This research consists of an eye-tracking study examining the efficacy of eye gaze indexing (EGIX) in manipulating viewer eye gaze and enhancing second language (L2) fingerspelling comprehension in American Sign Language (ASL) through a controlled laboratory experiment. The study consisted of two groups and two conditions, EGIX+/EGIX- to test the…

The comprehension of signed language requires linguistic and visual-spatial processing, such as perspective-taking for correctly interpreting the layout of a spatial scene. However, little is known about how adult second-language (L2) learners process visual-spatial constructions in a signed language that they are studying, including which angles…

Perception of American Sign Language (ASL) handshape and place of articulation parameters was investigated in three groups of signers: deaf native signers, deaf non-native signers who acquired ASL between the ages of 10 and 18, and hearing non-native signers who acquired ASL as a second language between the ages of 10 and 26. Participants were…

Individual signs were presented to deaf fluent signers both in context and without context. Within context, signs were isolated sooner, perfect confidence in the response was reached sooner, and a narrowing-in process was found that was both semantic and phonological. Current spoken-word-recognition models could be modified to reflect…

Interest is focused on the relationship between how old a person is when he or she first begins to learn a language and the fluency with which he or she can produce and understand that language in adulthood. The goal is to describe and measure the relationship between early experience and environment in language learning. In particular, the…
