Three perspectives on social decision-making
The three essays herein explore social decision-making at various scopes and for various ends. At the biological level, substantial progress has been made at the neural level in characterizing the dopaminergic and frontostriatal mechanisms mediating how we learn to adapt in such settings. Chapter …

Social Decision-Making in Bonobos and Chimpanzees
… are natural politicians. We obsessively collect social information that is both observable (e.g., about third-party relationships) and unobservable (e.g., about others’ psychological states), and we strategically employ that information to manage our cooperative and competitive relationships. To …

Self-control, expectations, and patience : essays on social decision making
… and insufficiently adjust away from them when making transfer decisions. Thus, depending on the nature of the initial endowments, individuals may reveal either increased altruism or increased selfishness under self-regulatory depletion. Essay 2: Relative to Them: How Better Brands Reduce …

Two Essays of Other-Regarding Preferences' Influence on Social Decision Making
… Reciprocal preferences represent how a decision maker gains an additional positive utility when it responds to a kind action with a kind action or to an unkind action with an unkind action. I incorporate reciprocal preferences in a two-stage game that predicts the decision of each …

The Neural Correlates of Guilt and Restitution During a Social Decision Making Task
Guilt is a social emotion that promotes prosocial and moral behaviours. It arises as a result of harming another individual, serving as a prompt for the guilty individual to take reparative actions, known as restitution. The neural regions that are involved in guilt and restitution, however, are …

The Role of Social Cognition and Person Perception in Economic Social Decision-Making
<p>Social decision-making is often complex, requiring the decision-maker to make social inferences about another person in addition to engaging traditional decision-making processes. However, until recently, much research in neuroeconomics and behavioral economics has examined social …

Mental health and social decision making: How depression alters the way we trust
… but there is little research on how it affects social decision making. This dissertation addresses the direct impact of depression on the prosocial behaviours that influence economic outcomes, specifically trust and trustworthiness, rather than the economic outcomes themselves. Using …

DISSECTING THE NEURAL CIRCUITRY BEHIND SOCIAL DECISION-MAKING PROCESSES BY DIRECT AND OBSERVATIONAL LEARNING
Gli esseri umani sono animali sociali che raramente vivono in completo isolamento. Pertanto, le nostre decisioni spesso prendono la forma di decisioni sociali, che riguardano altri interlocutori e possibilmente vengono influenzate da essi. I processi decisionali possono portare, a loro volta, a …

The introduction of adaptive social decision-making in the mathematical modelling of egress behaviour
… the occupant's behaviour, the occupant's decision-making process and the eventual occupant behaviour. The mechanisms implemented within the evacuation models presently available were then investigated to determine the current effectiveness of evacuation modelling. This investigation …

The neural correlates of social and non-social decision-making in resolving complex, dynamic uncertainty
… uncertainty is a foundational challenge for social cognition research. Naturalistic stimuli are a powerful tool for modeling these processes, but the cognitive and neural dynamics that govern real-time appraisal during complex narratives remain underexplored. Across three studies, this …

Neural basis of private and social decision-making: new insights from transcranial ultrasound stimulation and multivariate analysis
Value-based decision-making is a complex process that requires the integration of many pieces of information, or decision variables, to choose among several options. These decision variables include the expected value of an option, its associated risk, or the anticipation of the emotions that one …

Social and economic decision-making in Urbach-Wiethe Disease
… the basolateral amygdala as indispensable for social decision-making. This finding has not yet been translated to humans, and has even been partially contradicted by previous findings in patients with amygdala lesions that show generous economic investments in strangers. This thesis therefore …

An Investigation Into The Neural Nature Of Persecutory Ideation
… In the first study we employed a novel economic social decision-making task in two samples during neuroimaging. We demonstrated a dorsal anterior cingulate and anterior insula (dACC-AI) network, a left frontal-parietal (lF-P) network, and a ventral medial orbital prefrontal (vmPFC/OFC) network …

Orbitofrontal Cortex and Social Processing in Rodent Models
Social processing is the reception, interpretation, and reciprocation of social information and is critical for mental health. The neural structures, circuits, and substrates regulating these complex mechanisms are not well understood. Social processing in the form of social safety learning, as …

Neurogenomic dynamics following social interactions in male threespined sticklebacks
Social interactions provoke changes in brain and behavior, however molecular changes associated with social interactions remain obscure. This thesis explored the neurogenomic responses to aggressive and affiliative social interactions in male threespined sticklebacks (Gasterosteus aculeatus), a …

Addressing Relationships among Moral Judgment Development, Narcissism, and Electronic Media and Communication Devices
… certain types of technological devices (i.e. social networking websites, cell phones, etc.) may have adverse effects social decision-making and self-presentation. The current study, therefore, addresses the relationships among moral judgment development, narcissism, and electronic media and …

Neurogenomic architecture of honey bee social behavior
Animals adaptively navigate complex social interactions, respond to social signals, and modify behavior to meet the demands of a changing environment. To do so, social experience must be embedded in the nervous system to modify behavior in anticipation of future events. How social information is …

The power of randomized algorithms : from numerical linear algebra to biological systems
… in ant colonies, which is a key primitive in social decision-making and task allocation. We define a basic computational model and show how agents in this model can estimate their density using a simple random-walk-based algorithm. We also consider simple randomized algorithms for …

Understanding social function in psychiatric illnesses through computational modeling and multiplayer games
Impaired social functioning conferred by mental illnesses has been constantly implicated in previous literatures. However, studies of social abnormalities in psychiatric conditions are often challenged by the difficulties of formalizing dynamic social exchanges and quantifying their neurocognitive …
