Relationship between scores on Attentiveness and average attention span (regular participants) and the amount of time monkeys spent playing, vigilant, being groomed. Attentiveness scores have been scaled as T-scores (M = 50, SD = 10). Play, vigilant, and grooming behaviors are expressed as the percent of time focal individuals were engaged in each behavior. Scores on attention span were calculated for monkeys that participated on > 80% of cognitive testing sessions, and were scored according to whether participants exhibited high (“3”), medium (“2”), or low (“1”) attention during trials; scores were averaged across trials for each individual (see Methods).
