Positive Reinforcement Training (PRT) isn’t just a technique—it’s a relationship-building tool. When applied consistently and respectfully, PRT can reduce stress, encourage cooperation, and improve animal welfare outcomes. These simple guidelines help ensure safe, humane, and enriching interactions with nonhuman primates (NHPs).
Each step below represents a building block toward trust, collaboration, and success in PRT. Follow this positive path for effective, ethical training.
Find the Favorite
Identify a highly preferred food reward for each NHP.
Start strong—each animal has unique preferences. Whether it’s grapes, sunflower seeds, or dried mango, discovering the right reinforcer is the key to motivation.
Keep It Consistent
Use consistent cues and reinforcement timing.
Clear communication builds trust. Use the same verbal or visual cue for each behavior, and always deliver the reward promptly after the desired response.
Short and Sweet
Keep training sessions short: 5–10 minutes, 3–5 times weekly.
PRT is most effective in brief, focused sessions. Frequent short sessions prevent fatigue and keep animals engaged.
End on a High Note
Always end sessions with success or a high-value reward.
Even if the session is cut short, find a reason to celebrate. Finishing with a positive outcome reinforces trust and enthusiasm.
Volunteers Only
Avoid force or punishment—training should remain voluntary.
Respect the animal’s choice to participate. PRT thrives on cooperation, not coercion. If they’re not into it that day, try again tomorrow.
One Mark, One Reward
Maintain a 1:1 relationship between bridging stimulus and reinforcement.
Each click, whistle, or verbal bridge should result in one distinct reinforcement event. The amount of reinforcement can vary, but the pairing must stay consistent.
Never stop learning
Recognize that excellence in animal care is a journey. Remain open to new research, reflective about our practices, and humble in the face of evolving understanding. Seek feedback, mentorship, and growth — for the sake of the animals, the profession, and ourselves.
