ABSTRACT

We examined the interaction among emotions, spatial frequencies (SF) and holistic analysis using an anorthoscopic paradigm, which is supposed to alter the holistic processing. Emotional and neutral faces were presented sliding behind a narrow aperture (anorthoscopy), or statically in the centre of the screen (whole-face presentation) as broadband images (Experiment 1), filtered at low-SF (Experiment 2), and “hybrids” (emotional low-SF superimposed to neutral high-SF of the same face; Experiment 3). Participants were required to evaluate how “friendly” each stimulus appeared (an indirect measure of emotion processing). These manipulations were aimed at investigating holistic accounts of emotional faces. Friendliness judgments decreased when low-SF and hybrid faces were presented anorthoscopically, possibly due to the impoverished presentation, in which a part-based analysis prevails on a global-based analysis. Although anorthoscopy does not prevent emotion processing, it alters holistic processing of emotional stimuli, confirming the complex interaction among emotions, SF and stimulus presentation.

摘要

我们使用正畸镜范式检查了情绪、空间频率 (SF) 和整体分析之间的相互作用，这应该会改变整体处理。情绪化和中性的面孔在狭窄的光圈后面滑动（鼻镜检查），或静态地在屏幕中央（全脸展示）作为宽带图像（实验 1），在低 SF 过滤（实验 2）和“混合”（情感低 SF 叠加到同一张脸的中性高 SF；实验 3）。参与者被要求评估每个刺激出现的“友好”程度（情绪处理的间接测量）。这些操作旨在调查情绪面孔的整体描述。当低 SF 和混合面部在鼻镜下呈现时，友好度判断降低，可能是由于呈现不佳，其中基于部分的分析优于基于全局的分析。虽然鼻腔镜检查不能阻止情绪处理，但它改变了情绪刺激的整体处理，证实了情绪、SF 和刺激呈现之间的复杂相互作用。
