More than thirty years of research has demonstrated rather conclusively that the average human being when connected to a galvanic skin response detection device (generic name for a Hubbard Electro-psychometer) routinely registers presentiment of about five seconds. That is, the meter reads on average 5 second prior to the subject being provided with a concept to respond to. This research has been performed on people taken off the street, with no previous psychic or spiritual training or study. It has been conducted applying exacting scientific standards.
What do you reckon the implications of these findings are to someone who has received hundreds of hours of standard Scientology auditing? That is, a process in which the practitioner is only permitted to address those concepts or incidents that react on the meter only at the precise end of the major thought as expressed in words by the auditor.
A few books off the top of my head where the referred to research is discussed:
The Field by Linda McTaggart
The Intention Experiment by Linda McTaggart
The End of Suffering by Russell Targ and J.J. Hurtak
Entangled Minds by Dean Radin
