Abstract

Mnogo se godina socijalno učenje, zajedno s tradicijom i kulturom, vezalo isključivo uz čovjeka. S druge strane, u zadnjih nekoliko godina mnoga su istraživanja pokazala socijalno prenošenje informacija i zadržavanje istih tijekom vremena i/ili unutar generacija u mnogim životinjskim vrstama. Nedavna istraživanja na primatima pokazala su uspješnu upotrebu video prikaza prilikom istraživanja prenošenja tehnika rješavanja problemskih zadataka u laboratoriju i u prirodi. U ovom sam radu koristila video prikaze kako bih odredila da li obični marmozeti (Callithrix jacchus) preferiraju učenje od virtualnog ne-socijalnog prikaza ili virtualnog demonstratora iste vrste. Nadalje, zanimalo me da li će majmuni slijediti demonstratorov izbor, tj. otvarati kutijicu iste boje kao što je prikazano na videu. Rezultati su pokazali da nema preferencije ni za socijalnu niti ne-socijalnu inormaciju, te kako nema preferencije ni za demonstriranu niti ne-demonstriranu kutijicu. S druge strane, pozornost majmuna na video prikaze, te izbor demonstrirane ili ne-demonstrirane kutijice za manipulaciju, pod utjecajem je njihove obiteljske skupine. Također, pokazane su i individualne razlike u pozornosti na video prikaz unutar faze prikazivanja i faze testiranja.

Abstract (english)

For many years, social learning as well as behavioral traditions and cultural phenomena, were thought to be distinctive to humans. In recent years, however, a lot of studies have shown evidence for the social transmission of information and its maintenance over time and/or generations in a variety of non-human animals. Recent studies on primates have shown successful use of video demonstration to investigate the transmission of techniques in problem-solving tasks in the laboratory and in the field. In this experiment, I used video demonstrations to determine if common marmosets (Callithrix jacchus) have a preference for learning from a virtual non-social demonstration or a virtual conspecific demonstrator. Further, I was interested to see whether the subjects follow a demonstrated choice i.e., opening of the same-colored container as shown in the videos. Results showed no preference for social or non-social demonstration, nor a preference for demonstrated or non-demonstrated box. However, both the monkeys’ attention for a video demonstration and choice to manipulate demonstrated or non-demonstrated containers have been influenced by their group. Furthermore, I found large inter-individual differences in attention to video demonstrations in both the demonstration and test phases.
