Caffeine increases the reaction time to visual and auditory stimuli
I belived that givng caffeine to a plant will cause i it to have no reaction to the caffeine

Stimulants (such as caffeine) can decrease reaction times by increasing alertness and speeding up cognitive processes. Depressants (such as alcohol) can impair reaction times by slowing down the central nervous system and affecting coordination and decision-making abilities. Both types of substances can have a significant impact on reaction times depending on the dose and individual tolerance.
"no it doesn't" Erm yes it does - that or the UK government has forced me to do a whole compulsory unit on the Nervous System and Caffeine etc. It's because caffeine is a stimulant. This stimulant stimulates the synapses - mean messages travel faster along the Central Nervous System. It also causes blood to pump faster around the body - allow more oxygen to get to muscles speeding up the body's working time in general. That's all I know...
it effects the nervous system in some cases making the body have spasms
Yes, mood can affect reaction time. Positive moods tend to improve reaction times, while negative moods can slow down reaction times. Emotions such as stress, anxiety, and anger can also impact reaction times negatively.
Caffeine can enhance alertness and focus, but it doesn't necessarily improve reaction time because the speed of a reaction depends on various factors, including neural processing speed and motor response. While caffeine may increase arousal and reduce fatigue, it doesn't directly accelerate the physiological processes involved in reaction times. Additionally, excessive caffeine can lead to jitteriness or anxiety, which may actually hinder performance. Thus, its effects on reaction time can be inconsistent and context-dependent.
Caffeine is a stimulant, which is the reason it could affect your typing speed.
A caffeine could possibly cause a rash, but only if you have some kind of allergic reaction to caffeine.
Man, I don't know!
Ot can temporarily slow them somewhat.
Caffeine does not affect how well birth control works. Thank goodness!
