=== Erectness of posture ===
Grade received after an exam influences erectness of posture (r = .6 to .8) and people intuitively infer dominance from erectness of posture. (Erectness before the exam does not affect the grade.)<ref>https://doi.org/10.1007/bf00992459</ref>

Ten months old toddlers are able to infer dominance relations between simple geometric objects by observing relative confidence and forcefulness in the object's movements.<ref>https://www.ncbi.nlm.nih.gov/pubmed/21273490</ref>

=== Eye contact ===
Another simple measure of dominance is the Visual Dominance Ratio defined as VDR = (% eye contact while speaking) / (% eye contact while listening).
 
Another simple dominance signal is eye contact. More dominant people keep eye contact when they speak, and more dominant people look away when someone else speaks.
 
This can be measured by the Visual Dominance Ratio defined as VDR = (% eye contact while speaking) / (% eye contact while listening).
Dominance positively correlates with eye contact during speaking and negatively with eye contact during listening.
Dominance positively correlates with eye contact during speaking and negatively with eye contact during listening.
The VDR cancels out differences in individual propensity for holding eye contact and combines both in one number.<ref>https://link.springer.com/chapter/10.1007/978-1-4684-2835-3_2</ref><ref>https://doi.org/10.2307/3033735</ref>
Dividing the two terms cancels out differences in individual propensity for holding eye contact and combines both in one number.<ref>https://books.google.com/books/about/Subliminal.html?id=V7wt3Sqj_X8C</ref>
