神经系统能够完全处理通常在任何时刻撞击感觉器官的信息的一小部分。注意力提供了一种重要的机制，可以选择要广泛处理的某些信息，尽管它往往限制了对其他信息的处理。两个主要问题是：注意力是否可以被引导到单一通道中的特定刺激，例如，对产生甜味的味觉刺激和产生酸味的味觉刺激？注意力是否可以指向特定的化学感觉方式，例如，味觉成分与嗅觉成分的味道？有证据表明，人们至少有一定的能力，有选择地参加特定的化学感觉方式和风味刺激。对单个模态的选择性注意可以反映对该模态中的神经活动的优先监测，而对模态内的特定刺激的选择性注意可以表示对模态中对所关注的刺激最敏感的那些神经元的神经活动的优先监测。
The nervous system is capable of fully processing only a small fraction of the information typically impinging on the sense organs at any moment. Attention provides an important mechanism for selecting some information to be processed extensively, albeit often limiting the processing of other information. Two main questions are: Can attention be directed toward particular stimuli within a single modality, for example, toward sweet-producing versus sour-producing gustatory stimuli? Can attention be directed toward a particular chemosensory modality, for example, toward gustatory versus olfactory constituents of flavors? Evidence suggests that people have at least some ability to attend selectively to particular chemosensory modalities and flavor stimuli. Selective attention to a single modality may reflect the preferential monitoring of neural activity in that modality, whereas selective attention to particular stimuli within a modality may represent preferential monitoring of neural activity of those neurons in the modality that are most sensitive to the attended stimuli.
