ABSTRACT
In animal work, too, there have been many attempts to study rigid behaviour usually under the title “stereotyped” or “fixated” behaviour. The traits themselves are in turn, of course, based on empirical evidence of a similar kind; in other words, persons who behave in a sociable manner in one situation tend to behave in a sociable manner in other situations, and so forth. The picture that emerges from a great variety of different studies then is a fairly clear and concise one. The argument from correlations and factor analysis is possibly unlikely to satisfy biologists who tend to distrust complex statistical manipulations. Other difficulties are of a more technical kind, relating for instance to the structure of the transducer and its attachment to the organism. Until much more is known about the relationship between consolidation and personality, it will always be extremely difficult to predict the results of learning experiments and the relationship between learning, memory, and personality.
