| Abstract: | American Sign Language (ASL) uses the face to express grammar and inflection, in addition to emotion. Research in this area
has mostly used photographic stimuli. The purpose of this paper is to present data on how deaf signers and hearing non-signers
recognize and categorize a variety of communicative facial expressions in ASL using dynamic stimuli rather than static pictures.
Stimuli included six expression types chosen because they share overt similarities but express different content. Hearing
participants were more accurate in their categorizations but expressed overall lower confidence regarding their performance.
