“…Working memory capacity has been defined as the ability to maintain information (including goals) in working memory and to shield that information from interference from competing stimuli. Although some research has suggested that Barratt Impulsivity scores (BIS-11; (Patton et al, 1995) are related to lower working memory capacity (Berlin et al, 2005), most authors have observed null effects of this scale with working memory tasks, including the digit span task (Day et al, 2013;Lopez-Vergara et al, 2019), the N-back task (Mueller et al, 2017;Whitney et al, 2004;Zeng et al, 2013), the CANTAB test of spatial working memory (Berlin et al, 2005;Manning et al, 2013), the O-Span task (Lempert & Pizzagalli, 2010), or a composite of well-validated working memory tasks (Visser et al, 2019). In parallel, findings have been mixed on whether working memory training lowers BIS-11 scores (Brooks et al, 2017;Wanmaker et al, 2017).…”
