Over the years the SLLA lab has developed many instruments for use in testing various aspects of linguistic ability in signers, particularly looking at the acquisition of ASL and Libras. Here we share some of the materials we developed for the ASL tests. The tests are grouped according to the appropriate reference to cite if you use one of these tests.
One group of instruments developed for our Bibibi project is described in Quadros et al. (2015). The ASL instruments described in the 2015 publication are available on this page for download and use in future research. Please cite the Quadros et al. (2015) paper for use of ASL instruments described in that paper. For several of these instruments, illustrations were made by the Design Lab at the Universidade Federal de Santa Catarina (UFSC).
Our SLAAASh project spurred us to produce guidelines for calculation of mean length of utterance (MLU) in signing children. We also developed an ASL version of the Index of Productive Syntax (IPSyn; originally developed for English by Scarborough 1990). A more extensive description of these instruments and our results from using them is in preparation. Please cite Goodwin et al. (2019) for the use of these instruments (until we publish the more extensive work).
We plan to add other instruments and update citation information so check back from time to time.
