Recent studies have consistently demonstrated that conscious perception interacts with exogenous attentional orienting, but it can be dissociated from endogenous attentional orienting (Chica Lasaponara, et al., 2011; Wyart & Tallon-Baudry, 2008). It has been hypothesized that enhanced conscious processing at exogenously attended locations results from a synergistic action of spatial orienting, bottom-up activation, and phasic alerting induced by the abrupt onset of the exogenous cue (Chica, Lasaponara, et al., 2011). Instead, as endogenous cues need more time to be interpreted, the phasic alerting they produce may have dissipated when the target appears. Furthermore, endogenous cues presumably elicit a weak bottom-up activation at the cued location. Consistent with these hypotheses, we observed that endogenous attention modulated conscious perception, but only when phasic alerting or bottom-up activation was increased. Results are discussed in the context of recent theoretical models of consciousness (Dehaene, Changeux, Naccache, Sackur, & Sergent, 2006).
最近的研究一致表明，意识知觉与外源性注意定向相互作用，但它可以与内源性注意定向分离（Chica Lasaponara 等人，2011 年；Wyart 和 Tallon-Baudry，2008 年）。据推测，在外源性注意位置增强的意识加工是由空间定向、自上而下的激活以及外源性线索突然出现引起的相位警觉协同作用的结果（Chica、Lasaponara 等人，2011 年）。相反，由于内源性线索需要更多的时间来解释，当目标出现时，它们产生的相位警觉可能已经消散。此外，内源性线索可能会在提示位置引起微弱的自下而上的激活。这些假设与我们的观察结果一致，即内源性注意调节意识知觉，但只有在相位警觉或自下而上的激活增加时才会调节。结果在最近的意识理论模型（Dehaene、Changeux、Naccache、Sackur 和 Sergent，2006 年）的背景下进行了讨论。
