“…Cognitive fatigue can be defined as arising from the 'prolonged performance of cognitively demanding tasks requiring sustained mental efficiency' (Lorist, 2008). This acute state of induced cognitive fatigue is associated with increased subjective fatigue, behavioral performance decrements and decreased amplitude of event-related potential components (Boksem, Meijman, & Lorist, 2006;Kato, Endo, & Kizuka, 2009;Lorist, 2008;Lorist, Boksem, & Ridderinkhof, 2005;van der Linden, Frese, & Meijman, 2003). Cognitively demanding tasks have also been shown to elicit a cortisol stress response in some individuals (Bohnen, Houx, Nicolson, & Jolles, 1990;Kukolja, Thiel, Wolf, & Fink, 2008).…”
