Our belief as to whether we will likely succeed or fail at a given task—and the consequences of winning or losing—directly affects the levels of neural effort put forth in movement-planning circuits in the human cortex, according to a new brain-imaging study by Caltech neuroscientists.

The process of learning requires the sophisticated ability to constantly update our expectations of future rewards so we may make accurate predictions about those rewards in the face of a changing environment. Although exactly how the brain orchestrates this process remains unclear, a new study by researchers at the California Institute of Technology (Caltech) suggests that a combination of two distinct learning strategies guides our behavior.

Biologists from Caltech and Yale University have identified two genes, the leucokinin neuropeptide and the leucokinin receptor, that appear to regulate meal sizes and frequency in fruit flies. Both genes have mammalian counterparts that seem to play a similar role in food intake, indicating that the steps that control meal size and meal frequency are not just behaviorally similar but are controlled by the same genes throughout the animal kingdom.

Parents pursuing adoption within the United States have strong preferences regarding the types of babies they will apply for, tending to choose non-African-American girls, and favoring babies who are close to being born as opposed to those who have already been born or who are early in gestation. These preferences are significant and can be quantified in terms of the amount of money the potential adoptive parents are willing to pay in finalizing their adoption.

Economists and neuroscientists from Caltech have shown that they can use information obtained through fMRI measurements of whole-brain activity to create feasible, efficient, and fair solutions to one of the stickiest dilemmas in economics, the public goods free-rider problem—long thought to be unsolvable. This is one of the first-ever applications of neurotechnology to real-life economic problems, the researchers note.

When you're on a diet, deciding to skip your favorite calorie-laden foods and eat something healthier takes a whole lot of self-control--an ability that seems to come easier to some of us than others. Now, scientists from the California Institute of Technology (Caltech) have uncovered differences in the brains of people who are able to exercise self-control versus those who find it almost impossible.

When it comes to intellectual curiosity and creativity, a market economy in which inventors can buy and sell shares of the key components of their discoveries actually beats out the winner-takes-all world of patent rights as a motivating force, according to a California Institute of Technology (Caltech)-led team of researchers.

"Economics is the field that has used game theory the most broadly to understand bargaining, pricing, firm competition, incentive contracts, and more," explains Camerer.

In a strategic game, the success of any player depends not just on his or her own actions, but on the behavior of every other player in the game. To be successful, players must not only pay attention to what other players do, but also how they are thinking.

In the biblical story in which two women bring a baby to King Solomon, both claiming to be the mother, he suggests dividing the child so that each woman can have half. Solomon's proposed solution, meant to reveal the real mother, also illustrates an issue central to economics and moral philosophy: how to distribute goods fairly.
