“…Existing measures of persistence and related motivational factors typically take the form of subjective self-report or observer-report surveys that may be biased by prior knowledge of achievement (Choi, Mogami, & Medalia, 2010; Cloninger, Przybeck, Svrakic, & Wetzel, 1994; Doherty-Bigara & Gilmore, 2016; Onatsu-Arvilommi & Nurmi, 2000; Pintrich, Smith, Garcia, & McKeachie, 1991, 1993; Steinberg et al, 2007) and are often domain-specific (e.g., academic achievement; Onatsu-Arvilommi & Nurmi, 2000; Pintrich et al, 1991, 1993; Zhang, Nurmi, Kiuru, Lerkkanen, & Aunola, 2011). Of the few behavioral measures of persistence, most examine time spent on challenging tasks before deciding to quit (for review, see Leyro, Zvolensky, & Bernstein, 2010).…”
