    "abstract": "Mounting evidence suggests that human category learning is\nachieved by multiple qualitatively distinct biological and\npsychological systems. In an information-integration (II)\ncategorization task, optimal performance requires switching\naway from rule and adopting a procedural response strategy.\nHowever, many participants perseverate with rules. This article\nattempts at understanding the difference between optimal and\nsuboptimal participants in II categorization. To this end, we\ncollected data in the Iowa Gambling Task (IGT) and an II\ncategorization task. Performance in the IGT was used to\nestimate each participant’s sensitivity to reward, punishment,\nand propensity to explore. The results show that optimal\nparticipants in the II task explored more in the IGT than\nsuboptimal participants. However, optimal participants in the\nII task did not show higher sensitivity to punishment or lower\nsensitivity to reward. We conclude by discussing the\nimplications of these findings on system-switching and\ntheoretical work on multiple-systems model of perceptual\ncategory learning.",
