H16 Reflexes & Reaction Time


This PRO Lesson describes basic reflex and reaction time (visual stimulus) exercises and details hardware and software setup of the BSL Lessons System to record reaction time to auditory stimulus. All data collection and analysis is done via the BIOPAC MP3x data acquisition unit and the Biopac Student Lab Lessons software.

Experimental Objectives

  1. Measure reflex response of the femoral, medial popliteal, musculocutaneous and radial nerves.
  2. Measure reaction time to visual stimulus.
  3. Observe the effects of learning and physiological processes on reaction times of auditory stimulus.
  4. Compare reaction times with two presentation schedules: fixed intervals and pseudo-random intervals of auditory stimulus.
  5. Design an experiment to determine factors that affect reaction time and indicate specifically where in the nervous system sequence a factor had its effect.
