A meta-analysis of outcomes for late talkers
The extreme variability in outcome of late talkers raises challenges both for theoretical work on the sources and development of individual differences in early language development, and for clinical/educational practice. Research on long-term outcomes is sparse but growing, though primarily focused on English. There is need for increasing the research database, and especially for integration of research across languages. We are undertaking a cross-linguistic meta-analysis of outcomes for late talkers. In addition to published and unpublished papers specifically focused on this issue, we believe there are projects which may have another primary focus, but which include an early (18-36 month) assessment of expressive vocabulary, and language and/or literacy outcomes at age 5 years or beyond. The target studies can include broadly representative samples, or late talkers specifically. If you are interested in the possibility of collaboration on this project, please contact either of us listed below. You may also find the PROSPERO registration of this project helpful in understanding our plans:https://www.crd.york.ac.uk/PROSPERO

Mike just taught a course at the University of Amsterdam LOT winter school on "Language Learning: A Data-Driven Approach." Here's the course description:
In this course, we will examine early language learning through the lens of new data resources that facilitate quantitative studies. Our framework will be the "Standard Model" of Kachergis, Marchman, and Frank (2022) that links language input to processing and learning outcomes, and we will consider the strengths and weaknesses of this model for describing vocabulary learning as well as the learning of some morphology and syntax. Our hands-on approach will involve learning the use of CHILDES and childes-db for studying language input, Wordbank for studying language outcomes, and Peekbank for studying processing.

We are very pleased to announce a major update to Wordbank, including some significant changes to the database structure. We are also adding more than 10 new languages and data from many thousands of children.
We now include data from multilingual children and children with diagnosed developmental disorders (as well as functionality for identifying these children via the shiny apps and the wordbankr API).
The prior version of the Wordbank database will remain up and available for queries via the wordbankr 0.3.0 API (or earlier) for a period of at least 6 months, but if you upgrade wordbankr you will begin accessing the new Wordbank data.
Wordbank data will also be versioned going forward so that older snapshots of the database will be available via S3 snapshots (see Documentation page).

We are very pleased to announce publication of the Wordbank Book, "Variability and Consistency in Early Language Learning," now available from MIT Press (2021). The book brings together many different ways of looking at data in the Wordbank database, in service of characterizing how children vary as well as shared patterns of learning. The book is also available free online at http://wordbank-book.stanford.edu, and all of the code necessary to generate it from the Wordbank data can be found at http://github.com/langcog/wordbank-book.

More languages (and some naming changes)
We are pleased to announce several pieces of news:
First, the arrival of several more languages and datasets, including French (European), more Korean data, as well as more Hebrew data and Spanish (European) in the works.
Second, we have a new licensing standard such that some datasets can be licensed Creative Commons for Non-Commercial use. These datasets are marked on the contributors page.
Finally, because of the new data, we have some new naming conventions for languages. "English" is now "English (American)"; this convention will generally be followed as "Language (Country/Region)." These are breaking changes unfortunately, we apologize for the inconvenience and are working on past database images available for purposes of reproducibility.

New frontpage and languages
Since our last update, we've reorganized the frontpage and revamped the contributors and citation policy. We've also added Latvian, Slovak, and Korean data!
Friday, September 30, 2016
We're pleased to announce a number of new languages in Wordbank, bringing us up above 20 languages. The new data are from ASL, Cypriot Greek, Kiswahili and Kirigama. We also have added British English short-form data from the Twins Early Development Study (TEDS). Take a look at these new additions!
Wednesday, April 20, 2016
We now have a FAQ!
Also, check out the semantic networks report and the new scoring tool.
Stay tuned for some new languages in the next few months.

Our R package for accessing wordbank is now on CRAN! You can now install and use wordbankr
even more easily.

Paper under review
We are happy to announce that we have a new paper on Wordbank and the wordbankr package now under review. For now, this is the appropriate citation for the wordbank site:

We've been working on improving how you can access the Wordbank data from R, and the result is the wordbankr
package. It's still a work in progress, so a lot of it may change, but using it you can now pull in data by-administration, by-item, and administration-by-item, with minimal hassle. Check out the package vignette
for a tutorial!

We've just pushed an update to our analysis pages so that they include much more content. We not only have interactive visualizations (like the norms and items tools), we also have a number of non-interactive reports that we've put together on topics like gender differences, SES effects, etc. You can also see analyses from our CogSci paper this year
on grammar-lexicon relationships. Let us know if you have comments (or analyses you'd like to add)!

We're excited to announce we've imported all of the CDI norming data from CLEX
. Thank you to Rune Nørgaard Jørgensen! Wordbank now has almost 40,000 CDI administrations, across 10 different languages (Croatian, Danish, English, German, Italian, Norwegian, Russian, Spanish, Swedish, and Turkish).
Sunday, March 15, 2015
Check out our new reports that let you explore our data, filter and sort it to suit your needs, and download it as a csv file. There's one report for by-administration data
, with overall vocabulary sizes and demographic information, and one report for the full administration-by-item data
. Also, all of the analysis reports now let you download the plot and the data being plotted!

We've spent the last few months overhauling Wordbank's data import to support adding in many datasets in different languages. Yesterday these updates went live, and Wordbank now has data in English, Spanish, Danish, and Norwegian, including both Words & Sentences and Words & Gestures. It's a total of almost 30,000 CDI administrations! Check out our reports
to play around with all of these datasets, or look at this tutorial
on accessing Wordbank from R if you're interested in running your own analyses.

Welcome to Wordbank's blog!
This is the place where we will be announcing new features and datasets for the wordbank site (wordbank.stanford.edu
). Stay tuned!
