In infant studies, violation-of-expectation is used to test language processing by...

• A. Infants look longer when expectations are violated; used to test grammar or word-segment recognition
• B. Infants show reduced attention when bored
• C. It measures preference for social interaction
• D. It assesses motor imitation

Answer: (A)

Violations of expectations in infancy studies tap into how babies process language rules. The idea is that infants build mental models of language patterns—like grammar or how speech streams are segmented into words—and then researchers watch what happens when those patterns are violated. When an event contradicts what the infant has learned, they tend to look longer, signaling surprise and increased processing as they try to make sense of the unexpected input. This looking-time difference provides evidence that preschoolers have picked up on linguistic structure even before they can verbalize it. So, using a violation-of-expectation paradigm to test grammar or word-segment recognition makes sense because the key measure is the infant’s increased attention to an outcome that breaks the learned language rule. The other options describe general attention, social preference, or imitation tasks that don’t specifically reveal processing of language structure through expectation violations.
