Abstract
In 3 chimpanzees, trained to press a key when (and only when) an auditory stimulus was given, and tested with tones from a, Pierce magnetostriction oscillator, ranging in frequency 14,400-37,500 cycles per sec. (C.P.S.), the 50% thresholds ranged 26,000-33,000 c.p.s. In 3 children, tested likewise, no response to any frequencies above 25,000 c.p.s. was obtained. Difference in auditory sensitivity between man and other primates is probably a result of the latter''s relative superiority in reception of high frequency sounds.This publication has 2 references indexed in Scilit:
