时间频率是听觉和触觉的基本感觉维度。在听觉中，时间频率的分析对于语音和音乐感知是必要的;在触觉中，振动信号的频谱分析涉及纹理感知和通过工具感知环境。撞击在耳朵上的环境振荡通常被认为独立于撞击在皮肤上的振荡而被处理。在这里，我们展示了频率通道在听觉和触觉上的感知联系。在一系列的心理物理学实验中，我们证明了听觉刺激干扰触觉频率感知系统的方式。具体而言，触觉频率辨别任务的性能受损时，听觉干扰与触觉刺激，但只有当听觉和触觉刺激的频率是相似的。无论干扰物是纯音还是带通噪声，都可以观察到频率相关的干扰效应，因此产生这种效应不需要音高的听觉感受。重要的是，干扰，强烈损害频率的歧视不干扰触觉强度的判断。不同模态之间的这种令人惊讶的特定串扰反映了基本感觉维度的超模态表征的重要性。
Temporal frequency is a fundamental sensory dimension in audition and touch. In audition, analysis of temporal frequency is necessary for speech and music perception; in touch, the spectral analysis of vibratory signals has been implicated in texture perception and in sensing the environment through tools. Environmental oscillations impinging upon the ear are generally thought to be processed independently of oscillations impinging upon the skin. Here, we show that frequency channels are perceptually linked across audition and touch. In a series of psychophysical experiments, we demonstrate that auditory stimuli interfere with tactile frequency perception in a systematic manner. Specifically, performance on a tactile frequency-discrimination task is impaired when an auditory distractor is presented with the tactile stimuli, but only if the frequencies of the auditory and tactile stimuli are similar. The frequency-dependent interference effect is observed whether the distractors are pure tones or band-pass noise, so an auditory percept of pitch is not required for the effect to be produced. Importantly, distractors that strongly impair frequency discrimination do not interfere with judgments of tactile intensity. This surprisingly specific crosstalk between different modalities reflects the importance of supramodal representations of fundamental sensory dimensions.
