Loan words sometimes take on whole new meanings: for example the word ‘parka’ in Japan refers to a ‘hooded sweatshirt’ or ‘hoodie’ as opposed to the jacket commonly called a ‘parka’ in English:

parka

I’d be really curious to dig into the etymology of these kinds of words, and it’s probably fairly easy to trace their emergence because they came into use so recently. Perhaps parka entered Japanese not from english but from another language where the term already had this different meaning? Or, perhaps it was originally used as a brandname for a hooded sweatshirt?

Or, perhaps it’s illustrative of the nature of loan words themselves, where their lack of history makes them especially malleable and prone to mistaken meanings shortly after they’re introduced.

Regardless, here is a list of ‘loan words gone wrong,’ which sound as if they’ve come from english, but who’s meaning may not be immediately apparent to english-speakers, and words that sound like loan words but are in fact neologisms:

  • Paper driver – Peipaa doraibaa – ペーパー ドライバー – someone who has their driver’s license but doesn’t actually drive or know how to drive well.

The strong and simultaneous activation of both branches the autonomic nervous system, sympathetic and parasympathetic, is known as ‘autonomic conflict.’ In the cartoonish intro-biology view of the body, the sympathetic system fight or flight is an accelerator, the parasympathetic is pumping the breaks. (I always used to think parasympathetic = paramedics = ’rest and recover’.)

So you might think, that these effects would just cancel each other out, but slamming on the accelerator and breaks in the car at the same time, isn’t the same as letting your car cruise.

The specific effects of activating the sympathetic and parasympathetic nervous systems depend on the tissue, and the why is really gonna come down to the details, but let’s look at a couple examples first.

  1. Blood vessels are going to constrict. Because most blood vessels in the body receive sympathetic but not parasympathetic innervation. They’ve got an accelerator but no breaks.
  2. The heart. Alone, the sympathetic nervous system makes the heart beat faster and stronger. The parasympathetic nervous system while slow it’s rate and slightly decrease the strength of it’s contractions. But if you have high levels of both, things can get tricky: Paton et al. (2005) shows this can cause generate cardiac arrhythmias which have even rarely lead to sudden death in animals. This can also be studied in isolated hearts, shown in this figure:

a. Shows an isolated heart receiving adrenergic neurotransmitters. B-F different strange patterns of activity (arrhythmias) observed after adding parasympathetic neurotransmitters on top of sympathetic. From Shattock and Tipton, 2012.

Why is this? We have to look at what the sympathetic and parasympathetic nervous system are doing mechanistically. The parasympathetic post-ganglionic neurons (that are signaling to effector tissues) release acetylcholine. That acetylcholine can signal nicotinic and change ion concentrations, or stimulate muscarinic receptors and set of G-couple protein receptor cascades. Meanwhile, sympathetic is mostly adrenergic, though some tissues such as sweat glands are also activated using acetylcholine.

How those neurotransmitters affect the effector tissues on the specific receptors are on the effector tissues, and how the downstream pathways of those receptors interact. And because receptors activation is influenced by the concentration of neurotransmitter, ‘low equal’ levels of sympathetic and parasympathetic activation may not be the same as ‘high levels’ of parasympathetic activation.

This autonomic conflict occurs physiologically for example when you jump into cold water, which can activate both the ‘cold shock response’ and the ‘diving response’. An interesting article I found explores whether or not this response can generate the above-mentioned arrhythmias in people and may cause sudden cardiac arrest and death in vulnerable individuals (and which may be the true cause of deaths which are currently labeled as deaths due drowning or hypothermia).


One nuance of language that I hadn’t considered before spending a year in Japan is how words for expressing categories sometimes don’t quite line up. For example, in Japanese ‘juusu’ or juice refers not just to fruit and vegetable juices, but also soft-drinks. But what’s more, the line between fruits and vegetables itself is different, and, yes, melons are considered vegetables in Japanese.

To listen to a discussion about this, skip to minute 23:40.

In English the line is blurry (is a tomato a fruit)? And there are different definitions used commonly in ordinary language, by botanists, and even the supreme court. And while we’re here, is corn a vegetable or a grain? You can imagine that it must be quite confusing to learn the borders between these words. Somehow these objects and concepts are sorted and clustered based on various characteristics: are they sweet, are they seed-bearing, how closely do they resemble some prototypical fruit…

Colors in American English and Japanese

But, what is considered a cluster, and where the lines are drawn varies from language to language. Another classic example of this is colors. Colors lie on a spectrum of infinite minute variations, but linguistically we chop them up: yellow, green, blue, purple. But exactly where these lines are drawn, and how many basic categories there are varies between languages. For example, midori or green is a relatively late linguistic addition to Japanese and to this day fresh vegetables and traffic lights are describe as aoi which now means blue, but used to–and in these contexts, it still does–describe a set of clusters that encompassed both blue and green.

Clusters of ‘chromatic color categories in color space’ Kuriki et al., 2017

And while it’s easy to say, ‘wow, that’s so strange,’ are you bothered by the fact that we don’t really have a commonly used word for sky blue/light blue/cyan ? According to Kuriki et al., 2017, this color is now often described using the word ‘mizu’ (full text article) which literally means water. And here, I’d like to switch gears and dig into this study.

What are the Best Introductory Psychology textbooks, and are they telling us the truth? I looked up the Psychology textbooks used at the top programs across the US and talked to Professor Chris Ferguson, author of Education or Indoctrination? The Accuracy of Introductory Psychology Textbooks in Covering Controversial Topics and Urban Legends About Psychology, about his recommendations for the most accurate textbooks.

When Chris Ferguson, a professor at Stetson University, was trying to choose a textbook for his introductory psychology course, he realized his own field of study, videogame violence was being mis-portrayed in some textbooks:

“It’s an area that’s really controversial and the data isn’t consistent or clear, but at least some textbooks seemed to be trying to report it as if the research was more clear than it actually was.”

It intrigued Ferguson, so he decided to research it systematically and publish a paper on errors in textbooks. Errors went beyond over-simplifications that glossed over controversies in the field and murky data, sometimes text books including examples that were flat out wrong:

As an intern at Gimlet Media’s Science Vs, I’ve learned a lot about making podcasts. The process of making a podcast can seem mysterious, if not impossible. And when it comes to tasks like finding the overall structuring of a story or selecting the very best audio from three-hour-long interviews, if you’re like me, you may be unsure where to even begin.

I have good news, it’s not magic, there is a method. Radio producers have been been making shows under the constraint of the hardest of deadlines (dead air, gasp!), so skilled producers have systematized the process of creating audio and written how-to guides, one even in comic book form! (And while learning that some of my co-workers had been immortalized in a graphic novel was probably not the best for my already shy interactions with them, I learned a ton from that book!)

Anyways, here’s my unofficial Gimlet reading lists: one of books the Gimlet office keeps on hand for newbies like me and then a second of books on nonfiction writing and journalism that Gimlet colleagues recommended to me. 

Books about audio storytelling / Books about making podcasts and radio stories:

  1. Out one the Wire: The Storytelling Secrets of the New Masters of Radio by Jessica Abel (with a foreword by Ira Glass)
    out on the wire cover
    Comic-book writer and illustrator Jessica Abel extends and updates her classic, Radio an Illustrated Guide, interviewing the hosts and staff that create the hits This American Life, The Moth, Radiolab, Planet Money, Snap Judgement, Serial, Invisibilia, and other narrative radio shows. This book starts from the very beginning, and teaches you every step of the process of creating a story from start to finish, what sorts of big picture questions and details producers think about, and all of the weird jargon like ‘bounces,’ ‘logging,’ and ‘selects.’ And abel shows as well as telling–using the same techniques that are described in this book to make it feel more like a narrative than a dry how-to guide. Plus, it’s funny, cheap, and you’ll learn a bit about the idiosyncratic personalities who create the shows you love.
  2. Sound Reporting: the NPR guide to audio Journalism and Production – by Jonathon Kern
    sound reporting
    What Out on the Wire does for Gimlet-style narrative stories, Sound Reporting does for more tradional NPR journalism. (Though, unfortunately, more traditional also means no pictures.) However, Sound Reporting is an audio journalism textbook written in clear conversational language by the Executive Producer for Training at NPR, and as such explains every step of making an audio news story. Not only reporting, producing, and editing, but also the ethical considerations of journalism–including examples of journalism gone terribly wrong! (For example, did you know some journalists erred and published in the 1980s that 2 million children were abducted each year, probably contributing to the long-lasting ‘stranger danger’ that still worries people today?) Sound Reporting is full of interesting, concrete examples like this, that illustrate Kern’s points and make it easy to read and understand.
  3. Reality Radio: Telling True Stories in Sound – Edited by John Biewen and Alexa Dilworth
    reality radio
    Reality Radio is a collection of 24 essays. The second edition is hot of the press (Feb., 2017) and includes up to date information about the rapidly changing world of radio: the ascendance of the podcast; greater cultural, racial, and topical variety; and the changing economics of radio itself.

    Contributors include many of the familiar faces from Out on the Wire, and a wider group including radio-makers from Canada, the United Kingdom, and Australia. The contributers are: Jad Abumrad, Daniel Alarcon, Jay Allison, damali ayo, John Biewen, Emily Botein, Chris Brookes, Scott Carrier, Katie Davis, Sherre DeLys, Ira Glass, Alan Hall, Dave Isay, Natalie Kestecher, Starlee Kine, The Kitchen Sisters, Sarah Koenig and Julie Snyder, Maria Martin, Karen Michel, Joe Richman, Dmae Roberts, Stephen Smith, Alix Spiegel, Sandy Tolan, and Glynn Washington.

Books about nonfiction writing and journalism more broadly:

  1. Follow the story : How to Write Successful Nonfiction – by James B Stewart
    follow the story
    I took the fact that Follow the Story’s Amazon page recommends it alongside my favorite style guide Zinsser’s On Writing Well as a very good omen. Stewart is a former editor of the Wall Street Journal’s front page, and draws heavily on examples from his own writing. This may irk some, but hey, write what you know, right? As much as this is a step-by-step guide for researching and writing a story, it is a philosophy about how to following your curiosity, and then leading the reader/listener down that same journey.
    I’m looking over the amazon reviews for this book and I don’t get them:
    Read this book if you want to be a journalist,” says Jen. Four Stars. I would have sworn a 5-star rating was coming after that unequivocal endorsement.
  2. Naked in Baghdad: The Iraq War and the Aftermath as Seen by NPR’s Correspondent Anne Garrels
    naked in baghdad
    A lot of times in radio and journalism there is no script–no one can tell you what you should be doing and that can be terrifying, and that’s without putting your life in danger. Naked in Baghdad is an example, of a journalist rising above the call of duty, who “as one of only sixteen non-embedded journalists who stayed in the now legendary Palestine Hotel throughout the American invasion she managed to deliver the most immediate, insightful and independent reports with unparalleled vividness and immediacy,” and the madness of Iraq are juxtaposed against  e-mails from her husband.
    Naked in Baghdad is an inspiring piece of work that illustrates the types of dramatic and impactful work you can do if you learn the skills of creating radio. As Ron Franscell points out in an Amazon Review, audio journalists can get access where others can’t: “She had no cameras… no bulky notebooks to mark her as a reporter in a crowd. Only a tape recorder the size of a cigarette pack … and the sounds of war. She traveled lightly and discreetly, just under the radar of the gatekeepers.”

So there’s the start of a reading list for the aspiring radio journalist, podcaster, or audio storyteller. What books have helped or inspired you that I’m missing from the list? Leave them in a comment below or tweet me @neuroamer. And let me know if you have other questions about making podcasts or working at Gimlet.


Learning a new language can seem impossible, especially later in life, but it’s not–in fact, language learning is something our brains specially evolved to do! In this post I’ll share why why language learning is fascinating from a neuroscience perspective, my experience learning Japanese from scratch at twenty-eight, and end with three tricks for self-study that I learned along the way.

Language is a miracle, where neurons signal between brains by vibrating throat flaps

Just imitating a word is amazing. Think about it, we hear a word and then somehow figure out how to vibrate flaps in our throat to produce the exact same sound–what?! And that word spans a wide space of sounds–it can be said at different pitches, with different intonations and accents–yet we can hear that word through the roar of a crowded cocktail party. But speech recognition and imitation are just the beginning–we learn to impute the meaning of so many other words, just be hearing them or seeing them in context, and then using grammar can combinatorially recombine words into an infinite number of sentences, which can by understood by the listener even if they have never been uttered before in history.

Part of why language feels so miraculous, is because it is a human super-power. While animals like songbirds have the vocal imitation part down, and we can teach commands to dogs and rudimentary sign language to apes, we seem to be the only species specially wired to learn language, particularly when we’re young. I regret that I didn’t take advantage of free language classes when I was younger, but as cliche as it sounds, it’s never too late. Let me introduce you to Sally.

First off, if you’re experiencing the worst headache of your life, please stop reading and head to an emergency room, especially if it’s onset was sudden.
Alright, moving on:

I’ll start with a personal story and get to the studies, below. Feel free to skip ahead.

I was thirteen, in English class and struggling to read. Don’t get me wrong, I knew how to read, but on this particular day, in this particular class, I couldn’t read at all. The center of my vision looked something like this:

migraine

“I’m going blind,” I thought, as I strained to read the blurred letters. I’m going fucking blind. I was too embarrassed to raise my hand and ask to go to the nurse. What exactly would I say, if I did? That I’m going blind? I decided to wait it out. Always a smart to wait things out when you’re convinced you’re becoming permanently disabled, right? So, I sat waiting until the end of the period, hoping I wouldn’t get called on to read something.

When the period ended, I bee-lined it for the nurse’s office. On the way, my head began to throb.

“I’m going blind” I told her, expecting her face to fill with worry.

Lab Wars Interview

To subscribe to Neuroamer audio content in podcast form, click here.

This is an unusual post for the blog because it’s primarily an audio interview  with charming Caezar Al-Jassar, Ph.D, co-creator of the game Lab Wars. The conversation goes into having a side project as a young academic and Caezar’s kickstarter success, but also touches on heavier topics such as the difficulties of imposter syndrome, and leaving the academic bubble and trying to make it in the real world. I haven’t gotten a chance to play Lab Wars yet, but it’s gotten good initial reviews on Board Game Geek.

Following are links to the games we discussed, and some musings on why board games are fun, why boardgames appeal to nerds, and whether playing games can make you smarter.

Other games we discussed in the interview audio (which might make a great gift for a nerd you love this holiday season, hint hint, Mom). [Mom, if you actually read this that was just a joke]

Do you drink a glass of water before going to bed? Then, hate to break it to you, but you have something in common with a mouse.

Overview

A new paper suggests that a mouse’s biological clock increases its thirst shortly before it sleeps.1 Why? The study’s authors suggest this increased drive to drink, allows a mouse to drink a little bit of extra water, which will help maintain the mouse’s balance of water and salt throughout the night as it loses fluid through for example through sweat.

The study shows the mouse’s brain is hard-wired to anticipate fluid will be lost throughout the night. The part of the brain that keeps track of the biological clock, the SCN, sends a connection that signals to the part of the brain that regulates thirst, the OVLT,2 and this connection releases Vasopressin as a neurotransmitter.

slice
Brain Slices: Scientists anesthetize the mouse and remove it’s brain keeping it in an oxygenated fluid with nutrients, so the cells stay alive. In this case, they cut the brain at a 34 degree angle to obtain a slice that contains the OVLT, SNC, and connection between them.

Fast Food – Fast News

Trump is really, really smart. His intellect is huge and he knows things. Many such things. Excellent man.

One thing he knows: Our schools are really, really bad. Really, really, really bad. They’re nasty places.

And maybe because of that, he uses plain language.

Shaming or blaming people for being stupid–for being uninformed, for not caring about politics–is stupid. It’s like blaming people for being fat.

Generations of individuals didn’t become lazy gluttons at the exact same time because they were weak. No, our world changed. McDonalds everywhere, temptations everywhere. It was bad. Bad, bad food all around us.    Continue reading ‘Using Plain Language to Make America Great Again’
