Women with eating disorders (EDs) are reported to have strengths in local or detailed information processing and difficulties with coherence or global processing/integration.
This study aimed to replicate these findings and additionally explore a global integration task which has not previously been reported for an ED group, the Fragmented Pictures Task (FPT). Two hundred and twenty-two women (50 with anorexia nervosa (AN), 48 with bulimia nervosa (BN), 35 recovered from AN and 89 controls (HC)) completed the Rey-Osterrieth Complex Figure Task (RCFT) to measure global/local processing strategies, the Group Embedded Figures Task (GEFT) to measure local processing and the FPT to measure global integration.
Superior detail processing skills (GEFT) and a tendency to utilise detail processing strategies (RCFT) were associated with having AN, BN and being in recovery from AN. Global integration difficulties (FPT) were only observed in acute AN, whereas participants in the BN and recovered group performed similarly to HCs.
People currently ill with, and recovered from EDs are skilled at detail processing. The acute phase of AN is associated with difficulties in global integration.
据报道，患有饮食失调症（ED）的女性在局部或详细信息处理方面具有优势，而在连贯性或全局处理/整合方面存在困难。
本研究旨在复制这些发现，并进一步探讨以前未在 ED 组中报告过的全局整合任务，即碎片化图片任务（FPT）。222 名女性（50 名神经性厌食症（AN）患者，48 名神经性贪食症（BN）患者，35 名 AN 恢复期患者和 89 名对照组（HC））完成了 Rey-Osterrieth 复杂图形任务（RCFT）以测量全局/局部处理策略，团体嵌入图形任务（GEFT）测量局部处理，以及碎片化图片任务（FPT）测量全局整合。
详细处理技能（GEFT）和使用详细处理策略的倾向（RCFT）与 AN、BN 和从 AN 中恢复有关。仅在急性 AN 中观察到全局整合困难（FPT），而 BN 和恢复期组的参与者与 HC 表现相似。
目前患有 ED 和已从 ED 中恢复的人在细节处理方面很熟练。AN 的急性阶段与全局整合困难有关。
