“…Similarly, Ruthig, Haynes, Perry, and Chipperfield (2007) found optimism to correlated with both cumulative grade point average (r = .32, p < .001) and perceived success, a construct reflecting satisfaction with learning performance (r = .28, p < .001) among their sample of 640 Canadian first-year undergraduates. A fourth study conceptualizing dispositional optimism as a lack of pessimism found lower levels of pessimism to be associated with higher grade point averages (r = -.15, p = .044) in their sample of 235 undergraduate students (Maleva, Westcott, McKellop, McLaughlin, Widman, & College, 2014). Finally, a fifth study used a series of analyses of variance to examine the effects of achievement explanatory style on important student outcomes.…”
