Hmm.. IME the ability to move physical objects without physical means is usually called telekinesis. Raising BelDion's hand would be telekinesis.
Psychokinesis is a more general term, including TK in scope, but indicating more kinds of influence than just motion. Raising BelDion's hand, mentally affecting the output of a random number generator, or making someone's head explode would be examples of psychokinesis.
Psychokinesis is usually not considered as possible outside of the movies.
Your definitions may vary.
