Recognition of others’ interoceptive states in those with and without eating disorders

Abstract Background The ability to recognize one’s own emotions is associated with one’s ability to recognize others’ emotions. Beyond the domain of emotion, however, the relationship between recognition of one’s own internal states (interoception) and others’ interoceptive states has not been investigated, either in the typical population or clinical groups with interoceptive difficulties (e.g. eating disorders; EDs). Method This study investigated recognition of one’s own and others’ internal states in adults with and without eating disorders, using a high frequency visual noise paradigm. Participants completed self-report measures of interoception, alexithymia (difficulties recognising one’s own emotional internal states) and ED symptomatology, and the Heartbeat Counting Task measure of cardiac interoceptive accuracy. Results Alexithymia was significantly negatively correlated with recognition of others’ interoceptive states. EDs were not associated with difficulties recognising others’ interoceptive states. Conclusions The ability to recognise one’s own emotional internal states is associated with the recognition of others’ interoceptive states, which may contribute to social skills and the ability to care for others.
