Mean number of cards chosen. The results of two factors (repeated measurement) ANOVA (Gain-loss frequencies (gain vs. loss) × Values (± 200 vs. ± 100)) showed a significant effect of gain-loss frequency. Subjects selected more cards from decks A and B than decks C and D (F (1, 47) = 26.41, p < .01). The value effect with of the paired t-test is significant (t (47) = 2.60, p < .05) under high-frequency gain (+200 vs. +100), but not significant (t (47) = 0.72, p = .48) under high-frequency loss (-200 vs. -100). None of the interaction effects are statistically significant (F (1, 47) = 1.88, p = .18).
