注意的神经影像学研究往往集中在刺激表征和视觉皮层自上而下的选择机制之间的相互作用。目前对视觉区域以外的干扰刺激的神经表征以及语言加工区域内刺激之间的相互作用知之甚少。在本研究中，参与者同时查看在周边位置的线条画，而在MRI扫描仪。这些图片中描绘的物体的名称要么在语音上相关（即共享相同的辅音-元音起始结构），要么不相关。注意力要么指向这些图片之一的语言特性，要么指向固定点（即远离图片）。未被注意图片的语音表征在颞后上级回、额下回和小脑皮层都能被检测到。在某些情况下，被忽略的干扰图片的名称检索的语言区域。这意味着对特定位置的选择性注意在早期感知阶段并没有完全过滤掉干扰刺激的表征。
Neuroimaging studies of attention often focus on interactions between stimulus representations and top-down selection mechanisms in visual cortex. Less is known about the neural representation of distractor stimuli beyond visual areas, and the interactions between stimuli in linguistic processing areas. In the present study, participants viewed simultaneously presented line drawings at peripheral locations, while in the MRI scanner. The names of the objects depicted in these pictures were either phonologically related (i.e. shared the same consonant-vowel onset construction), or unrelated. Attention was directed either at the linguistic properties of one of these pictures, or at the fixation point (i.e. away from the pictures). Phonological representations of unattended pictures could be detected in the posterior superior temporal gyrus, the inferior frontal gyrus, and the insula. Under some circumstances, the name of ignored distractor pictures is retrieved by linguistic areas. This implies that selective attention to a specific location does not completely filter out the representations of distractor stimuli at early perceptual stages.
