Joshua Greene, Harvard psychologist, posits that we have two competing moral circuits in our brains: a utilitarian, rational, cost-benefits circuit and an emotional circuit. Both circuits battle for dominance in the brain's ventromedial prefrontal cortex. When dilemmas produce vivid images in our heads, we tend to respond emotionally, due to our natural wiring. Take away the pictures - the brain goes into rational, calculation mode. In another experiment, Greene and a colleague, Amit, also found that people who think visually make more emotional moral judgments, whereas verbal people make more rational calculations.

A really interesting study combining linguistics and behavioral economics. "To judge a risk more clearly, it may help to consider it in a foreign language: A series of experiments on more than 300 people from the U.S. and Korea found that thinking in a second language reduced deep-seated, misleading biases that unduly influence how risks and benefits are perceived."

Our brains are developed with two distinct groups, the left and right hemispheres, that think in two very different manners. The left brain processes information rationally, sequentially, and logically and uses language, while the right hemisphere processes information randomly and holistically, and uses visuals more. We as humans have a dominant side of the brain which we prefer to use, and by catering to this dominant side (e.g. learning through listening for the left side, and learning through visuals for the right), we are able to learn more and understand more easily. We are not able to survive by only using one side of our brain, and it is necessary to use both and train both.

Developmentally, teens are at particular risk for reckless online behavior, including secrecy regarding social networking. Many people - adults and kids alike - view likes, loves, comments and followers as a barometer for popularity, even within a smaller, closed group. Teens can quickly get caught up in the feedback loop, posting and sharing images and videos that they believe will gain the largest reaction. Over time, teens' own values may become convoluted within an online world of instantaneous feedback, and their behavior online can become based on their "all about the likes" values rather than their real-life values. There is a very real biological basis for this behavior. The combination of social media pressure and an underdeveloped prefrontal cortex, the region of the brain that helps us rationalize decisions, control impulsivity and make judgments, can contribute to offensive online posts. In a recent study, researchers at the University of California, Los Angeles, found that the areas of teens' brains focused on reward processing and social cognition are similarly activated when they think about money and sex - and when they view a photo receiving lots of likes on social media. When teens viewed photos deemed risky, researchers found the brain regions focused on cognitive control were not activated as much, suggesting that it could be harder for them to make good decisions when viewing images or videos that are graphic in nature.

Suppose you hear someone say, "The man gave the ice cream the child." Does that sentence seem plausible? Or do you assume it is missing a word? Such as: "The man gave the ice cream to the child." People use an array of strategies to make sense of confusing statements. This article reveals the different strategies brains use to create a correct sentence based on semantic expectations.

"Change has occurred so rapidly for our species that now we are equipped with brains that are super sensitive to threat but also super capable of planning, thinking, forecasting and looking ahead," said Ahmad Hariri, a professor of psychology and neuroscience at Duke University. "So we essentially drive ourselves nuts worrying about things because we have too much time and don't have many real threats on our survival, so fear gets expressed in these really strange, maladaptive ways." Dr. Hariri studies the amygdala, an almond-shaped structure that has been called the seat of fear (there's one in each hemisphere of the brain). But it's really the seat of anticipation. The amygdala primes you to react - your pulse quickens, your muscles tense and your pupils dilate - even before other parts of your brain can figure out if you need to be scared or not. Nowadays, our amydalas can be overactive, thanks to 24/7 awareness of disasters around the world and/or stress/instability in one's personal and professional life. Remaining in this state of wary hypervigilance can contribute to issues like social anxiety, hypochondria, post-traumatic stress disorder, insomnia and all manner of phobias. It also plays a role in racial and religious intolerance because fearful people are more inclined to cling to the familiar and denigrate the unfamiliar. If you can sense and appreciate your fear - be it of flying, illness or social rejection - as merely your amygdala's request for more information rather than a signal of impending doom, then you are on your way to calming down and engaging more conscious, logic-dominated parts of your brain. At that point, you can assess the rationality of your fear and take steps to deal with it.

This article explains the "foreign language effect". It says that speaking a second language improves rational decision making and open-mindedness. It also discusses impacts of speaking a second language on our memory and elements of our personality.
