摘要： 目的 ·探讨食蟹猴（ Macaca fascicularis）的自然抑郁模型是否与攻击 -屈服行为有关。方法 ·模拟野生环境，组建 2个食蟹猴群体（ G1和 G2），分别由 19和 14只食蟹猴个体组成。人为观察法记录 2个群体内攻击 -屈服行为的有效次数，分析并利用攻击 屈服行为矩阵，分别计算出每个个体在群体中 David得分（ Davids score，DS）。根据个体 DS得分的高低，将每个群体划分为攻击组和屈服组；焦点观察法记录个体 7个时段行为变化，并对所观察到的 11类行为进行统计分析。结果 ·组建群体后食蟹猴发生了较为激烈的冲突， 2个群体分别记录到 1 122和 1 409次攻击 -屈服行为。每个群体的攻击组和屈服组的日常行为分析结果显示， 2个群体的不同组别在焦虑行为（ t1 -4.053，P10.005；t2 -3.041；P20.012）、冲突行为（ t18.478，P10.018；t27.651；P20.002）、抑郁行为（ t1 -3.691，P10.006；t2 -2.431；P20.045）、运动行为（ t19.639，P10.007；t23.568；P20.002）上的差异均有统计学意义。结论 ·笼养食蟹猴的自然抑郁模型是一种由群体攻击 -屈服行为所引发的社会挫败模型。

Abstract:
Objective · To investigate the natural depression model of Macaca fascicularis inducedsubmissive-aggressive behaviors. Methods · In a simulated wild environment, two Macaca fascicularis groups (G1 and G2) were respectively established. The two groups consisted of 19 and 14 Macaca fascicularis respectively. The effective frequency of each groups submissive-aggressive behaviors was observed and recorded, the matrix of submissive-aggressive behaviors was analyzed, each individual of the group was calculated separatelyDavid’s score(DS), according to the level of individual DS, each group was divided into attack group and yield group; the behavior changes of each individual in 7 periods were recordedthe focus observation and the correlation analysis of 11 different behaviors was carried out. Results · After the formation of these groups, there was fierce conflict between the cynomolgus monkeys. 1 122 and 1 409 submissive-aggressive behaviors were recorded in the two groups respectively. In the submissive-aggressive behavior matrix, the differences between high and low DS in anxiety behavior (t1 -4.053, P10.005; t2 -3.041, P20.012), conflict behavior (t18.478, P10.018; t27.651, P20.002), depression behavior (t1 -3.691, P10.006; t2 -2.431, P20.045) and exercise behavior (t19.639, P10.007; t23.568; P20.002) were statistically significant. Conclusion · The natural depression model of caged Macaca fascicularis is a social defeat model inducedyield-attack behavior.
