采用视觉搜索范式，研究了年龄对情绪面部表情注意偏向的影响。在实验I和2中，参与者在一个矩阵中寻找一个不一致的面部表情，否则均匀的面孔。年轻人和老年人都表现出更有效的搜索时，不一致的脸是愤怒，而不是快乐或中立。然而，当愤怒的面孔作为非目标干扰物时，年轻人的搜索不如快乐或中性干扰物条件有效。相比之下，老年人对愤怒的干扰物的搜索效率高于快乐或中性的干扰物，这表明老年人能够更好地抑制愤怒的面部表情。在实验3中，我们发现，即使是一个自上而下的搜索目标不能推翻愤怒的脸优势效应在引导注意力。此外，RT分布分析支持年轻人和老年人进行自上而下的愤怒的脸搜索从质量上不同的自上而下的快乐的脸搜索。目前的研究表明，威胁面孔加工包括自动注意转移和控制注意过程。目前的研究结果表明，年龄只影响控制注意过程。(c)2006 Eelsevier B.V.保留所有权利。
Using a visual search paradigm, we investigated how age affected attentional bias to emotional facial expressions. In Experiments I and 2, participants searched for a discrepant facial expression in a matrix of otherwise homogeneous faces. Both younger and older adults showed a more effective search when the discrepant face was angry rather than happy or neutral. However, when the angry faces served as non-target distractors, younger adults' search was less effective than happy or neutral distractor conditions. In contrast, older adults showed a more efficient search with angry distractors than happy or neutral distractors, indicating that older adults were better able to inhibit angry facial expressions. In Experiment 3, we found that even a top-down search goal could not override the angry face superiority effect in guiding attention. In addition, RT distribution analyses supported that both younger and older adults performed the top-down angry face search qualitatively differently from the top-down happy face search. The current research indicates that threat face processing involves automatic attentional shift and a controlled attentional process. The current results suggest that age only influenced the controlled attentional process. (c) 2006 Eelsevier B.V. All rights reserved.
