我们研究了马是否表现出更大的反应，一个新的刺激在左边相比，右单眼视野，以及是否存在人口偏见逃避转向时，同样的刺激提出双目。家马（N = 30）进行了三次测试，一个人在五米外打开雨伞，然后接近。测量每匹马在停下来之前离开的距离。距离是最大的方法在左侧，表明右半球控制的飞行行为，因此遵循相同的模式，以前在其他物种。当单目呈现的顺序被认为是一个不对称的检测。最初在左侧测试的马表现出更大的反应性左侧的方法，而马测试的右侧首先显示没有侧差异的反应。也许左半球对飞行反应的抑制使马知道刺激不构成威胁，并将此信息转移到右半球。不存在人口偏见的方向逃跑转向，但马转向右时，从前面接近被发现表现出更长的飞行距离比那些转向左边。
We investigated whether horses display greater reactivity to a novel stimulus presented in the left compared to the right monocular visual field, and whether a population bias exists for escape turning when the same stimulus was presented binocularly. Domestic horses ( N = 30) were tested on three occasions by a person opening an umbrella five metres away and then approaching. The distance each horse moved away before stopping was measured. Distance was greatest for approach on the left side, indicating right hemisphere control of flight behaviour, and thus followed the same pattern found previously in other species. When order of monocular presentation was considered, an asymmetry was detected. Horses tested initially on the left side exhibited greater reactivity for left approach, whereas horses tested on the right side first displayed no side difference in reactivity. Perhaps left hemisphere inhibition of flight response allowed horses to learn that the stimulus posed no threat and this information was transferred to the right hemisphere. No population bias existed for the direction of escape turning, but horses that turned to the right when approached from the front were found to exhibit longer flight distances than those that turned to the left.
