Magic Singlish

A number of non-native English speakers get "Singaporean" as the top guess for their native language. You can actually see that by playing around in our dialect navigator. Here's screenshot of a particularly illuminating view:


As you can see, "Singaporean" is connected to a big bundle of non-native dialects. Most of the other native dialects are off in a chain in the bottom right. Here is another view with a slightly weaker filter on connectedness:

Again, you can see that most of the non-native dialects cluster together. Most of the native dialects do not connect directly to that cluster but rather connect to Singaporean. Again, you can see Standard American and AAVE off in their own cluster.

Of course, this view just tells you what is connected to what. It's possible that Swedish is actually more similar to Irish than to Singaporean, even though the chain of connections is farther for Swedish and Irish. If you click on one of the dialects, the panel on the left will show you how closely related that dialect is to all others:

We're working on a browser that will let you see *why* different dialects are more or less related -- that is, what answers in the quiz are typical of which dialects. I'm hoping it will be ready soon. In the meantime, enjoy the dialect browser.

Updated results on the relationship between English dialects

I've updated the interactive visualization of the relationships between the Englishes of the world to include a couple dozen additional native languages. Check it out.

Forums find GamesWithWords

A number of forums have picked up the WhichEnglish quiz, and have produced some really intelligent and insightful conversation. I recommend in particular this conversation on metafilter. There is also an extensive conversation at hacker news and a somewhat older discussion at reddit. And there is a lot of discussion in Finnish and Hungarian, but I have no idea what they are saying...

Handling viral traffic

Around 4am EST on May 28, we started getting *a lot* of traffic to the website. This very quickly overloaded the server, resulting in the website running very slowly. We did some optimization. Things sped up, and our reward was more traffic. So we switched to a more powerful server. And so on.

Things are finally under control. At least for the moment, anyway. You can see that we've managed to get the average page load time down to a reasonable length of time for the last day or so, without any large spikes:



Of course, overwhelming amounts of traffic is a good problem to have, and I won't complain if things overheat again.

Which English: The Science, Part 1

I've gotten a number of questions about the science behind our WhichEnglish quiz. Actually, I had intended to post a more detailed discussion days ago, but I got distracted by other matters.

In this project, we are looking at three interrelated issues:

1. How does the age at which you start learning a language affect how well you learn that language?
2. How is learning a foreign language affected by the language you already know?
3. How are the grammars of different English dialects related?

And of course, we train an algorithm to predict participants' native language and dialect of English based on their answers. I return to that at the end.

Age of Acquisition

Although WhichEnglish has a few scientific targets, age-of-acquisition effects were the original inspiration. Everybody knows that the older you are when you start learning a foreign language, the harder it is to learn. One possibility is that there is a critical period: Up to some age, you can learn a language like a native. After that age, you will never learn it perfectly. The other possibility is that there is no specific period for language learning; rather, language-learning simply gets a little harder every day.

The evidence is unclear. Ideally, you would compare people who started learning some language (say, English) from birth with people who started as 1 year-olds and people who started as 2 year-olds, etc. Or maybe you would want something even finer-grained. The problem is that you need a decent number of people at each age (50 would be a good number), and it quickly becomes infeasible.

One study that came close to this ideal used census data. The authors -- led by Kenji Hakuta -- realized that the US census asks foreign-born residents to rate their own English ability. The authors compared this measure of English ability with the year of immigration (an approximation for the age at which the person started learning English). Their results showed a steady decline, rather than a critical period.

We are trying to build on this work in a few ways. For one, it would be nice to confirm (or disconfirm) the previous results with a more sensitive measure of English ability. So rather than just ask people how good their English is, we have them take a test. Also, we are getting more precise information about when the participant started learning English and in what contexts.

Also, there is good reason to suspect that age-of-acquisition affects different aspects of language differently. Studies have shown that even people who began learning a language as toddlers have detectable -- if very subtle -- accents. However, people who start learning foreign languages as adults usually report that learning vocabulary isn't so hard. Grammar seems to be somewhere in between. The Hakuta study didn't distinguish these different aspects of language.

WhichEnglish focuses on grammar. We also have a vocabulary quiz to look at vocabulary. A pronunciation test is in the works.

First language effects

When we started thinking about studying age-of-acquisition effects, we quickly realized a problem. We needed questions that would be difficult for someone who learned English as a second language. But which aspects of grammar are difficult seems to depend on your first language. I personally have difficulty with aspect in Russian because the English aspect system is much less complex. However, dealing with tense in Russian is relatively straightforward, since the Russian tense system is much less complex that English's.

Since we didn't know for sure what the language backgrounds of our participants would be, we wanted a range of questions that covered the different kinds of problems people with different backgrounds might have.

As we combed the literature, we realized that it was pretty fragmented. One study might say that grammar rule x is difficult for Japanese-speakers and grammar rule y is difficult for German-speakers, but there would be no information on how Japanese-speakers fare with grammar rule y and how German-speakers manage with grammar rule x. This actually makes sense: Most studies look at speakers of one or at most a handful of language backgrounds. This is partly a matter of research interest (the researchers are usually interested in some particular language) and partly a matter of feasibility (in a lab setting, you can only test so many participants). We realized that our study, by virtue of being on the Internet and recruiting people from a wide array of backgrounds, would provide an opportunity to get more systematic data across a large number of languages.

This is pretty exploratory. We don't have strong hypotheses. But as data comes in, we will be analyzing to see what we get, and we will report it here.

The Grammars of English

In designing our age-of-acquisition study, we realized a second problem. Correct English grammar varies across different dialects. In Newfoundland, you can say "Throw me down the stairs the hammer," but most places, you can't. (I have heard that this is said in parts of Rhode Island, too, but only anecdotally.) We don't want to count a late-learner of English who says "Throw me down the stairs the hammer" as not knowing English if in fact she lives in Newfoundland!

So what we really wanted were questions for which the correct answer is the same in all English dialects. But we didn't know what those were. Again, the literature was only partly helpful here. For obvious reasons, researchers tend to be interested in understanding peculiar constructions specific to certain dialects, rather than recording what is the same everywhere (boring).

We picked out a lot of grammar rules that we at least had no reason to believe varied across dialect. But we also realized that there was an opportunity here to study differences across dialects. So we included a subset of items that we thought probably would be different across dialects so that we can explore relationships across dialects.

The algorithm

When you take the quiz, at the end we give you our best guess as to what your native language is and what dialect of English you speak. How is that related to the three issues I just discussed?

It's deeply related. The best way of proving that you understand how people's understanding of grammar is affected by the age at which they started learning, their first language (if any), and the dialect of English they speak, is to show that you can actually distinguish people based on their grammar. In fact, training an algorithm to make just that distinction is a common way of analyzing and exploring data.

There are also obvious practical applications for an algorithm that can guess someone's language background based on their grammar (for education, localization of websites, and so on).

But an important reason we included the algorithm's predictions in the quiz itself was to present the results of the study to participants in the study as the study goes on. Certainly, you can read this and other blog posts I've written about the project as well. But it probably took you as long to read this post as to do the quiz. The algorithm and its predictions boil down the essence of the study in a compelling way. Based on the (numerous) emails I have gotten, it has inspired a lot of people to think more about language. Which is great. The best Web-based studies are a two-way street, where the participants get something out of the experience, too.

We chose the particular algorithm we use because it runs quickly and could be trained on very little data. You can read more about it by clicking on "how it works" in our data visualization. We are testing out more sophisticated algorithms as well, which are likely to do much better. Algorithms for detecting underlying patterns is actually a specialty of my laboratory, and this will be a fantastic dataset to work with. These algorithms mostly run too slowly to use as part of the quiz (nobody wants to wait 10 minutes for their results), but the plan is to describe those results in future posts and/or in future data visualizations.

Good problems to have

GamesWithWords.org will be experiencing periodic outages as we upgrade* the server. The incredible response we've had for WhichEnglish has completely overwhelmed the server. After bringing it back from the dead multiple times, the techs at Datarealm convinced me to upgrade to the next tier of server.

This is possibly overkill, in that we don't normally get the kind of traffic we got today. Over 12% of *all* visitors to the website since Jan. 1, 2008, came in the last 24 hours! Still, traffic has been steadily rising over the last year, and large spikes are getting much more frequent.



Worst case scenario, this should result in a faster, more stable experience for people going forward.

*Upgrading while there is heavy traffic to your website is not ideal. But then neither is having the site crash constantly.

**Update**

After my optimistic comments about "overkill", I've spent most of the last 5 days performing various upgrades to the server. Traffic to the site peaked at about 100,000 visits/day (it was a little lower Sunday, but then weekend traffic is usually down).

There was a lot I could do to shrink page-load time (compressing images, minimizing javascript files, etc.). But the biggest issues were with sending data to and from the database. Here, I did some work to optimize and cut down the number of calls to the database, but the real heroes are the folks at Datarealm, who -- based on the amount of time they've put into helping me with the site over the last week -- have definitely lost money on having me as a client. If you are looking for someone to host your website, I warmly recommend them.

Findings: Which English -- updated dialect chart

I have updated the dialect chart based on the results for the first few days. Since the new version shows up automatically in the frame in the previous post, I haven't added it in here. And you can get a better look at it on the website.

The biggest difference is that also added several "dialects" for non-native speakers of English. That is, I added five new dialects, one each for people whose first language was Spanish, German, Portuguese, Dutch, or Finnish. I'll be adding more of these dialects in the future, but those just happen to be the groups for which we have a decent number of respondents.

As you can see, the algorithm finds that American & Canadian speakers are more likely one another than they are like anyone else. Similarly, English, Irish, Scottish, and Australian speakers are more likely one another than anyone else. And the non-native English speakers also form a group. I'll leave you to explore the more fine-grained groupings on your own.

If you are wondering why New Zealanders are off by themselves, that's mostly because we don't have very many of them, and the algorithm has difficulty classifying dialects for which there isn't much data. Same for Welsh English, South African English, and Black Vernacular English. So if you know people who speak any of those dialects...

The English Grammars of the World

It's widely observed that not everybody speaks English the same way. Depending on where you grew up, you might say y'all, you guys, or just you. You might pronounce grocery as if it were "groshery" or "grossery." There have been some excellent, fine-grained studies of how these aspects of English vary across the United States and elsewhere, such as this one.

But vocabulary and pronunciation aren't the only things that vary across different dialects of English. We are in the midst of a soft launch of a new project which will, among things, help map out the differences in English grammar around the world.

I put together a visualization of early results below (you may want to load it in its own page -- depending on your browser, the embedded version below may not work). You can use this graphic to explore the similarities among nine English dialects (American, Canadian, English English, Irish, New Zealandish,  Northern Irish, Scottish, and South African).

As more results come in (about other dialects like Ebonics and Welsh, about specific parts of America or Canada, etc.), I'll be updating this graphic. So please take the survey and then check back in soon.

Doing your homework

I just finished a radio interview about birth order.

Apparently not very much research goes into booking guests for radio & TV shows. Lately, I've been getting at least one interview request a month to talk about birth order. And every time they are disappointed that I can't tell them about how birth order affects personality, that there's little evidence to suggest it does. They *wouldn't* be surprised if they read *anything* that I had written or said on the topic. (Well, except for that FOX interview, which was edited to make it look like I said the exact opposite of what I actually said.)

It's been making me think I should do more birth order research, just so I have something to say at these interviews.

Calling all citizen scientists

SciStarter would like to know more about your experiences with Citizen Science. They are running a survey (here) in preparation for a workshop at the Citizen CyberScience Summit in London next month.

More Citizens, More Science


For the last couple years, most articles about Citizen Science -- in which amateurs contribute to scientific projects -- have been hagiography. These articles were nearly exclusively Ra! Ra!, all about the exciting new development.

It seems that we've matured a bit as a field, because lately I've run across a couple articles that, while still being positive overall, have laid out some real criticism. For instance, in an article in Harvard Magazine, Katherine Xue concludes with the worry that citizen science may be less about involving the public and more about cheap labor (full disclosure: I was interviewed for and appear in this article). Many citizen science projects, she notes, are little more than games or, worse, rote labor, with little true engagement for the volunteer in the scientific mission.

Similarly, in a much-tweeted article at The Guardian, Michelle Kilfoyle and Hayley Birch write, "Who really benefits the most from [citizen science]: the amateurs or the professionals? … Most well-known initiatives are the big crowdsourcing projects: big on the number of participants but not necessarily the level of participation."

Introducing the VerbCorner Forum

These articles resonated with me. Ever since we launched VerbCorner, our citizen science project looking at the structure of language, meaning, and thought, we've wanted to find additional ways to get our volunteers involved in the science and get more out of participation. VerbCorner is very much a crowdsourcing project -- most of what volunteers do on the site is contribute labor. We've always had this blog, where people could learn more about the project, but that's not especially interactive.

To that end, we've added a forum where anyone and everyone involved in the project can discuss the project, offer suggestions, debate the science, and discuss anything related (syntax, semantics, etc.). We have high hopes for this forum. Over the years, I have gotten a lot of emails from participants in the various projects at GamesWithWords.org, emails with questions about the projects, ideas for new experiments, and -- all too often -- reports of bugs or type-os. These emails have been extremely useful, and in a few cases have even led to entirely new research directions. But email is a blunt instrument, and I expect that for everyone who has emailed, at least ten others had similar comments but never got around to tracking down our email address.

I hope to see you on the forum!

A Great Year for GamesWithWords.org

Unique visitors at GamesWithWords.org were up 76% in 2013 over the previous year. That's after several years of fairly steady traffic.

Meanwhile, two journal papers and a conference paper involving data collected at GamesWithWords.org were accepted (and two more are currently under review). Many thanks to everyone who participated and otherwise helped out!
