在注意力的经典理论中,无意识自动过程被认为独立于更高层次的注意力影响。在这里,我们提出,无意识的处理依赖于注意力的增强任务一致的处理途径,通过动态调制的功能之间的通信的大脑区域。使用功能性磁共振成像,我们测试了我们的模型与潜意识启动词汇决策任务之前的诱导任务准备一个语义或感知任务集。与腹侧枕颞叶(vOT)和下额叶皮层(已知参与语义处理的大脑区域)的知觉诱导相比,语义后阈下语义启动显著更大。vOT的功能连接模式根据诱导任务而变化,并成功地预测了行为和神经启动的大小。总之,这些发现支持了这样一种观点,即通过任务集动态建立功能网络是无意识处理的注意力控制的重要机制。©2014 Wiley Periodicals,Inc.
In classical theories of attention, unconscious automatic processes are thought to be independent of higher‐level attentional influences. Here, we propose that unconscious processing depends on attentional enhancement of task‐congruent processing pathways implemented by a dynamic modulation of the functional communication between brain regions. Using functional magnetic resonance imaging, we tested our model with a subliminally primed lexical decision task preceded by an induction task preparing either a semantic or a perceptual task set. Subliminal semantic priming was significantly greater after semantic compared to perceptual induction in ventral occipito‐temporal (vOT) and inferior frontal cortex, brain areas known to be involved in semantic processing. The functional connectivity pattern of vOT varied depending on the induction task and successfully predicted the magnitude of behavioral and neural priming. Together, these findings support the proposal that dynamic establishment of functional networks by task sets is an important mechanism in the attentional control of unconscious processing.Hum Brain Mapp 35:5500–5516, 2014. ©2014 Wiley Periodicals, Inc.
