Increasing evidence shows that sensitivity to reward (SR) and punishment (SP) may be involved in eating disorders (EDs). Most studies used self-reported positive/negative effect in rewarding/punishing situations, whereas the implied proneness to detect signals of reward/punishment is largely ignored. This pilot study used a spatial orientation task to examine transdiagnostic and interdiagnostic differences in SR/SP. Participants (14–29 years) were patients with anorexia nervosa of restricting type (AN-R, n = 20), binge/purge ED group [AN of binge/purge ty pe and bulimia nervosa (n = 16)] and non-symptomatic individua ls (n = 23). Results revealed stronger difﬁculties to redirect attention away from signals of rewards in AN-R compared with binge/purge EDs, and inge/purge EDs showed stronger difﬁculties to direct attention away from signals of punishment compared with AN-R. Findings demonstrate inter diagnostic differences and show that the spatial orientation task is sensitive for individual differences in SP/SR within the context of EDs, thereby sustaining its usefulness as behavioural measure of reinforcement sensitivity.
