Suggestibility

A major parameter of Suggestibility in this context, is a measure of our familiarity  with abstract thinking, that is the ability or tendency to experience absorption or concentration on inner experiences such as thought, imagination or fantasy.  This line of research produced the Tellegen Absorption Scale (1974), which was devised to measure "an openness to self altering experience". On this view a concrete and unimaginative individual is unlikely to experience subtle variations of inner states very clearly and will not appreciate abstract ideas as readily, but these abilities can develop with practice (see Part 1.3 Attention and Relaxation).

The suggestibility tests give the opportunity to evaluate the client and determine the most appropriate style of induction to use. Certain types of Clients will respond well to a commanding style but not everyone likes being told what to do! In fact some "Polarity Responders" enjoy doing the opposite. Some of these Clients may also feel that compliance is a sign of weakness of will, and may actually be proud of the fact that they cannot be Hypnotised (see Ericksons "As If" approach, Part.2.1)

Once the Cx is reasonably comfortable about control issues we can begin to discuss suggestibility. Once again the task is to gently extend the Cx's comfort zone by building up familiarity and confidence (preconditioning) in both the therapist and in Hypnotherapy.

The simplest test of suggestibility, which can even be done over the phone, is the "Arms Raising and Falling" test, which it a particularly good way to evaluate the strength of the Cx's imagination. It is a permissive test (as opposed to authoritative), where the Cx is encouraged to imagine a Helium balloon in one outstretched hand and a heavy book in the other. If the arms move gently upwards/downwards in response to the two suggestions you have a positive result. If there is no movement there is resistance which indicates a reluctance to give up control (GoTo Part.1.3.Responsiveness).

If the Cx doesn't respond to the permissive type of test it is worth trying an authoritative type test such as the "Hand Clasp" test. Here the Cx is asked to lock hands in front and imagine they are stuck like glue. The script becomes more authoritative as it proceeds, until the therapist asks the Cx to pull them apart ... if it has worked people will find if quite difficult to separate their hands. There is also a permissive version of this test.

Other tests include:

• Chevreul's Pendulum (tests concentration - permissive type).
• Postural Sway Test (tests trust - authoritative type).
