Cheney and Seyfarth recorded one vervet monkey making a
call that indicates danger from another group of vervets
(wrrr)
• They played the wrrr call to the group, and group
began to ignore it
• They then played another call from the same monkey
which means more or less the same thing (chutter)
• The group immediately ignored that, suggesting that
they implicitly treated the particular calling monkey to
be unreliable at calling about approaching groups of
other monkeys
What control condition would need to be run to make sure thatthe vervets who ignored the wrrr and chutter calls treated the twocalls as referring to the same situation, vs. just treating theparticular monkey whose calls were being played as generallyunreliable?
would it be another group of monkey but under what setting sinceit's a control condition? Please help
