摘要: We assessed developmental stability and context generalizability of temperament in pigtailed macaques (Macaca nemestrina) from the University Washington Infant Primate Research Lab. A principal components analysis condensed 6 behavioral measures into 2 components, interpreted as reactivity boldness. Changes these over 1st 10 months development showed a trend toward calmer bolder behavior with age, significant individual variation pattern change. Boldness quadratic change, whereas decreased linearly. also studied relationship between response to novelty probe. The magnitude probe slightly time, boldness familiar setting did not predict changes novelty. In 2nd analysis, represented distinct aspect temperament. Our results demonstrate dependency macaque behavior.
