清醒、行为正常的恒河猴被广泛用于神经生理学研究。神经信号通常是从经过操作性条件反射技术训练的猴子身上测量的，这些猴子执行各种行为任务以换取奖励。在过去的几年里，猴子在实验过程中的心理健康已成为越来越重要的关注点。我们提出了客观标准来探讨猴子在控制饮水量下连续多天工作的训练是否会影响它们的行为。为了这个目标，我们分析了几个月内广泛的物种特定行为（行为图），并使用这些行为图作为猴子福祉的代表。我们的结果表明，猴子在训练期间的行为不受训练期间无训练时间的影响。无论有多少天（两天或九天）随意供应食物和水的无训练天数，猴子在训练阶段在其家庭笼子里同样活跃和警觉。这表明猴子已经习惯了长时间的工作，并且在训练期间它们的健康得到了稳定的保证。
Awake, behaving rhesus monkeys are widely used in neurophysiological research. Neural signals are typically measured from monkeys trained with operant conditioning techniques to perform a variety of behavioral tasks in exchange for rewards. Over the past years, monkeys' psychological well-being during experimentation has become an increasingly important concern. We suggest objective criteria to explore whether training sessions during which the monkeys work under controlled water intake over many days might affect their behavior. With that aim, we analyzed a broad range of species-specific behaviors over several months (ethogram') and used these ethograms as a proxy for the monkeys' well-being. Our results show that monkeys' behavior during training sessions is unaffected by the duration of training-free days in-between. Independently of the number of training-free days (two or nine days) with ad libitum food and water supply, the monkeys were equally active and alert in their home group cages during training phases. This indicates that the monkeys were well habituated to prolonged working schedules and that their well-being was stably ensured during the training sessions.
