The Relationship Between Transitive Inference And Social Complexity

Decent Essays

INTRODUCTION As claims the premise below, the ecological (e.g., temperature, humidity, altitude, and alimentation) and social (relationships with the environment and other organisms) factors could mould the perceptual and cognitive characteristic of a given species. It means that among nonhumans vertebrates they learn differently and have difference intelligence. Some authors, such as Clayton et al. (1998), supports this point of view. But this is not a universal thought within the scientific world. Mcphail and Bolhuis (2001), for example, do not see a relation between cognitive abilities and ecological factors. Moreover, Mcphail (1982, 1885), with his “null hypothesis,” claims that all vertebrates non-humans are of equal intelligence. …show more content…

It can be pointed out as a social factor the complexity of the social group where a given species lives. Recently, it has been found evidence that supports the link between social complexity and transitive inference, which indicates that animals that show superior transitive reasoning are those who are highly social (Brannon et al., 2008). Transitive inference could be defined as “a form of deductive reasoning that allows one to derive a relation between items that have not been explicitly compared before” (Lazareva, 2012). To analyse the relation between transitive inference and social complexity, Brannon et al. (2008) use two laboratory experiments, which include two species of lemurs: ringtailed and mongoose lemurs. Ringtailed lemurs are highly social while mongoose lemurs are less social. Within the two experiments, Brannon et al. (2008) found that both species were capable of transitive inference, but ringtailed lemurs were more capable to detect the underlying linear order of an ordinal series. It means that the both species do not differ directly in their ability to make transitive inferences, but in their ability to detect the underlying linear order. So, according to Brannon et al. (2008), it suggests that the social complexity is important in order to detect and reason about the rank order of conspecifics, which are important to survive when animal lives in a complex social group with linear dominance
