Gerardo’s research explores different aspects related to the acquisition and processing of sign languages. He has explored how iconicity has an impact on the acquisition of a manual phonological system by hearing adults. He has also investigated how different types of iconicity influence the acquisition of a sign language by deaf children. His research has looked at Mexican Sign Language (LSM), British Sign Language (BSL) and Turkish Sign Language (TID) under a range of experimental paradigms. He was recently awarded a Veni NWO grant for the project ‘The role of gesture during the acquisition of a sign language as a second language’. In this collaborative project with Aslı Özyürek, he will use behavioural and electrophysiological methods to investigate how gesture and iconicity influence the production and perception of Sign Language of the Netherlands in second language learners.
