Participants completed the Go\/No\u2010Go discrimination task (a well\u2010validated computerized measure of response disinhibition), as well as self\u2010report questionnaires of impulsivity, eating symptoms, and general psychopathology.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Compared with the other groups, the BNL+ group made more commission errors on the Go\/No\u2010Go under cues for punishment, indicating they were more disinhibited when faced with possible negative outcomes. Compared with the BNL\u2212 group, the BNL+ group was also more likely to differ from the NE group on self\u2010reported impulsivity.
