To examine the concept of central coherence in women with bulimia nervosa (BN) and address similarities and difference with those with anorexia nervosa (AN) METHOD: Forty two women with BN and 42 matched healthy women, completed neuropsychological testing measuring aspects of central coherence: Rey-Osterrieth Complex Figure (RCFT), Embedded Figures Test (EFT), Block Design Test (BD), Homograph Reading Test (HRT), and Sentence Completion Task (SCT).
The BN group showed superiority in local processing as measured by EFT and lesser relative advantage from segmentation in BD, and difficulties in global processing in both visual and verbal domains as examined by RCFT, HRT, and SCT. Anxiety levels were associated with low central coherence indices in RCFT.
People with BN displayed a profile consistent with the weak central coherence hypothesis. Their pattern of cognitive performance resembles that seen in AN although some differences are apparent.
研究神经性贪食症（BN）女性的中心连贯性概念，并探讨其与神经性厌食症（AN）女性的异同。方法：42名BN女性和42名匹配的健康女性完成了神经心理学测试，以测量中心连贯性的各个方面：雷-奥斯特里思复杂图形测试（RCFT）、镶嵌图形测试（EFT）、积木设计测试（BD）、同形异义词阅读测试（HRT）和句子完成任务（SCT）。
通过EFT测量，BN组在局部加工方面表现出优势，在BD中分割的相对优势较小，并且在RCFT、HRT和SCT所考察的视觉和语言领域的整体加工方面存在困难。焦虑水平与RCFT中低中心连贯性指数相关。
BN患者表现出与弱中心连贯性假设一致的特征。他们的认知表现模式与AN患者相似，尽管存在一些明显差异。
