Electrodermal Activity (EDA)/ Galvanic skin response (GSR) & the Polygraph

This BSL lesson demonstrates a number of important autonomic concepts and is a great introduction to EDA (a.k.a. GSR).

Students record the standard physiological measures of a polygraph and examine the effects of cognitive behavior and emotion. Students record changes in respiratory rate, heart rate and skin resistance. Each Subject answers a number of simple questions and watches a presentation to stimulate a response. It is possible to use a variety of different stimuli for the lesson.

The lesson is extremely flexible and allows the instructor to look at a variety of autonomic principles.

Experimental Objectives

  1. To become familiar with procedures for recording electrodermal activity.

  2. To observe and record the changes in respiratory rate, heart rate, and skin resistance associated with somatic and special sensory stimuli.

  3. To observe and record changes in respiratory rate, heart rate , and skin resistance associated with cognitive behavior and emotion.

  4. To analyze a 3-channel polygraph recording under various experimental conditions to gain a better understanding of polygraphy and its potential for use and misuse.

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.

Eye Tracking Glasses ETV

The ETVision (ETV) wearable unit resembles an eyeglasses frame that can be worn by itself or over the participant’s prescription eyeglasses. It contains miniature “eye cameras” that view each eye and a “scene camera” that views the scene in front of the participant, and a microphone. An optional visor can be mounted to the front […]
