Answer:
The correct answer is letter A. Violation of expectations.
Step-by-step explanation:
We need to pay close attention to the question, otherwise we might be tempted to choose letter B. What was described does comprise the use of habituation and dishabituation, but the name of the method used is violation of expectations. This method is based on the idea that infants will be surprised when they watch an impossible event take place. Since the event is not what the infant expected, they will show dishabituation - they will look at it for a longer period of time than they would if it were a situation they could predict. An event they have seen multiple times would cause habituation, and the infant would lose interest and look away more quickly.
