Schüller-NGT-SRT

This relates, for example, to the age of acquisition of NGT, the type of education followed by the signer, and whether the signer grew up with hearing or deaf family members. Given the lack of suitable language assessment tools available to tap into this variation in NGT fluency in adults (L1/L2), we developed an efficient (short and simple) NGT assessment tool.

After exploring the range of existing assessment tools as described by Enns et al. (2016), we developed a sentence repetition task (SRT) for NGT, the Schüller-NGT-SRT. In line with the existing SRTs (ASL-SRT, Hauser et al., 2006; BSL-SRT, Cormier et al., 2012; DSGS-SRT, Haug et al. 2015), thirty-nine sentences were created, varying in length and complexity. The different levels of complexity were developed conform a combination of guidelines for the existing SRTs in signed languages, guidelines developed by Mayberry (unpublished) for a related test, and guidelines developed in the European COST project, which focused on SRTs in spoken languages: Action IS0804, described by Marinis and Armon-Lotem (2016).
