Lerning and Memory (2)

I came with answer early...

Animals & Memory

Animals - An Elephant never forgets

There is a story about a circus elephant named Maybelle who didn't like a particular elephant handler. Ten years after the man retired, the circus came through his town, and he decided to come visit. Maybelle gleefully snuck up behind him and squirted him with a trunk full of water. She hadn't forgotten him! (Kurland and Lupoff, 1999, page 31)

Animals - Fish Activity

You may be surprised to learn how many animals actually have a memory. Even your goldfish can show evidence of learning capability. If you have a pet fish, try this experiment. Every day when you feed the fish, sprinkle the food only in the exact same location.

Keep a record of daily observations of the fish, jotting down notes about the fish's swimming patterns or behavior whenever you come to feed it. Before long, the fish should swim to the spot where you sprinkle the food whenever you approach the tank. See how it reacts to your approaching the tank and take notes before, during, and after your experiment.

In this example of animals' memory, we don't really know if your fish is aware of the fact that you are going to feed it. It could simply exhibiting a conditioned reflex. But either way, it has displayed its ability to learn and to remember.

Animals - Bees

Bees communicate with each other in a way which demonstrates an intelligent memory. When a bee finds a location particularly plentiful for gathering nectar, it will remember how to get to this location from its hive. The bee then returns to the hive and passes along its memory by doing a complex dance to inform the others of where the food was found. It uses wings, legs, antennae and body to deliver the message. When the dance is over, other bees fly to the identified location to bring back food for the hive. (Kurland and Lupoff, 1999, page 36)

Preventing Brain-Freeze

Animals who hibernate have a substance between their cells that act like antifreeze so that the water in their body doesn't freeze and their brain cells are not damaged. (Freed, 2000.p.2. Scientific American article)

Birds Memory

Earlier it was thought that probably nutcrackers remembered only the general area where their seeds were stored, or that perhaps they could smell the seeds. Now after many ingenious experiments, the truth is known. When it comes to remembering where their food is stored, nutcrackers have amazing memories. Their memories are not faultless, but nutcrackers are surely more gifted for this single cache-remembering task than average humans. If you hid seed in five or six thousand tiny holes in the ground scattered over a mountain slope, in several months' time could you remember where most of them were?

If this does not convince you go to my link section, you will find a link to this subject.....

Hmm I am sure you will start thinking differently about animals after this!
