On April 18, Mr. José Luis Aedo, the president of the Spanish Confederation of Families of Deaf People (FIAPAS), made a statement during a briefing in Servimedia that we, at the Laboratory of Catalan Sign Language (UPF, Barcelona), think must be refuted due to the severity of its content.
Professor Donna Jo Napoli, from Swarthmore College in the US, one of the authors of the paper we translated and disseminated last year which is available in this very same page (about the scientific arguments that support the idea that all deaf children should be offered a sign language), came to visit the Universitat Pompeu Fabra and gave us a talk about the contents of said paper.
Last spring the journal Language of the Linguistics Society of America (LSA), one of the most important outlets in the field, published an article entitled Ensuring language acquisition for deaf children: What linguists can do. The authors are several Deaf and hearing researchers.
