先前的研究发现，年轻人比其他类型的刺激更快地发现威胁性刺激。这项研究调查了老年人是否也表现出这种适应性威胁检测优势。在实验的每一次试验中，参与者都看到了一组由九张示意图组成的面孔。其中8张脸是中性的；第九个是中性的、生气的、快乐的或悲伤的。参与者指出在每个数组中是否有不一致的脸。无论是老年人还是年轻人，在识别威胁表情时都比识别快乐或悲伤表情时要快得多。这种威胁检测优势没有年龄差异，表明这种自动过程在老年人中保持不变。
Previous studies have found that younger adults detect threatening stimuli more quickly than other types of stimuli. This study examined whether older adults also show this adaptive threat-detection advantage. On each trial in the experiment, participants saw an array consisting of nine schematic faces. Eight of the faces were neutral; the ninth was neutral, angry, happy, or sad. Participants indicated whether there was a discrepant face in each array. Both older and younger adults were significantly faster to correctly detect a discrepant face when it signaled threat than when it signaled happiness or sadness. There was no age difference in this threat-detection advantage, indicating that this automatic process is maintained among older adults.
