Science Buddies: "Ask an Expert"

Hi! I'm looking to do a project to determine whether humans react faster to sight or sound. I need a journal article relating to this topic, but after rigourously searching the internet, I am still yet to find a free article. I'd appreciate any help finding an journal article. Thanks.

Hi,

Trying going to scholar.google.com and typing in "reaction time sight sound" several links come up that may be useful - I was able to access most articles for free.

Good Luck!

Hey!

Here are some sites that might be useful:

1. http://www.sciencenetlinks.com/lessons. ... 6&DocID=68 (similar experiment part 1)
2. http://www.sciencenetlinks.com/lessons.cfm?DocID=364 (similar experiment part 2)
3. http://webphysics.ph.msstate.edu/javami ... reflex.htm (check this site it is very interesting )

I hope this helps!

hey i remember doing a lab like this last year...here's how it went...

one person holds a yardstick vertically (with the 0 mark at the bottom) while the second person holds the yardstick between the thumb and second finger at the 0 inch mark (the end, basically)...the second person does not exactly grip the yardstick, so that if the first person lets go, the yardstick will fall through the second person's fingers.

The first part of the experiment is when the first person suddenly lets go of the stick, and as the second person watches, he or she will the grip the stick as quickly as possible...then they record how many inches passed before the second person reacted.

The second part is the same, except that the second person has to close his or her eyes, and the first person gives an auditory signal as to when the yardstick is being dropped.

You can then take an average of the lengths and see which one (auditory or sight) is faster...

I hope I helped a bit...
