    • Adolescent-specific patterns of behavior and neural activity during social reinforcement learning 

      Jones, Rebecca M.; Somerville, Leah; Li, Jian; Ruberry, Erika J.; Powers, Alisa; Mehta, Natasha; Dyke, Jonathan; Casey, B. J. (Springer Verlag, 2014)
      Humans are sophisticated social beings. Social cues from others are exceptionally salient, particularly during adolescence. Understanding how adolescents interpret and learn from variable social signals can provide insight ...

    • Adolescents let sufficient evidence accumulate before making a decision when large incentives are at stake 

      Teslovich, Theresa; Mulder, Martijn; Franklin, Nicholas T.; Ruberry, Erika J.; Millner, Alexander J; Somerville, Leah; Simen, Patrick; Durston, Sarah; Casey, B. J. (Wiley-Blackwell, 2013)
      Adolescent decision-making has been described as impulsive and suboptimal in the presence of incentives. In this study we examined the neural substrates of adolescent decision-making using a perceptual discrimination task ...

    • Asymmetric neural tracking of gain and loss magnitude during adolescence 

      Insel, Catherine; Somerville, Leah (Oxford University Press (OUP), 2018)
      Adolescence has been characterized as a developmental period of heightened reward seeking and attenuated aversive processing. However, it remains unclear how the neural bases of distinct outcome valuation processes shift ...

    • Consequences for Peers Differentially Bias Computations About Risk Across Development 

      Powers, Katherine; Yaffe, Gideon; Hartley, Catherine; Davidow, Juliet; Kober, Hedy; Somerville, Leah (American Psychological Association (APA), 2018-05)
      Adolescents routinely take risks that impact the well-being of the friends they are with. However, it remains unclear when and how consequences for friends factor into decisions to take risks. Here we used an economic ...

    • Interactions Between Transient and Sustained Neural Signals Support the Generation and Regulation of Anxious Emotion 

      Somerville, Leah; Wagner, D. D.; Wig, G. S.; Moran, Joe Michael; Whalen, P. J.; Kelley, W. M. (Oxford University Press (OUP), 2013)
      Anxious emotion can manifest on brief (threat response) and/or persistent (chronic apprehension and arousal) timescales, and prior work has suggested that these signals are supported by separable neural circuitries. This ...

    • Mechanisms of motivation–cognition interaction: challenges and opportunities 

      Braver, Todd S.; Krug, Marie K.; Chiew, Kimberly S.; Kool, Wouter; Westbrook, J. Andrew; Clement, Nathan J.; Adcock, R. Alison; Barch, Deanna M.; Botvinick, Matthew M.; Carver, Charles S.; Cools, Roshan; Custers, Ruud; Dickinson, Anthony; Dweck, Carol S.; Fishbach, Ayelet; Gollwitzer, Peter M.; Hess, Thomas M.; Isaacowitz, Derek M.; Mather, Mara; Murayama, Kou; Pessoa, Luiz; Samanez-Larkin, Gregory R.; Somerville, Leah (Springer Science + Business Media, 2014)
      Recent years have seen a rejuvenation of interest in studies of motivation–cognition interactions arising from many different areas of psychology and neuroscience. The present issue of Cognitive, Affective, & Behavioral ...

    • The Medial Prefrontal Cortex and the Emergence of Self-Conscious Emotion in Adolescence 

      Somerville, Leah; Jones, R. M.; Ruberry, E. J.; Dyke, J. P.; Glover, G.; Casey, B. J. (Association for Psychological Science, 2013)
      In the present study, we examined the relationship between developmental modulation of socioaffective brain systems and adolescents’ preoccupation with social evaluation. Child, adolescent, and adult participants viewed ...

    • Teens Impulsively React rather than Retreat from Threat 

      Dreyfuss, Michael; Caudle, Kristina; Drysdale, Andrew T.; Johnston, Natalie E.; Cohen, Alexandra O.; Somerville, Leah; Galván, Adriana; Tottenham, Nim; Hare, Todd A.; Casey, B.J. (S. Karger AG, 2014)
      There is a significant inflection in risk taking and criminal behavior during adolescence, but the basis for this increase remains largely unknown. An increased sensitivity to rewards has been suggested to explain these ...
