使用视觉搜索任务，我们探讨了行为是如何受到视觉和语义信息的影响。我们记录了参与者在一组个位数（0-9）中搜索单个目标数字时的眼球运动。我们检查了固定各种干扰物的概率作为两个关键维度的函数：目标和每个干扰物之间的视觉相似性，以及语义相似性（即，数字距离）。视觉相似性估计，获得了使用多维尺度的基础上独立的观察员相似性评级。线性混合效应模型表明，视觉和语义相似性都会影响干扰物被固定的概率。然而，视觉相似性的效果是远远大于语义相似性的效果。最后，我们讨论了使用这种新的方法的潜在价值和简单和复杂的视觉搜索显示的影响。
Using a visual search task, we explored how behavior is influenced by both visual and semantic information. We recorded participants' eye movements as they searched for a single target number in a search array of single-digit numbers (0-9). We examined the probability of fixating the various distractors as a function of two key dimensions: the visual similarity between the target and each distractor, and the semantic similarity (i.e., the numerical distance) between the target and each distractor. Visual similarity estimates were obtained using multidimensional scaling based on the independent observer similarity ratings. A linear mixed-effects model demonstrated that both visual and semantic similarity influenced the probability that distractors would be fixated. However, the visual similarity effect was substantially larger than the semantic similarity effect. We close by discussing the potential value of using this novel methodological approach and the implications for both simple and complex visual search displays.
