一些眼部疾病，尤其是黄斑变性，会导致中央视力丧失（CVL），损害目标驱动的注意力引导。 CVL 是否也会影响内隐的、经验驱动的注意力？我们研究了模拟的中心暗点如何影响年轻人对经常包含视觉搜索目标的位置进行优先排序的能力（位置概率学习）。参与者在干扰字母“L”中搜索目标“T”，该目标“T”在一个屏幕象限中出现的频率高于其他象限。为了消除对目标位置统计学习和注意力引导的潜在损害，两个实验分别包括有和没有模拟暗点的搜索。实验 1 成功诱导了无暗点阶段的概率学习。当参与者后来在有和没有模拟暗点的情况下进行搜索时，他们在无暗点和无暗点搜索中都表现出持续的、统计上相同的空间偏差。实验 2 训练了具有中心暗点的参与者。虽然实验 1 的参与者获得了概率学习，而不管他们自我报告是否意识到目标的位置概率，但在实验 2 中，只有意识到的参与者才学会将注意力偏向高概率区域。同样，带有暗点的学习会影响有意识但没有意识的参与者的无暗点搜索。总之，这些结果表明，模拟的中央视觉损失会干扰隐式学习位置概率学习的获取，支持中央视觉在隐式空间注意偏差中的作用。
Some eye diseases, especially macular degeneration, can cause central vision loss (CVL), impairing goal-driven guidance of attention. Does CVL also affect implicit, experience-driven attention? We investigated how simulated central scotomas affected young adults' ability to prioritize locations frequently containing visual search targets (location probability learning). Participants searched among distractor letter 'L's for a target 'T' that appeared more often in one screen quadrant than others. To dissociate potential impairments to statistical learning of target locations and attentional guidance, two experiments each included search with and without simulated scotomas. Experiment 1 successfully induced probability learning in a no-scotoma phase. When participants later searched both with and without simulated scotomas, they showed persistent, statistically equivalent spatial biases in both no-scotoma and scotoma search. Experiment 2 trained participants with a central scotoma. While Experiment 1's participants acquired probability learning regardless of their self-reported awareness of the target's location probability, in Experiment 2 only aware participants learned to bias attention to the high probability region. Similarly, learning with a scotoma affected search with no scotoma in aware but not unaware participants. Together, these results show that simulated central vision loss interferes with the acquisition of implicitly learned location probability learning, supporting a role of central vision in implicit spatial attentional biases.
