“…Although many studies have highlighted the effect of fatigue on test takers/givers' performance on language tests, (e.g., Bendig, 1955;Constable & Andrich 1984;Cumming et al, 2002;Cumming, 1990;Drave, 2011;Ling et al, 2014;Lumley & McNamara, 1995;Massey, 1977;Schumm & Vaughn, 1991), very little is known about its effects on a raters' scoring quality in speaking and writing tasks (Drave, 2011;Ling et al, 2014). Also, results of studies regarding the effect of fatigue in the literature were quite conflicting in the sense that some suggested that fatigue can affect human judgments' significantly in language tests (e.g., Tucker, 1948;Cumming, 1954;Bendig, 1955;Massey, 1977;Wohlhueter, 1966;Liu et al, 2004;Drave, 2011), whereas others argued that the effect of fatigue on test-takers', or raters' judgments is not significant (e.g., Wohlhueter, 1966;Hiramatsu, 2000;Goodall 2011;Sprouse, 2007).…”
