Research has shown that the ability to label negative emotions displayed by facial expressions declines with age. Such studies, however, have tended to adopt the Ekman and Friesen (1976) Caucasian faces as their emotional stimuli. The purpose of the current study was to examine whether the age differences in identifying negative emotions are also found using the more recent Japanese and Caucasian Facial Expressions of Emotion (JACFEE).
In Experiment 1, 29 younger and 29 older individuals performed a verbal labeling emotion identification task (happy, sad, angry, frightened, disgusted, surprised, contemptuous). The ability to identify each emotion as a function of ethnicity across the age groups was examined. In order to reduce the verbal decision-making load on the task, a second experiment was conducted in which 60 younger and 60 older participants performed an emotion-matching task (sad, angry, contemptuous).
In Experiment 1, older adults showed a significant decrement in the ability to recognize sad faces compared with younger adults, but no age x face ethnicity interaction was found. In Experiment 2, age differences were found when making same/different judgments regarding two sad faces or a sad and a contemptuous face.
Results suggest that aging has an impact upon perceiving sad facial expressions, that this effect is not mediated by own-race versus other-race faces, and that age effects are not attributable to differences in verbal decision-making.
研究表明,识别面部表情所展现的负面情绪的能力会随着年龄增长而下降。然而,此类研究往往采用埃克曼和弗里森(1976)的高加索人面部表情作为情绪刺激物。本研究的目的是探讨使用更新的日本和高加索人面部表情(JACFEE)时,在识别负面情绪方面是否也存在年龄差异。
在实验1中,29名年轻人和29名年长者进行了一项言语标签情绪识别任务(高兴、悲伤、愤怒、恐惧、厌恶、惊讶、轻蔑)。研究了各年龄组将每种情绪识别为种族函数的能力。为了减轻任务中的言语决策负担,进行了第二个实验,60名年轻参与者和60名年长参与者进行了情绪匹配任务(悲伤、愤怒、轻蔑)。
在实验1中,与年轻人相比,年长者识别悲伤面孔的能力显著下降,但未发现年龄×面孔种族的交互作用。在实验2中,在对两张悲伤面孔或一张悲伤面孔和一张轻蔑面孔进行相同/不同判断时发现了年龄差异。
结果表明,衰老对面部悲伤表情的感知有影响,这种影响不受本种族与其他种族面孔的介导,且年龄效应并非归因于言语决策的差异。
