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. Papers that mention any of the 90 tests rose 22% over the same span.

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 other species in this chart.
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 these papers study
Each bar counts the papers from 2021 to 2025 that mention the resident-intruder test and study that disease model, with its share of the 134 papers. The model comes from a paper's MeSH terms. For a paper PubMed has not indexed, it comes from PubTator 3, NCBI's text-mining service, when that service 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 counts the papers from 2021 to 2025 that mention both tests, with its share of the 134 papers that mention the resident-intruder test.

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.
