Humans have many cognitive skills not possessed by their nearest primate relatives. The cultural intelligence hypothesis argues that this is mainly due to a species-specific set of social-cognitive skills, emerging early in ontogeny, for participating and exchanging knowledge in cultural groups. We tested this hypothesis by giving a comprehensive battery of cognitive tests to large numbers of two of humans' closest primate relatives, chimpanzees and orangutans, as well as to 2.5-year-old human… 
Primate Cognition
TLDR
Of special importance, the human primate seems to possess a species-unique set of adaptations for "cultural intelligence," which are broad reaching in their effects on human cognition.
The Structure of Individual Differences in the Cognitive Abilities of Children and Chimpanzees
TLDR
The proposal that humans share many cognitive skills with nonhuman apes, especially for dealing with the physical world, but in addition have evolved some specialized skills of social cognition is supported.
The Primate Origins of Human Social Cognition
TLDR
It is argued that this evolutionary perspective can help adjudicate between different proposals on the link between human-specific forms of social cognition and language, and then examine the evidence for apparently human-unique aspects of theory of mind that may be linked to language.
Old World Monkeys Compare to Apes in the Primate Cognition Test Battery
TLDR
The results question the clear-cut relationship between cognitive performance and brain size and support the view of an accelerated evolution of social intelligence in humans.
An Evolutionary Perspective on Primate Social Cognition
TLDR
This chapter introduces present avenues taken in research on primate social cognition, and it walks the reader through the chapters of this volume.
Old and New Approaches to Animal Cognition: There Is Not “One Cognition”
TLDR
It is argued that the term “cognition” has often been used by applying an anthropocentric viewpoint rather than a biocentric one and that to better understand animal minds, comparative researchers should focus much more on questions and experiments that are ecologically valid.
The evolution of primate general and cultural intelligence
TLDR
The findings question the independence of cognitive traits and do not support ‘massive modularity’ in primate cognition, nor an exclusively social model of primate intelligence, as well as an across-species general intelligence that includes elements of cultural intelligence.
Socio-Cognitive Specializations in Nonhuman Primates: Evidence from Gestural Communication
This chapter reviews primate cognitive abilities in physical, social, and communicative realms and asks (1) whether primates exhibit abilities that diff er from those of other animals, and (2) what

The Social Brain: Mind, Language, and Society in Evolutionary Perspective
TLDR
The extent to which the cognitive demands of bonding large intensely social groups involve aspects of social cognition, such as theory of mind, is explored and is related to the evolution of social group size, language, and culture within the hominid lineage.
Cognitive cladistics and cultural override in Hominid spatial cognition
TLDR
It is reasonable to conclude, it is argued, that language and culture mask the native tendencies in the authors' species, and the correct perspective on human cognition is neither nativist uniformitarian nor “blank slate” but recognizes the powerful impact thatlanguage and culture can have on their shared primate cognitive biases.

The Adapted mind : evolutionary psychology and the generation of culture
Although researchers have long been aware that the species-typical architecture of the human mind is the product of our evolutionary history, it has only been in the last three decades that advances
The Domestication of Social Cognition in Dogs
TLDR
It is found that wolves who were raised by humans do not show these same skills, whereas domestic dog puppies only a few weeks old, even those that have had little human contact, do show these skills.
Coevolution of neocortical size, group size and language in humans
TLDR
It is suggested that the evolution of large groups in the human lineage depended on developing a more efficient method for time-sharing the processes of social bonding and that language uniquely fulfills this requirement.
Understanding and sharing intentions: The origins of cultural cognition
TLDR
It is argued and present evidence that great apes understand the basics of intentional action, but they still do not participate in activities involving joint intentions and attention (shared intentionality), and children's skills of shared intentionality develop gradually during the first 14 months of life.
Our chimpanzee mind
TLDR
If comparative genomics is to enlighten the authors' understanding of human origins, it must be accompanied by an equally rich description of animal psychology, both in terms of its underlying neural signatures and the evolutionary processes that led to convergence and divergence with other species.
Early brain growth in Homo erectus and implications for cognitive ability
TLDR
An analysis of the 1.8-million-year-old Mojokerto child (Perning 1, Java), the only well preserved skull of a Homo erectus infant, by computed tomography indicates that this individual was about 1 yr (0–1.5”yr) old at death and had an endocranial capacity at 72–84% of an average adult H. erectus.
