我们使用视觉搜索，以探讨是否前注意机制，使快速检测面部表情是由视觉信息驱动的表情中的功能位移，或其他因素，如影响。我们测量了搜索斜率的亮度和对比度相等的图像的面部表情和反表情的六种情绪（愤怒，恐惧，厌恶，惊讶，幸福和悲伤）。反表情与相应表情的面部特征位移量相当，但情感内容不同。这些搜索斜率与表达式和反表达式中特征位移的大小之间存在很强的相关性，表明特征位移对搜索性能有影响。对快乐、悲伤、愤怒和惊讶的表情和反表情的搜索斜率存在显著差异，这不能用特征差异来解释，表明前注意机制对其他因素敏感。分类任务证实，情感内容的表达和反表达的每一个这些情绪是不同的，这表明信号的影响可能会影响注意力和搜索性能。我们的研究结果支持这样一种观点，即前注意机制可能是由多个层面的因素驱动的，包括影响和特征位移的大小。我们注意到，特征位移的间接影响，如局部对比度的变化，可能会影响前注意处理。这些最有可能是非线性相关的功能位移，我们认为，任何研究使用图像的表达，探索如何影响引导注意力的一个重要考虑因素。我们还注意到，特征位移的间接影响（例如，局部对比度的变化）可能会影响前注意处理。我们认为，这种影响是一个重要的考虑任何研究使用的图像的表达，以探讨如何影响引导注意力。
We used visual search to explore whether the preattentive mechanisms that enable rapid detection of facial expressions are driven by visual information from the displacement of features in expressions, or other factors such as affect. We measured search slopes for luminance and contrast equated images of facial expressions and anti-expressions of six emotions (anger, fear, disgust, surprise, happiness, and sadness). Anti-expressions have an equivalent magnitude of facial feature displacements to their corresponding expressions, but different affective content. There was a strong correlation between these search slopes and the magnitude of feature displacements in expressions and anti-expressions, indicating feature displacement had an effect on search performance. There were significant differences between search slopes for expressions and anti-expressions of happiness, sadness, anger, and surprise, which could not be explained in terms of feature differences, suggesting preattentive mechanisms were sensitive to other factors. A categorization task confirmed that the affective content of expressions and anti-expressions of each of these emotions were different, suggesting signals of affect might well have been influencing attention and search performance. Our results support a picture in which preattentive mechanisms may be driven by factors at a number of levels, including affect and the magnitude of feature displacement. We note that indirect effects of feature displacement, such as changes in local contrast, may well affect preattentive processing. These are most likely to be nonlinearly related to feature displacement and are, we argue, an important consideration for any study using images of expression to explore how affect guides attention. We also note that indirect effects of feature displacement (for example, changes in local contrast) may well affect preattentive processing. We argue that such effects are an important consideration for any study using images of expression to explore how affect guides attention.
