Imagine that you're conducting a study on visual perception in infants. First, you show an infant a picture of a blue square. Then, you present the infant with two pictures- one picture of a blue square and one picture of a green circle. If you find that the infant looks longer at the blue square, we would say that the infant is showing a _________ preference, whereas if you find that the infant looks longer at the green circle, we would say that the infant has been ____________ to the blue square.
