on stimuli & response.

Vivian Cruz, Saskia Guerrier, Eurie Kim

Hypothesis
Distance affects response time: the farther away the stimuli, the slower the response.

Our story
There seems to be no correlation between the distance of the stimuli and the response time (nor in neural delay, nor in muscle delay).
However, we did discover that the neural delay times correspond to the response times because the neural (neurons being transmitted to the brain and back) process directly affects the physical reaction of the person.
Therefore, the faster the neural process, the faster the reaction.
The muscle delay did not correspond to the speeds of neural delays nor response times. Since muscle delay reflects the muscle movement, any muscle movement could have been picked up in the process of the person's thumb pressing the button (for instance, one could've just moved the thumb one time, but the next time one may have moved her wrist and thumb).
Thus, there is no correlation in distance of stimuli versus response time because regardless of where the stimuli is, the person will respond, BUT that response time will depend on CONCENTRATION more than distance.

This could mean that response and reflex is fundamentally different because response is controlled depending on one's concentration, while reflex is more an automatic response.

So what does the automatic-ness of one's reflex depend on?
