An instrument must be calibrated and checked against known standards if the readings are to be trusted. The theoretical best accuracy for most commercially available non-laser-based instruments is attained in the range near 1 AU. The path length or concentration should then, when possible, be adjusted to achieve readings near this range.
Then try any of the Other Mental Strategies that sound promising to you. Give them an honest try -- use them for at least three days. If you notice a little change, that suggests that the skill will be valuable and, with continued practice, will greatly improve your concentration.
Be Here Now This deceptively simple strategy is probably the most effective.
When you notice your thoughts wandering astray, say to yourself "Be here now" and gently bring your attention back to where you want it. As you say to yourself "Be here now" you focus back on the lecture and maintain your attention there as long as possible.
When it wanders again, repeat "Be here now" and gently bring your attention back. You may notice that your mind often wanders as often as several times a minute at times.
Each time just say "Be here now" and refocus. Do not try to keep particular thoughts out of your mind.
For example, as you sit there, close your eyes and think about anything you want to for the next three minutes except cookies. Try not to think about cookies When you try not to think about something, it keeps coming back.
So be patient and keep at it. But it is the basis for concentration because it helps you to maintain your concentration and not give in to distractions. Hold a vibrating tuning fork next to a spider web. The spider will react and come looking for what is vibrating the web. You can learn that. Train yourself not to give in to distractions.
When someone enters the room, or when a door slams, do not allow yourself to participate. Use the "Be here now" technique to help you regain concentration when you do become distracted momentarily.
Practice this in a variety of settings, such as: In lecture classes practice letting people move or cough without having to look at them - just let them "be out there" while you form a tunnel between you and the lecturer. When talking with someone keep your attention on that person, look at his face, and note what is being said.
Let the rest of the world just be "out there. For example, set 4: When your mind is side-tracked into worrying during the day, remind yourself that you have a special time for worrying.
Then, let the thought go for the present, and return your focus to your immediate activity. Persons who use a worry time find themselves worrying 35 percent less of the time within four weeks. The important steps are: Tallying your mental wanderings.
Have a 3 x 5 inch card handy. Draw two lines dividing the card into three sections.
Label them "morning," "afternoon," and "evening. Keep a card for each day. Remember to take short breaks. Your concentration time-span might be less minutes or longer perhaps 90 minutes.
When you take a break, oxygenate get more oxygen to your brain! Get up and walk around the room for a couple of minutes. When we sit for long periods, blood tends to pool in our lower body and legs because of gravity. Our calves serve as pumps for our blood when we walk, getting blood flowing more evenly throughout the body.
As a result, more oxygen is carried to the brain and you are more alert. Many students aid their concentration by changing the subject they are studying every one to two hours.The UCI has announced that Chris Froome has given an Adverse Analytical Finding for Salbutamol following a test during the Vuelta a España.
