Comparative psychology assesses cognitive abilities and capacities of non-human animals
and humans. Based on performance differences and similarities in various species in …

The presence of general intelligence poses a major evolutionary puzzle, which has led to
increased interest in its presence in nonhuman animals. The aim of this review is to critically …

To understand how our brain evolved and what it is for, we are in urgent need of knowledge
about the cognitive skills of a large variety of animal species and individuals, and their …

Primates have relatively larger brains than other mammals even though brain tissue is
energetically costly. Comparative studies of variation in cognitive skills allow testing of …

Comparative psychologists study cognition by characterizing the behavior of individual
species and explicitly comparing behavior across species. We use the extensive …

Games derived from experimental economics can be used to directly compare decision-
making behavior across primate species, including humans. For example, the use of …

Brain size variability in primates has been attributed to various domain-specific socio-
ecological factors. A recently published large-scale study of short-term memory abilities in …

Play in humans and other animals is widespread and intuitive to recognise. Creative,
unstructured play is difficult to quantify, but games direct play towards a specific goal and …

In the past decade, there has been a surge of interest in using games derived from
experimental economics to test decision-making behaviour across species. In most cases …

Recent evidence within the field of comparative psychology has demonstrated that small
differences in procedure may lead to significant differences in outcome. Therefore, failing to …
