研究了蟋蟀雌性在运动补偿器上的趋声反应，以确定对物种识别很重要的雄性鸣叫的时间参数。两种同域分布的物种（Teleogryllus commodus，T. oceanicus），它们在鸣叫的啁啾和颤音部分显示不同的音节周期。根据他们的回答T。康莫德斯女性表现出两个时间过滤器的音节周期，这是调整到特定的音节周期发生在啁啾和颤音。对于歌曲识别，必须激活两个过滤器，并且对于两个过滤器，至少需要三到五个连续的音节周期。与此相反，T.雌性海洋生物只显示出一个与雄性鸣叫声的啁啾部分相对应的急剧调谐的滤波器。这个过滤器对于呼叫歌曲识别是足够的。颤音部分的音节周期也影响了呼叫歌曲的识别，但这些只起了很小的作用。载波频率也是重要的积极的趋声性。T. commodus雌性主要基于中枢神经处理，而T.海洋鱼类的外周频率滤波和中央时间滤波都很重要。
The phonotactic response of cricket females was investigated on a locomotion compensator to determine the temporal parameters of the male's calling song which are important for species recognition. Two sympatric species (Teleogryllus commodus, T. oceanicus) that show different syllable periods in the chirp and trill parts of their calling songs were used. By their responses T. commodus females exhibited two temporal filters for syllable periods, which were tuned to the species-specific syllable periods occurring during chirp and trill. For song recognition both filters had to be activated and for both a minimum number of three to five consecutive syllable periods was necessary. In contrast, T. oceanicus females showed only one sharply tuned filter corresponding to the chirp part of the male's calling song. This filter was sufficient for calling song recognition. Syllable periods of the trill part also influenced calling song recognition, but these played only a minor role. Carrier frequency was also important for positive phonotaxis. Calling song recognition by T. commodus females is largely based on central nervous processing, while for T. oceanicus both peripheral frequency filtering and central temporal filtering is important.
