The terms psycho-acoustics and psycho-optics were by now becoming fairly familiar and it was realised increasingly that the 'classical mechanistic approach' did not provide solutions to all the problems of electrical communication. As Dr Colin Cherry pointed out in an important article, that approach often ignores the real purpose, which is to transmit information from person to person. Chains of communication should sometimes be modified to suit psychological needs.
An exciting event was the reception at many places in Britain of signals from the 1-watt transmitter in the first of the Russian artificial satellites.
