Playing Hide-and-Seek with Rats Researchers studying animal behavior have found that rats can quickly learn to play hide-and-
seek with humans.The rats seem to love the game, squeaking and jumping for joy when they fınd the human or are found by the
human. The game is played in a large room with multiple boxes. Some of the boxes are transparent and easy to see through, while
others are opaque and the inside cannot be seen. Rats go in and out of these boxes and the researchers studied whether they
treated the boxes differently depending on whether they were hiding (and didn't want to be seen) or seeking (and didn't care if
they were seen). For rats who had been learning the game for about a week, the data' on the number of times the rats entered the
two types of boxes in each situation are shown in the table below.
