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 type and bulimia nervosa (n = 16)] and non‐symptomatic individuals (n = 23). Results revealed stronger difficulties to redirect attention away from signals of rewards in AN‐R compared with binge/purge EDs, and binge/purge EDs showed stronger difficulties to direct attention away from signals of punishment compared with AN‐R. Findings demonstrate interdiagnostic 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.
