“…Some labbased experimental studies of EFs suggest that lab-induced affect, such as anxiety or pleasant mood, can lead to changes in EF performance, suggesting that such variation reflects fluctuations in EFs during a short period of time (Katzir et al, 2010;Lindström & Bohlin, 2012;Oaksford et al, 1996;Phillips et al, 2002). Studies using repeated assessments have also documented meaningful within-person fluctuations in EF in naturalistic settings (Brose et al, 2010(Brose et al, , 2012(Brose et al, , 2015Gamaldo et al, 2010;Könen et al, 2015;Kramer et al, 2020;Neubauer et al, 2019;Schmiedek et al, 2009;Yu et al, 2020Yu et al, , 2021. Identifying factors in the context or the person that coact with fluctuations in EF can provide information for optimization EF on a daily basis.…”
