Final answer:
Impulsivity, risk-taking, and thrill-seeking behavior is the characteristic commonly associated with both Psychopathic Deviate and Hypomania.
Step-by-step explanation:
The personality and interpersonal characteristic commonly associated with both Psychopathic Deviate and Hypomania is impulsivity, risk-taking, and thrill-seeking behavior. These traits align with the theoretical frameworks surrounding psychopathy and hypomanic episodes. Individuals who display these characteristics may engage in behaviors without considering the potential consequences, seeking excitement and stimulation often without regard for their own safety or the wellbeing of others. This corresponds with the tendency towards antisocial behaviors and lack of empathy typically observed in psychopathic individuals and the increased energy and activity levels seen in hypomania.
