精细调整的感觉功能通常表征熟练的个体。虽然许多研究表明，在神经和行为水平的熟练的个人增强的单峰感觉功能，很少有人知道他们的多感觉的相互作用功能，特别是多感觉整合和选择性注意，涉及来自多个感觉器官的信息的意志控制。在当前的研究中，钢琴专家和音乐未经训练的个体在不同条件下在听觉和体感模式下执行五组强度辨别任务：（1）听觉刺激，（2）体感刺激，（3）一致的听觉和体感刺激（即，多感觉整合），（4）听觉和任务无关的躯体感觉刺激，和（5）躯体感觉和任务无关的听觉刺激。在第四和第五种情况下，参与者被指示忽略与任务无关的刺激，并注意与任务相关的刺激（即，选择性注意）。虽然只有钢琴家在条件（3）中的辨别知觉优于个体单峰条件中的较好条件，但与任务无关的体感刺激使钢琴家的听觉辨别能力比非音乐家更差。这些研究结果表明，独特的多感官互动专家钢琴家，这使得钢琴家有效地整合听觉和体感信息，但加剧了自上而下的选择性抑制的体感信息在听觉处理。
Fine-tuned sensory functions typically characterize skilled individuals. Although numerous studies demonstrated enhanced unimodal sensory functions at both neural and behavioral levels in skilled individuals, little is known about their multisensory interaction function, especially multisensory integration and selective attention that involve volitional control of information derived from multiple sensory organs. In the current study, expert pianists and musically untrained individuals performed five sets of intensity discrimination tasks at the auditory and somatosensory modalities with different conditions: (1) auditory stimulus, (2) somatosensory stimulus, (3) congruent auditory and somatosensory stimuli (i.e., multisensory integration), (4) auditory and task-irrelevant somatosensory stimuli, and (5) somatosensory and task-irrelevant auditory stimuli. In the fourth and fifth conditions, participants were instructed to ignore a task-irrelevant stimulus and to pay attention to a task-relevant stimulus (i.e., selective attention), respectively. While the discrimination perception was superior in the condition (3) compared to the better one of the individual unimodal conditions only in the pianists, the task-irrelevant somatosensory stimulus worsened the auditory discrimination more in the pianists than the nonmusicians. These findings indicate unique multisensory interactions in expert pianists, which enables pianists to efficiently integrate the auditory and somatosensory information, but exacerbates top-down selective inhibition of somatosensory information during auditory processing.
