A common factor in the MMPI scales of married couples.

Using canonical analysis, a common factor in the MMPI scales of husbands and wives was found. The Sc, Pd, and Hs scales for both the husbands and the wives contributed heavily to the relationship. Other scales contributing to the correlation between the personality components of the pairs were F, Hy Pt, and Si for the husbands and Pa for the wives. The results were interpreted as indicating areas of homogeneity and heterogeneity in the personalities of married couples.     

Simulation of neural sets

A program has been written for the PDP-8/I computer which simulates the behavior of 64 model neurons which may be connected together to form a functional neural net. The simulation includes provisions for studying the possible mechanisms of learning in real systems. Operation of the net requires inputs from either a robot or a robot simulator program and output from the net serves as input to such a robot, so that the entire system investigates the Behavior of an organism and its brain in interaction with an environment.
