“…Since it was also less clearly restricted to dominant animals, it did not represent a genuine attack strategy (Blanchard, Takahashi, & Blanchard, 1977). Significant correlations have been shown to exist between boxing and fighting in Wistar rats (Drews & Wulczyn, 1975;Spigel & Fraser, 1974). Only in this rat strain could we confirm this result (Militzer & Reinhard, 1979a).…”

“…On the other hand, they were either oppositely orientated (Factor IV, ADI vs. wins in runway test) or methodologically dependent on one another (Factor V. drinking time and rank index). Other authors have also assigned the different parameters of rivalry in rats to various factors (Drews & Dickey, 1977;Drews & Wulczyn, 1975), or significant correlations were missing (Baenninger, 1970;Gartner , Wankel, & Gaudszuhn, 1981;Howells & Kise, 1974). We must thus assume that only relative rank orders for the various types of competition and rivalry in male rats exist (Bernstein, 1981;Tembrock, Note 1).…”

Spontaneous behavioral categories such as attack. submission. boxing. allogrooming, mounting. and anogenital control were investigated in nine groups of three rats each. At the same time. the number of wins in the runway test and the amount of time spent occupying access-to-water space were registered in competitive tests. Antagonistic behavior jattack and induction of submission) permitted no significant relationships to be drawn as to the results of the competitive tests. The competitive parameters. too. showed no correlation among themselves. In agreement with other authors. we reject the existence of an encompassing unidimensional rank order in rats on the basis of these results. Attack wins and induction of submission showed a positive correlation to one another as well as to relative thymus and testes weights. A high antagonistic activity was also correlated with low relative adrenal weight. large number of nuclei in the adrenal cortex. and wide tubuli seminiferi in the testes. As indicated by factor analysis. a significant decrease in body weight. low heart. thymus. liver. spleen. kidney. and testes weights. and high adrenal weight with decreased number of nuclei in the adrenal cortex were typical for rats with low aggressive rank positions. The influence of endocrine organs and diminished physical vitality in these low-ranking animals was also observed following nonsocial stress.

“…Together with rats' ability to rapidly read cues about other's social rank, it implies that fights are rare events within established dominance structures . This problem could be potentially resolved by measuring competition for rewards, but that is not always a reliable indicator of dominance in laboratory rats . Secondly, literature suggests that dominance hierarchies are generally less pronounced among domesticated rats than in the wild.…”

Different rat and mouse models are used in studies of social interactions. Simple behavioral measures, which are commonly used in the laboratory, allow to perform relatively short experiments and to use multiple brain manipulation techniques. However, too much focus on the simplest behavioral models generates a serious risk of reducing ecological validity or even studying phenomena which would never happen outside of the laboratory. In this review, we discuss the suitability of mice and rats as model organisms for studying social behaviors, with focus on social transmission of fear paradigms. First, we briefly introduce the concept of domestication and what impact it had on laboratory rodents. Then, we present two aspects of social behaviors, sociability and dominance, which are crucial for social organization in these species. Finally, we present experimental models used for studying how animals transmit information about danger between each other, and how these models may reflect what happens in the natural environment. We discuss the difficulties that arise from our limited knowledge of rat and mouse ecology, especially their social life. We also explore the subject of balancing ecological validity and controllability in rodent models of social behaviors, the latter being particularly important for studying brain activity. Although it is very challenging, an efficient program for social neuroscience research should, in our opinion, aim at bridging the gap between laboratory and field studies.

“…Defmitions for these behaviors, excepting wrestle and threat, may be found in Drews and Wulczyn (1975). Wrestling resembles fighting, but lacks biting and audible vocalization.…”

The social interactions of three family groups of rats (Rattus norvegicus) were observed daily when the litters were 25-32, 60-67, and 79-86 days old. In contrast to similar recent studies, fathers were present in these families. The data were analyzed to isolate the development of patterns of behavior specific to different age-sex classes. These data indicate frequent interactions between adult males and their young and suggest that the role of adult males in socialization of young deserves further attention.
