L11 Reaction Time I – Auditory Stimulus

Reaction time lesson

The lesson demonstrates the effect of learning and physiological processes on reaction times to an auditory stimulus.

Students hear two presentation schedules of clicks through a set of headphones. The Subject presses a pushbutton hand switch as quickly as possible after hearing the click.

Students can then perform a statistical analysis of the results including: group mean, variance and standard deviation.

Experimental Objectives

  1. Observe the effects of learning and physiological processes on reaction times.

  2. Compare reaction times with two presentation schedules: fixed intervals and random intervals.

  3. Calculate statistics of group mean, variance, and standard deviation.

Tasks Performed by the Student

BSL Lessons are designed to allow at least four students to record and save data in a normal lab period (60-90 minutes). Typically, labs work most efficiently with three or more students working together at each BSL station.

Add active learning segments designed by students or instructor to expand this lesson.
