Common term for a device known as an electropsychometer,
invented by Volney Mathison in the United States. It
measures galvanic skin response through changes in the electrical
conductivity of the skin when the subject is emotionally
aroused. The subject holds a handle in each hand, and strongly
emotive thoughts cause a meter needle to register a dramatic
change from zero. In the 1950s, the E-meter became an established
part of the procedures of Dianetics and Scientology.
Use of the E-meter by the members of the Church of Scientology
is explained in a series of books written by church founder
L. Ron Hubbard.
