Resident-intruder test
From 2021 to 2025, 134 animal research papers mentioned the resident-intruder test in their title or abstract, ranking it 50th of the 90 tests we track.
That is 6% fewer than the 142 papers of 2011 to 2015. Between the same two periods, all the animal research papers that mention any of the 90 tests we count rose 22%.

Which species the papers used
Each bar is a share of the 134 papers from 2021 to 2025. A paper can use more than one species, so the shares can add to more than 100%.
Species
“Other animals” counts papers that use none of the species this chart names.
Strains and genetic lines
Strain names come from the MeSH terms PubMed adds when it indexes a paper. PubMed has indexed 103 of the 134 papers, so each bar is a share of those 103.
A paper indexed under two of these headings, such as knockout mice and a strain, counts under both.
Disease models in papers that mention the resident-intruder test
Each bar is one disease model, with how many of the 134 papers from 2021 to 2025 that mention the resident-intruder test use it, and what share that is. The model comes from the paper's MeSH terms, the subject headings the National Library of Medicine adds when it indexes a paper. A paper without MeSH terms gets its model from PubTator 3, NCBI's text-mining service, if PubTator 3 finds the disease in the title or abstract. A paper can count under more than one model.
Papers from 2021 to 2025 by disease model
Tests mentioned alongside the resident-intruder test
Each bar is one test, with how many of the 134 papers from 2021 to 2025 that mention the resident-intruder test also mention it, and what share that is.
Papers from 2021 to 2025 that mention both tests
To count the papers that mention three or more tests together, start from the resident-intruder test in the test battery tool.
The most cited papers from 2021 to 2025

How we counted
A count is the number of animal research papers whose title or abstract mentions one of the test's search terms. It is not a count of experiments, labs or animals.
A paper that mentions the resident-intruder test only in its methods is missed, so the count runs low. The count includes 1 review. For 31 of the 134 papers, PubMed's indexing gave no species, so the species came from PubTator 3 finding one in the title or abstract.
The test's search terms are in the test list download. The full method, with each source and its terms of use, is on our main page, Behavioral tests in published research.
More social behavior tests
These social behavior tests also have a page, with their papers from 2021 to 2025. Each test with 30 or more papers gets one.
