Assumptions on the neural basis of cognition usually focus on cortical mechanisms. Birds
have no cortex, but recent studies in parrots and corvids show that their cognitive skills are …

The last several decades of research on avian cognition have revealed surprising parallels
between the abilities of birds—most notably corvids—and great apes. Parrots, albeit far less …

Now more than ever animal studies have the potential to test hypotheses regarding how
cognition evolves. Comparative psychologists have developed new techniques to probe the …

Highlights•Social cognition in animals relies on a suite of increasingly complex skills.•These
skills are targets of selection.•They reflect the selective pressures acting on individuals in …

It is surprising that there are inconsistent findings of transitive inference (TI) in young infants
given that non‐linguistic species succeed on TI tests. To conclusively test for TI in infants, we …

A core feature of social intelligence is the understanding of third-party relations, which has
been experimentally demonstrated in primates. Whether other social animals also have this …

The requirements of living in social groups, and forming and maintaining social relationships
are hypothesized to be one of the major drivers behind the evolution of cognitive abilities …

ABSTRACT The Social Intelligence Hypothesis (SIH) is one of the leading explanations for
the evolution of cognition. Since its inception a vast body of literature investigating the …

During the last 50 years, comparative cognition and neurosciences have improved our
understanding of animal minds while evolutionary ecology has revealed how selection acts …

Rich behavioral and neurobiological evidence suggests cognitive and neural overlap in how
quantitatively comparable dimensions such as quantity, time, and space are processed in …
