Enhanced incidental learning of faces encoded during states of high curiosity. (A) Recognition discriminability (Pr values) was higher for faces presented during states of high curiosity compared to low curiosity trials. (B) Brain activity elicited by onset of each trivia question was analyzed based on whether the face that was subsequently presented on the same trial was recognized or forgotten on the post-scan face recognition test. (C) The neural interaction between anticipatory curiosity and memory was highly correlated with the curiosity-driven memory benefit for neutral faces. The scatter plots show significant, positive correlations between the inter-subject variability in the curiosity-driven memory benefit (plotted on the y-axis) and in activity for the bilateral SN/VTA (left) and the right hippocampus (right). Each data point represents one participant. HCR/ HCF = High curiosity recognized / forgotten, LCR/ LCF = low curiosity recognized / forgotten.
