During the session, an RNG (random number generator) determined when the sender was to concentrate and which type of target ("positive" or "neutral") was to be transmitted. The receiver was situated in a room 25 meters away. For each sending-period, the receiver tried to guess whether the emotional state of the sender was positive or neutral. At the same time, their Galvanic Skin Response (GSR) was monitored (like blood-pressure, GSR is known to relate to the general degree of emotional arousal).

When the results of the 32 different sender / receiver pairs were analyzed, Delanoy and Sah found null results for the receivers' conscious guesses as to the states of their senders. On the other hand, their electrodermal activity was significantly higher (p=.04) during the positive sending-periods than in the neutral periods - suggesting that they unconsciously did "pick up" the feeling-state of the sender.

In general, it seems that unconscious bodily reactions may be a more fruitful way for detecting psi than conscious guesses. In fact, "body psi" research suggests that, in day-to-day life, we may be receiving far more psi information than what surfaces into consciousness. The occasional spontaneous ESP experiences of which most of us are aware may be just the tip of the iceberg, a fraction of the psi information that circulates through the unconscious mind.
