Despite the fact that facial expressions of emotion have signal value, there is surprisingly little research examining how that signal can be detected under various conditions, because most judgment studies utilize full-face, frontal views. We remedy this by obtaining judgments of frontal and profile views of the same expressions displayed by the same expressors. We predicted that recognition accuracy when viewing faces in profile would be lower than when judging the same faces from the front. Contrarily, there were no differences in recognition accuracy as a function of view, suggesting that emotions are judged equally well regardless of from what angle they are viewed.
尽管情感的面部表情具有信号价值,但令人惊讶的是,很少有研究探讨在各种条件下如何检测到这种信号,因为大多数判断研究都使用全脸、正面视图。我们通过获取同一表达者展示的相同表情的正面和侧面视图的判断来弥补这一点。我们预测,当从侧面观察面部时,识别的准确性会低于从正面判断相同面部时的准确性。相反,识别准确性不受观察角度的影响,这表明无论从哪个角度观察,情绪的判断都是一样的。
