The finger-withdrawal reaction time (RT) of 22 normal-hearing young adults was measured to 40 presentations of test tones of .5 kc/s and of .4 kc/s at 50 db SPL. An adapting tone of .4 or .5 kc/s at 50 db SPL was then presented, and after 7 min, RTs were collected to a series of 40 test tones as in the pre-adaptation procedure. The adapting tone-test tone order of .4-.5 kc/s, respectively, and the reverse order, were counterbalanced among Ss. In this study, as reported previously (Davis and Weiler, Brit. J. Audiol., 1976, 10, 102-106), RT changes were significant as a function of adaptation, but only in the order .5-.4 kc/s. Further study would be required to determine whether cochlear or more central processes are responsible for adaptation at .5 kc/s affecting RT at .4 kc/s, but for adaptation at .4 kc/s not significantly affecting RT at .5 kc/s.
对22名听力正常的年轻成年人进行了手指撤离反应时间（RT）测量，测量他们对50分贝声压级下频率为0.5千赫兹和0.4千赫兹的测试音各40次呈现的反应。然后呈现50分贝声压级下频率为0.4或0.5千赫兹的适应音，7分钟后，按照适应前的程序，收集他们对一系列40次测试音的反应时间。适应音 - 测试音的顺序分别为0.4 - 0.5千赫兹以及相反顺序，在受试者之间进行了平衡。在本研究中，如先前报道（戴维斯和韦勒，《英国听力学杂志》，1976年，第10卷，第102 - 106页），反应时间的变化作为适应的函数是显著的，但仅在0.5 - 0.4千赫兹的顺序中。需要进一步研究来确定是耳蜗过程还是更中枢的过程导致在0.5千赫兹的适应影响了在0.4千赫兹时的反应时间，而在0.4千赫兹的适应对在0.5千赫兹时的反应时间没有显著影响。
