"Teenagers are more susceptible to developing disorders like addiction and depression ... "The brain region traditionally associated with reward and motivation, called the nucleus accumbens, was activated similarly in adults and adolescents," said Moghaddam. "But the unique sensitivity of adolescent DS to reward anticipation indicates that, in this age group, reward can tap directly into a brain region that is critical for learning and habit formation." ... not only is reward expectancy processed differently in an adolescent brain, but also it can affect brain regions directly responsible for decision-making and action selection. ... "Adolescence is a time when the symptoms of most mental illnesses-such as schizophrenia and bipolar and eating disorders-are first manifested, so we believe that this is a critical period for preventing these illnesses," Moghaddam said."

A recent study was conducted with 48 adults who were asked to perform a finger exercise as fast as they can. Some participants were given compliments after the task. The researchers concluded that, "To the brain, receiving a compliment is as much a social reward as being rewarded money." They have found scientific proof that people perform better after receiving a social reward such as a compliment.

Emotional contagion is the phenomenon of "catching" other people's emotions and moods. According to Elaine Hatfield, a psychology professor at the University of Hawaii, humans are hard-wired "to automatically mimic and synchronize facial expressions, vocalizations, postures, and movements with those of another person and, consequently, to converge emotionally." Primitive emotional contagion is a basic building block of human interaction. It helps us coordinate and synchronize with others, empathize with them, and read their minds-all critical survival skills. When we mimic, the body gets feedback about the expressions we've taken on; we then feel what the other person is feeling. Gary Slutkin, a physician, epidemiologist, and founder and CEO of the nonprofit Cure Violence, says that emotional contagion, specifically anger and violence, springs from four mechanisms involving the brain: 1. Engagement of the cortical pathways for copying, a behavior related to mimicry. The most contagious behaviors are the most emotionally engaging, as well as the ones carried out by the people who are most relevant to you. 2. Activation of the brain's dopamine system, which works in anticipation of a reward. "Activation of that system puts you down a pathway toward what is important socially and for survival," he says. If you anticipate being rewarded for responding to someone with anger or violence, you are more likely to get on that behavioral track. 3. The brain's pain centers activate from veering off or being shut out from getting a reward. "A sense of I can't stand it lights up in the context of disapproval." 4. Serious injuries or abuse cause the limbic system and amygdala in the lower brain to become hyperreactive. "This causes you to be less in control, which accelerates violent behavior," Slutkin says. It also makes you more likely to get angry and be quick to react. "Then there's hostile attribution, another part of what happens with the limbic sy

Our brains are set up to do two things at once, but not three, a French team reports in the journal Science. Their experiment examined an area of the brain involved in goals and rewards and tested people's abilities to accomplish up to three mental tasks at the same time. When volunteers were doing just one task, there was activity in goal-oriented areas of both frontal lobes, suggesting that the two sides of the brain were working together to get the job done. But when people took on a second task, the lobes divided their responsibilities. Since the brain has only two frontal lobes, researchers surmised there might be a limit to the number of goals and rewards it can handle. Indeed, when people started a third task, one of the original goals disappeared from their brains. Also people slowed down and made many more mistakes.

The human voice appears to trigger pleasure circuits in the brains of typical kids, but not children with autism, a Stanford University team reports. The finding could explain why many children with autism seem indifferent to spoken words. The Stanford team used functional MRI to compare the brains of 20 children who had autism spectrum disorders and 19 typical kids. In typical kids there was a strong connection between areas that respond to the human voice and areas that release the feel-good chemical dopamine, but that connection was reduced in autistic children. Connections between voice areas and areas involved in emotion-related learning also were weaker, creating greater communication difficulties. The new study's suggestion that motivation is the problem could explain why speech often comes late to children with autism even though the brain circuit involved in processing spoken words seems to function normally; the reward circuitry isn't working the way it does in typical children.

Keeping in touch is no longer about face to face, but instead screen to screen, highlighted by the fact that more than 1 billion people are using Facebook every day. Social media has become second nature -- but what impact is this having on our brain? "In a recent study, researchers at the UCLA brain mapping center used an fMRI scanner to image the brains of 32 teenagers as they used a bespoke social media app resembling Instagram. By watching the activity inside different regions of the brain as the teens used the app, the team found certain regions became activated by "likes", with the brain's reward center becoming especially active." This article goes into depth on how social media like instagram is changing our brain. It shows us what parts of our brain are getting stimulated when we use social media! It also talks about peer influence, social learning, and reward circuitry.

The brains of adolescents are notoriously more receptive to short-term rewards and peer approval, which can lead to risky behavior. But researchers and educators are noticing that young people are also more sensitive to notions of social justice and autonomy. Teenage rebellion can be virtuous - even wholesome - depending on the situation. A new study in the Proceedings of the National Academy of Sciences finds that teenagers make wiser choices if they are encouraged to reimagine healthy behavior as an act of defiance.

Like a human's brain, a dog's brain responds to the meaning of a word and how the word is said. And like with a human's brain, the dog's left hemisphere reacts to meaning and the right hemisphere reacts to intonation. In the study, words were said to dogs in positive and neutral tones, but only positive words spoken in a positive tone prompted strong activity in the brain's reward center. This study suggested that non-primates could process meaning and emotion long before humans could talk.

Studies suggest a link between negative cognition (a.k.a. negative thinking) and increased propensity for guilt, chronic anxiety clinical depression. (Apparently, women are more prone to negative cognition than men.) Psychology professor Emeritus Tom Stevens of California State University describes some common negative thinking pitfalls and offers advice as to what you can do instead. Research has supported the efficacy of cognitive therapy (called cognitive restructuring) that replaces these styles with more positive thinking. 1. Negative bias. Negative bias is a tendency to look at the more negative side of some event, person, object, or situation. It gives a negative interpretation or a negative point of view for looking at a situation. Instead think: I will assume the best instead of assume the worst. Positive self-fulfilling prophesies tend to create positive outcomes; negative self-fulfilling prophesies tend to create negative outcomes. Negative explanations of my own or other peoples' underlying motives cause me to intensify my anger or other negative feelings. Assuming the world is a hostile place creates fear, anxiety, and anger. 2. Negative selective abstraction. Selective abstraction means taking negative features of a situation out of context and exaggerating their significance. Usually it also means negating positive features. Example: A student who gets four "A"s and one "C," then focuses on the "C's." Instead think: I will list at least one positive feature for each negative feature. I will limit my focus on negative features to constructive thoughts about how I can either accept or change the negative features. 3. Overgeneralization. When we overgeneralize, we assume far-reaching conclusions from limited data. A student made a "D" on one test. She overgeneralizes, she doesn't just think "Well, I messed up on that one test. Instead, "I may not pass the course, not ever finish college." "I must be stupid and a failure." "My whole life is ruin

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.

Food for thought: " A few weeks ago, the world on my phone seemed more compelling than the offline world - more colorful, faster-moving and with a bigger scope of rewards. I still love that world, and probably always will. But now, the physical world excites me, too - the one that has room for boredom, idle hands and space for thinking. I no longer feel phantom buzzes in my pocket or have dreams about checking my Twitter replies. I look people in the eye and listen when they talk. I ride the elevator empty-handed. And when I get sucked into my phone, I notice and self-correct. It's not a full recovery, and I'll have to stay vigilant. But for the first time in a long time, I'm starting to feel like a human again."

This study examines how bilingualism affects the wages of Asian and Hispanic workers using 2000 Census data. In contradiction to the general belief that bilingualism can provide a competitive advantage in the labor market, we find no evidence that 1.5-generation and U.S.-born Asian and Hispanic bilingual workers generally have higher wages than their English monolingual co-ethnics; in some cases, in fact, their wages are significantly lower. In search of specific circumstances under which bilingualism might provide an economic advantage, we also examine interactions of language with such variables as education, employment in the public rather than the private sector, and the size of the population of mother-tongue speakers. With limited exceptions, we find no sign of greater economic returns to bilingualism. Since bilingualism requires considerable effort to maintain across generations in the United States, we conclude that the virtual absence of economic rewards for it creates pressure for linguistic assimilation.

Metaphors are extremely useful things. They provide a common language-an agreed-upon shorthand-for truths that can be difficult to discuss in terms that are simultaneously broad and precise. It doesn't take a Lakoff or a Luntz to appreciate the power of shared metonyms, particularly as the country grapples with the results of an election that was a political embodiment of that well-worn Fitzgerald line: "The test of a first-rate intelligence is the ability to hold two opposed ideas in the mind at the same time, and still retain the ability to function." This election, in particular, featured many more than two oppositional ideas. The 2018 midterms were about voter suppression, which is also to say about robbing swaths of Americans of their constitutional rights, which is also to say about structuralized inequality. They were about enfranchisement and its opposite. They were about progress. They were about backlash. They were about women winning. They were about women losing. They were about compassion empowered, and racism rewarded, and hard work realized, and cruelty weaponized, and corruption unpunished. They were about hatred. They were about love. They were about history made. They were about history ignored. They were about American exceptionalism in the best sense and-at the same time-in the worst. How do you sum that up in a headline or a news article? How do you talk about it in neatly cable-newsed sound bites? The true answer is that you can't, and the even truer answer is that this is why it is necessary to have a flourishing and extremely diverse media ecosystem, so that a broadly coherent picture might emerge from the individual efforts-but the more practical and immediate answer is that you can try to use metaphors to summarize the situation. You can talk about waves, with their familiarity and their liquidity and their visual power, and you can talk about the color of your notional water, and the size and shape of the swell, and you

Reinforcing good behavior while discouraging disobedience and anti-social behavior generally produces positive results in children. Positive reinforcement helps children feel good about their choices, which motivates them to increase the behaviors that bring rewards. Praise and positive reinforcement usually produces both short-term and long-term positive results. This article talks about how positive reinforcement and encouragement from a young age affects the development of the character of a child.

An app called Duolingo is the top app to learn a new language. The site includes learning vocab and grammar and doing exercises that are tailored to what the person learns quickly and what the person need to repeatedly review. Teaching language has changed from early "grammar translation" (learning grammar rules and translating sentences) to "audiolingualism" (learn rules and patterns by repeating sentences over and over) after World War II to other methods in the 60s and 70s that turned into a general "communicative approach" which focuses on the function of language as communication not the rules and structure. The app is mostly "audiolingual" because it drills users to repeat words and phrases over and over, but it also helps users learn a lot of words, reminds them to practice, and keeps them practicing with virtual rewards so can be effective.

Abstract: Self-affirmation theory posits that people are motivated to maintain a positive self-view and that threats to perceived self-competence are met with resistance. When threatened, self-affirmations can restore self-competence by allowing individuals to reflect on sources of self-worth, such as core values. Many questions exist, however, about the underlying mechanisms associated with self-affirmation. We examined the neural mechanisms of self-affirmation with a task developed for use in a functional magnetic resonance imaging environment. Results of a region of interest analysis demonstrated that participants who were affirmed (compared with unaffirmed participants) showed increased activity in key regions of the brain's self-processing (medial prefrontal cortex + posterior cingulate cortex) and valuation (ventral striatum + ventral medial prefrontal cortex) systems when reflecting on future-oriented core values (compared with everyday activities). Furthermore, this neural activity went on to predict changes in sedentary behavior consistent with successful affirmation in response to a separate physical activity intervention. These results highlight neural processes associated with successful self-affirmation, and further suggest that key pathways may be amplified in conjunction with prospection.
