Task-switching inefficiencies in currently ill, but not remitted anorexia nervosa.

ABSTRACT:

Objective

Models of anorexia nervosa (AN) posit that set-shifting deficits may contribute to behavioral inflexibility and extreme dietary restriction. Findings from neurocognitive studies of set-shifting in AN have been somewhat mixed, perhaps due to the use of tasks that cannot distinguish shifting from other processes (i.e., learning). To more precisely characterize cognitive flexibility and selectively assess this process independent of rule learning and feedback sensitivity, we examined task-switching ability in AN.

Method

Women ill with AN, subthreshold AN or atypical AN (IAN; n = 40), women remitted from AN (RAN; n = 24), and age-matched healthy control women (n = 42) completed a computerized cued color-shape task-switching paradigm. Groups were compared on mix costs (
