Suppose you perform an experiment in which you allow a group of babies to suck on one of two different pacifiers. Some babies sucked on the one that was smooth and round and other babies sucked on the pacifier that had ridges on it and was oblong. Later, you show both pacifiers to the babies. Generalizing from similar research reported in the text, you would expect that the babies would look: longer at the pacifier that they had sucked on longer at the pacifier that was "new" equally long at both pacifiers at neither pacifier, since sucking on a "weird" pacifier was unpleasant for them
