![][1] ## Psycholinguistic norms for more than 300 lexical signs in German Sign Language (DGS) ## For many spoken languages psycholinguistic norms for variables such as frequency or age of acquisition (AoA) are routinely available and can be used to control for these variables in experiments. Subjective ratings of such variables have been shown to correlate with data dervied from large-scale corpora. As the compilation of sign language corpora is a complex and prolonged endeavour (e.g., work on the [Hamburg Corpus](https://www.sign-lang.uni-hamburg.de/dgs-korpus/index.php/welcome.html) is currently still ongoing), the present project aimed at deriving such psycholinguistic norms for frequency, AoA, iconicity, and transparency for German Sign Language (*Deutsche Gebärdensprache*, DGS) using subjective ratings by deaf and hearing participants. This OSF project contains the collected rating data, stimulus clips including motion tracking data, and the R code used for data analysis. ## How to download norms for DGS ## For quick and easy use the CSV file containing the derived norms (`DGS_norms.csv`) and a lot of additional information about every sign and stimiulus clip can be downloaded by navigating to the "Files" tab in this project. All other data is available from there as well (see `notice.txt` for an overview of the directory structure). ### Versions The most recent version (updated on 26 November 2021) of `DGS_norms.csv` incorporates the following minor changes: - We have added columns containing German and English glosses for each file. - The column "homonyms" was replaced with by the columns "ambiguity_German" and "ambiguitiy_English" which list potential homonyms for each sign in the respective language. - The columns "one_handed" and "two_handed" have been updated and reflect the version of the sign as shown in the corresponding video clip. - The column "animacy" has been updated. - The column "lexical_class" has been updated. By default, OSF will point you to this version. If you want to download the first version of `DGS_norms.csv` please use the OSF version history. ## License ## The norms and data provided here are provided here free of charge in the hope that they will be useful for other researchers studying German Sign Language and sign language more generally.
