From local cafes and restaurants to school and fast food chains, the evidence is relative that coffee is truly everywhere in our society. One of coffees many uses was that it had the ability to make its consumers feel more ready to start the day. However, does caffeine really affect our moods and emotions? The aim of the following investigation is to discover how our emotional state changes when we have had a certain amount of caffeine, compared to when we are caffeine-free. The participants chosen for this experiment were South Australian, year 11 psychology students currently studying at Tension Woods College.

Hypothesis:

With greater caffeine intake there will be increase in energy and happier dispositions. This hypothesis will be proven by the mood questionnaire completed by students who have participated in the investigation.

Proposal: (Group Task)

The effects of caffeine on the body are amazing, as caffeine is a stimulant; it triggers a message similar to a stress reaction in our brain. The bodies’ central nervous system then recognizes the change in the messages sent from the brain, and creates biological changes in the body in relation to the messages, which hence alleviates fatigue and increases our rate of alertness and wakefulness, which can continue to influence your body’s state for a...

This was a breach of the ethical principal as it was a subtle form of coercion.

    A lot of people often wonder what caffeine is. When isolated in pure form, caffeine is a white crystalline powder that tastes very bitter. The chief source of pure caffeine is the process of decaffeinating coffee or tea. Caffeine is used to provide“boost energy” or a feeling of heightened alertness. It is often used to stay awake longer and late into the night. Many people feel as though they “cannot function” in the morning without a cup of coffee to provide caffeine and the boost it gives them. Caffeine is an addictive drug. It operates using the same mechanisms that amphetamines, cocaine, and heroin use to stimulate the brain. Caffeine effects are more mild than amphetamines, cocaine, and heroin, but it is manipulating the same channels, and that is one of the things that gives caffeine its addictive qualities. If you feel like you have to have caffeine everyday and cannot live without it, then you are considered addicted to caffeine.

In fact, coffee consumption among young adults rose to 3.2 cups per day in 2008 from 2.4 cups per day in 2005 (Rokerya 1). For instance, in a one hour period, on Richland College’s on-campus Starbucks, the author took note of how many customers arrived and purchased a cup of coffee. Between 8:00 and 9:00 AM, there were 51 customers, implying that – especially at college - many people are dependent on coffee in the mornings.
