Abstract: The arrangement of a social group of individuals into a dominance hierarchy is useful in studies of social behaviour only if a wide variety of social interactions can then be predicted. However, definitions of dominance commonly used are numerous and confused. To assess the usefulness of the concept of dominance, studies were made on six breeding groups of rhesus macaques (Macaca mulata) to determine whether different measures of dominance agreed with each other. The measures tested in this study were found to agree. It is therefore suggested that dominance is a useful intervening variable. Possible reasons for the reported lack of correlation between some measures used by other authors are discussed.

Syme, G. J. (1974). Competitive orders as measures of social dominance.22(Part 4), 931–940.
Abstract: The use of competitive orders as measures of social dominance is examined, the conclusion being that such use is based on the assumption of the unidimensionality of social dominance. Evidence is presented to show that this is not always the case. Consequently it is suggested that each competitive order must be validated in terms of its measurement of priority of access and response requirements (internal validity) as well as its generality (external validity) before it can be regarded as a dominance measure. Problems of the validity of aggression orders as measures of social dominance are also examined along with their relationship to competitive orders.
