ABSTRACT:
There is provided a visual stimulation instrument operable to induce by perception of a visual message useful in therapeutic treatment of psychological and psychic disorders. A simple embodiment provides messages viewed by a patient with a sheet of paper comprising a viewing screen, with a lamp behind the paper flashed at high intensity during very short periodic intervals. One embodiment has two successive sheets of paper, one with an overt message and another with a covert message in such contrast that the lamp flash does not permit recognition of the covert message but does cause a conscious recognition of the overt message through the afterglow mechanism of the eye. The flashing by a gaseous discharge lamp preferably occurs periodically at a rate in the order of one to three seconds between flashes.
