TLDR
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.Abstract:
This paper describes elements in the social behaviour of the laboratory rat, mouse, hamster and Guinea-pig. These elements are divided into postures, which are static, and acts, which involve movement. A total of 45 of these elements are mentioned, most of which are common, with only slight modification, to all four species. Apart from these the guinea pig differs in not having a true Upright Posture and also in showing a male sexul display "Rumba". The postures are classified under broad motivational headings. 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.read more

Vocalization as an objective measure of shock-elicited social aggression in rats
TL;DR: In this paper, the authors compared the intensity of vocalizations emitted by pairs of shocked rats when physically separated by a transparent partition and when free to engage in social aggression and found that greater vocalization occurred in the free-access condition and was positively correlated with visually observed attack scores in pairs that had prior experience with shock.

Two types of chronic lead treatment in C57BL/6 mice: interaction with behavioural determinants of pain.
Colin Vickers,Anna T. Paterson +1 more
TL;DR: Lead-induced analgesia is discussed in terms of central mechanisms of pain reception, in which paw-lick and escape latencies were recorded and Escape latencies, with one exception, were longer in the Pb2 group than in thePb1 group.

Prior cocaine exposure in different environments affects the behavioral responses of mouse dams.
TL;DR: The present results suggest that the alterations in maternal behavior observed, as well as the trend underlined by oxytocin values, cannot be ascribed to carry-over effects of cocaine administration in the pre-mating phase per se; rather, they seem to represent a conditioned response to the distinct environment previously associated with the drug experience.

An analysis of the social behaviour of the male laboratory rat
TL;DR: 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.

An analysis of social behaviour in wild rats
TL;DR: A small number of experiments with R. rattus showed that this species possesses all the components of amicable and aggressive behaviour observed in R. norvegicus, but that it is less fierce and more agile.

Rank order in caged rats
E.C. Grant,M.R.A. Chance +1 more
TL;DR: Rank order was found to develop in cages containing 2, 3, 4 and 5 male rats but not in cagescontaining 6 male rats when assessed during the first three weeks after weaning, providing confirmatory evidence that the groups possess a stable structure.
