在 23 名未接受药物治疗的精神分裂症患者中，研究人员在多种情境（采访和情感电影期间）、多种表达渠道（面部和声音）和不同的评估技术（临床评级、面部表情观察评级和声学分析）中检查了扁平情感。患者参加了三个不同的访谈，期间要么进行临床评级，要么对他们的声音进行录音以供以后的声学分析。患者观看积极和消极情绪电影时也会被录像。然后对录像带进行编码，记录积极和消极面部表情的频率、强度和持续时间。结果表明，不同访谈中的一般临床评分相关。然而，只有那些特定于情感扁平化的项目与声音和面部表情有显着关系。声音表现力与消极面部表情相关，但声音表现力与积极面部表情无关。
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.
