Valter Ciocca completed his undergraduate studies in Experimental Psychology at the University of Padua (Italy). He subsequently went to McGill University, where he completed his Ph.D. in the Department of Psychology under the guidance of Albert Bregman, with a thesis on the application of auditory scene analysis principles to speech perception. He then continued his research training with Chris Darwin at the University of Sussex, where he investigated the effects of auditory grouping on pitch perception. In 1992, he joined the Department of Speech and Hearing Sciences at Hong Kong University, where he applied his knowledge of auditory perception and speech science to the study of Cantonese speech and of lexical tones. At Hong Kong University he extended his research to the study of populations of listeners and speakers with communication disorders (individuals with cerebral palsy and hearing impairments, including cochlear implant users), as well as adults with normal communication abilities and typically developing children. Since 2007, he joined the School of Audiology and Speech Sciences at UBC as the School’s Director.
My research has so far focused on three main themes within the field of speech and hearing sciences: auditory scene analysis, speech perception and production, and pitch perception and production.
My current projects include:
1. the perception of the illusory continuation of interrupted sounds through louder noise and through short gaps of silence. This phenomenon is usually referred to as “temporal induction” or “auditory continuity”. Within this project I am investigating the perception of auditory continuity by listeners with normal hearing and by cochlear implant users.
2. the study of auditory processing abilities of individuals with autistic savant syndrome.
My current collaborators include: Denis Burnham (MARCS, University of Western Sydney; Laurent Mottron (Department of Psychiatry, Université de Montréal); Tara Whitehill, Anita Wong, and Lena Wong (University of Hong Kong); Patrick Wong (Northwestern University) Sipke Pijl and Brian Westerberg (UBC)
