L’immenso potere dei “like” su una mente adolescente (The immense power of the “like” of a teenage mind)
La Stampa: L’influenza dei social network e, in generale delle nuove tecnologie, sulle nostre abitudini e sulla nostra mente è ormai da tempo sotto attento esame degli scienziati. Superata la fase delle argomentate opinioni e degli illustri commenti, grazie ai risultati delle ricerche, oggi possiamo avere un quadro sempre più dettagliato dei loro effetti sul nostro cervello. In uno studio apparso sulla rivista Psychological Science, i neuroscienziati dell’Università della California a Los Angeles UCLA hanno analizzato il funzionamento dei circuiti cerebrali di un adolescente mentre frequenta un social network, evento tutt’altro che saltuario.

For Teenagers, the Pleasure of ‘Likes’
The New York Times: Move over sex, drugs and rock ‘n’ roll. For today’s teenager, it’s all about the “likes.” A “like,” for the uninitiated, refers to the positive feedback given to a post on social media. And new research shows that likes appear to be somewhat intoxicating to teenagers. The same reward center in the brain that is involved in the sensation of pleasure and activated by thoughts of sex, money or ice cream also is turned on when teenagers see their photos getting a lot of likes on social media.

The sneaky ways babies get inside our heads
The Washington Post: Big eyes, bigger heads and squishy little noses. The physical characteristics that make babies so squeezable are called the Kindchenschema, and they keep parents all over the animal kingdom from leaving stinky infants to their own devices. But research suggests that this cuteness does more than just tell your lizard brain that the squirming screamer in your arms is important. "Cute" could actually be a complex, multi-sensory attack that babies have evolved to hijack your brain. Cute is a long-standing interest of Morten Kringelbach of Oxford University.

How “likes” affect teenagers’ brains
The Economist: FOR the first six months after teenagers in Colorado pass their driving test, the state bans them from carrying non-sibling teenage passengers unless someone over 21 is also in the car. It is not alone in this ageist approach. Fourteen other American states impose similar restrictions. The reason is that mountains of data show teenagers take risks more readily in the presence of their peers. But, in today’s virtually enabled world, “presence” is a slippery concept.

Financial Stress Hurts, Literally
Scientific American Mind: Few things feel worse than not knowing when your next paycheck is coming. Economic insecurity has been shown to have a whole host of negative effects, including low self-esteem and impaired cognitive functioning.

Unless You’re Oprah, ‘Be Yourself’ Is Terrible Advice.
The New York Times: IT was going to be the biggest presentation of my life — my first appearance on the TED Conference main stage — and I had already thrown out seven drafts. Searching for a new direction, I asked colleagues and friends for suggestions. “The most important thing,” the first one said, “is to be yourself.” The next six people I asked gave me the same tip. We are in the Age of Authenticity, where “be yourself” is the defining advice in life, love and career. Authenticity means erasing the gap between what you firmly believe inside and what you reveal to the outside world.
