Caffeine Experiment Essay

1. To assess the effect of caffeine on persistence researchers assign their participants to a group that gets a non-caffeinated beverage or a group with a caffeinated beverage. They measure how much time the participants spend on a difficult puzzle.

An independent samples t-test was conducted to examine the difference between experimental conditions on test performance. The results indicated a significant difference between participants who consumed the caffeinated beverage and participants who did not, with participants in the caffeinated group (M = 7.64, SD = 2.41) performing worse than participants in the non-caffeinated group (M = 9.81, SD = 3.16), t (97) = 2.14, p < .05.

This article discusses the affects caffeine has on several aspects of human health. These included toxicity, cardiovascular effects (arrhythmia, heart rate, cholesterol and BP), bone/calcium balance, behavior, and reproductive and developmental effects. It also discussing the affect caffeine intake has on children and reproductive-aged women.

The problem of this research is to determine the effects of the caffeine to the babies and the abuse of the caffeine to the pregnant women. To know the things that the caffeine can do, we need to have a research about it. To know these, the researchers should work out to these following questions:

Have you ever drank a cola or any type of soda? Have you read or heard about the main ingredient including caffeine? Well caffeine is a bitter powder like substance that's very unhealthy and healthy in the same cause. Caffeine can lead to heart attacks but if taken in the right amount can help with long days at work.

Symptoms that follow caffeine consumption are: anxiety, panic attacks, increased heart palpitations, trembling, stress, heartburn, and the deprivation of sleep (Driedger, Doyle par 2). Over time these symptoms can become more severe and eventually will become a major disturbance in one’s life. The anxiety that comes from this can be especially harmful to those who suffer from anxiety disorders, such as GAD-General Anxiety Disorder and Panic Disorder as the caffeine can stimulate a panic attack (Human par 3). The most apparent concern of caffeine consumption, is its effects on teen life. Dr. Jim Lane, a researcher at Duke University stated, “Teens are chronically sleep deprived. Caffeine use might be a consequence of that, and also a cause. Drinking coffee could lead to sleep-onset insomnia, or a delay in going to bed, that contributes to sleep deprivation” (Teens par 7). This shows that as the caffeine trend among teens continue, the link to teen sleep deprivation strengthens. Not only does it prevent the continuation of sleep, but also the process of even falling asleep is delayed. The more deprived of sleep these

Or, those who have found that coffee is an applauded relief that just creates their day function that much smoother. Long hours at work, no problem; just have another cup to push one’s drained energy to Machiavellian those needed overtime hours. Adrenaline rush can be rightfully stimulating, especially if that artificial stimulating process happens rather quickly. All of a sudden, before one can blink an eye, the heterodox beliefs in caffeine have changed; the subtle slow addictive processes of caffeine use have taken hold. Addiction is addiction, it matters not the type of substance; the physical body has now become dependent upon an external source. A source, rest assured is not always readily available; Starbuck Coffee has never been heard of especially in third world countries. And of course, there is always the argument that stimulants such as these can come in all forms and readily available for emergency first response personnel. A quick energy reprieve just when they are in dire need, right? Besides, emergency response professionals need to be ready at all times; this believed in requirement continually encourages caffeine

Thesis: Caffeine can have many different effects on the body depending on the amount of consumption.

The purpose of my presentation is to inform my audience of the effects of caffeine, the conditions it can cause later on in their lives and knowledge to help them cut back on their consumption. For the audience of my presentation, I

The results of this is because of the existence of natural variation. Diverse individuals have different athletic skills, responsiveness to caffeine and gender differences that the sample sizes didn’t justify. The negligence to account for the essence of the sample sizes significantly decreases the reliability of the research. Males and females might have diverse reactions according to investigation (Kennedy MD, 2008), therefore require to be considered for independently. By splitting the caffeinated and decaffeinated into gender groups and possibly only studying its influence on athletes can advance the accuracy and reliability of this experiment.

Can someone tell me why they drink coffee? Well, most people think of it as a powerful drink that gives them energy whenever they need it. I am here to tell you that coffee works a lot differently than most of us think. It does something completely different than what you might expect to your body. And coffee is not the same for everyone, to some living things it’s even poisonous. Even its name is deceiving because coffee is not even a bean at all. I am not here to dissuade you from drinking coffee, but rather inform you about how coffee affects us and how our bodies deal with it. So next time when you chug down a cup you should know what you’re doing to your body.

One on the beneficial effects on caffeine, two the negative effects, and finally on trends in caffeine consumption

Specific Purpose: I want my audience to understand the positive and negative effects that caffeine has on a person.

Caffeine has many negative effects on humans, such as increased heart rate (Lane, J.D., 2002), depression (Goldstein, 2008), and addiction to this “drug.” You may be asking yourself, “What is caffeine?” Well, caffeine is actually a stimulant (Barone, Roberts, 2008) that is found in beverages such as tea, coffee, and soft drinks. In fact, caffeine is the highest grossing and most used stimulant in the United States (Barone, Roberts, 2008). It is estimated that 85% of adults living in the United States consume caffeine on a daily basis (Barone, Roberts, 2008). That means for every 100 adults, 85 of them have had a drink that contained caffeine on any given day. One reason caffeine is so widely available compared to other stimulants is

is derived from a bean or from tea leaves and can be found in the
