“…Attention wanders on and off a given task, fluctuating even in the absence of salient external distractors (Esterman, Noonan, Rosenberg, & Degutis, 2013). Previous work with adults has demonstrated that greater fluctuations in attention predicted impairments in task performance (Bellgrove, Hester, & Garavan, 2004; Haynes, Bauermeister, & Bunce, 2016; Unsworth & McMillan, 2014). Importantly, individuals who were more susceptible to attentional fluctuations showed poorer performance not only during the task in which fluctuations were measured, but also in other fundamental cognitive functions including working memory, prospective memory, and fluid intelligence (Ihle, Ghisletta, & Kliegel, 2016; Kane et al, 2016; Larson & Saccuzzo, 1989; Unsworth, 2015).…”
