Flat affect was examined across multiple contexts (during interviews and emotional films), multiple channels of expression (facial and vocal), and different assessment techniques (clinical ratings, observational ratings of facial expression, and acoustic analyses) in 23 medication-free schizophrenic patients. Patients participated in three different interviews during which either clinical ratings were made or their voices were audiotaped for later acoustic analyses. Patients were also videotaped while they viewed positive and negative emotional films. The videotapes were then coded for the frequency, intensity, and duration of positive and negative facial expressions. Results indicated that general clinical ratings were related across different interviews. However, only those items specific to affective flattening bore significant relationships to vocal and facial expressiveness. Vocal expressiveness and negative facial expressiveness were related, but vocal expressiveness was not related to positive facial expressiveness.
在23名未服用药物的精神分裂症患者中，通过多种情境（访谈期间和观看情感电影时）、多种表达渠道（面部和声音）以及不同评估技术（临床评分、面部表情观察评分和声学分析）对情感平淡进行了研究。患者参与了三次不同的访谈，期间进行临床评分或对其声音进行录音以便后续进行声学分析。患者在观看正面和负面情感电影时也被录像。然后对录像带中正面和负面面部表情的频率、强度和持续时间进行编码。结果表明，不同访谈中的总体临床评分具有相关性。然而，只有那些特定于情感平淡的项目与声音和面部表现力存在显著关系。声音表现力与负面面部表现力相关，但声音表现力与正面面部表现力无关。
