之前对各种非人类动物的研究表明，它们拥有一种进化的捕食者识别机制，这种机制指定了反复出现的威胁的外观。我们在三个实验中使用偏好注视和习惯化范式来调查5个月大的人类婴儿是否具有蜘蛛的感知模板，该模板概括为现实世界中的蜘蛛图像。第四个实验评估了5个月大的婴儿是否有一个感知模板来接受非威胁性的生物刺激(即一朵花)。这些结果支持了一种假设，即人类和其他物种一样，可能拥有一种认知机制，可以检测出在整个进化史上可能有害的特定动物。
Previous studies with various non-human animals have revealed that they possess an evolved predator recognition mechanism that specifies the appearance of recurring threats. We used the preferential looking and habituation paradigms in three experiments to investigate whether 5-month-old human infants have a perceptual template for spiders that generalizes to real-world images of spiders. A fourth experiment assessed whether 5-month-olds have a perceptual template for a non-threatening biological stimulus (i.e., a flower). The results supported the hypothesis that humans, like other species, may possess a cognitive mechanism for detecting specific animals that were potentially harmful throughout evolutionary history.
