Mouthing in Kufr Qassem deaf community

A recent study (Jaraisy 2021) has shown that mouthing is not a prominent feature in KQSL. In Jaraisy (2021), participants from the first and second-generation mouthed in only 8% of the signs produced. In addition, a follow-up study within the same larger study (Jaraisy 2021) has shown that third-generation deaf signers in the Kufr Qassem deaf community change their mouthing patterns and frequency when they use KQSL or communicate with a KQSL user from the second generation. That is, their mouthing decreases when they switch to KQSL (regardless of the interlocuter - meaning that when even when they use KQSL with an ISL signer, their mouthing frequency decreases), and when they communicate with a KQSL signer from the second generation (regardless of the language - meaning that even when they use ISL with this interlocuter, their mouthing decreases)
