Fiorito and Scotto placed the common octopus in an experimental situation to see if it could learn through observation. In their experiment, an observer octopus watched while a demonstrator octopus was either rewarded for choosing the right ball or punished for choosing the wrong one. What did the researchers conclude from this study?
The observer octopus demonstrated learning because it chose the "rewarded" ball more quickly and more frequently than an octopus that had no experience with the task.
