The ability to represent, discriminate, and perform arithmetic operations on discrete
quantities (numerosities) has been documented in a variety of species of different taxonomic …

'Accounting for the sensory abilities of animals is critical in experimental design.'No
researcher would disagree with this statement, yet it is often the case that we inadvertently …

The “mental number line”(MNL) is a form of spatial numeric representation that associates
small and large numbers with the left and right spaces, respectively. This spatio-numeric …

Human early visual cortex response amplitudes monotonically increase with numerosity
(object number), regardless of object size and spacing. However, numerosity is typically …

Debates have arisen as to whether non-human animals actually can learn abstract non-
symbolic numerousness or whether they always rely on some continuous physical aspect of …

Sensitivity to numbers is a crucial cognitive ability. The lack of experimental models
amenable to systematic genetic and neural manipulation has precluded discovering neural …

Interest in the advanced cognitive abilities of insects has grown rapidly over the past
decades. However, most studies have taken place on a handful of model organisms: fruit …

The studies of number sense in different species are severely hampered by the inevitable
entanglement of non-numerical attributes inherent in nonsymbolic stimuli representing …

A frequent question as technology improves and becomes increasingly complex, is how we
enable technological solutions and models inspired by biological systems. Creating …

Quantitative abilities are widely recognized to play important roles in several ecological
contexts, such as foraging, mate choice, and social interaction. Indeed, such abilities are …
