The scarce literature on the processing of Internally Headed Relative Clauses (IHRCs) seems to challenge the universality of the subject advantage (e.g., Lau & Tanaka, 2021, for spoken languages; Hauser et al., 2021, for sign languages). In this study, we investigate the comprehension of subject and object IHRCs in Italian Sign Language (LIS) deaf native and non-native signers, and hearing LIS/Italian CODAs (Children of Deaf Adults). We use the eye-tracking Visual-only World Paradigm (Hauser & Pozniak, 2019) recording online and offline responses. Results show that a subject advantage is detected in the online and offline responses of CODAs and in the offline responses of deaf native signers. Results also reveal a higher rate of accuracy in CODAs’ responses. We discuss the difference in performance between the two populations in the light of bilingualism-related cognitive advantages, and lack of proper educational training in Italian for the deaf population in Italy.

Abstract

The scarce literature on the processing of Internally Headed Relative Clauses (IHRCs) seems to challenge the universality of the subject advantage (e.g., Lau & Tanaka, 2021, for spoken languages; Hauser et al., 2021, for sign languages). In this study, we investigate the comprehension of subject and object IHRCs in Italian Sign Language (LIS) deaf native and non-native signers, and hearing LIS/Italian CODAs (Children of Deaf Adults). We use the eye-tracking Visual-only World Paradigm (Hauser & Pozniak, 2019) recording online and offline responses. Results show that a subject advantage is detected in the online and offline responses of CODAs and in the offline responses of deaf native signers. Results also reveal a higher rate of accuracy in CODAs’ responses. We discuss the difference in performance between the two populations in the light of bilingualism-related cognitive advantages, and lack of proper educational training in Italian for the deaf population in Italy.
