An experiment sought to compare dominance manifested in water competition under two levels of deprivation, with grooming activity in a non-deprived state. While competitive dominance was significantly related to motivational level, grooming emerged as a more stable indicator of social ascendance, and did not require prior manipulation of a biological state. The implications of this observation for broader aspects of social motivation arc discussed.
