Researchers typically use the length of time that an infant gazes at an object to determine their interest. This is known as time preference and is often used as a measure of attentional preference. Other measures, such as whether or not the infant looks directly at the object, may also be used, but are typically less reliable than measuring gaze duration. Signs of boredom, such as yawning, are generally not considered accurate measures of infant interest. Smiling at an object is often interpreted as a positive emotional response, but does not necessarily indicate sustained interest.
