Foreknowledge of target stimulus features improves visual search performance as a result of 'feature-based attention' (FBA). Recent studies have reported that 'feature-based expectation' (FBE) also heightens decision sensitivity. Superficially, it appears that the latter work has simply rediscovered (and relabeled) the effects of FBA. However, this is not the case. Here we explain why.
目标刺激特征的先验知识通过“基于特征的注意”（FBA）提高了视觉搜索性能。最近的研究表明，“基于特征的预期”（FBE）也提高了决策敏感性。表面上看，后一项工作似乎只是重新发现（并重新标记）了 FBA 的效果。然而，事实并非如此。在这里，我们解释原因。
