“…Impulsivity as assessed with the BIS-11 can be further subdivided into attentional, motor, and non-planning impulsivity, but most clinical studies employ the sum score. Compatible with the clinical observation of frequent impulsive behavior in BPD, higher BIS-11 scores have frequently been observed in BPD patients compared to healthy controls ( Henry et al, 2001 , Berlin et al, 2005 , McCloskey et al, 2009 , Jacob et al, 2010 , Lynam et al, 2011 , Sebastian et al, 2013 ) and also to other patient groups like patients with bipolar II disorder ( Henry et al, 2001 , Wilson et al, 2007 , Boen et al, 2015 ) or even patients with orbitofrontal cortex lesions ( Berlin et al, 2005 ). Several studies of impulsivity in BPD using laboratory tasks have provided direct evidence for behavioral manifestations of impulsivity, such as impaired response inhibition ( Leyton et al, 2001 , Hochhausen et al, 2002 , Rentrop et al, 2008 ), difficulties in feedback-guided decision making ( Haaland and Landro, 2007 , Maurex et al, 2009 , Svaldi et al, 2012 , Mak and Lam, 2013 ), and higher levels of impulsive aggression ( Dougherty et al, 1999 , New et al, 2009 ) in BPD patients compared to clinical and nonclinical controls.…”
