“…Performance on tests of executive function or self-control decline with exposure to stress (Pabst, Schoofs, Pawlikowski, Brand, & Wolf, 2013; Tryon, Carter, Decant, & Laugero, 2013), increased cognitive demands (Gathmann, Pawlikowski, Scholer, & Brand, 2014; Gunn & Finn, 2015; Hinson, Jameson, & Whitney, 2003; Starcke, Pawlikowski, Wolf, Altstotter-Gleich, & Brand, 2011), and insufficient sleep (Reynolds & Schiffbauer, 2004; Rossa, Smith, Allan, & Sullivan, 2014; Whitney & Hinson, 2010). Even more troubling are studies suggesting that executive functions often fail when they are needed most, such as during “hot” states characterized by visceral arousal (Ariely & Loewenstein, 2006; Loewenstein, 1996; Metcalfe & Mischel, 1999) or with mere exposure to a tempting stimulus (Hagger et al, 2013; Heatherton & Wagner, 2011).…”
