Query: Cognitive ability experiment with photosensitive organic molecular thin
  films   We present an optical experiment which permits to evaluate the information
exchange necessary to self-induce cooperatively a well-organized pattern in a
randomly activated molecular assembly. A low-power coherent beam carrying
polarization and wavelength information is used to organize a surface relief
grating on a photochromic polymer thin film which is photo-activated by a
powerful incoherent beam. We demonstrate experimentally that less than 1% of
the molecules possessing information cooperatively transmit it to the entire
photo-activated polymer film.
