S11 Reaction Time

View Cart “Biopac Science Lab K-12 Stim-Response Systems” has been added to your cart.

The Reaction Time lesson demonstrates the effect of learning and physiological processes on reaction times. Students hear two presentation schedules of clicks through a set of headphones. With electrodes in place to record the activity of the extensor digitorum (the primary muscle used to lift a finger), the Subject lifts finger as quickly as possible after hearing a click. Students then perform a statistical analysis of the results, including: group mean, variance, and standard deviation.

Experimental Objectives

  1. Measure and compare reaction times of an individual subject using two stimulus presentation schedules: fixed intervals and pseudo-random intervals.
  2. Introduce elements of statistics into data analysis.
  3. Use statistics to determine the effects of learning on reaction times.
