Cortisol (CORT) accumulates in the growing hair shaft of humans and nonhuman primates. We describe methods for extracting and analyzing hair CORT with high precision and sensitivity. Measurement of hair CORT is particularly well-suited for assessing chronic stress over periods of weeks to months.

Citations play a key role in academic writing by documenting the evidence that supports scholarly claims. Beyond giving credit to original authors, they show engagement with existing research and strengthen the credibility of an argument. Effective citation practices are central to research literacy because they reflect a writer’s ability to locate, evaluate, and integrate reliable sources into their work. Digital Tools for Citation Management Advances in digital technology have simplified the...
FAQs
Researchers examine the sequence and organization of actions, not only whether a monkey reaches a goal. Reaching, grasping, transporting, and manipulating an object provide observable measures of motor control, while successful physical problem-solving indicates how the animal adjusts behavior to task demands. Coding these actions separately helps relate movement patterns to flexible, goal-directed behavior.
Standardized tools and task conditions make behavioral observations more comparable across individuals and species. When animals encounter similar physical challenges, differences in reaching, grasping, transport, or object use can be interpreted in relation to motor abilities, problem-solving, and behavioral flexibility rather than uncontrolled changes in the task itself. This supports more systematic biological comparisons.
Performance in object-manipulation tasks can show how ecological pressures and cognitive abilities contribute to flexible behavior. If monkeys adapt their actions to obtain a goal, the behavior provides evidence about how they solve physical problems under particular conditions. Comparisons among species can then clarify whether differences in tool use relate to distinct ecological demands or cognitive capacities.
A study generally presents a monkey with a standardized tool or defined task condition, allows the relevant interaction to occur, and records the behavior through direct observation or video. Researchers then code actions such as reaching, grasping, transporting, and using an object to obtain a goal. The resulting behavioral record supports analysis of task performance and strategy.
Video-based coding preserves a record of how an animal approaches and manipulates an object, allowing researchers to analyze specific action sequences rather than relying only on overall success. It can capture reaching, grasping, transport, and object use in relation to the goal. This detailed record supports comparisons of motor control, problem-solving, and flexible behavior.
In biology, these studies connect observable object use with broader questions about social learning, problem-solving, and the evolutionary origins of tool use. Researchers can compare behavioral patterns among nonhuman primate species and examine how ecological pressures may shape them. The approach therefore links individual task performance with species-level and evolutionary interpretations of flexible behavior.
