这些实验的目的是检验眼点和刺激运动作为系带蛇抗捕食者反应的中介的效果。在实验一中，13条6-8周龄的东方系带蛇(Thamnopits Sirtalis)面对一系列威胁模型，这些模型的眼睛形状各不相同(人造玻璃眼睛、圆形黑点、细长的黑条或没有眼点)。模型引发的攻击次数有显著差异，具有逼真玻璃眼睛的模型引发的攻击最多。在实验2中，我们考察了12-16周龄的12条吊袜带蛇不稳定和一致的刺激运动对防御行为的影响。与以规则速度摆动的模型相比，蛇对不规则移动的模型提供了更多的打击。
The purpose of these experiments was to examine the effects of eye spots and stimulus movement as mediators of antipredator responses in garter snakes. In Experiment 1, 13 Eastern garter snakes (Thamnophis sirtalis) at 6-8 weeks of age were confronted with a series of threatening models that varied in the configuration of the eyes (artificial glass eyes, circular black spots, elongated black bars, or no eyespots). There were significant differences in the number of strikes elicited by the models, and the model with realistic glass eyes elicited the most strikes. In Experiment 2, we examined the effects of erratic and consistent stimulus movement on defensive behavior in 12 garter snakes at 12-16 weeks of age. The snakes delivered significantly more strikes to an erratically moving model than to a model oscillated at a regular rate.
