Wang，Cavanagh，and绿色（1994）证明了在熟悉的干扰物中搜索不熟悉的目标（U-F搜索）时的弹出效应，并认为目标和干扰物之间的熟悉度差异在决定搜索效率方面的重要性。在四个实验中，我们探索了这一发现的普遍性。实验1比较了各种目标干扰对的搜索效率。在实验2、3和4中，我们使用汉字及其变换作为目标和干扰词，并比较了中国和非中国参与者的搜索性能。我们证明，搜索不对称性和搜索效率的U-F条件下的存在下，熟悉和不熟悉的刺激之间的低级别的功能差异的影响。我们的研究结果表明，干扰词的熟悉程度，而不是目标和干扰词之间的熟悉程度差异，决定搜索效率。我们还记录了一个违反直觉的熟悉自卑效应，这表明搜索刺激的知识，有时，是有害的搜索性能。
Wang, Cavanagh, and Green (1994) demonstrated a pop-out effect in searching for an unfamiliar target among familiar distracters (U-F search) and argued for the importance of a familiarity difference between the target and the distracters in determining search efficiency. In four experiments, we explored the generality of that finding. Experiment 1 compared search efficiency across a variety of target-distracter pairs. In Experiments 2, 3, and 4, we used Chinese characters and their transforms as targets and distracters and compared search performance between Chinese and non-Chinese participants. We demonstrated that search asymmetry and search efficiency in the U-F condition are influenced by the presence of low-level feature differences between the familiar and the unfamiliar stimuli. Our findings suggest that the familiarity of the distracters, rather than the familiarity difference between the target and the distracters, determines search efficiency. We also documented a counterintuitive familiarity-inferiority effect, suggesting that knowledge of search stimuli may, sometimes, be detrimental to search performance.
