Reflexes & Reaction Times

Explore reflexes in response to a variety of stimuli as well as changes in reaction time under a variety of conditions.

The aim of this experiment is for students to explore reflexes and reaction times. Students will examine a simple reflex by tapping the patellar tendon and complex reflexes in the muscles of the eye and muscles of the hand. Then students will examine which factors, such as distractions and predictability, increase and decrease reaction time. Students will also compare reaction times to visual and auditory cues. This experiment is suitable for students with basic knowledge of the PowerLab Data Acquisition System.
