精神分裂症的特点是情绪和语言异常。然而，尽管有报道保留了对情感刺激效价的评估，例如图片，但尚不清楚精神分裂症患者如何评估具有情感效价的言语材料，例如，相对于单词的愉快/吸引力的整体不愉快/不愉快。这项研究旨在调查与一组健康对照者相比，精神分裂症患者如何评价形容词的情感效价。提出了一百八十四个不同价态的形容词。这些形容词之前被五名未参与当前实验的评委分类为“中性”、“积极”（令人愉快）或“消极”（不愉快）。这三个类别的形容词在词长、频率和熟悉度上进行了匹配。 16 名患有精神分裂症的个体和 17 名健康对照者被要求使用计算机化版本的自我评估模型（Bradley 和 Lang，1994）对每个单词的效价进行评分。结果表明，词语情感效价的评级相似，这表明精神分裂症患者的情感知识具有相似的表征，至少在效价维度方面如此。
Schizophrenia is characterized by both emotional and language abnormalities. However, in spite of reports of preserved evaluation of valence of affective stimuli, such as pictures, it is less clear how individuals with schizophrenia assess verbal material with emotional valence, for example, the overall unpleasantness/displeasure relative to pleasantness/attraction of a word. This study aimed to investigate how schizophrenic individuals rate the emotional valence of adjectives, when compared with a group of healthy controls. One hundred and eighty-four adjectives differing in valence were presented. These adjectives were previously categorized as “neutral,” “positive” (pleasant), or “negative” (unpleasant) by five judges not participating in the current experiment. Adjectives from the three categories were matched on word length, frequency, and familiarity. Sixteen individuals with schizophrenia diagnosis and seventeen healthy controls were asked to rate the valence of each word, by using a computerized version of the Self-Assessment Manikin (Bradley and Lang, 1994). Results demonstrated similar ratings of emotional valence of words, suggesting a similar representation of affective knowledge in schizophrenia, at least in terms of the valence dimension.
