Bolder Marmoset Monkeys Learn Faster Than Shy Ones
Cognitive capabilities in marmoset monkeys are influenced by both their personality as well as family group membership
By: University of Vienna
It has long been thought that only humans have personalities, but in recent decades personalities have been found in animals from spiders to apes. Similar personality traits are often shared between animals characterized as "friends" and sometimes even their whole social groups. Personalities have been linked to many life-history traits, but also to cognitive capabilities, like academic or work performance in humans. In animals, it has been suggested that more explorative and/or bolder individuals learn to solve various learning tasks faster. However, once they form these associations, they may be less flexible in reversing the learned links (as per the speed-accuracy trade-off model). Thus, in the new research article, Vedrana Šlipogor and colleagues from University of Vienna focused on exploring whether such a link is also present in common marmosets, cooperatively breeding monkey species that parallel humans in many socio-cognitive traits, and to which extent this is interlinked with their family group membership.
