我们评估了华盛顿大学婴儿灵长类动物研究实验室的辫子猕猴（Macaca nemestrina）的发育稳定性和气质的环境普遍性。主成分分析将 6 项行为指标浓缩为 2 个成分，解释为反应性和大胆性。在发育的前 10 个月中，这些指标的变化显示出随着年龄的增长，行为变得更加冷静和大胆的趋势，变化模式存在显着的个体差异。大胆度呈二次方变化模式，而反应性呈线性下降。我们还研究了气质和对新奇探针的反应之间的关系。随着时间的推移，对新奇事物的反应程度略有下降，而在熟悉的环境中的大胆和反应并不能预测这些对新奇事物的反应变化。在第二个主成分分析中，对新奇事物的反应性代表了气质的一个独特方面。我们的结果证明了猕猴行为的发育变化和环境依赖性。
We assessed developmental stability and context generalizability of temperament in pigtailed macaques (Macaca nemestrina) from the University of Washington Infant Primate Research Lab. A principal components analysis condensed 6 behavioral measures into 2 components, interpreted as reactivity and boldness. Changes in these measures over the 1st 10 months of development showed a trend toward calmer and bolder behavior with age, with significant individual variation in the pattern of change. Boldness showed a quadratic pattern of change, whereas reactivity decreased linearly. We also studied the relationship between temperament and response to a novelty probe. The magnitude of the response to the novelty probe decreased slightly over time, and boldness and reactivity in a familiar setting did not predict these changes in response to novelty. In a 2nd principal components analysis, reactivity to novelty represented a distinct aspect of temperament. Our results demonstrate developmental changes and context dependency in macaque behavior.
