So let’s talk about science. Science is awesome and important

and it holds a lot of social value. It influences everything from how we get around to how long and healthy our lives are.

程度の副詞

Even my being able to talk with you right now,

through the marvel of online video? You can thank science for that. But wait,

isn’t this a channel about linguistics? Well, you might never have thought of it this way,

but linguistics is a science too. I’m Moti Lieberman, and this is the Ling Space.

When you think about language and how people study it, science is probably not the first thing that comes to mind.

After all, you don’t really need to do science to it for it to be meaningful.

it ties into our culture, in our literature, our poetry and our music.

Just as we can appreciate a spectacular night sky without worrying about astronomy,

or a butterfly without thinking about how its wings work, we don’t need linguistics to appreciate

the way that people use language. We can just enjoy the style of a writer’s individual voice,

or the rhythmic flow of a well-turned set of syllables.

But the thing is, whether or not you realize it, the science is always there inside language!

It’s part our biological heritage, and we find a ton of things in common across every language of the world.

And it’s a really key social and cultural institution, too,

that can define communities and sell products and start wars.

But all the different parts of language work according to rules that we can describe,

and if we want to do that, science is how we make it happen.

We need the same tools of hypothesizing, experimenting, carefully judging,

and reworking that make up the backbone of science the world over.

Now, the case for linguistics as a science is maybe at its strongest when you look at something like neurolinguistic testing.

If you’re sticking someone in an fMRI machine

or an electrode cap, and you’re measuring their brain activity, that just screams “science is happening!”

And we’ve learned a ton about the human brain and how it does

its crazy language thing by using those kinds of techniques.

We can say the same thing about psycholinguistic research, too. There’s a lot we can observe

about people’s behaviour and how it interacts with language.

We can measure how people look around a visual space when they listen to a sentence,

or where their attention goes first when they hear something ambiguous.

We can learn what kinds of sentences are easier or harder for people to construct

by looking at how quickly they interpret them, or by checking where in a complicated sentence they get hung up.

We can see how people’s systems of sound work

by playing them words that are mixed with background noise or static,

Some of the data from psycholinguistic research is pretty amazing.

So like, one of my favourite discoveries is how people can just ignore

errors or missing data and make sense of what they’re hearing or reading anyway.

The power of native speakers to overcome probems is so huge that even when we just cut out

sounds from words completely, on purpose, they  have no trouble filling in the blanks.

A lot of the time, they don’t even realize that anything was missing!

How many of you noticed that there wasn’t an /l/ when I said “problems” earlier?

Did it stop you from understanding the rest of the sentence? If you’re a native English speaker,

chances are that even if you were eagle-eared enough to hear it, you just skimmed right on by without thinking about it.

And thanks to linguistic science, we have all the experimental data

So experiments actually underlie a lot of linguistics research. And our tools and techniques are pretty refined, too.

We’ve studied how super tiny infants react to language,

before they can even speak. We’ve isolated the exact kind of sentences

that people with aphasia have problems with, so we can figure out

precisely what language impairments are made of.

We can even get unbiased judgments from people about language without them realizing what we’re trying to do.

The number of techniques and methods for examining language is pretty huge,

and it keeps growing as we find new ways to

address the questions we’re interested in.

But linguistics isn’t all experiments, though. A lot of the work that gets done is theoretical,

with nary a lab in sight. The trees that we build in syntax or the rules that we describe in phonology

don’t really seem like science, right? Where’s the science when you’re just sitting there and thinking,

“Hmmm, this sentence is beautiful and perfect, and this other one is terrible garbage.

I’m going to explain why by proposing a rule to divide them!”

Well, the theories we come up with about how language works inform all the experiments that we do.

Compare it to something like physics. In both fields, phenomena happen all the time,

whether we’re studying it or not. Stuff speeds up when it falls,

and mouths move to make speech sounds. And when you research those phenomena,

you get a body of data about how the world works – either physical movements and forces,

or the positions and vibrations of your articulators.

Both physicists and linguists then apply the scientific method to that data:

with the sum of their understanding, they’ll propose a hypothesis that explains what they’ve observed.

They’ll make predictions based on that proposal, and then see whether those predictions are met,

based on further analysis and experimentation.

Let’s see how that works for something like syntax.

A syntactician may like words and morphemes, but what they really care about are the abstract structures underneath,

the skeletons that the meanings are built from.

We can’t see these trees that form the base for our sentences, any more than the naked eye can see an electron.

But we can see the effects that different

kinds of proposed structures have on the world. We can see what changes in meaning happen

when you build one kind of tree rather than another, or when swapping things around

The mission of syntax is ultimately to come up with a system that describes

the structure of every language in the world. All the variation, all the kinds of meanings,

all the deep similarities, we need to capture all of that.

And so to verify a syntactic hypothesis, we need to test it against as many languages as we can find,

and then adjust our thinking as we get more data. Science!

And just like other sciences, what we know about linguistics and how we think of it has changed over time.

Since Noam Chomsky kicked off the generative linguistic parade in the 1950s,

You want to know whether you should use a pronoun or not in Japanese or Italian,

to get the exact meaning you want? We’ve come up with a constraint for that.

You want an explanation for why you can’t say “The operating system said the woman should listen to itself”?

But let’s come back to that syntactician, just sitting around trying to figure out where to start.

and you think, for me, “I’d like to know where who hid the cake” is just bad,

but “I’d like to know where who hid what” is better. And that’s the basis for where you start from,

to look at how we deal with questions. The data comes from intuitions you have

about these sentences from inside your own head! Not everyone will agree right away about these judgments,

but that was originally the case for a lot of the sentences

you find in journals or syntax textbooks. So is that science?
