The 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> | 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> | ||

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. | ||
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> | |||
