是相似的，在脊椎动物视觉系统中控制视觉目标的可见性，因此，这些研究可以提供重要的见解，脊椎动物视觉系统的过程中移动，彩色信号的方式。
