Positive affect — cheerfulness — was positively related to students’ self-rated academic abilities, self-predicted likelihoods of various college outcomes, self-stated major and academic-degree intentions, and self-reported subjective college outcomes, but negatively related to most objective college-success variables (e.g., cumulative college grade-point average) recorded by the institution of matriculation, and not related to objective college outcomes reported by the student.

Positive affect was thus associated with “positive illusions” about college-success variables.
