Discover how skin conductance, heart rate, and respiratory rate can be altered using the principles of classical conditioning. The aim of this experiment is for students to learn the principles of classical conditioning in conjunction with psychophysiological measurements. Students will use skin conductance, heart rate, and respiratory rate to determine if a naïve volunteer can be conditioned to be nervous of a neutral stimulus. Students will then compare the difference in these measurements for an aware volunteer and measure the latency of the skin conductance response. This experiment can follow “Electrodermal Response (EDR)” or be used on its own. It is suitable for students with basic knowledge of the PowerLab Data Acquisition System.
