But much like humans, both species showed negative emotional responses when waiting for a bigger reward, scratching themselves and banging the table and mesh.Ĭhimpanzees also screamed and whimpered and moaned on about half of the trials, whereas bonobos were quieter and vocalised on only 5% of trials. Neither species showed signs of being frustrated or annoyed when the small reward was received straight away. In the “Temporal Preference” study, each ape could either choose a small reward (a piece of food) and receive it straightaway, or choose a big reward (three pieces of food) but have to wait for either one or two minutes to receive it. The participants indicated their choice by pointing at one of two options (one piece of food on the left to be received straight away or three pieces of food on the right to be received after one or two minutes). Each ape was tested separately, sitting at a table with a sliding top across from the experimenter, but separated by wire mesh. The 23 chimpanzees (ranging in age from 7-20 years) and 15 bonobos (ranging in age from 7-10 years) took part in two different tasks: a temporal task and risk “preference” task. Non-invasive cognitive-behavioural studies such as this one provide us with the opportunity to find out more about how wild-born, semi-free-ranging apes solve problems and “think”, while at the same time allowing these intelligent beings the chance to take part in tasks that they find fun, stimulating and enriching. The PLoS ONE study took place at two sanctuaries in the Republic of Congo – Tchimpounga Chimpanzee Sanctuary in Pointe Noire and Lola ya Bonobo Sanctuary in Kinshasa – both of which care for confiscated apes mostly orphaned as a result of the illegal bushmeat trade.Ī bonobo baby … surely a tantrum would be justified? James Hopkirk How do our hairy relatives respond to waiting for a treat or risky choices? taking a risk with a 50/50 chance of getting a “good” or “bad” food reward rather than the safe option of a reward that was neither liked nor disliked.being patient and waiting to get a bigger reward.Rosati and Hare were interested in whether those emotional responses would appear in two studies in which chimpanzees and bonobos had to make an “economic” decision, which involved: scratching the head or body) and, as they become more cross or angry, they hit, bang or bash things with their hands or feet. ![]() They may pull a pouty face and whimper or moan, show displacement behaviours (e.g. If chimpanzees and bonobos want something from a friend or relative or human care-giver, and the other ape is taking too long to respond or denying them their treat, they start to show frustration, impatience or annoyance in ways that are very recognisable to humans.Īs with some humans, you may not want to test a bonobo’s patience. They respond just like human toddlers (and sometimes adults!) who are denied a treat or are frightened or upset by something. What is a chimpanzee or bonobo tantrum?Īnyone who has worked with chimpanzees or bonobos knows they can throw tantrums and scream VERY loudly, with hearing protection signs located in areas where zoo keepers work near these apes. ![]() They are both so much like us - only more hairy - but with bonobos easily recognised by their centre-parted hairstyles and cheek whiskers! Genome sequencing has shown more than 3% of our human genome is more closely related to either chimpanzees or bonobos than they are to each other. Meneer Zjeroen īoth species are intelligent, are long-lived with long childhoods, develop friendships and laugh when they are tickled. Chimpanzees are not immune to the odd pout or tanty.
