Conditioned and unconditioned regulation of human activity

For development of a conditioned reflex it is necessary, that any factor of an environment, which may be perceived by one of analyzer systems of an organism, occur repeatedly and acted on an organism of the person or an animal. If at each occurrence this irritant outstrips a little or takes place ...
