Radical Theory Overturns Old Model of How Emotions are Made
In her new book, professor of psychology Lisa Feldman Barrett proposes a radical new theory of emotions.
The classic model of emotion goes something like: You're born with an innate suite of emotions – happiness, sadness, anger, fear. You feel these emotions by perceiving a stimulus. That triggers a circuit in your brain. That then causes a bodily response, which causes you to behave a certain way.
Emotions happen to you, essentially.
That’s all wrong, says Lisa Feldman Barrett, an author and psychology professor at Northeastern University. In her latest book, "How Emotions Are Made," Barrett synthesizes research from neuroscience, biology and anthropology to construct a radical new theory of emotion.
According to Barrett, emotions aren’t reactions to the world. Rather, emotions actually construct our world. And it happens because of interoception.
Interoception is our sense of the physiological condition of our bodies. This sense monitors our internal processes and sends status updates to the brain. Those updates come in four rudimentary signals: pleasantness, unpleasantness, arousal and calmness. Emotions, Barrett claims, are formed from the brain's attempt to make sense out of this raw data. The brain does this by taking the raw data and filtering it through our past experiences – through our learned concepts.
(From a study that asked participants to interpret emotions by viewing facial expressions.)
This means emotions aren't objective reflections about events in the world. Barrett elaborated in a recent episode of NPR's Invisibilia podcast:
“For every emotion category that we have in the U.S. that we think is biologically basic and universal, there's at least one culture in the world that doesn't really possess a concept for that emotion and where people don't really feel that emotion.”
The same concept applies to vision, Barrett suggests, noting cases in which blind people who've had corneal damage since birth remained blind for some time after receiving transplants.
“They don't see for days and sometimes weeks. And sometimes years there are things they can't see because they don't have concepts. Their brain has no past visual experience to make meaning of the visual sensations that they receive.
...We would imagine from the classical view that they would just be able to see everything, but they don't.”
The key implication of Barrett's theory is both striking and somewhat liberating: We have a lot more control and responsibility over our emotions than previously thought. The concepts we've accrued, whether consciously or not, can be learned and unlearned. According to the theory, you have the power to fundamentally change your experience of emotion.
Barrett's theory has a catch, though. If Barrett is correct, then what should society tell those suffering from, say, PTSD? To sit down and learn some new concepts? Barrett said:
“I see the risk in what I'm saying – right? – but science is science. And we have to - I feel like it's necessary to draw people's attention to what the science has to say. And in the proper context in society, in culture, people can debate the consequences. But I think, you know, I do think that it's very dangerous to treat things as objective when they're not.”

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
The 'People Map of the United States' zooms in on America's obsession with celebrity
- Replace city names with those of their most famous residents
- And you get a peculiar map of America's obsession with celebrity
- If you seek fame, become an actor, musician or athlete rather than a politician, entrepreneur or scientist
Chicagoland is Obamaland

Chicagoland's celebrity constellation: dominated by Barack, but with plenty of room for the Belushis, Brandos and Capones of this world.
Seen from among the satellites, this map of the United States is populated by a remarkably diverse bunch of athletes, entertainers, entrepreneurs and other persons of repute (and disrepute).
The multitalented Dwayne Johnson, boxing legend Muhammad Ali and Apple co-founder Steve Jobs dominate the West Coast. Right down the middle, we find actors Chris Pratt and Jason Momoa, singer Elvis Presley and basketball player Shaquille O'Neal. The East Coast crew include wrestler John Cena, whistle-blower Edward Snowden, mass murderer Ted Bundy… and Dwayne Johnson, again.
The Rock pops up in both Hayward, CA and Southwest Ranches, FL, but he's not the only one to appear twice on the map. Wild West legend Wyatt Earp makes an appearance in both Deadwood, SD and Dodge City, KS.
How is that? This 'People's Map of the United States' replaces the names of cities with those of "their most Wikipedia'ed resident: people born in, lived in, or connected to a place."
‘Cincinnati, Birthplace of Charles Manson'

Keys to the city, or lock 'em up and throw away the key? A city's most famous sons and daughters of a city aren't always the most favoured ones.
That definition allows people to appear in more than one locality. Dwayne Johnson was born in Hayward, has one of his houses in Southwest Ranches, and is famous enough to be the 'most Wikipedia'ed resident' for both localities.
Wyatt Earp was born in Monmouth, IL, but his reputation is closely associated with both Deadwood and Dodge City – although he's most famous for the Gunfight at the O.K. Corral, which took place in Tombstone, AZ. And yes, if you zoom in on that town in southern Arizona, there's Mr Earp again.
The data for this map was collected via the Wikipedia API (application programming interface) from the English-language Wikipedia for the period from July 2015 to May 2019.
The thousands of 'Notable People' sections in Wikipedia entries for cities and other places in the U.S. were scrubbed for the person with the most pageviews. No distinction was made between places of birth, residence or death. As the developers note, "people can 'be from' multiple places".
Pageviews are an impartial indicator of interest – it doesn't matter whether your claim to fame is horrific or honorific. As a result, this map provides a non-judgmental overview of America's obsession with celebrity.
Royals and (other) mortals

There's also a UK version of the People Map – filled with last names like Neeson, Sheeran, Darwin and Churchill – and a few first names of monarchs.
Celebrity, it is often argued, is our age's version of the Greek pantheon, populated by dozens of major gods and thousands of minor ones, each an example of behaviours to emulate or avoid. This constellation of stars, famous and infamous, is more than a map of names. It's a window into America's soul.
But don't let that put you off. Zooming in on the map is entertaining enough: celebrities floating around in the ether are suddenly tied down to a pedestrian level, and to real geography. And it's fun to see the famous and the infamous rub shoulders, as it were.
Barack Obama owns Chicago, but the suburbs to the west of the city are dotted with a panoply of personalities, ranging from the criminal (Al Capone, Cicero) and the musical (John Prine, Maywood) to figures literary (Jonathan Franzen, Western Springs) and painterly (Ivan Albright, Warrenville), actorial (Harrison Ford, Park Ridge) and political (Eugene V. Debs, Elmhurst).
Freaks and angels
The People Map of the U.S. was inspired by the U.S.A. Song Map, substituting song titles for place names.
It would be interesting to compare 'the most Wikipedia'ed' sons and daughters of America's cities with the ones advertised at the city limits. When you're entering Aberdeen, WA, a sign invites you to 'come as you are', in homage to its most famous son, Kurt Cobain. It's a safe bet that Indian Hill, OH will make sure you know Neil Armstrong, first man on the moon, was one of theirs. But it's highly unlikely that Cincinnati, a bit further south, will make any noise about Charles Manson, local boy done bad.
Inevitably, the map also reveals some bitterly ironic neighbours, such as Ishi, the last of the Yahi tribe, captured near Oroville, CA. He died in 1916 as "the last wild Indian in North America". The most 'pageviewed' resident of nearby Colusa, CA is Byron de la Beckwith, Jr., the white supremacist convicted for the murder of Civil Rights activist Medgar Evers.
As a sampling of America's interests, this map teaches that those aiming for fame would do better to become actors, musicians or athletes rather than politicians, entrepreneurs or scientists. But also that celebrity is not limited to the big city lights of LA or New York. Even in deepest Dakota or flattest Kansas, the footlights of fame will find you. Whether that's good or bad? The pageviews don't judge...
Average waiting time for hitchhikers in Ireland: Less than 30 minutes. In southern Spain: More than 90 minutes.
- A popular means of transportation from the 1920s to the 1980s, hitchhiking has since fallen in disrepute.
- However, as this map shows, thumbing a ride still occupies a thriving niche – if at great geographic variance.
- In some countries and areas, you'll be off the street in no time. In other places, it's much harder to thumb your way from A to B.
Technology may soon grant us immortality, in a sense. Here's how.
- Through the Connectome Project we may soon be able to map the pathways of the entire human brain, including memories, and create computer programs that evoke the person the digitization is stemmed from.
- We age because errors build up in our cells — mitochondria to be exact.
- With CRISPR technology we may soon be able to edit out errors that build up as we age, and extend the human lifespan.
