Steinberg and summerfield have shown that CNS depressant drugs administered during learning reduce amount of acquisition that takes place and, many of the tranquilizers also have this effect. While as described earlier caffeine and amphetamine facilitate performance on learning and conditioning tasks and improve retention of recently memorized verbal material. In fact these effects can not be rigidly generalized. Several drugs acting on central nervous system are not classifiable as stimulant or depressant. The site drug or type of drug may on one occasion facilitate new learning, on another occasion retard it. In yet another circumstances, it may facilitate in a different way the retrieval of memories that have if any thing been too well stamped in. Outcome of the research being carried out to identify physiological and biochemical basis of memory will help drug design and the synthesis of compounds having pronounced effects on memory. That will considerably reduce the time spent on rote memorization. Thus leaving the educationist greater freedom to develop the more creative talents of his pupil, such developments in psychophermacology, combined with mechanical aid to teaching may well revolutionize the educational scene of tomorrow.
