    The rupture and repair of cooperation in borderline personality disorder (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-08-09
    Description: To sustain or repair cooperation during a social exchange, adaptive creatures must understand social gestures and the consequences when shared expectations about fair exchange are violated by accident or intent. We recruited 55 individuals afflicted with borderline personality disorder (BPD) to play a multiround economic exchange game with healthy partners. Behaviorally, individuals with BPD showed a profound incapacity to maintain cooperation, and were impaired in their ability to repair broken cooperation on the basis of a quantitative measure of coaxing. Neurally, activity in the anterior insula, a region known to respond to norm violations across affective, interoceptive, economic, and social dimensions, strongly differentiated healthy participants from individuals with BPD. Healthy subjects showed a strong linear relation between anterior insula response and both magnitude of monetary offer received from their partner (input) and the amount of money repaid to their partner (output). In stark contrast, activity in the anterior insula of BPD participants was related only to the magnitude of repayment sent back to their partner (output), not to the magnitude of offers received (input). These neural and behavioral data suggest that norms used in perception of social gestures are pathologically perturbed or missing altogether among individuals with BPD. This game-theoretic approach to psychopathology may open doors to new ways of characterizing and studying a range of mental illnesses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4105006/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4105006/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉King-Casas, Brooks -- Sharp, Carla -- Lomax-Bream, Laura -- Lohrenz, Terry -- Fonagy, Peter -- Montague, P Read -- DA11723/DA/NIDA NIH HHS/ -- F32 MH078485/MH/NIMH NIH HHS/ -- MH078485/MH/NIMH NIH HHS/ -- MH52797/MH/NIMH NIH HHS/ -- NS045790/NS/NINDS NIH HHS/ -- R01 DA011723/DA/NIDA NIH HHS/ -- R01 MH052797/MH/NIMH NIH HHS/ -- R01 NS045790/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2008 Aug 8;321(5890):806-10. doi: 10.1126/science.1156902.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Computational Psychiatry Unit and Department of Neuroscience, Baylor College of Medicine, 1 Baylor Plaza, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18687957" target="_blank"〉PubMed〈/a〉

    Getting to know you: reputation and trust in a two-person economic exchange (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-04-02
    Description: Using a multiround version of an economic exchange (trust game), we report that reciprocity expressed by one player strongly predicts future trust expressed by their partner-a behavioral finding mirrored by neural responses in the dorsal striatum. Here, analyses within and between brains revealed two signals-one encoded by response magnitude, and the other by response timing. Response magnitude correlated with the "intention to trust" on the next play of the game, and the peak of these "intention to trust" responses shifted its time of occurrence by 14 seconds as player reputations developed. This temporal transfer resembles a similar shift of reward prediction errors common to reinforcement learning models, but in the context of a social exchange. These data extend previous model-based functional magnetic resonance imaging studies into the social domain and broaden our view of the spectrum of functions implemented by the dorsal striatum.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉King-Casas, Brooks -- Tomlin, Damon -- Anen, Cedric -- Camerer, Colin F -- Quartz, Steven R -- Montague, P Read -- DA11723/DA/NIDA NIH HHS/ -- DA14883/DA/NIDA NIH HHS/ -- MH52797/MH/NIMH NIH HHS/ -- NS045790/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2005 Apr 1;308(5718):78-83.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Neuroimaging Laboratory, Department of Neuroscience, Baylor College of Medicine, One Baylor Plaza, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15802598" target="_blank"〉PubMed〈/a〉

    Agent-specific responses in the cingulate cortex during economic exchanges (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-05-20
    Description: Interactions with other responsive agents lie at the core of all social exchange. During a social exchange with a partner, one fundamental variable that must be computed correctly is who gets credit for a shared outcome; this assignment is crucial for deciding on an optimal level of cooperation that avoids simple exploitation. We carried out an iterated, two-person economic exchange and made simultaneous hemodynamic measurements from each player's brain. These joint measurements revealed agent-specific responses in the social domain ("me" and "not me") arranged in a systematic spatial pattern along the cingulate cortex. This systematic response pattern did not depend on metrical aspects of the exchange, and it disappeared completely in the absence of a responding partner.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tomlin, Damon -- Kayali, M Amin -- King-Casas, Brooks -- Anen, Cedric -- Camerer, Colin F -- Quartz, Steven R -- Montague, P Read -- DA11723/DA/NIDA NIH HHS/ -- DA14883/DA/NIDA NIH HHS/ -- MH52797/MH/NIMH NIH HHS/ -- NS045790/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2006 May 19;312(5776):1047-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Neuroimaging Laboratory, Department of Neuroscience, Baylor College of Medicine, 1 Baylor Plaza, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16709783" target="_blank"〉PubMed〈/a〉
