Older adults have a specific deficit in their ability to identify some negative facial emotions. The present study investigated the influence of intensity of expression on 40 young and 40 older adults' recognition of facial expressions of emotion. Older adults showed no impairment in the perception of low-intensity subtle expressions of happiness, surprise, and disgust. However, older adults were worse at recognizing all intensities of sadness, anger, and fear, with the greatest impairment at 50% intensity. Observed age differences were not influenced by covarying general facial processing skills, but were substantially reduced when a measure of general cognitive functioning was covaried. The current study suggests that age differences in identifying facial expressions of emotion are not caused by decreasing visual perceptual abilities, but may partially overlap with general cognitive changes.
老年人在识别某些负面面部情绪的能力上存在特定缺陷。本研究调查了表情强度对40名年轻人和40名老年人面部表情识别的影响。老年人在感知低强度的幸福、惊讶和厌恶的微妙表情方面没有受损。然而,老年人在识别悲伤、愤怒和恐惧的所有强度表情时表现较差,在50%强度时受损最大。观察到的年龄差异不受一般面部处理技能变化的影响,但在将一般认知功能的测量值作为协变量时,差异大幅减小。当前研究表明,识别面部表情的年龄差异不是由视觉感知能力下降引起的,而是可能与一般认知变化部分重叠。
