Ecological validity of social interaction tests in rats and mice

Abstract

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.

TL;DR

This review argues that common laboratory tests of rat and mouse social behavior often have limited ecological validity because domestication, housing, and inbreeding can alter sociability, aggression, and dominance relative to wild conspecifics. It recommends improving ecological relevance while preserving controllability, especially for social fear-transmission paradigms and brain research.

Key findings

  • Domestication can rapidly change social behavior: after 42 generations of selection, Belyaev’s tame rat line scored 2.95 versus −2.9 for the aggressive line on a −5 to 5 tameness scale; tame rats also showed increased open-field locomotor activity and lower basal plasma corticosterone.
  • Wild and laboratory rats differ in aggression: wild-type Groningen rats included low (<15%), intermediate (15%–55%), and high (>55%) aggression subpopulations, whereas Wistar rats ranged from 0% to maximally 40% or 50% with no high-aggression animals.
  • Social dominance is measurable in both species but differs: wild rats form stable, linear hierarchies; laboratory rats show dominance partly attenuated by unlimited food, same-sex housing, simple environments, and domestication, with some studies reporting ~5%–35% of groups lacking clear ranks. Mice are more territorial, and laboratory mice often maintain hierarchy through serious aggression.
  • Social fear transmission is modeled as imminent threat, remote threat, and fear conditioning by proxy; observers show freezing, decreased heart rate, increased risk assessment, and acoustic startle, with fear conditioning by proxy producing moderate freezing that is significantly lower than direct fear conditioning.

Methods

  • Design: narrative review comparing laboratory and wild rats and mice as models for social behavior, with focus on social transmission of fear.
  • Data/sample: no primary empirical sample; synthesizes published studies on domestication, sociability, social dominance, and threat-information transmission, plus a comparison table of rats versus mice.
  • Main analysis: qualitative synthesis of behavioral paradigms and ecological validity, including discussion of Eco-HAB and other automated group-monitoring approaches.

Limitations

  • The paper states that knowledge of rat and mouse ecology, especially social life, is limited; reports on rodent social life are often contradictory and highly context-dependent, and complex paradigms can be hard to control and reproduce.
  • The paper states that achieving an optimal trade-off between ecological validity and usefulness for neuroscience will probably require multiple models with different levels of complexity.
  • Evident from the text: this is not a systematic review or meta-analysis, many cited wild-behavior studies are old (e.g., 1980s), some evidence is unpublished, and the authors note no study testing mice or rats’ social behaviors in field settings in the way done for other behaviors.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-09.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-09.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
