This is an indication that Chimpanzees can also display confidence whenever they are right!
Metacognitive monitoringbasically reflects a form of cognitive control which underlies the intelligent decision making capacity across various species.
Basically, metacognition happens when individuals monitor between what they know and what they do not know.
The research study comprised of three chimpanzees who were given a series of computerized tests to check their memory.
The study thus suggests that just like humans even chimpanzees have the capacity of metacognitive monitoring.
The details of the study and its results have been published in the journal,Cognition.
