Psychokinesis
The ability to move objects at a distance by mental power.
The term has now largely displaced ‘‘telekinesis,’’ formerly
used by psychical researchers and Spiritualists. The term ‘‘psychokinesis’’
or ‘‘PK’’ was proposed by psychologist J. B. Rhine
and his associates at the Psychology Department, Duke University,
Durham, North Carolina, in 1934 in relation to experiments
with influencing the fall of dice by mental concentration.
Special terms have developed as the study of PK has expanded,
such as: ‘‘PK-MT’’ (psychokinetic effect on moving targets,
such as dice), ‘‘PK-LT’’ (influence on living target, such as
plants, healing, influencing of animals), and ‘‘PK-ST’’ (influence
on static targets). A ‘‘PK Placement Test’’ denotes a
PK-MT experiment in which the subject attempts to influence
falling objects to land in a designated area. (See also movement)
