    To investigate the process underlying audiovisual speech perception, the McGurk illusion was examined across a range of phonetic contexts. Two major changes were found. First, the frequency of illusory /g/ fusion percepts ...
  • Guenther, Frank; Nieto-Castanon, Alfonso; Ghosh, Satrajit; Tourville, Jason (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2002-09)
    We used functional magnetic resonance imaging (fMRI) to investigate the representation of sound categories in human auditory cortex. Experiment 1 investigated the representation of prototypical and non-prototypical examples ...
