The placebo effect is an unacknowledged self-healing process that uses
mimicry, an instinctive, preverbal mechanism of the brain. This same
preverbal mimicry mechanism is involved in emotion, nonverbal communic
ation, the transitional object effect, empathy, and the esthetic respo
nse. Art therapy mobilizes the same nonspecific healing as does the pl
acebo effect because it assesses or explains the client's condition an
d involves a task that relies on the patient's involvement to perform.
It is possible to test whether specific art therapy techniques might
replace the mysterious placebo effect with a high rate of success and
predictability.
