Abstract

A series of experiments investigated the processing of lipread information, as compared to that of heard and read stimuli, using the repetition priming paradigm. Experiment 1 showed that lipread priming facilitated the semantic categorization of lipread words to the same extent as that found for auditory prime, auditory test, and graphic prime, graphic test conditions. Experiments 2, 3 and 4 measured the effects of crossmodal priming. Lipreading primed both auditory and graphic processing, and is primed by both. While auditory priming did not speed the processing of graphic stimuli, graphic priming facilitated the semantic categorization of heard words. A tentative explanation of the findings is offered: lipreading provides incomplete information about words, and thus there is a need to access stored linguistic knowledge to 'fill in' missing features, allowing identification of the stimulus.

Author Biographies

Barbara Dodd

Barbara Dodd is a Senior Lecturer in the School of English and Linguistics at Macquarie University in Australia. She is a qualified speech pathologist trained at Sydney University; she completed her doctorate at London University in 1974 on the acquisition of phonol-ogical skills in children. She teaches at Macquarie in the areas of psycholinguistics and language disorders. Her research interests include the characterization and treatment of spoken phonological disorders and phonological dyslexia, developing audio-visual methods for teaching lipreading, and the investigation of the behavior of lipread speech in short term memory.

Michael Oerlemans

Michael Oerlemans is a research assistant in the Speech, Hearing and Language Research Centre at Macquarie University and holds a Bachelor of Arts (Honors) degree in Linguistics. His interests center on the description of phonological dyslexia and the investigation of short-term memory coding of stimuli and the implications for this to models of memory.
