At 1 year and 2.5 years of age, rhesus monkeys were removed from the colony to a strange situation. Upon introduction, each monkey was watched for 2 hr, given a series of behavioural tests, and watched again six days after introduction. Activity increased with age, as did readiness to approach a ball. Time spent looking at a mirror decreased with age. Although test measures were reliable at each age, there was no significantly positive correlation from one age to the next. Nevertheless, with mal...

Abstract When one-year old rhesus monkeys and their mothers were removed from the colony to a strange situation, infants' activity was initially low compared with behaviour six days later. Although absolute values did not differ between males and females, correlations did. That is, three days after return to the colony, correlations with baseline colony behaviour were significantly positive for females, while males had one significantly negative correlation. On the other hand, males had more sig...

Using behaviourally-defined adjectives and a 7-point scale, observers rated all individuals over a year old in a colony of rhesus monkeys every November for four years. Principal component analyses of the ratings provided a basis for the following scores each year: CONFIDENT, EXCITABLE, and SOCIABLE. Two- and three-year old females had higher EXCITABLE scores than males, and adult males were more CONFIDENT than adult females. At all ages, CONFIDENT scores were stable from year to year, whereas E...
