The Reaction Timer



1 - 999$59.99

Please Note: Requires a Muscle SpikerBox Pro and a USB connection to an Android device, Mac, or PC Desktop. Not compatible with iPhones or iPads.

The study of Reaction Time dates back to the mid-1800s, and is considered the beginning of cognitive neuroscience. Now you can participate in the ongoing history and study of how quick our brains can receive and send signals, with DIY tech that leverages the power of electrophysiology for precise measurements!

The Reaction Timer allows you to precisely quantify a person's reaction time by recording how quickly they can flex their muscles in response to a stimulus! Stimulate with two different colors of light in 3 different locations to test for visual reaction time. You can also test reactions to sound with the built-in speaker. Which will be faster? It is also possible to experiment with multiple stimuli at once for more complex experiments! The Reaction Timer will automatically insert a tick mark in line with your EMG recording for easy analysis.

Perfect for Project Lead The Way!

Project Lead The Way is an organization dedicated to providing engaging, hands-on STEM lessons for K-12 students. In their Human Body Systems lesson "2.2.4 Reaction Time," our Reaction Timer can be a great alternative to the recommended tools. This isn't just a computer game... Turn your Reaction Time lab into a quantitative, muscle physiology lab! You are in total control of the experimental variables. Compare sight, sound, decision making, and even different muscles. Does a muscle further away from the brain take longer to react? Your students can find out! To see just how simple it is to use, check out the How Fast can your Body React? experiment. Everything comes pre-assembled, and it pairs with our free, user-friendly software: Spike Recorder.
