Problem
While studying his hard-earned notecards, another mascot from another university wanders through the library, wearing a jersey with the number 15 on it. Shocked, Goldy rubs his eyes for a moment and doesn't detect any changes in the strange scene. However, in reality, while Goldy rubbed his eyes (while he didn't see the scene for a moment), the other mascot quickly put on a different jersey with a 42 on it.
i. What effect likely caused Goldy to miss the jersey change
ii. Why might the affect from part a affect actually be adaptive in some circumstances?
