Here is an extensive bibliography of Sony’s ESPER lab publications if you want to investigate further, but much of it is in Japanese. It’s possible some of the work may have been translated by now.
ESPER Laboratory*
The head of the laboratory is Yoichiro Sako. The Laboratory’s name means “Extra Sensory Perception & Excitation Research”. This Laboratory, part of SONY Corporation, was established in Tokyo in 1991 to study life phenomena, mental phenomena and anomalous phenomena. The final purpose of the laboratory as noted in the founding prospectus is to explore the mind/consciousness and spirit. 295) Before the ESPER Laboratory, there was a temporary laboratory called the “Human Science Research Institute” which existed for 6 months in 1990. There is a short report written in Spanish 296) about ESPER Laboratory.
Early work was on psi-conducive training with Japanese children. Researchers found that it was easy to develop psychic abilities by psi-conducive training. Some of these experiments were done on TV programs broadcasted by TBS. Psychic abilities of children were developed remarkably: for example, children could read letters without using their eyes; 281) and an anomalous connection of two paper clips was recorded by a video camera. 297)
Major results were published in Journal of Mind-Body Science 239-245) and Journal of International Society of Life Information Science 279-282) and a book. Workers presented their results at ISLIS, SMBS and the symposium on the Bi-Digital O-Ring Test.
