The impact of face masks on metacognition in sign language is mediated by proficiency.

Face masks can impact processing a narrative in sign language, affecting several metacognitive dimensions of understanding (i.e., perceived effort, confidence and feeling of understanding).

Deaf adolescents' quality of life: a questionnaire in Italian Sign Language.

For some deaf people, sign language is the preferred language, the one in which they feel most comfortable. However, there are very few assessment tools developed or adapted for sign languages. The aim of this study was to translate and adapt in Italian Sign Language (LIS) the Italian version of the Youth Quality of Life Instrument-Deaf and Hard of Hearing Module (YQOL-DHH).

The effect of face masks on sign language comprehension: performance and metacognitive dimensions.

In spoken languages, face masks represent an obstacle to speech understanding and influence metacognitive judgments, reducing confidence and increasing effort while listening. To date, all studies on face masks and communication involved spoken languages and hearing participants, leaving us with no insight on how masked communication impacts on non-spoken languages. Here, we examined the effects of face masks on sign language comprehension and metacognition.

The body and the fading away of abstract concepts and words: a sign language analysis.

One of the most important challenges for embodied and grounded theories of cognition concerns the representation of abstract concepts, such as "freedom." Many embodied theories of abstract concepts have been proposed. Some proposals stress the similarities between concrete and abstract concepts showing that they are both grounded in perception and action system while other emphasize their difference favoring a multiple representation view.
