1. CAFFEINE’S EFFECT ON
MOTOR SKILLS

2. PREVIOUS STUDIES ON CAFFEINE AND MOTOR SKILLS
What are the negative effects of caffeine?
“A significantly poorer steadiness performance was found after ingestion of
300 mg of caffeine as compared to a placebo (de-caffeinated coffee).”
- Journal of Clinical and Experimental Neuropsychology
“In this study, we find that a moderate dose of caffeine impaired motor
sequence.”
- National Institute of Health Public Access

3. AFFECTED PARTS OF THE BRAIN

4. HYPOTHESIS
If drinking increased amount of caffeinated coffee will alter my brain function
by reducing my motor skills, then my scores and accuracy in White Tiles will
decrease.

8. TAKE HOME POINTS
1. Data suggests that caffeinated coffee impaired motor skills
2. Higher amounts of caffeinated coffee consumed resulted in lower scores

9. ANALYSIS
Additional Studies
- different types of caffeinated beverages
- how does caffeine effect memory or other
cognitive skills (i.e. problem solving)?
Limitations/assumptions
- time of day (evening/morning)
- improvement through practice

10. NEW QUESTIONS
How does caffeine effect the brain (i.e. cerebellum,
frontal lobe) on a biochemical level?
Does building up tolerance to caffeine by creating
more receptors on neurons, correlate with how the
cerebellum and frontal lobe are affected by
caffeine?
