Sign language processing in the visual world

When perceiving language, listeners must interpret input dynamically by incrementally tracking multiple sources of information. Signed languages present a unique challenge for real-time recognition, because the visual modality of sign requires the signer to interpret the linguistic and referential context simultaneously. I will discuss a series of studies with deaf children and adults who use American Sign Language (ASL), in which we investigate real-time processing of sign language. Using a modified visual world eye-tracking paradigm, we present signers with ASL stimuli and accompanying visual information to determine how signers allocate and alternate visual attention as the linguistic signal unfolds. We find that both adult and child signers interpret signs dynamically, and make anticipatory eye movements to a target when the linguistic signal constrains its identity. Together, these studies suggest that ASL processing is driven by predictive relationships between the unfolding linguistic signal and the surrounding visual scene in ways that are both parallel to and divergent from spoken language processing.
