The typical finding in experiments on the McGurk effect is that the visual stimuli, the moving mouth, influences what people report hearing. This is known as audio-visual integration, where the brain integrates information from multiple senses to form a single perception. In this case, the visual mode dominates over the auditory mode, leading people to perceive a sound that is influenced by what they see. Option B is incorrect because it suggests that speech perception is strictly a product of what is heard. Option C is also incorrect because the visual and auditory perceptions do not necessarily interfere, but rather integrate. Option D is incorrect because it suggests that participants attribute what they hear to the mouth in question, which is not necessarily the case.
