What is the 'McGurk effect'?

The McGurk effect is an intriguing perceptual phenomenon that occurs when conflicting auditory and visual stimuli create a different perception than what is presented through either sense alone. In this effect, an individual may watch a video of a person speaking a particular sound, while simultaneously hearing a different sound. The brain attempts to reconcile the discrepancy between what is seen and what is heard, often leading to the perception of a third, entirely different sound. This illustrates the interplay between visual and auditory information in speech perception and highlights how our senses can work together to influence our perception.

The other options focus on different sensory interactions or experiences but do not capture the essence of the McGurk effect. The first option addresses the integration of taste and smell into flavor, which is a different sensory process. The third option relates to memory rather than immediate perception, while the fourth option discusses balance in response to sensory input, which is not related to the McGurk effect's auditory-visual conflict.
