图2 鼠类个性测量方法示意图。(A)旷场实验: 将实验场地分中心区(非安全区)和边缘区(安全区), 观察鼠类做出的不同行为以及在不同区域活动的时间, 主要测量鼠类勇敢性、活跃性和探索性; (B)出现实验: 在实验场地中放入一个庇护所, 观察鼠类从庇护所中出来的时间, 主要测量鼠类勇敢性; (C)洞板实验: 在实验场地中放入一块带有孔洞的塑料板, 观察鼠类将头伸入孔洞的次数和时间, 主要测量鼠类探索性。鼠类的图片引用自Gu et al, 2021。

Fig. 2 Schematic representation of the rodent personality measures. (A) Open-field test: The experimental field was divided into central area (non-safe area) and marginal area (safe area) to observe the different behaviors and the time of activity in different areas, mainly measuring the boldness, activity and exploration of rodents; (B) Emergence test: A shelter was placed in the experimental field to observe the latency to emerge of the rodents from the shelter, mainly measuring the boldness of rodents; (C) Hole-board test: A plastic plate with holes was placed in the experimental field to observe the number and time that the rodents had extended its head into the hole, mainly measuring the exploration of rodents.
