Background

The major purposes of the work done under this present grant were twofold: (a) to extend the Investigation begun by Dr. Dittborn of the relation between suggested sleep and hypnotizability as measured by standardized test procedures and assessed by clinical ratings , and (b) to familiarize Dr. Dittborn with procedures developed in our laboratory for the evaluation of hypnotizability with a view toward future research, taking advantage of the clinical facilities available to Dr. Dittborn in Chile. Further experience with experimental procedures formed an integral part of the second aim.

While the many similarities of interest between Dr. Dittborn and those at our laboratory initially suggested a program of research along broad lines in the areas of differing states of consciousness not primarily associated with hypnotic procedures, it soon became apparent that this would be less likely to result in specific experimental results than the planning of several studies designed to answer specific questions more limited in nature. These could then provide both substantive findings as steps for future research and Important methodological experience useful for the furtherance of that research.
