Borderline Personality Disorder - Instability in relationships, job, mood, and self-image, including uncontrolled flashes of anger, impulsive behavior, and self-mutilation.
Desire that leads to impulsive behavior is caused by so-called "visceral factors," like the anticipation of the pleasure of eating the doughnut.
The researchers used questionnaires and interviews to obtain data regarding the subject's drinking and impulsive behavior, so they could determine if there was a correlation between the two.
