TL;DR

The interpretation of an invariant factor of mouse emotionality as “territorial marking” was tested and the interpretation of Factor 1, territorial marking, was borne out by the correlations with social measures.

Abstract

The interpretation of an invariant factor of mouse emotionality as “territorial marking” was tested. Ninety mice from two emotionally divergent strains, SJL/J and SWR/J, were obtained from the Jackson Laboratory. At 33 days of age, they were placed in separate cages and at 60 days of age they were run through a battery of tests consisting of 19 measures of emotionality. Scores were factor analyzed by alpha factoring, followed by varimax and then promax rotations. Factor scores were computed for all Ss on territorial marking and correlated with scores on nine tests of dominance and aggressiveness. The interpretation of Factor 1, territorial marking, was borne out by the correlations with social measures.

A number of general concepts are discussed, for example the relation of convulsions to flight behaviour, the reduction of incoming aggressive stimuli in submissive postures, "Cut-Off", and the inhibition of biting in the more social species.

It is suggested that there are two main Flight pathways, one leading to a Submissive Posture and the other to Crouch or Retreat, the occurrence of these is related to two types of behaviour seen in the wild, intra-colonial and territorial.

Observations confirm that social hierarchies develop in small colonies under certain conditions, but suggest that fighting tends to disperse the population into spatially distinct breeding areas initially occupied by one male and one or two females, i.e. that it is territorial in function.

Of the eight factors, motor discharge was most distinct in each population and tunneling-1 was least distinct, and eight of the resultant factors were found to be replicable across populations.
