我们研究了早期视觉剥夺对六种基本情绪的潜在表征的影响。使用多维尺度（MDS），我们比较了成人谁错过了早期的视觉输入，因为双侧先天性白内障，以控制视力正常的成年人的相似性判断。参与者在三种不同的强度下对六种基本情绪表达进行了相似性判断，加上中性。与以往的研究一致，典型成年人的相似性判断可以用四个基本维度来建模，这四个维度可以被解释为代表愉悦、唤醒、效能和表达强度。作为一个群体，白内障逆转患者表现出一个系统的结构，其维度代表快乐，潜力和强度。然而，在患者组的判断中，觉醒维度并不明显。分层聚类分析显示，在典型的7岁儿童中观察到的患者模式，而不是典型的14岁儿童或成人。与对照组相比，患者之间的变异性也更大，这一点可以通过MDS与患者数据拟合的更高应力值和四个维度上更分散的权重来证明。研究结果表明，早期的视觉经验在塑造后来的发展中的代表性的情绪的重要作用。由于情绪的正常基础结构在出生后出现，并持续完善，直到童年晚期，成年患者的情绪表征改变表明睡眠效应。
We investigated the effects of early visual deprivation on the underlying representation of the six basic emotions. Using multi-dimensional scaling (MDS), we compared the similarity judgments of adults who had missed early visual input because of bilateral congenital cataracts to control adults with normal vision. Participants made similarity judgments of the six basic emotional expressions, plus neutral, at three different intensities. Consistent with previous studies, the similarity judgments of typical adults could be modeled with four underlying dimensions, which can be interpreted as representing pleasure, arousal, potency and intensity of expressions. As a group, cataract-reversal patients showed a systematic structure with dimensions representing pleasure, potency, and intensity. However, an arousal dimension was not obvious in the patient group's judgments. Hierarchical clustering analysis revealed a pattern in patients seen in typical 7-year-olds but not typical 14-year-olds or adults. There was also more variability among the patients than among the controls, as evidenced by higher stress values for the MDS fit to the patients' data and more dispersed weightings on the four dimensions. The findings suggest an important role for early visual experience in shaping the later development of the representations of emotions. Since the normal underlying structure for emotion emerges postnatally and continues to be refined until late childhood, the altered representation of emotion in adult patients suggests a sleeper effect.
