# psych: sometimes chickens remain optimistic despite exposure to stress

<< Chickens that grow up in an environment that they perceive as more diverse and manageable, retain an optimistic view of life and cope with stress better than individuals that grow up in more sterile surroundings >>

# brain: a new learning theory; the role of weak synapses

AA << demonstrate a new type of abundant cooperative nonlinear dynamics where learning is attributed solely to the nodes, instead of the network links which their number is significantly larger >>

<< The network dynamics is now counterintuitively governed by the weak links, which previously were assumed to be insignificant >>

# web: facebook (etc) data, a big correlated lump, harder to delete (then disappear)

<< Information on users' personalities or 'psychographics' was just a modest part of how the model targeted citizens. It was not a personality model strictly speaking, but rather one that boiled down demographics, social influences, personality and everything else into a big correlated lump >>. Matthew Hindman.

<< If Facebook is that hard to leave, just think about what will happen as virtual reality becomes more popular. The powerful algorithms that manipulate Facebook users are not nearly as effective as VR will be, with its full immersion >>

<< As Sean Parker, founding president of Facebook, admits, the narcotic-like, slot-machine effects were consciously designed into the platform right from the start. As Parker bravely confesses, they "understood this consciously," but they “did it anyway.” >>

# behav: more about homebodies vs natural explorers

<< Some species of roundworms are just one millimeter long. Their brains have only 302 neurons, compared to our own 86 billion, and lack any recognizable breathing system. They share only 35 percent of their DNA with human beings >>

<< But we have more in common with these creatures, known to scientists by their Latin name Caenorhabditis elegans (C. elegans), than one might think. Hidden in that 35 percent are clues to the origins of our behavior >> Andres Bendesky.

# brain: actually there is chaos in the brain

<< Besides some empirical findings of chaos at different time scales, the focus is on theoretical modeling of change processes explaining and simulating chaotic dynamics. It will be illustrated how some common factors of psychotherapeutic change and psychological hypotheses on motivation, emotion regulation, and information processing of the client's functioning can be integrated into a comprehensive nonlinear model of human change processes >>
