快乐的脸包括嘴部（微笑）和眼睛区域（例如眼睛）的外观变化。例如，在一个实施例中，眼睛张开变窄）。本实验研究是否实现的基础上的微笑单独或是否在眼睛区域的信息也被使用的幸福的面孔的识别。一个去/不去的任务中，参与者回应快乐的面孔，并保留一个不快乐的分心的反应。眼睛中的表达线索的存在/不存在并不影响识别的准确性，但反应时间稍长的微笑没有表达线索的眼睛。当面部的上半部分和下半部分不对齐时，或者当干扰物从顶部主导的面部表情改变为底部主导的面部表情时（即，从愤怒到厌恶）。总之，这些结果表明，眼睛可能有一个温和的影响，快速识别快乐的面孔，虽然这种效果的存在可能取决于任务的上下文。
Happy faces involve appearance changes in the mouth (the smile) and eye region (e. g., narrowing of the eye opening). The present experiments investigated whether the recognition of happy faces is achieved on the basis of the smile alone or whether information in the eye region is also used. A go/no-go task was used in which participants responded to happy faces and withhold a response to nonhappy distractors. The presence/absence of the expressive cues in the eyes did not affect recognition accuracy but reaction times were slightly longer for smiles without expressive cues in the eyes. This delay was not obtained when the top and the bottom halves of the faces were misaligned, or when the distractor was changed from a top-dominant to a bottom-dominant facial expression (i.e., from anger to disgust). Together, these results suggest that the eyes may have a modest effect on speeded recognition of happy faces although the presence of this effect may depend on task context.
