Final answer:
The McGurk effect best illustrates sensory interactions, where different senses interact to influence perception.
Step-by-step explanation:
McGurk Effect and Sensory Interactions
The McGurk effect best illustrates sensory interactions. Sensory interactions occur when different senses interact with each other to influence perception. In the case of the McGurk effect, it is a perceptual phenomenon where what we see affects what we hear.
For example, if someone says the sound /ba/ while the video shows the lip movements of someone saying /ga/, our brain integrates the visual and auditory information, resulting in us perceiving /da/. This shows how vision can override or influence the auditory perception.
