People with eating disorders (EDs) are reported to have set-shifting difficulties, strengths in local or detailed information processing and weak central coherence or global processing. This study aimed to explore the validity of a novel, brief, global, neurocognitive task which has not previously been utilised in an ED population, the Navon Figures Task (NFT). The NFT is substantially quicker to administer than traditional neurocognitive tasks. Twenty women with anorexia nervosa (AN) and 20 healthy control women completed the Rey-Osterrieth Complex Figures Task (RCFT) to measure global/local processing strategies and completed the Wisconsin Card Sorting Test (WCT) to measure of set-shifting ability. The NFT was used as a measure of both set-shifting ability and central coherence. Consistent with previous findings, women with AN showed a tendency towards poorer performance on the RCFT and WCT than healthy control women. …
