William Roberts and his colleagues made a discovery on rats. They found out that rats are able to track how much time has passed since they last discovered a piece of cheese, but they can't remember where exactly they found that piece of cheese. William Roberts used a experiment to show everyone that rats can remember how much time has passed since they found cheese. He got rats in the 'arms' of the maze at different times of the day. In the maze he placed moderately diserable food pellets and highly diserable cheese. Rats were then being tested on when, how long, or both. This discovery lead researchers to think that episodic-like memory in rats is qualitatively different from human episodic memorys.
I think this is a very interesting discovery because i didn't think rats could actually track how much time has passed since they found cheese. In the future i think rats will be able to remember where they last found the cheese and remember how much time has passed.
