Behavioral measures that may be useful intermediate phenotypes between “personality” and neurological functioning should also be considered. Miyake et al. (2000) factor analyzed behavioral measures of executive functioning and identified specific subtypes of this construct, including facets related to impulsivity (also see Dougherty, Mathias, Marsh, & Jaspar, 2005). More specifically, Dick et al. (2010) recently noted that laboratory tasks thought to measure prepotent response inhibition (i.e., the ability to suppress automatic thoughts) such as go/no-go tasks (Marczinski & Fillmore, 2003) may relate to urgency facets of the UPPS-P impulsivity scale (Cyders et al., 2007; Lynam, Smith, Whiteside, & Cyders, 2006). Further, the lack of perseverance facet of the UPPS-P may relate to laboratory tasks such as word naming tasks (Kane, Hasher, Stoltzfus, Zacks, & Connelly, 1994) thought to measure the resistance to distractor interference (i.e., avoiding interference from task-irrelevant information; Friedman & Miyake, 2004). Lack of perseverance may also relate to tasks measuring resistance to proactive interference (i.e., resisting memory invasive information that was previously relevant to the current task; Friedman & Miyake, 2004) such as cued recall tasks (Tolan
