This study serves as a comparison study between the EPIC ClearView and a predicate device.

The EPIC ClearView is a galvanic skin response (GSR) measurement system that is intended to be used to determine autonomic response as psychological indicators by measuring the electrical resistance of the skin. The EPIC ClearView is a non-invasive digital bioelectrography instrument that is used to assess the electrophysiology of humans. The measurements are digital photographs taken in a brief exposure to an electric field. These measurements are quantified to produce a standardized Response Scale.

Inclusion Criteria:

• Sex: Male or Female.
• Age range: 18 to 85.

• Inability or unwillingness to provide informed consent.
• Subjects with pacemakers or another electrical device, such as an automatic internal cardiac defibrillator, implanted somewhere in their body.
• Subjects missing all or part of any of their fingers.
• Subjects with hand tremors or involuntary oscillations ("shaking") of the hands that prevent clear imaging.
