Sensory interaction is best illustrated by

A) psychokinesis.
B) the volley principle.
C) the McGurk effect.
D) phantom limb sensations.

The McGurk effect is a phenomenon in which our perception of speech sounds is influenced by the visual cues we receive while the sounds are being produced. This is an example of sensory interaction, as our perception is being influenced by multiple senses working together. Psychokinesis is a term used in parapsychology and has no relevance to sensory interaction. The volley principle refers to how groups of neurons fire together to produce a perception of sound, but this is not an example of sensory interaction. Phantom limb sensations, while involving multiple senses (such as touch and vision), do not necessarily involve interaction between those senses.
