The authors conducted experiments on 36 young males (average age 24 years0, who were all right-handed and in good health. Four experiments were done. There was a spatial recognition task, a verbal item recognition task, a spatial compatibility test (SPAT), and a spatial compatibility test (SIMON). Each test involved using the left or right hand for different responses. The tests activated different sides of the brain. While doing the tests, the subjects wore two cell phones, one strapped to each side of the head. The RFR was at 890.2 MHz, pulsed, with peak power 2 W, and average power 0.25 W. The phones were battery operated, and the communication between the phones and the test system was wireless. The students did all the tests at two sessions, separated by a 5 minute rest. In each session one phone was activated at a time and they also had a sham exposure. The subjects were unaware of the exposure status. The examiner was separated from the subject by an opaque partition. The order of exposure and the order of the tasks were counterbalanced.

In three of the tasks the exposure of the left side of the brain was associated with slowing of the left-hand response time. This effect was significant only in the spatial recognition task. In the exposures to the right hemisphere this effect was not seen, and in general the reaction times decreased between the first and second tests, presumably because of a training effect.
