COFFEE-PRESENTATION

Transcript: 90 Participants (In all) 30 Participants (Non-Coffee drinkers) 30 Participants (Light-Coffee drinkers) 30 Participants (Heavy-Coffee drinkers) THE 411 On COFFEE!! ages: 18-21 ALL GROUPS: 15 Female...15 Male Previous studies such as : The effect of caffeine on working memory load-related brain activation in middle-aged males shows very little or no effect of coffee on memory. Although many studies projects results which favor caffeine as a memory enhancer there is very little research on the role caffeine plays on sleep deprivation which in turn can cause memory loss. conclusion METHODS-PROCEDURE There is little to no study in this field and the ones that are, they focus on working memory instead Caffeine has become a daily part of 90% of American's life Consumption, and is consumed in one way or another. PREVIOUS STUDY HMMM...I WONDER..THAT'S what we WILL BE finding out! WHat Is Caffeine? OUR STUDY It is said to make a person calm, and helps to sharpen your mind and give you the strength to get through all-nighters (especially college students) Participants will be observe in their daily life in order to see what kind of drinkers they are. Another study done by Mitchell, Paula J., Monash U, Clayton, Vict, Australia Redman, and Jennifer R on Effects of caffeine, time of day and user history on study-related performance showed the effects of caffeine, time of day, and history of caffeine consumption on several study-related tasks in 25 undergraduates. Results showed that Reading comprehension was affected by time of day, while caffeine improved performance on all mental-speed-related tasks. High caffeine users performed more poorly than other groups on the verbal reasoning task. Several interactions between the 3 independent variables were observed on a number of tasks, supporting the notion that different processes underlying various types of cognitive performance are differentially, and often jointly, affected by caffeine, time of day, and user history. These studies prove that we are not certain of the effects of caffeine on sleep and memory, many studies shows that they help, many do not, the only way we can tell is by doing more research on its effect. Caffeine is a Bitter, White crystalline Xanthine that acts as a stimulant drug. both groups after they learn the passage will go back to their daily life STUDY ITSELF Heavy Coffee drinkers: Participants that consume 4 or more cups of coffee daily Participants that are chosen on the control side would be strictly non-coffee drinkers Does Coffee Impair long-term memory? The studies that were found said there had to be more done in order to see if there is an effect on long-term memory PROPOSAL PRESENTATION 3 weeks study The passage will be about a College students first day at school we will be recording how well the person recall the key words in the passage (For Example: The Professor's name, the floor the class is on, the time of the class..etc) DOES COFFEE CAUSE MEMORY IMPAIRMENT?
