An experiment is conducted where a newborn infant is seated in front of two video screens. Screen A displays a person speaking, with the audio perfectly matching the lip movements. Screen B displays the same person speaking the same words, but the audio is slightly delayed, causing a mismatch between the sound and the lip movements. An eye-tracker measures how long the infant looks at each screen. Which outcome would you predict, and what is the most accurate interpretation of that outcome?
