Object Recognition in Fish: Scientist Trains Goldfish to Touch Objects for Food Rewards
Posted on October 26, 2011
Caroline DeLong, an assistant professor of psychology at Rochester Institute of Technology, has trained goldfish to recognize objects. The experiments show that the fish can tell the difference between shapes, such as a circle or a rectangle. In the experiment, the goldfish is rewarded with a treat if it taps a circle with its mouth, but it does not get a reward if it taps the rectangle.
DeLong says, "Since I was a child, I have been fascinated by how animals communicate and view the world. If I could magically view the world through a dolphin's eyes for a day, I would. Humans view the world using our own sensory systems, and it's amazing to begin to learn how all these different animals view their world using their own sensory systems."
