“…The construct clear task goals subsumes the example terms (utilized by review sources) including “specified objectives,” “clarity of purpose,” “confidence”; “immediate and unambiguous feedback” subsumes the example constructs “coherent, noncontradictory demands” and “direct feedback”; and “self-efficacy” subsumes the example constructs “self-confidence” and “self-trust.” See Figure 2 and for further details. The premise behind goal- and feedback-related concepts being included in this theme appears to be that if goal (that is, clear goals) and diagnostic information are not clear and immediate (that is, immediate and unambiguous feedback), then the experience may be confusing or overdemanding (and no longer optimally challenging; Cseh, 2016; Drengner et al, 2018; Guertin, 2016; Keller & Landhausser, 2012; Moneta, 2017; Simlesa et al, 2018; Valenzuela et al, 2018). When examining goal type, sources reported that goal congruency (for example, Keller & Landhausser, 2012), personal growth and exploration goals (for example, “seeing how well I can do”; Swann et al, 2016), “open” (that is, nonoutcome orientated) as opposed to “fixed” (that is, outcome orientated) goals (Swann et al, 2017), and task-orientated goals (Csikszentmihalyi, 2014c) result in increased flow.…”
