What was played through the digital delay system, a Digitech RDS 7.6 with a continuously variable voltage control output, was the sounds of a clock, a Westclox Silver Bell Monogram, ticking, with the delay controlled by a galvanic skin response sensor ( GSR ).

Therefore, since one cannot reliably measure human emotions ( especially when one has an interest in hiding his / her emotions ), the idea of valid detection of truth or falsehood through measuring respiratory rate, blood volume, pulse rate and galvanic skin response is a mere pretense.

Galvanic skin response can be measured either as resistance, called skin resistance activity ( SRA ) or skin conductance activity ( SCA ), which is a reciprocal of SRA . Both SRA and SCA include two types of responses : the average level and the short-term phasic response.

Vilayanur S . Ramachandran explored the neural basis of the hyperreligiosity seen in TLE using the galvanic skin response ( GSR ), which correlates with emotional arousal, to determine whether the hyperreligiosity seen in TLE was due to an overall heightened emotional state or was specific to religious stimuli.

In 2007, a study at Iowa State University, the University of Michigan, and Vrije Universiteit by Nicholas L . Carnagey and colleagues found that participants who had previously played a violent video game had lower heart rate and galvanic skin response while viewing filmed real violence, demonstrating a physiological desensitization to violence.

Elliott began researching the relationship between and breathing and heart rate variability in the 2000 time frame, examining the correlation between breathing, heart rate, electroencephalography, and galvanic skin response with the finding that slow, deep, rhythmic breathing facilitated rapid changes in these measures, changes tending toward parasympathetic emphasis and the elicitation of the meditative state.
