  • Memory : Effective Associations : Craziness
    on 23/02/2018 at 12:00 am

    Many mnemonics rely on making visual associations in your mind. The nature of these visualizations has a lot to do with how well you will remember them. Making crazy associations in your visualizations will help you remember the information later. If you are trying to associate a dog with a stapler, a poor association would be a dog standing on a stapler. The brain filters out and forgets things that are ordinary. If you get a little crazy, you'll have a more memorable association. Maybe you could picture a dog with a stapler for a mouth! In addition to making the images more interesting, crazy associations tend to take more time to form and thus give you a better chance at getting them into your long-term memory. Here are two techniques that will help make your associations crazier. 1. Try a substitution. For example, substituting a stapler for a dog's mouth. 2. Try an exaggeration. For example, a giant stapler chasing a scared dog down the street. […]

    One Lump or Many? The following is a true story. My friends and I were enjoying the atmosphere (and food) at an authentic English pub in town. We all ordered tea, and the barmaid brought us all our preferred variety. She passed by each of us and asked, "Would you like milk or lemon?" One of my friends simply said "Yes" and quickly poured a bit of milk and squeezed a lemon wedge into his cup. He passed the milk back to the young lady who smiled and said "I'll be right back with another cup for you, sir." My friend was confused at first, but upon her return he was happy to have a fresh cup. What had happened to necessitate a new cup of tea? Check Braingle.com for the answer. […]

  • Creativity : Taboos
    on 23/02/2018 at 12:00 am

    A taboo is an inhibition resulting from social customs or emotional aversion. Taboos serve a useful purpose to society because they prevent people from getting into uncomfortable situations. However, taboos can cause people to ignore certain solutions to problems, even if these solutions are very good. A popular example is to imagine a pipe stuck in the ground with a ping-pong ball in the bottom. How do you get the ping-pong ball out using a minimum of supplies and without damaging anything? The taboo answer is to pee into the pipe, thus floating the ball out. This is a very effective solution and you may have thought of this answer, but if you had been in a group of people, you probably would not have verbalized it. Since taboos exist to protect other members of society, you do not need to censor yourself when you are working alone. You might not end up with a taboo solution, but sometimes you must think through incorrect or unacceptable solutions in order to reach a correct one. […]
