Background/Study Context: The face is the most distinctive physical feature of a person. Previous work has shown that one's own face (self-face) is advantageous in perception. Here the authors investigate how aging influences the configural and featural processing of self-face.
Older and young adults searched for their own faces and faces of strangers (Experiment 1) or acquaintances (Experiment 2) among distractor faces. The configural and featural processing of faces was assessed with face inversion in Experiment 1 and with changes in point of view in Experiment 2.
Experiment 1 revealed a robust self-face advantage for upright faces in both young and older adults. A similar advantage was observed for inverted faces in young but not in older adults. Experiment 2 revealed a self-face advantage in older adults regardless of the point of view; in young adults, however, the self-face advantage only emerged for frontal view faces.
The present study shows that older adults have a self-face advantage in configural but not in featural processing. The authors suggest that the impairment in featural processing in older adults is likely the result of age-related changes in perceptual experience.
背景/研究背景:面部是一个人最具辨识度的身体特征。先前的研究表明,自己的面部(自我面部)在感知方面具有优势。在此,作者研究衰老如何影响自我面部的整体和局部特征加工。
老年人和年轻人在干扰面孔中寻找自己的面孔以及陌生人(实验1)或熟人(实验2)的面孔。在实验1中,通过面部倒置评估面孔的整体和局部特征加工;在实验2中,通过视角变化进行评估。
实验1显示,年轻人和老年人在直立面孔上均表现出显著的自我面部优势。在年轻人中,倒置面孔也观察到类似优势,但老年人中未观察到。实验2显示,无论视角如何,老年人都存在自我面部优势;然而,在年轻人中,自我面部优势仅在正视图面孔中出现。
本研究表明,老年人在整体特征加工而非局部特征加工方面具有自我面部优势。作者认为,老年人局部特征加工受损可能是感知经验中与年龄相关变化的结果。
