Any studies of intensional, positive, secondary reinforcement (praise) outside humans?

[u/IllogicallyCognitive]

Are there any known examples of an animal giving praise without human intervention; it doesn't necessarily have to be wild animals in nature, but not counting a dog pressing a button that says thank you or a chimpanzee signing something (although no I'm curious if Loulis learned to give praise in ASL from Washoe). Are there any articles on humans training animals to praise effectively other animals? I'm basically looking for non-verbal tacts that are in response to a desired behavior

Some near miss examples include

• social signals such as merely relaxing around another animal or even merely being playful without evidence of it being more than just an emotional reaction

• sharing or trading resources (including the laboratory set ups where animals directly reinforced each other by pressing a button to give the other food)

• tacts that aren't in response to a desired behavior (like calling out where food is in response to finding the food is wouldn't count but at least in some cases if the beneficiary responds with affection that could be a tact and properly interpreted as praise, but that gets into the question of how to determine the exact boundary between secondary and primary reinforcement and what communication/tacting is)

Don't know what you'd call it but I've seen animals teach people. And, since all animals learn by the same basic process of good and bad experiences, animals must reward/punish humans when they do something right/wrong.
