Past research found that the early studies on the effects of caffeine on cognitive performance were often too small to detect general group effects (Smit & Rogers, 2000). This study will utilize college students, both undergraduate and graduate, to broaden the study. It was also found that caffeine consumption may be correlated with the amount of hours of sleep people get each night, which may also influence students’ academic achievement (Smit & Rogers, 2000). High doses of caffeine in the late evening increases the time taken for some individuals to go to sleep, which also results in fewer sleeping hours. The effects of caffeine on sleep can vary from individual to individual, and even when sleep is affected there is no clear evidence
Planaria are commonly known as flatworms. These flatworms have sensory organs which allow them to detect light using eyespots (Planaria,2017). The eyespots contain receptors that are highly sensitive to light stimuli causing planaria to prefer darkness. Planaria do not have lungs nor gills. Oxygen enters their bodies through membrane diffusion. Although planaria are just worms, their body react very similar to that of humans when injected with certain drugs or stimulants. One overused and highly popular stimulant is caffeine. Caffeine is known to increase individual’s energy and physical activity which makes them more alert of the surroundings. This observation leads to the question of how different concentrations of caffeine would affect planaria’s
The objective of this experiment was to perform extraction. This is a separation and purification technique, based on different solubility of compounds in immiscible solvent mixtures. Extraction is conducted by shaking the solution with the solvent, until two layers are formed. One layer can then be separated from the other. If the separation does not happen in one try, multiple attempts may be needed.
Caffeine, a central nervous system stimulant, is the main psychoactive ingredient in energy drinks, which enhances alertness and mood, and counteracts symptoms of sleep. There is no doubt ...

The Effects of Levels of Processing on Memory PB1: Identify the aim of the research and state the experimental/alternative hypothesis/es. (credited in the report mark scheme) To show how different levels of processing affects the memory. “People who process information deeply (i.e. semantic processing) tend to remember more than those who process information shallowly (i.e. visual processing). ” PB2: Explain why a directional or non-directional experimental/alternative hypothesis/es has been selected. (I mark) I have used a directional experimental hypothesis because past research, such as that by Craik and Tulving (1975) has proved this. PB3:
Caffeine Effects In The Brain Caffeine acts in a multitude of ways in the brain. The most recent studies explore the cooperative effects of adenosine and dopamine, as well as the increase in calcium in the interstitial fluid and possible accumulation of cyclic adenosine monophospate. The most popular discussions of earlier studies of caffeine demonstrate its antagonistic effects on adenosine receptors. While it has been reported that adenosine receptors are located throughout the brain, the various subtypes can be found in very specific areas. Studies have also shown that caffeine reactions in the brain are based on the localization of adenosine receptors, dopamine receptors, and the amount of caffeine.
If all of these important activities occur during sleep, why is it that people are so willing to short themselves of this vital activity? Although much about sleep still remains a mystery, research and experiments continue to show how important sleep is to each and every person. Throughout this paper, I will discuss sleep and the effects that it has on performance and health, especially among college students. A college student’s sleeping pattern is a reliable indicator of their level of performance in the classroom and other school-affiliated activities, as a lack of sleep leads to decreased performance. Sleep is directly related to the level of performance and health of an individual; the more rested a person is, the better that person will perform and feel (Dryer, 2006).
However, adverse effects of excessive caffeine on mental health have been reported as well. Higher levels of anxiety were described in moderate to high caffeine consumers paralleled with students who used no caffeine at all. Anxiety stemming from caffeine use, was found more commonly in the male participants than females, however both exhibited depressive
As the vast majority of Americans are addicted to caffeine, studies show that the effects during post-consumption, can be positive or negative depending on the amount and frequency of caffeine intake. As the demand for caffeine has increased, the caffeine industry has increased its amount of marketing and establishments to help aid this demand. Caffeine addiction can lead to serious health detriments and physiological detriments. It is evident that the primary reason for consumption of caffeinated beverages is due to positive effects, such as alertness. The media has an abundance of marketing to continue to illustrate this main effect. The media fails to project the negative effects of excessive caffeine intake. This literature review will illustrate how excessive caffeine consumption can be detrimental to one’s life, and how problematic caffeine use derives from conditioning by the caffeine industries.
Sleep deprivation, and irregular sleep schedules are particularly common among college students. This is usually common when students decide to start study or do their homework the night before it is due. If losing sleep continues on over a long time it leaves many negative impacts on one’s brain, academic performance, and health. The result of sleep deprivation leaves many negative impacts on one’s brain, academic performance, and health. Studies have shown that the sleep loss results in brain damage. In addition to brain damage there comes the negative outcome such as having hallucinations, seizures, and the Alzheimer’s disease. There also seems to be a significant decrease on the students’ academic performance. Not having the right
Open with Impact: How much coffee do you drink? How is that cup of coffee affecting your brain, thinking skills, alertness, sleep, and overall health?
The aim of this study was to determine the relationship between breakfast and undergraduate academic performance. This study conducted based on the previous research that only concerning on school students, but little research has been done on college students. Fifty two undergraduate students from International Islamic University Malaysia were responded to and completed a web- based survey. Questionnaires in the survey were adapted from Staub (2000). Participants had to rate their academic performance in a particular area such alertness, participation, attention, mood, taking note and the level of anxiety before test. The survey also asked the Cumulative Grade Point Average to find the correlation between breakfast and academic achievement of students. The results found that breakfast eater correlated with mood and note taking in the class and students who took breakfast more likely to have good rate in CGPA. SPSS have been used to analyze the result. The result suggested that, breakfast may be considered as healthy life style and it can be platform to help students in maintaining their learning strategies.
As side from that, excess caffeine can also overstimulate the central nervous system, disrupting sleeping patterns. High amounts of caffeine produce negative effect on sleep onset and quality. However, there are large individual differences in the effects of caffeine on sleep. Many people consume coffee during the evening and have no problems falling asleep, while others find that the mild stimulation of caffeine consumed shortly before a bed time delays the time to fall asleep.

...st year college GPAs and eating breakfast. However, the relationship between not eating breakfast and higher GPAs could have been a collinear relation to sleeping-habit factors, since those who woke up earlier have a better chance of eating breakfast. After controlling the effects of weekend and weekday wake up time, the study demonstrated that eating breakfast did not significantly affect the GPA. However, eating breakfast did prove to improve real and spatial memory among the students. No other nutritional-related variable had a significant effect on student GPA.
