Social interaction test
From 2021 to 2025, 482 animal research papers mentioned the social interaction test in their title or abstract, ranking it 28th of the 90 tests we track.
That is 1.5 times the 320 papers of 2011 to 2015. Papers that mention any of the 90 tests grew to 1.2 times as many over the same span.

Papers that mention the social interaction test fell from 98 in 2021 to 83 in 2023, then rose to 110 in 2025. Papers that PubMed indexed under the MeSH heading Animals also fell and rose, from 200,221 in 2021 to 156,447 in 2023 and 235,479 in 2025. We take each paper's species from PubMed's indexing whenever it names one, so part of this dip may come from the indexing rather than from fewer studies.

Which species the papers used
Each bar is a share of the 482 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 384 of the 482 papers, so each bar is a share of those 384.
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 social interaction test and study that disease model, with its share of the 482 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 social interaction test
Each bar counts the papers from 2021 to 2025 that mention both tests, with its share of the 482 papers that mention the social interaction test.

The most cited papers from 2021 to 2025
These papers from 2021 to 2025 mention the social interaction test and have the most citations, as counted by NIH's iCite on November 5, 2026. We show three of the five most cited papers and leave out two because of words in their titles.
Sci Total Environ, 2021. 74 citations.
Neuropharmacology, 2021. 58 citations.
Eur J Pharmacol, 2023. 53 citations.
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 social interaction test only in its methods is missed, so the count runs low. The count includes 20 reviews. For 98 of the 482 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.
