多感觉过程是支撑感知、认知、学习和行为的基础。如何以及何时从不同的感官形式的刺激是集成的，而不是作为单独的实体处理是知之甚少。我们回顾了如何相对依赖于刺激特性与学会协会动态形状多感觉过程。我们说明了两个时间尺度的多感官功能的动态性：一个长期的，在整个生命周期中运作，一个短期的，在学习新的多感官关系。此外，我们强调任务突发事件的重要性。我们的结论是，这些高度动态的多感官过程，刺激特征和学会协会的相对权重的基础上，提供了稳定性和灵活性，在广泛的时间尺度的大脑功能。
Multisensory processes are fundamental in scaffolding perception, cognition, learning and behaviour. How and when stimuli from different sensory modalities are integrated rather than treated as separate entities is poorly understood. We review how the relative reliance on stimulus characteristics versus learned associations dynamically shapes multisensory processes. We illustrate the dynamism in multisensory function across two timescales: one long-term that operates across the lifespan and one short-term that operates during the learning of new multisensory relations. In addition, we highlight the importance of task contingencies. We conclude that these highly dynamic multisensory processes, based on the relative weighting of stimulus characteristics and learned associations, provide both stability and flexibility to brain functions over a wide range of temporal scales.
