“…A total of 37 studies explored the process of insight problem solving using RAT, including how individuals' memory (e.g., false memory) affects their developing insight (Howe et al, 2010(Howe et al, , 2011(Howe et al, , 2016Garner and Howe, 2014;Kizilirmak et al, 2016b;Ellis and Brewer, 2018;Howe and Garner, 2018), the incubation mechanism, such as dreams (Sio and Rudowicz, 2007;Vul and Pashler, 2007;Cai et al, 2009;Kohn and Smith, 2009;Penaloza and Calvillo, 2012;Nam and Lee, 2015;Sio and Ormerod, 2015;Morrison et al, 2017;Sio et al, 2017), how representational change affects one's insight problem solving (Barton et al, 2009), the aha! experience of insight (Bowden and Jung-Beeman, 2003b;Du et al, 2017;Kraus and Holtgraves, 2018), the mechanisms that occur in the brain when solving insight problems, such as brain networks, brain structure, brain function, and brain waves (Sandkühler and Bhattacharya, 2008;Kizilirmak et al, 2016a;Shen et al, 2016b;Rothmaler et al, 2017;Erickson et al, 2018;Ji et al, 2018;Ogawa et al, 2018;Ruggiero et al, 2018;Tik et al, 2018;Tempest and Radel, 2019), and eye movements (Huang, 2017;Huang et al, 2019). In addition, some studies focused on how individuals' attention (Cushen and Wiley, 2018;Zmigrod et al, 2019), meta-cognition (Storm and Hickman, 2015), creative thinking fluency…”
