This document summarizes previous studies that found caffeine impaired motor skills. It describes an experiment that tested whether consuming increased amounts of caffeinated coffee would decrease scores on a motor skills test called White Tiles over 4 weeks. The results showed that higher amounts of caffeinated coffee consumed resulted in lower White Tiles scores, supporting the hypothesis that caffeine negatively impacts motor skills. The document raises questions about how caffeine biochemically affects the brain areas involved in motor control.
Why Does Coffee Improve Memory?

Everyone knows that coffee help us wake up in the morning and keeping during a long day. What is also the case is that coffee can help your memory. The easy part is that if you are more awake you will pay attention better and are more likely to remember things. But, does coffee help long term memory? Medical News Today comments on coffee and women’s risk of dementia.
Researchers have long suggested that caffeine - a mild stimulant present in coffee, tea, and cola - has cognitive benefits.
A study published in the journal Nature Neuroscience in 2014, for example, identified a link between coffee intake and improved long-term memory.
The new findings - recently published in The Journals of Gerontology, Series A: Biological Sciences and Medical Sciences - offer further evidence of caffeine's brain benefits, after finding the stimulant may help to stave off cognitive decline in later life.
Here is the older study first of all. The quoted article is from Nature Neuroscience, 17, 201-203 (2014) and is titled Post-study caffeine administration enhances memory consolidation in humans.
It is currently not known whether caffeine has an enhancing effect on long-term memory in humans. We used post-study caffeine administration to test its effect on memory consolidation using a behavioral discrimination task. Caffeine enhanced performance 24 h after administration according to an inverted U-shaped dose-response curve; this effect was specific to consolidation and not retrieval. We conclude that caffeine enhanced consolidation of long-term memories in humans.
So, there is measurable proof that long term memory is improved with coffee. What the later study reported in MNT shows is that long term coffee consumption is associated with a reduced risk of dementia.

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
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?
