“…Challenge and threat are—just like flow—hypothesized to result from a balance between the demands of a task, and the resources that the person has to deal with these demands. When there is a balance between the demands of the task and the skills of the person, a challenge motivational state arises, whereas when the demands of the task outweigh the person's resources a threat motivational state arises (Blascovich, 2008; Blascovich & Mendes, 2010; Blascovich & Tomaka, 1996; Manigault et al, 2020; Mendes & Park, 2014; Seery, 2011; Wormwood et al, 2019). Thus, the shared appraisal profile of flow as described by flow theory on the one hand and challenge as described by the BPS‐CT on the other, makes the challenge pattern a likely candidate to represent a relevant physiological dimension of flow (see also Scheepers & Keller, 2022).…”
