Some Basic Psi Test Procedures
THESE instructions follow the distinction between exploratory and conclusive methods made in Chapter 2. Each of these two broad stages of research naturally requires experimental procedures appropriate to it. This presentation of techniques takes for granted a general acquaintance with Part I of the book. Chapter 7 dealing with psychological conditions affecting psi is of special importance. A glossary of terms is given on pages 207- 210.
Four basic test procedures are described. They are the most widely used and will cover most of the needs the readers of this volume will likely have.

The procedures given are for tests of clairvoyance, of general extrasensory perception, of precognition, and of psychokinesis. They are described first in the form appropriate for exploratory experiments. Later, in a separate section, precautions required for conclusive experimentation are added for all four types of tests.
The aim is to present test instructions that will enable the student or professional worker to start his own experimenting in whatever general area of parapsychology or its application he may choose. As the experimenter continues to the point at which he may wish to know about other methods, he will already have become acquainted with research literature in which they are to be found.* He will have made the acquaintance of the Hum-____________________
