Neuroscience and Decision Making - 0 views

  •  
    This paper reviews the cognitive neuroscience of decision making and summarizes a talk given by the author at a SOL-UK workshop entitled 'Improving the Decision-Taking Process in Institutions' and held at the London School of Economics on 23rd June, 2006.\n\nAn operational definition of decision making is discussed as it relates to neuroscientific research and application. Neuroanatomical and cortico- subcortical as well as cortico-cortical connections between brain structures are then reviewed as they relate to the decision making process. Finally, while biased toward the individual level of analysis, extrapolations to the larger group environment are also discussed.

Social Decision-Making: Insights from Game Theory and Neuroscience - 0 views

  •  
    By combining the models and tasks of Game Theory with modern psychological and neuroscientific methods, the neuroeconomic approach to the study of social decision-making has the potential to extend our knowledge of brain mechanisms involved in social decisions and to advance theoretical models of how we make decisions in a rich, interactive environment. Research has already begun to illustrate how social exchange can act directly on the brain's reward system, how affective factors play an important role in bargaining and competitive games, and how the ability to assess another's intentions is related to strategic play. These findings provide a fruitful starting point for improved models of social decision-making, informed by the formal mathematical approach of economics and constrained by known neural mechanisms. -- Sanfey 318 (5850): 598 -- Science

Neuroscience and Decision Making - 0 views

  •  
    The purpose of this paper is to provide an integrative review of the area of Neuroscience and its relationship to Behavioral Decision Making. I will start by discussing Prospect theory and the role that neuroscience can play in understanding human behavior under risky situations. I will then discuss the Somatic Marker Hypothesis and its application in decision making. Further, I will highlight some techniques that are used to measure neural responses. Finally, I will end with future avenues of research where Neuroscience techniques can be applied in studying different Marketing phenomena.

Mixing Memory : Emotion, Reason, and Moral Judgment - 0 views

  • emotion and intuition, both of which operate automatically and unconsciously for the most part, play a much larger role than most philosophers and psychologists had previously been willing to admit.
  • VMPC plays a role in encoding the reward value of stimuli, as well as emotions like fear.
  • determines approach and avoidance behavior.
  • ...8 more annotations...
  • patients with damage to the VMPC, who have trouble processing emotional value as a result of that damage, would behave differently in those scenarios than normal individuals (and other brain-damaged patients
  • The standard interpretation of these results is that in the impersonal scenarios, people are making the moral decision using conscious reasoning. Specifically, they are thought to be using utilitarian ethical principles to make the decision to flip the switch and kill one person to save five. In the personal scenarios, however, people tend not to make utilitarian decisions, and researchers therefore believe that they are basing their decision on the emotional response the situation elicits.
  • damage to the VMPC can make decisions related to the value of a stimulus more difficult
  • there was a difference between the normal patients (and brain-damaged elsewhere patients) and the VMPC-damaged patients for the high-conflict personal moral scenarios. The normal and non-VMPC brain-damaged patients said "no" (they wouldn't smother the baby, e.g.) about 80% of the time in response to these scenarios, while the VMPC-damaged patients said no less than 60% of the time (in fact, their response rate was pretty close to 50-50).
  • more rational
  • they just didn't know how to respond to those scenarios
  • unable to decide
  • when people are making these decisions, both the emotional reaction and the moral principle are available at the same time, and one will win out over the other, depending largely on the strength of the emotional response (which is strong in the personal scenarios, and weak in the impersonal ones, at least when they're just being read on paper). This would be inconsistent with strong intuitionist theories of moral judgment.

Brain activity associated with honest and dishonest decisions. - 0 views

  •  
    What makes people behave honestly when confronted with opportunities for dishonest gain? Research on the interplay between controlled and automatic processes in decision making suggests 2 hypotheses: According to the "Will" hypothesis, honesty results from the active resistance of temptation, comparable to the controlled cognitive processes that enable the delay of reward. According to the "Grace" hypothesis, honesty results from the absence of temptation, consistent with research emphasizing the determination of behavior by the presence or absence of automatic processes.

Neural correlates of third party punishment. - 0 views

  •  
    The level of activity in the right dorsolateral prefrontal cortex correlated with the level of responsibility that the volunteers assigned to the defendant, whereas activity in the amygdala, the medial prefrontal cortex and the posterior cingulate cortex predicted punishment magnitude, indicating that distinct neural systems underlie the two processes in legal decision making.

Anterior cingulate cortex - Wikipedia - 0 views

  • the dorsal anterior cingulate cortex is primarily related to rational cognition while the ventral is more related to emotional cognition.

  • ACC response in Stroop task experiments (designed to measure adherence to sequential decision-making paths) remains relatively elevated in typical human subjects, as the alternative - spontaneity - is sacrificed.
  • A typical task that activates the ACC involves eliciting some form of conflict within the participant that can potentially result in an error.
  • inability to detect errors, severe difficulty with resolving stimulus conflict in a Stroop task, emotional instability, inattention, and akinetic mutism
  • difficulty in dealing with conflicting spatial locations in a Stroop-like task and having abnormal ERNs
  • appears to play a role in a wide variety of autonomic functions, such as regulating blood pressure and heart rate, as well as rational cognitive functions, such as reward anticipation, decision-making, empathy and emotion.

Does it make a difference if it is a stranger? What about alternative to the other five victims? What information is the VMPFC working with?

Politika Erotika: DAVID BROOKS: The Morality Line - 0 views

  • There still seems to be such things as selves, which are capable of making decisions and controlling destiny. It’s just that these selves can’t be seen on a brain-mapping diagram, and we no longer have any agreement about what they are.
  • we are renegotiating what you might call the Morality Line, the spot where background forces stop and individual choice — and individual responsibility — begins. The killings happen at a moment when the people who explain behavior by talking about biology, chemistry and social science are assertive and on the march, while the people who explain behavior by talking about individual character are confused and losing ground.
  • now the language of morality is often replaced with the language of determinism. >

  • It’s important knowledge, but it’s had the effect of reducing the scope of the human self. “Man is the measure of all things,” the Greek philosopher Protagoras declared millenniums ago. But in the realm of the new science, the individual is like a cork bobbing on the currents of giant forces: evolution, brain chemistry, stress and upbringing. Human consciousness is merely an epiphenomena of the deep and controlling mental processes that lie within.
