[In Press] Translational research in punishment learning

Punishment learning is learning of the causal relationship between responses and their adverse or undesirable consequences. Here, we review our translational approach for understanding whether, when, and how individuals differ in what they learn during punishment, and how these differences in learning may drive persistent poor or maladaptive decisions. We show that individual differences in punishment insensitivity can emerge from differences between individuals in what they learn about punishment (instrumental contingency knowledge), rather than differences in aversive valuation, reward valuation, general (impulsivity), or specific (habit) behavioral control. These differences in instrumental contingency knowledge are shared with and can be studied in other animals. Our approach has strong construct and predictive validity, providing a robust translational platform for studying how punishment learning and decision making may contribute to neuropsychiatric disorders.
