The actual learning problems for the rats involved both maze learning and Skinner-box situations. In both studies, Es believing their Ss to be bred for brightness obtained better learning from their rats than did Es believing their Ss to have been bred for dullness (ps were 01 and.02).

work with planaria by Janmes McCon-nell and others at the University of Michigan. McConnell taught flatwormls to associate light with shock and re-ported that he was able to transfer this learning to other flatworms by feeding thenm cut-up portions of trained worms. When D. Ewen Cameron of Montreal reported that RNA extracted from yeast seemed to improve memory in


of remote control stimulation a certain area in his brain. Untrained planaria may correctly go through a maze when fed RNA from planaria which have been trained. Such psychological research which deals with the origins of behavior is being carĀ­ ried out on a wide front and may eventually bring new insights into alcoholic drinking,

RNA and Memory: From Feeding to Dispatch Localization

The history of ideas on the role of RNA in learning and memory is colorful. In the early 1960s, when RNA was the newly proclaimed carrier of genetic information, an ad-man turned psychologist, James V. McConnell, reported experiments on planaria claiming that memory could be transferred from trained to untrained individu-als directly through RNA [1].

were reported for i8 experiments with Planaria dorotocephala, a flatworm (RICE and LAWLESS, I957). The experiments with planarian flatworms differed from the studies with paramecia and mealworms in that thigmotropic influence was controlled by discarding data from animals which guided along the edge of the maze.
