L11A Reaction Time II – Visual Stimulus

BSL Visual Stimulus Reaction Time lab

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

Students see two presentation schedules of visual LED stimulation. The Subject presses a pushbutton hand switch as quickly as possible after seeing the LED blink.

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

Experimental Objectives

  1. Observe the effect of learning and the effect of anticipating the stimulus delivery on reaction time.
  2. Compare reaction times in four stimulus-response situations:
    a) Fixed interval stimulus presentation using the dominant hand for the response
    b) Random interval stimulus presentation using the dominant hand for the response.
    c) Fixed interval stimulus presentation using the nondominant hand for the response.
    d) Random interval stimulus presentation using the nondominant hand for the response.
  3. Compare the reaction times for groups of subjects by calculating the statistics of group mean, variance, and standard deviation in each of the four stimulus-response situations.
  4. Compare the visual stimulus reaction times to the auditory stimulus reaction times obtained in Lesson 11 (Reaction Time I).

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.
