The nascent field of neuroeconomics seeks to ground economic decision making in the biological substrate of the brain. We used functional magnetic resonance imaging of Ultimatum Game players to investigate neural substrates of cognitive and emotional processes involved in economic decision-making. In this game, two players split a sum of money;one player proposes a division and the other can accept or reject this. We scanned players as they responded to fair and unfair proposals.

Game theory and neural basis of social decision making

Humans tend to reduce inequitable distributions. Previous neuroimaging studies have shown that inequitable decisions are related to brain regions that associated with negative emotion and signaling conflict. In the highly complex human social environment, our opinions and behaviors can be affected by social information. In current study, we used a modified dictator game to investigate the effect of social influence on making an equitable decision. We found that the choices of participants in present task was influenced by the choices of peers. The neural responses in the dorsomedial prefrontal cortex, rostral cingulate zone, and insula predicted subsequent conforming behavior in individuals. Additionally, psychophysiological interaction analysis revealed that the interconnectivity between the dorsal striatum and insula was elevated in advantageous inequity influence versus no-social influence conditions.

In its original formulation, game theory seeks to find the strategies that a group of decision makers will converge on, as they try to maximize their.


Social Cognition through the Lens of Cognitive and Clinical Neuroscience

Its centrality in everyday life reflects the neural complexity of social processing and the ubiquity of social cognitive deficits in different pathological conditions. We review these domains from the lens of cognitive neuroscience, i. In the latter case, impairments in one or more of the abovementioned domains represent a prominent concern, or even a core facet, of neurological e. To pave the way for the other papers of this issue, addressing the social cognitive deficits associated with severe acquired brain injury, we will briefly discuss the available evidence on the status of social cognition in normal aging and its breakdown in neurodegenerative disorders. Although the assessment and treatment of such impairments is a relatively novel sector in neurorehabilitation, the evidence summarized here strongly suggests that the development of remediation procedures for social cognitive skills will represent a future field of translational research in clinical neuroscience.

Neuroeconomics is an interdisciplinary field that seeks to explain human decision making , the ability to process multiple alternatives and to follow a course of action. It studies how economic behavior can shape our understanding of the brain , and how neuroscientific discoveries can constrain and guide models of economics. It combines research from neuroscience , experimental and behavioral economics , and cognitive and social psychology. Neuroeconomics studies decision making by using a combination of tools from these fields so as to avoid the shortcomings that arise from a single-perspective approach. In mainstream economics , expected utility EU and the concept of rational agents are still being used.

This paper introduces an emerging interdisciplinary research field, namely neuroeconomics, which uses the neuroscientific methods to investigate the neural systems supporting economically relevant behaviors. Traditional economic research is restricted to the level of describing decision behaviors, leaving the cognitive mechanisms behind them unknown. It also fails to predict many decision behaviors in real life.

Беккер быстро проделал это со всеми буквами. Он никогда не думал, что четыре слова могут сделать его таким счастливым: IM GLAD WE MET Что означало: Я рада, что мы встретились. Он быстро нацарапал на программке ответ и протянул Сьюзан: LDSNN Сьюзан, прочитав, просияла. ME TOO, что означало: Я .

The Neural Basis of Social Influence in a Dictator Decision

Перед сердечным приступом мистер Танкадо не почувствовал ничего, кроме легкого укола. - Травматическая пуля, - задумчиво повторил Беккер.

Это хорошо защищенный почтовый ящик, и мне лишь случайно удалось на него наткнуться.  - Он выдержал паузу.  - Итак, если Танкадо хотел, чтобы мы обнаружили его почту, зачем ему понадобился секретный адрес. Сьюзан снова задумалась. - Может быть, для того, чтобы вы не заподозрили, что это приманка.

Neuroeconomics: Opening the “black box” behind the economic behavior

За дверью послышалось движение, раздались голоса. Он постучал. Послышался голос с сильным немецким акцентом: - Ja.
