由两个不同相位的叠加正弦波组成的复杂振动触觉波形呈现在指尖上，观察者做出“相同-不同”的判断。结果发现，低频（10 Hz +30 Hz）波形彼此可区分，而高频（100 Hz +300 Hz）振动的区分度较差。高频适应并没有损害歧视的低频波形，表明RA通道介导的歧视。低频适应损害歧视的高频刺激，这表明RA通道同样介导的适度水平的性能观察到的适应刺激的情况下。结果表明，该通道对复杂波形进行时间编码。提出了一种简单的低频波形识别模型。用高频复合波形获得的结果与PC通道随时间积分刺激能量的假设是相容的。
Complex vibrotactile waveforms consisting of two superimposed sinusoids at varying phases were presented to the fingertip, and observers made "same-different" judgments. It was found that the low-frequency (10Hz+30Hz) waveforms were discriminable from one another while discrimination of the high-frequency (100Hz+300Hz) vibrations was poor. High-frequency adaptation did not impair discrimination of the low-frequency waveforms, suggesting that the RA channel mediated discrimination. Low-frequency adaptation impaired discrimination of the high-frequency stimuli, suggesting that the RA channel likewise mediated the modest level of performance observed in the absence of an adapting stimulus. The results indicate that this channel encodes complex waveforms temporally. A simple model for low-frequency waveform discrimination is proposed. The results obtained with the high-frequency complex waveforms are compatible with the hypothesis that the PC channel integrates stimulus energy over time.
