Perception <strong>of</strong> Phonological Structure in American Sign Language<br />

Status: Ongoing Begin date: April <strong>2008</strong> End date: December 2010<br />

Principal Investigator(s):<br />

Mathur, Gaurav – Linguistics<br />

Description:<br />

The study investigates how language experience and parameters <strong>of</strong> phonological structure<br />

affect perception in ASL. To examine perception, the study uses a number <strong>of</strong> experimental<br />

techniques in psycholinguistics. One technique, primed lexical decision, determines whether one sign<br />

facilitates the recognition <strong>of</strong> another sign if they share a parameter in common. Another technique,<br />

primed phonological matching, determines whether participants can detect a slight phonological<br />

difference between the two signs produced by different signers. To evaluate the effects <strong>of</strong> language<br />

experience, performance on these tasks are compared across both Deaf and hearing individuals in<br />

several groups: those exposed to ASL from birth; those exposed to ASL after five years <strong>of</strong> age; and<br />

those with no prior ASL exposure. The study helps to identify aspects <strong>of</strong> linguistic structure<br />

prominent in perception and to determine the degrees <strong>of</strong> signed language fluency with respect to<br />

perception, which can be applied toward language assessment.<br />
