Example: Article: Homework can put you in a badmood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

In fact, more than 50 percent of another's impression, he believes, is influenced by the look on your face. Naturally a smile in which the eyes participate is extremely communicative. An unfriendly look often brings the same thing in return. People tend to mirror your expression, so try to show how you feel about a topic or an idea or the audience through your facial expression. 2. Rid Your Inner Fear It's natural to have some tension or nervousness when you appear before an audience. The way to handle it is to put it to work for you, get into action, as Shakespeare observed, action cures fear. There are only a few known ways to control fear. The first is to admit it, do the thing you fear and it will be the death of fear itself. Another simple aid at the last minute before you begin, is to take a few deep breaths, this will help get the butterflies in formation and also keep your voice under control. In fact, if you're thoroughly prepared, just taking a few deep breaths before you're introduced will give you added confidence and balance.

Polish Your Voice Our voice is the main instrument we possess for communicating with people, we're all sound sensitive. So invest in a tape recorder, practise your speech by speaking it into the microphone then listen to it. You can even have others join in the evaluation of your strong points and your weaknesses or faults as well.

Simply reading out loud can also help you improve your voice and develop a personal style. 4. Strengthen Your Memory Psychologists tell us that most individuals don't use above ten percent of their natural capacity for memory, that's comparable to trying to run a car on one cylinder . Why do most people use so little of their power of memory? Because they don't practise the fundamentals of remembering. First and most important, it's necessary to have a burning desire to remember, it's difficult to recall anything without wanting to do so. Step number two is concentration. Henry Ward Beecher once observed, one hour of intense concentration can accomplish more than years of dreaming. The next principle is repetition, we learned many things in school by rote by repetition, when you hear a name for the first time repeat it, spell it, write it down, review it, you'll soon know it by heart.
