1. 一个声音必须是既可定位又可识别的，才能对这个声音产生积极的趋声性，这一假设在双斑蟋蟀中得到了验证。 拴系的雌性动物可以在非补偿跑步机上行走。 歌曲是从两个扬声器播放的，一个放在旁边，另一个放在蟋蟀的正上方，这样蟋蟀就可以定位来自侧面的声音，而不是来自顶部扬声器的声音。 首先从侧面扬声器播放具有无效脉冲（音节）周期的呼叫歌曲啁啾。 这些啁啾未能引起积极的趋声性。 当这些无效的啁啾声与顶部扬声器播放的具有适当脉冲周期的啁啾声交织时，雌性开始走向侧面扬声器。 因此，对于一个声音来说，不一定要同时被定位和识别（re：脉冲周期），才能发生对这个声音的积极趋声性。 进行了额外的实验来测试啁啾节奏如何影响趋声性。 从侧面扬声器播放的无效（缓慢）啁啾未能引起趋声性。 然而，当这些缓慢的，无效的啁啾声与顶部扬声器播放的音调突发交织时，就会引起趋声性。 这进一步证明了呼唤歌曲的时间属性的相互作用在诱发趋声性的重要性。
1. The hypothesis that a sound must be both localizable and recognizable for positive phonotaxis towards this sound to occur was tested in Gryllus bimaculatus.2. Tethered females were allowed to walk on a non-compensating treadmill. Songs were played from two loudspeakers, one positioned to the side and another positioned directly above the cricket, so crickets could localize sounds from the side but not from the top speaker.3. Calling song chirps with an ineffective pulse (syllable) period were first played from the side speaker. These chirps failed to elicit positive phonotaxis. When these ineffective chirps were interleaved with top speaker playbacks of chirps that had an appropriate pulse period, females began to walk toward the side speaker. So it is not necessary for a sound to be both localized and recognized (re: pulse period) for positive phonotaxis to this sound to occur.4. Additional experiments were run to test how chirp rhythm affected phonotaxis. Ineffective (slow) chirps played from the side speaker failed to elicit phonotaxis. However, phonotaxis was elicited when these slow, ineffective chirps were interleaved with tone bursts played from the top speaker. This further demonstrates the importance of the interaction of calling song temporal properties in eliciting phonotaxis.
