Uma revisão de escopo dos estudos sobre as expressões faciais de emoção e a língua de sinais

Facial expressions of emotion are universal and understood by all human beings. However, for users of sign language, facial expressions are also used as linguistic markers. The objective of this study was to conduct a scoping review of scientific literature on the relationship between the use of sign language and the perception and recognition of facial expressions of emotion. Data were collected from APA PsycNET, Scientific Electronic Library Online –Scielo, and Scopus. A total of 376 publications were identified, and 15 articles were selected according to inclusion and exclusion criteria and PRISMA-ScR guidelines. Most of the publications were made with deaf signers compared to non-signing listeners. The main stimuli used in the studies were static images(photographs of facial expressions of emotion). Most studies did not find significant differences between signers participants with sign language knowledge and non-signers hearing participants.
