Q-S222 GSR Sensor
-
The Q-S222 GSR sensor monitors skin conductivity between two disposable tab electrodes attached to 2 fingers of one hand. While the subject is at rest, a steady background signal will be monitored by C901 LoggerPro software on the computer screen. The subject may then be stimulated in different ways and the degree of stimulation measured graphically.
The GSR sensor can be used in bio-feedback studies in which the subject learns to control emotional state voluntarily by using relaxation techniques. This is often done with closed eyes. The voltage signal declines as skin conductivity decreases with relaxation. The sensor must be used with C610 LabQuest Mini data interface and C901 Logger Pro sotware. Other data acquisitions interface that take 0-5V signal can also be used.
As well as relaxation studies, the S220 GSR sensor can also be used to determine the types of stimuli that excite various subjects. For example, the stimulatory or relaxing effect of different colors can be assessed, as well as the effects of various patterns and images.
