inter-correlation among the five traits (which are described below) was 0.25 in a recent study (Cyders & Smith 2007; Cyders et al. 2007). Two of the five dispositions are emotion-based: positive urgency is the tendency to act rashly when experiencing extremely positive mood, and negative urgency is the tendency to act rashly when experiencing extremely negative mood. Two are based on deficits in conscientiousness: lack of planning is the tendency to act without forethought, and lack of perseverance reflects a failure to tolerate boredom or to remain focused despite distraction. The fifth is sensation seeking, or the tendency to seek out novel or thrilling stimulation (Zuckerman 1994; Whiteside & Lynam 2001, 2003; Whiteside et al. 2005; Cyders & Smith 2007; Smith et al. 2007).
