It has major evaluative reviews of spontaneous cases and of psychic healing; methodological articles on enhancing PK test
performance and on testing children; and incisive reflections on conjurers' relations to psychical research.
The subject's effort would not have to act into the past because the decision on the outcome would not yet be made until the subject received feedback during the PK test session.
For a PK test run, the next unused bits were accessed consecutively with a continuous display of the subject's performance at the moment.
In the subsequent PK test sessions, the subject follows for each test run the independent observer's assignments, aiming for an excess of red or green signals, respectively.
Most of the subjects were not aware that this was a PK test with prerecorded events, because it looked like an ordinary PK test in which the subject tries to affect the display in a certain manner and receives a success score at the end of a run.
The data were gathered with a small self-recording PK test machine that could be mailed to the participants with detailed test instructions.
For each of the two identical test machines used in this experiment, 10 blocks of 10,000 binary events were generated and recorded before the PK test sessions, and another 10 blocks of 10,000 binary events after the completion of the sessions.
At the time I was completing my PhD at the University of Edinburgh, and, in a separate project, I had just finished work on a computerized PK test
in the form of a game that was loosely based on trading futures contracts on an imaginary commodity market.

Conscious concentration and visualization in PK tests
Another positive aspect of the book is that it provides the reader with useful information about experimental research, such as the chapter on ESP and PK tests
