Link Party Trick

Once you get some practice using the Link System [ For more on 'Link System' go here: http://www.braingle.com/mind/89.html ] to remember lists of items, you can use it to perform an amazing party trick.

Tell everyone that you have a super memory and that you can remember twenty items after they are called out only once. Designate someone as the record keeper to confirm your feat.

Now, you should pick someone to call out an object. Create a visual association [ For more on 'visual association' go here: http://www.braingle.com/mind/448.html ] between this first object and yourself. This will help you remember the first item.

Now point to someone else and have them call out another object. In your mind, make a link between the two objects. Continue linking each object to the next until you have reached the end. Because you are controlling the pace that items are being called out, you can go as slow as you need to as you create your visual imagery. Naturally, the faster you go, the more impressive the trick will be.

Once you are done, it should be easy for you to recall all twenty items in order. Most people do not realize that anyone can have this type of memory with only a little practice.
