An underlying cause for psychopathic behavior? - 2 views

  • impairment in the emotional aspects of these abilities may account for psychopathic behaviour.
  • ToM is made up of different aspects: a cognitive part, which requires inferences about knowledge and beliefs, and another part which requires the understanding of emotions.
  • striking similarities between the mental impairments observed in psychopaths and those seen in patients with frontal lobe damage.

  • The pattern of impairments in the psychopathic participants showed a remarkable resemblance to those in the participants with frontal lobe damage, suggesting that an underlying cause of the behavioural disturbances observed in psychopathy may be dysfunction in the frontal lobes.
  •  
    Psychopaths are known to be characterized by callousness, diminished capacity for remorse, and lack of empathy. However, the exact cause of these personality traits is an area of scientific debate. The results of a new study, reported in the May 2010 issue of Elsevier's Cortex, show striking similarities between the mental impairments observed in psychopaths and those seen in patients with frontal lobe damage.

Control Consciousness: The Imagery Theory - 0 views

  •  
    Of course, it should be noted that there may be alternate architectures that incorporate forward models satisfying criteria for being sensory. However, the core idea of a forward model does not alone satisfy such criteria. It is also worth noting that the characterization of imagery as the willful reactivation of input systems threatens to make the imagery account collapse into a kind of non-sensory view. This is so if a crucial part of a state's being imagery is its activation of a control signal. (Brain Hammer)

Scientist Finds the Beginnings of Morality in Primate Behavior - New York Times - 0 views

  • Marc Hauser, an evolutionary biologist at Harvard, proposed in his book “Moral Minds” that the brain has a genetically shaped mechanism for acquiring moral rules, a universal moral grammar similar to the neural machinery for learning language.
  • Frans de Waal defends against philosopher critics his view that the roots of morality can be seen in the social behavior of monkeys and apes.

  • Social living requires empathy

  • human morality may be severely limited by having evolved as a way of banding together against adversaries, with moral restraints being observed only toward the in group, not toward outsiders.
  • eciprocity and fairness
  • Chimps are more likely to share food with those who have groomed them.
  • These four kinds of behavior — empathy, the ability to learn and follow social rules, reciprocity and peacemaking — are the basis of sociality.
  • People enforce their society’s moral codes much more rigorously with rewards, punishments and reputation building. They also apply a degree of judgment and reason, for which there are no parallels in animals.
  • Capuchin monkeys show their displeasure if given a smaller reward than a partner receives for performing the same task
  • reason is generally brought to bear only after a moral decision has been reached
  • Morality, he writes, is “a sense of right and wrong that is born out of groupwide systems of conflict management based on shared values.” The building blocks of morality are not nice or good behaviors but rather mental and social capacities for constructing societies “in which shared values constrain individual behavior through a system of approval and disapproval.”
  • Some animals are surprisingly sensitive to the plight of others.

Stages of Brain Development - 0 views

  •  
    From a single fertilised egg of about 0.14 millimetres in diameter, to an adult human being, the neurophysiology of development of the brain and nervous system is nothing short of remarkable. We are born with around 100 billion neurons, and the development of the brain continues long after birth, with dendrites of some neurons in the neocortex continuing to grow well into old age

We Empathize, Therefore We Are: Toward a Moral Neuropolitics - 0 views

  •  
    "Based on recent findings from neuroscience we can plausibly deduce that the mirror neurons of the viewer were engaged by these images of others suffering. The appeal was to the public's awakened sense of compassion and revulsion toward graphic depictions of the wholesale violence, barbarity, and torture routinely practiced on these Atlantic voyages. Rediker notes that the images would instantaneously "make the viewer identify and sympathize with the 'injured Africans' on the lower deck of the ship . . ." while also producing a sense of moral outrage (p. 315, Olson, 2008)."

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

Losers With Winners' Brains - 0 views

  •  
    One of the mysteries of gambling is that even when we should know we're going to lose, we somehow think we're going to win. Dr. Luke Clark, from the Department of Experimental Psychology at the University of Cambridge, may have discovered one of the reasons why. Using MRI, he studied brain activity in people gambling, looking particularly at "near misses" in which a loss seems close to a win. He found that the brain activated the same reward system that is activated in a real win, despite the fact that people report that these near misses are unpleasant.

Where is my mind? - 0 views

  • Is what my robot does when it ‘decides’ to change course a sort of thing which if it had happened inside the robot, ‘I would have had no hesitation in accepting as part of [a] cognitive process?’

  • The mark of the mental is its intensionality (with an ‘s’); that’s to say that mental states have content; they are typically about things.
  • What I should have said isn’t that only what’s literally and unmetaphorically mental has content, but that if something literally and unmetaphorically has content, then either it is mental (part of a mind) or the content is ‘derived’ from something that is mental. ‘Underived’ content (to borrow John Searle’s term) is the mark of the mental; underived content is what minds and only minds have.
  • Externalism needs internalism; but not vice versa. External representation is a side-show; internal representation is ineliminably the main event.
  • your internal model of the world contains stuff that the world itself does not; this happens not just when your beliefs are false but also when they are hypothetical (‘if there are clouds, there will be rain’ can be true even if there aren’t any clouds); or when they are modal (‘it might rain’ can be true even if it doesn’t rain); or when they are in the past or future tense (‘it used to rain here a lot’ can be true even if it doesn’t rain here anymore).

    There is a gap between the mind and the world, and (as far as anybody knows) you need to posit internal representations if you are to have a hope of getting across it. Mind the gap. You'll regret it if you don't. (Jerry Fodor review of Clark)

Disgust as Embodied Moral Judgment - 0 views

  •  
    How, and for whom, does disgust influence moral judgment? In 4 experiments participants made moral judgments while experiencing extraneous feelings of disgust. Disgust was induced in Experiment 1 by exposure to a bad smell, in Experiment 2 by working in a disgusting room, in Experiment 3 by recalling a physically disgusting experience, and in Experiment 4 through a video induction. In each case, the results showed that disgust can increase the severity of moral judgments relative to controls. Experiment 4 found that disgust had a different effect on moral judgment than did sadness. In addition, Experiments 2-4 showed that the role of disgust in severity of moral judgments depends on participants' sensitivity to their own bodily sensations. Taken together, these data indicate the importance - and specificity - of gut feelings in moral judgments.

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.

Flu Vaccine Expected to Protect Against Most U.S. H3N2 Viruses | eMedEvents - 0 views

  •  
    A novel bioinformatics approach can predict vaccine effectiveness for the influenza season, and indicates that the current vaccines are likely to be effective against H3N2 flu viruses in the U.S. 2017/2018 flu season, according to research published online Nov. 29 in F1000 Research. Slobodan Paessler, D.V.M., Ph.D., from the University of Texas Medical Branch, and Veljko Veljkovic, Ph.D., from Biomed Protection, both in Galveston, Texas, used a bioinformatics platform to predict vaccine effectiveness for the 2017/2018 influenza season in the United States. The hemagglutinin HA1 region of 251 and 113 human H3N2 viruses collected in Australia and the United States from July to September 2017 were analyzed. The informational spectrum method-based phylogenetic analysis of H3N2 viruses was performed to serve as a base for predicting vaccine effectiveness. The researchers found that analyses of Australian viruses generated two clusters; the vaccine virus was placed in the smaller group. As a result, the vaccine was predicted not to be efficient against most Australian H3N2 viruses in the 2017 flu season; low vaccine effectiveness was reported in Australia in the 2017 flu season in accordance with this prediction. The U.S. H3N2 viruses were also grouped into two clusters, but the vaccine virus was placed in the largest cluster encompassing 71 percent of analyzed viruses. Consequently, the vaccine effectiveness is expected not to be suboptimal in the United States.

"No evidence of Human Mirror Neurons" - 0 views

  •  
    "Social scientists are often concerned about the importation of poorly understood concepts from the hard sciences into "softer" fields like anthropology or sociology. In my view, the story of mirror neurons shows that the reverse also happens: scores of brilliant neuroscientists were set to work on entities celebrated and, one might say, partly invented because they allowed neuroscience to relate to social concepts, like imitation, culture, and art. Once it got started, the story was one of mutual seduction. The disenchantment, if it takes place at all, may take years. Will the speculative bubble burst? "

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.

  • 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.

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.

  • 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.

Do the Impossible: Know Thyself - 0 views

  • Two main questions arose in my mind during the neuropsychiatric conference. The first was whether any scientific self-understanding was possible. The second was whether, if possible, it was desirable. My answer to both questions was, and is, no.
    • Rudy Garns
       
      Notice the question is whether ANY scientific self-understanding is possible, not just whether we have one now or whether neuroscience alone will provide all the answers.
  • difficult even to conceive of what a scientific self-understanding would actually be like
    • Rudy Garns
       
      So what? Why should we assume we can conceive of it prior to achieving it? It might be complicated. Perhaps it is the wort of thing we approximate over a long period of time through the scientific endeavors of lots of people.
  • How does one develop a universal law that explains an infinite number of unique events that are infused with meaning and intentionality?
    • Rudy Garns
       
      I doubt it will require a single universal law to understand human nature, or the mortivations for human behavior. At best we might develop theories that allow us to predict human behavior fairly accurately. We already try to do this personally; neuroscience, genetics, etc., should enhance those abilities considerably.

  • Nothing is important or significant but conscious thinking makes it so: the type of thinking, moreover, that employs moral categories that are inherently non-natural.
    • Rudy Garns
       
      it certainly doesn't seem right that conscious thinking lies behind our moral (or other) values. But even so, why would that make them non-natural?
  • The fact is that, however many factors you examine, you cannot fully explain behaviour, not even relatively simple behaviour.
    • Rudy Garns
       
      Do we need to fully explain behavior? Is it full explanation or nothing? Might there not be value in partial explanations?
  •  
    Is it to be full understanding or nothing? I should think there would be some value in enough understanding to make useful predictions. His position is that a scientific understanding of man is undesirable, but I thinnk there is something very desirable about useful predictions.

Intranasal Administration of Oxytocin Increases Envy and Schadenfreude (Gloating) - 0 views

  •  
    Envy and schadenfreude (gloating over the other's misfortune) are social emotions widely agreed to be a symptom of the human social tendency to compare one's payoffs with those of others. Given the important social components of envy and gloating, we speculated that oxytocin may have a modulating effect on the intensity of these emotions.

Slide show: How your brain works - 0 views

  •  
    Your brain contains billions of nerve cells arranged in patterns that coordinate thought, emotion, behavior, movement and sensation. A complicated highway system of nerves connects your brain to the rest of your body, so communication can occur in split seconds. Think about how fast you pull your hand back from a hot stove. While all the parts of your brain work together, each part is responsible for a specific function - controlling everything from your heart rate to your mood.
