Behavioral correlates of social dominance

The behavioral correlates of dominance in the squirrel monkey were explored using a variety of operant tasks. Compared to more submissive animals, more dominant ones showed higher operant rates, more consistent work output, and a higher degree of "frustration tolerance." These data suggest that dominance in the squirrel monkey is not related solely to physical size, but to a variety of behavioral traits which lead to more adjustive problem-solving behavior.
