Figure 2. Performance on the rodent Iowa Gambling Task.

Figure 2

(A) In young-adult males and females (approx. 3 months old) there was a positive correlation between task performance on the rIGT, as indicated by the number of advantageous choices made during the last block of 10 trials, and %LG (n = 24, r = 0.521, p = 0.009). Thus, animals with higher LG scores perform better on a higher cognitive decision-making task. (B) When dividing the experimental group in ‘Low’ and ‘High’ LG animals by median split, a significant interaction effect between %LG and trial block emerged (10 trials per block; repeated measures ANOVA, main effect of group: F(1,22) = 6.485, p = 0.018; LG-group * trial block interaction: F(11,242) = 1.807, p = 0.05; trial block: F(11,242) = 14.544, p = 0.001). This suggests delayed learning in the ‘Low’ LG group, particularly in the first part of the task.
