The War on Reason - Paul Bloom Aristotle’s definition of man as a rational animal has recently taken quite a beating. Part of the attack comes from neuroscience. Pretty, multicolored fMRI maps make clear that our mental lives can be observed in the activity of our neurons, and we’ve made considerable progress in reading someone’s thoughts by looking at those maps. It’s clear, too, that damage to the brain can impair the most-intimate aspects of ourselves, such as the capacity to make moral judgments or to inhibit bad actions. This conception of what it is to be a person fits poorly with our sense of how we live our everyday lives. “Pig valves.” I bristle at that just, but the evidence is overwhelming that Charlie is right. Another attack on rationality comes from social psychology. Such statements have produced a powerful backlash. For the most part, I’m on the side of the neuroscientists and social psychologists—no surprise, given that I’m a psychologist myself. Other examples of biochemical puppetry abound.

Sean Carroll: The arrow of time (Part 1 of 2) Loading … Comment on this Talk 158 total comments In Part 1 of his lecture at the University of Sydney, cosmologist Sean Carroll gives an entertaining and thought-provoking talk about the nature of time, the origin of entropy, and how what happened before the Big Bang might be responsible for the arrow of time we observe today. A physicist, cosmologist and gifted science communicator, Sean Carroll is asking himself -- and asking us to consider -- questions that get at the fundamental nature of the universe. 13 Way, way out there Curated by TED Travel across the universe (or is it universes?)

Delval - Desarrollo I Prefacio domingo, 01 de agosto de 2010 06:30 p.m. · Sin duda uno de los fenómenos mas fascinantes que nos es dado presenciar, para el que además estamos muy sensibilizados, es el desarrollo de un niño, el esfuerzo por crecer, en todos los sentidos, y pasar del desvalido que todos nosotros hemos sido en el nacimiento a convertirnos en adultos. · El objetivo de este libro no es otro que intentar describir como la niña se hace mujer, como el niño se hace hombre, como el recién nacido se convierte en ser humano, como un ser que, cuando viene al mundo parece tan inmaduro, débil, dependiente y expuesto a grandes peligros, logra sobrevivir y llega a convertirse en una persona autónoma, hábil, dotado de capacidades muy complejas, capaz de relacionarse con los otros, y como esas criaturas se han extendido por todo el planeta, y amenazan con invadir otros mundos. · Lo característico de los hombres es que son mucho mas incompletos como seres humanos cuando nacen que las cabras o los gorriones

How consciousness works – Michael Graziano Scientific talks can get a little dry, so I try to mix it up. I take out my giant hairy orangutan puppet, do some ventriloquism and quickly become entangled in an argument. I’ll be explaining my theory about how the brain — a biological machine — generates consciousness. Kevin is the perfect introduction. Many thinkers have approached consciousness from a first-person vantage point, the kind of philosophical perspective according to which other people’s minds seem essentially unknowable. Lately, the problem of consciousness has begun to catch on in neuroscience. I believe that the easy and the hard problems have gotten switched around. In a period of rapid evolutionary expansion called the Cambrian Explosion, animal nervous systems acquired the ability to boost the most urgent incoming signals. Attention requires control. The most basic, measurable, quantifiable truth about consciousness is simply this: we humans can say that we have it I call this the ‘attention schema theory’.

12 Things Men/Women do differently. The Brains of the Animal Kingdom SimSensei 2011-present Project Leader: Mark Bolas, Jonathan Gratch, Arno Hartholt, Stacy Marsella and David Traum Principal investigators: Albert “Skip” Rizzo and Louis-Philippe Morency Summary The University of Southern California Institute for Creative Technologies’ (ICT), pioneering efforts within DARPA’s Detection and Computational Analysis of Psychological Signals (DCAPS) project encompass advances in the artificial intelligence fields of machine learning, natural language processing and computer vision. Goals This effort seeks to enable a new generation of clinical decision support tools and interactive virtual agent-based healthcare dissemination/delivery systems that are able to recognize and identify psychological distress from multimodal signals. Capabilities ICT is expanding its expertise in automatic human behavior analysis to identify indicators of psychological distress in people.

The Science of Why We Don't Believe Science Illustration: Jonathon Rosen "A MAN WITH A CONVICTION is a hard man to change. Tell him you disagree and he turns away. Show him facts or figures and he questions your sources. Festinger and several of his colleagues had infiltrated the Seekers, a small Chicago-area cult whose members thought they were communicating with aliens—including one, "Sananda," who they believed was the astral incarnation of Jesus Christ. Through her, the aliens had given the precise date of an Earth-rending cataclysm: December 21, 1954. Festinger and his team were with the cult when the prophecy failed. Read also: the truth about Climategate.At first, the group struggled for an explanation. From that day forward, the Seekers, previously shy of the press and indifferent toward evangelizing, began to proselytize. In the annals of denial, it doesn't get much more extreme than the Seekers. We apply fight-or-flight reflexes not only to predators, but to data itself.

Psychological Wellness: What Has Happened to our Understanding of Mental Health? 5 examples of how the languages we speak can affect the way we think Keith Chen (TED Talk: Could your language affect your ability to save money?) might be an economist, but he wants to talk about language. For instance, he points out, in Chinese, saying “this is my uncle” is not as straightforward as you might think. In Chinese, you have no choice but to encode more information about said uncle. The language requires that you denote the side the uncle is on, whether he’s related by marriage or birth and, if it’s your father’s brother, whether he’s older or younger. “All of this information is obligatory. This got Chen wondering: Is there a connection between language and how we think and behave? While “futured languages,” like English, distinguish between the past, present and future, “futureless languages” like Chinese use the same phrasing to describe the events of yesterday, today and tomorrow. But that’s only the beginning. Featured illustration via iStock.

What Do Blind People Find Attractive? Researchers Capture A Zebrafish's Thought Process On Video What's in a thought? When it comes to the zebrafish, now you can see for yourself. For the first time, Japanese researchers have captured video of thoughts moving through a zebrafish's brain. By genetically modifying a transparent zebrafish larvae to create a glow in reaction to calcium ions--which skyrocket during neuron activity--scientists could track the regions in the fish's brain activated by the thought process. Researchers released a paramecium, a single-celled zebrafish food source shaped like a grain of rice, and watched the glowing neurological response from the fish. This research could lead to better psychiatric medications, according to Koichi Kawakami, one of the co-authors of the paper in Current Biology. How about we just keep watching the glowing fish?
