我们通过刺激驱动的脑振荡反应，即所谓的稳态诱发电位(SSEP)，研究了通道间注意对视觉和触觉刺激同时加工的影响。为此，我们对视觉刺激(7.5赫兹)和触觉刺激(20赫兹)进行了频率标记，并在逐一试验的基础上提示参与者注意视觉或触摸，以执行线索通道中的检测任务。由刺激驱动的SSEP包括刺激频率跟随(即基频)和倍频(即二次谐波)反应。我们观察到，对视觉的跨模式注意增加了视觉SSEP的基频成分的幅度和相位同步，而二次谐波成分仅表现出相位同步的增加。相反，通道间对触摸的注意增加了二次谐波的SSEP幅度，但不增加基频的SSEP幅度，而使两种反应的相位同步性不受影响。我们的结果表明，通道间注意通常会影响视觉和触觉中的同时刺激加工，从而将早期的视听发现扩展到视觉-触觉刺激情景。然而，结果的模式表明，在视觉和触觉刺激加工中，通道间注意影响的神经实现存在差异。
We investigated effects of inter-modal attention on concurrent visual and tactile stimulus processing by means of stimulus-driven oscillatory brain responses, so-called steady-state evoked potentials (SSEPs). To this end, we frequency-tagged a visual (7.5 Hz) and a tactile stimulus (20 Hz) and participants were cued, on a trial-by-trial basis, to attend to either vision or touch to perform a detection task in the cued modality. SSEPs driven by the stimulation comprised stimulus frequency-following (i.e. fundamental frequency) as well as frequency-doubling (i.e. second harmonic) responses. We observed that inter-modal attention to vision increased amplitude and phase synchrony of the fundamental frequency component of the visual SSEP while the second harmonic component showed an increase in phase synchrony, only. In contrast, inter-modal attention to touch increased SSEP amplitude of the second harmonic but not of the fundamental frequency, while leaving phase synchrony unaffected in both responses. Our results show that inter-modal attention generally influences concurrent stimulus processing in vision and touch, thus, extending earlier audio-visual findings to a visuo-tactile stimulus situation. The pattern of results, however, suggests differences in the neural implementation of inter-modal attentional influences on visual vs. tactile stimulus processing.
