Williams, Nicholas – Using strain gauges to measure post-active effects

A description of the experience
THE METAL-BENDERS by PROFESSOR JOHN B. HASTED
Resistive strain gauge experiments are necessary to the study of post-active effects. Suppose that a series of signals is obtained at a metal specimen, without visible deformation occurring. Will the signals continue if the subject departs from the sensor?
Several sessions with Nicholas Williams and Stephen North were deliberately interrupted in this way, but no significant signals have been recorded after the boy had accompanied me out of the room. No evidence for post-active signals was afforded.
On the basis of the foregoing discussion, l am unable to claim experimental evidence for a genuine paranormal post-active effect.
If metal-bending is supposed, as we think it is, to be a largely spontaneous phenomenon, then the whole concept of ‘post-action’ raises its value. [sic]
There is some evidence to show that when metal-bending is occurring, the subject’s electroencephalographic (EEG) signals are predominantly in the low frequency, alpha band, with possibly some delta and theta. But apart from this, there is typically little observable connection between the metal-bending action and the physiological functioning of the subject
