“…Deliberate mental imagery generation plays a key role in action planning (Keller, 2012), simulating past and future events (D'Argembeau & Van der Linden, 2006), and escapism (Schäfer, Sedlmeier, Städtler, & Huron, 2013). Such mental imagery is also a feature of evidence-based psychotherapeutic treatment for mood and anxiety disorders (Hackmann, Bennett-Levy, & Holmes, 2011;Hirsch & Holmes, 2007;Pearson, Naselaris, Holmes, & Kosslyn, 2015;Blackwell, 2019;Holmes, Arntz, & Smucker, 2007;Lang, 1977;McEvoy, Saulsman, & Rapee, 2018;Mendes, Mello, Ventura, De Medeiros Passarela, & De Jesus Mari, 2008;Pile, Williamson, Saunders, Holmes, & Lau, 2021;Saulsman, Ji, & McEvoy, 2019). A key concern is that whilst these therapies are remarkably effective (Arntz, 2012), their efficacy may be affected by patients' ability to alter vividness and content of mental imagery (Johnsen & Lutgendorf, 2001;Mota et al, 2015;Richardson & Taylor, 1982;Stopa, 2011).…”
