    Processing speed enhances model-based over model-free reinforcement learning in the presence of high working memory functioning.Daniel J. Schad, Elisabeth Jünger, Miriam Sebold, Maria Garbusow, Nadine Bernhardt, Amir-Homayoun Javadi, Ulrich S. Zimmermann, Michael N. Smolka, Andreas Heinz, Michael A. Rapp & Quentin J. M. Huys - 2014 - Frontiers in Psychology 5:117016.
    Theories of decision-making and its neural substrates have long assumed the existence of two distinct and competing valuation systems, variously described as goal-directed vs. habitual, or, more recently and based on statistical arguments, as model-free vs. model-based reinforcement-learning. Though both have been shown to control choices, the cognitive abilities associated with these systems are under ongoing investigation. Here we examine the link to cognitive abilities, and find that individual differences in processing speed covary with a shift from model-free to model-based (...)

  4. Stronger Prejudices Are Associated With Decreased Model-Based Control.Miriam Sebold, Hao Chen, Aleyna Önal, Sören Kuitunen-Paul, Negin Mojtahedzadeh, Maria Garbusow, Stephan Nebe, Hans-Ulrich Wittchen, Quentin J. M. Huys, Florian Schlagenhauf, Michael A. Rapp, Michael N. Smolka & Andreas Heinz - 2022 - Frontiers in Psychology 12.
    Background: Prejudices against minorities can be understood as habitually negative evaluations that are kept in spite of evidence to the contrary. Therefore, individuals with strong prejudices might be dominated by habitual or “automatic” reactions at the expense of more controlled reactions. Computational theories suggest individual differences in the balance between habitual/model-free and deliberative/model-based decision-making.Methods: 127 subjects performed the two Step task and completed the blatant and subtle prejudice scale.Results: By using analyses of choices and reaction times in combination with computational (...)
