在这项研究中，我们考察了双相情感障碍缓解期患者的情感匹配能力是否存在损害，这是否可以归因于面部感知本身和/或感知面部表情指示情绪的相对有效性的能力。我们检查了19名目前缓解的双相情感障碍患者和30名健康对照组(15名男性)，他们在年龄、教育程度和性别上匹配，使用两种计算机化测试：匹配面部认同感[Kinney的身份匹配测试(KIMT)]和匹配面部情感表达[Kinney的情感匹配测试(KAMT)]。双相情感障碍患者在KAMT上的表现明显低于健康组，但不是在KIMT上。在KAMT和KIMT上的表现与发病年龄和病程无关，也与躁狂或抑郁的残留症状无关。本研究结果支持差异缺陷假说，即双相情感知觉在缓解期受损。患者的缺陷仅限于面部表情的匹配，尽管他们对面部身份的感知完好无损。(C)2005 Elsevier B.V.保留所有权利。
In the present study, we examined whether there is an impairment in affect matching abilities in remitted patients with bipolar disorder and if this Could be attributed to problems with facial perception per se and/or the ability to perceive the relative valence of facial expressions indicating emotions.We examined 19 patients with bipolar disorder 1, currently remitted, and 30 healthy controls (15 men), matched on age, education, and gender, using two computerized tests: matching facial identity [Kinney's Identity Matching Test (KIMT)] and matching facial emotional expressions [Kinney's Affect Matching Test (KAMT)].Patients with bipolar disorder performed significantly worse than the healthy group on the KAMT, but not on the KIMT. Performance on the KAMT and KIMT did not correlate with age of onset and duration of illness, or with manic or depressive residual symptoms.The present findings support the differential deficit hypothesis regarding impaired affect perception in bipolar disorder during remission. Patients' deficits were restricted to the matching of facial emotional expressions despite their intact perception of facial identity. (c) 2005 Elsevier B.V. All rights reserved.
