Discussions on Psychological Theory. Discussions on Psychological TheoryPresent paper deals with the discussions of the psychological theory and its main principles. According to this theory, usage of drugs and people’s addiction to them can be explained by different factors. The first case under discussion is usage of drugs because of two main factors contributing it. They are reinforcement and personal problems. I completely agree that the positive reinforcement is one of the key factors, making people use drugs. Pleasurable sensations, accruing after drug usage is the main reason of the desire to get drugs again and again. That is why, all people who are addicted to drugs, explain their addiction by this reason. The next motivation for the drug abuse is problems in the emotional life. When people have certain emotional or personal troubles, such as problems in family or relationships, they suppose that drugs are the only way out that can help them to escape from reality. The next point under discussion is drug addiction due to the inadequate personality. People, having the features of the inadequate personality experience low self-respect and feel constant failure of life. As a result they are more apt to become addicted to drugs. I can not agree more with this fact, as in our life there are quite many examples when individuals who are not satisfied with their life try to change this situation with the help of drugs. They think that only under the influence of drugs they can feel more self-confident and successful. The final topic of drug abuse reasons is unawareness of people about the negative effects of such addicting and absence of will power. In this case, the factor of negative reinforcement occurs. Very often, people, suffering from unbearable pains start using drugs in order to decrease pain and unpleasant feelings. They do it without complete understanding of the results, as the only motivation for them is pain relief. Weak will power or its complete absence is very significant factor that should be mentioned. People who are lack of will power have more chances to get into drug dependence. For such people it is very difficult to resist the temptation of drug usage, especially when they are influenced by the friends who are already abused by drugs.

Caffeine Typing Speed - Sample Science Fair Projects

Caffeine Typing Speed - Sample Science Fair Projects Purpose The purpose of this project is to determine whether taking caffeine affects typing speed. Hypothesis Typing speed is not affected by whether or not you take caffeine. (Remember: You cannot scientifically prove a hypothesis, however, you can disprove one.) Experiment Summary You are going to type the same text repeatedly for a specified length of time and compare how many words you typed before ingesting caffeine and afterward. Materials computera drink containing caffeine and another drink of the same type that does not contain caffeine (e.g., coffee and decaf coffee, diet cola and decaf diet cola)stopwatch or timer Experimental Procedure Drink the non-caffeinated beverage. Wait 30 minutes.Type The quick brown fox jumped over the lazy dog. as many times as you can for 2 minutes. If you can, type using a word processing program that keeps track of how many words you have entered.Drink the caffeinated beverage. Wait 30 minutes. (The peak effects from taking caffeine tend to be felt around 30-45 minutes after taking it.)Type The quick brown fox jumped over the lazy dog. as many times as you can for 2 minutes.Compare the number of words you typed. Calculate words per minute by dividing the total number of words that were typed by the number of minutes (e.g., 120 words in 2 minutes would be 60 words per minute).Repeat the experiment, preferably a total of at least three times. Data Construct a table stating the type of drink and the number of words you could type in 2 minutes.Calculate your average typing speed (words per minute) for each drink. Results Did taking caffeine affect how quickly you could type? If it did, did you type more or fewer words under the influence of caffeine? Conclusions Was your hypothesis accepted or rejected? Can you propose an explanation for the outcome?Do you think you would get the same results if you had tested the effects of the caffeinated beverage first? Caffeine stays in your system for a few hours. When it wears off, some people report feeling crashed instead of normal.How do you think the results would be affected by changing the amount of caffeine? What do you think would happen if you took too much caffeine?Do you think you became better at typing the test sentence over time?If your word processor can track typing errors, did you note any difference in the accuracy of your typing after drinking the caffeinated beverage? Could you propose a hypothesis about the effect of caffeine use on typing accuracy? Things to Think About Caffeine occurs naturally in over 50 different types of plants, including coffee beans, tea leaves, cocoa beans, and kola nuts.Caffeine acts as a mild stimulant. Some studies have shown that taking caffeine may temporarily increase concentration, reasoning, and memory. However, the effects of caffeine wear off after a few hours and if you routinely take caffeine you will need to take more to get the same effect.Most adults are exposed to caffeine in coffee and energy drinks. Children are likely to get caffeine from energy drinks, soft drinks, tea, and chocolate. Amount of Caffeine in Common Products Product Caffeine (mg) coffee (8 oz) 65 - 120 Red Bull (8.2 oz) 80 tea (8 oz) 20 - 90 cola (8 oz) 20 - 40 dark chocolate (1 oz) 5 - 40 milk chocolate (1 oz) 1 - 15 chocolate milk (8 oz) 2 - 7 decaf coffee (8 oz) 2 - 4
