Patients with AN (n = 29), healthy controls comparable in age and IQ (HC. n = 29), and women long term recovered from AN (n = 14), completed the Iowa Gambling Task (IGT) while their SCR were measured. AN patients performed poorly in the IGT compared to the HC and to the recovered AN participants. AN patients had decreased anticipatory SCR prior to choosing cards and reduced SCR after losses compared to HC. IGT performance and the SCR of recovered AN participants did not differ froth the HC. Decision making ability is impaired in AN. It is associated with a significantly attenuated SCR. Neither of these features are found in recovered AN. The association between impaired decision making ability and a decreased autonomic response is consistent with the predictions of the Somatic Marker Hypothesis",
