What Makes the Human Mind? - 0 views

  •  
    Across the board, Hauser says, there are signs that animal evolution passed along some capabilities "and then something dramatic happened, a huge leap that enabled humans to break away. Once symbolic representation happened, if the combinatorial capacity was there, things just took off. Precisely how and when this happened, we may never know." (November-December 2008)

The Origin of the Mind - 0 views

    The first step in figuring out how the human mind arose is determining what distinguishes our mental processes from those of other creatures

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.

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.
  • human morality would be impossible without certain emotional building blocks that are clearly at work in chimp and monkey societies

  • other chimpanzees would console the loser.
  • Social living requires empathy
  • reconciliation
  • 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.

Neuroscience: Small, furry … and smart - 0 views

  • Much of the work involves making an adult brain behave more like a younger, more flexible version of itself by increasing the organ's plasticity.
  • neuroscientists using genetic engineering to generate cognitively enhanced animals in a bid to understand memory and learning.
  • Tsien created Doogie by overexpressing a subunit of the NMDA receptor called NR2B. This kept the receptors open for longer, strengthening the synaptic link and making it easier for disparate events to be linked together.
  •  
    Tsien, based at Princeton University in New Jersey at the time, named his creation Doogie after the teenage genius in the television programme Doogie Howser, MD. The work was one of the earliest examples of neuroscientists using genetic engineering to generate cognitively enhanced animals in a bid to understand memory and learning.
