In the USA, any institution involved in using non-human primates for research has had, for regulatory reasons, to address the psychological needs of these animals. Enriching the environment through the use of foraging devices has been one method and a study was designed to evaluate the short-term effect of a new foraging device on singly-housed cynomolgus monkeys. The study was divided into 3 one-week periods of observation: baseline, device filled with normal ration, and device filled with a novel food. Four behaviours were recorded: foraging, self-directed, hopper feeding, and other behaviours. During the observation periods the device was accepted in preference to the standard hopper style feeder and self-directed behaviours were significantly reduced compared with the baseline period. Changing to a novel food re-kindled interest in the device and reduced the extinguishing effect: i.e. decrease in interest or use of the device. Based on this study, the feeder has been included with several other devices in a rotation programme.
在美国，出于监管原因，任何使用非人类灵长类动物进行研究的机构都必须关注这些动物的心理需求。通过使用觅食装置丰富环境是一种方法，一项研究旨在评估一种新型觅食装置对单笼饲养的食蟹猴的短期影响。该研究分为3个为期一周的观察期：基线期、装有正常定量食物的装置期和装有新型食物的装置期。记录了四种行为：觅食、自我导向行为、料斗进食行为和其他行为。在观察期内，与标准料斗式喂食器相比，该装置更受青睐，并且与基线期相比，自我导向行为显著减少。更换为新型食物重新激发了对该装置的兴趣，并减少了消退效应，即对该装置兴趣或使用的减少。基于这项研究，该喂食器已与其他几种装置一起纳入了一个轮换计划。
