Six kittens were tested in a 2-choice maze to determine if they would execute directional approach responses to an auditory stimulus. Tests were done at various postnatal ages (4-10, 11-17, 18-24, and 25-31 days) and comparison was made with responses of 5 kittens tested without auditory stimulation. At the earliest ages no evidence was seen for auditory approach responses but by 18-24 days consistent approch responses were found.
六只小猫在一个双选迷宫中接受测试，以确定它们是否会对听觉刺激做出定向趋近反应。测试在不同的出生后年龄（4 - 10天、11 - 17天、18 - 24天和25 - 31天）进行，并与五只未接受听觉刺激测试的小猫的反应进行比较。在最早的年龄阶段，没有发现听觉趋近反应的证据，但到18 - 24天时，发现了一致的趋近反应。
