It should be strongest between mother and small child. We would need some mothers, who do not know exactly why we are asking them to cooperate , to hold and stroke their children in a variety of ways, one of which is the method of stroking the neck. It is important that the mothers have NOT heard about the disputed reflex, as they may well communicate feelings of relaxation to the child unconsciously. If the initial results were favourable we would have to check it with a double blind system, to eliminate the possibility that those who are supervising the training of the mothers and assessing the results are themselves unconsciously biassing the results. As it is, the above induction MAY work by activating such a reflex, but it will be clear from my explanations that the preamble is powerfully involved in activating all sorts of mechanisms in the subject's mind.
Suggestion is very powerfully at work.
Activation of a child-adult relationship is there. Straining of the muscles of neck and eyes is there. All these will, we know, act to produce the result required. I knew, therefore, that it would work before ever trying it, whether or not the reflex is present. I know, furthermore, that if an audience has seen this method working on one subject, then they will be yet more inclined to follow suit.
