Hacking Weight-loss with Brain Science

Financial rewards for weight-loss and exercise work…but only if you take the money away at the end for non-performance. Rewards are just not as effective as punishments! [Study: Framing Financial Incentives to Increase Physical Activity Among Overweight and Obese Adults: A Randomized, Controlled Trial] This result is, of course, very consistent with Dr. Daniel Kahneman’s work in behavioral economics, memory, and our perception of happiness. One of the key points is how we assign value on items that we already owe versus those that we are considering acquiring. Consider your house (if you own one) or your car. Would you sell it for the same amount of money as you would be willing to buy it for? The answer is no! We value what we own far more than other people’s stuff. Our reaction to ownership is emotional. Mathematics of equivalence just doesn’t penetrate how we feel through to our judgement. Consider the following social incentive program: At the start of my weight-loss program, I get $50 to lose 10 pounds over a 6 months period. At the end of that time period, I only lose 4 pounds. I have to give back $30 — that’s the deal, right? I…

Sizing Up Consciousness by Its Bits

Zimmer, C., (2010). “Sizing Up Consciousness by Its Bits.” NYTimes.com. Visited on October 3, 2010: http://www.nytimes.com/2010/09/21/science/21consciousness.html Carl Zimmer’s article “Sizing Up Consciousness by Its Bits” for The New York Times seeks to introduce and explore a relatively new area of research into human consciousness. In interviews with the medical researcher Dr. Giulio Tononi, the article discusses current and past conceptions of consciousness and its’ implications for our interactions with each other and with our environment. Given the importance of consciousness in everyday human life, one would reasonably assume that at this time science would have a detailed understanding of consciousness and how it functions. This is not the case, however. Despite centuries of philosophical debate, medical research, and technological development, humans are largely in the dark, so to speak, about what creates and maintains the spark of consciousness. In the context of our currently vague understanding, Dr. Tononi’s research proposes a novel way of conceptualizing consciousness. Dr. Tononi’s goal is to apply the theories of informational networks to the human brain, in a method he terms “Integrated Information Theory.” This theory, hereafter referred to as IIT, seeks to understand the human brain as an integrated network of nodes (neurons in…
