New methods for determining suggestibility

New method for determining suggestibility is described which elicits anesthesia in the finger tips by verbal suggestion. Suggestion is applied during simultaneous tapping and the effect is evaluated by feelings in the active hand or fingers (besides changes in feeling) and by motor disturbance (inhibition). The first results are reviewed which indicate that though the method has a relatively high threshold it can disclose also some intergroup differences. We believe that this is an objective method, its objectivity is primarily due to the fact that the investigated subject cannot anticipate what kind of result the suggestion is supposed to yield.
