Enumeration of objects and substances in non-human primates: experiments with brown lemurs (Eulemur fulvus).
- PsychologyDevelopmental science
- 2009
Whether non-human primates' object tracking abilities are subject to the same constraints as those of human infants is explored and whether one primate species, the brown lemur (Eulemur fulvus), also fails to represent and enumerate objects when they behave non-rigidly or non-cohesively is examined.
Inherently Analog Quantity Representations in Olive Baboons (Papio anubis)
- Biology, PsychologyFront. Psychol.
- 2013
Evidence favoring analog numerical representation emerged from both conditions, and was present even in the first exposure to number pairs, suggesting that a single, coherent analog representation system underlies spontaneous quantitative abilities in primates.
Prosimian Primates Show Ratio Dependence in Spontaneous Quantity Discriminations
- PsychologyFront. Psychology
- 2012
Prosimians were not able to robustly discriminate quantities that differed by a 1:2 ratio for the same three conditions, nor did they show a preference for small quantities that differ by a 2:3 ratio, which implicate the ANS in the spontaneous numerical discriminations of non-human primates.

Processing Individually Distinctive Schematic-Faces Supports Proto-Arithmetical Counting in the Young Domestic Chicken
- PsychologyAnimals : an open access journal from MDPI

Simple Summary Baby chicks, like infants and other animals, are unable to distinguish 3 vs. 4 identical objects. Because infants and chicks discriminate among larger sets (e.g., 4 vs. 12; 6 vs. 9),…
When quantity trumps number: discrimination experiments in cotton-top tamarins (Saguinus oedipus) and common marmosets (Callithrix jacchus)
- BiologyAnimal Cognition
- 2007
These studies demonstrate that non-human primates possess mechanisms that enable quantification of total amount, in addition to the numerical representations demonstrated in previous studies, with both types of quantification subject to similar processing limits.
Are Monkeys Sensitive to the Regularity of Pay-off?
- Psychology
- 2011
Animals commonly face fluctuations in their environment and resources. To maximize their benefits, they need to integrate the risks attached to potential pay-offs. We do not know, however, to what…
The rewarding effects of number and surface area of food in rats
- Biology, PsychologyLearning & behavior
- 2018
It is suggested that density has an important role in food perception—that is, the rewarding effect of higher numerosity or larger surface area is removed when the food does not fill out the entire space.
From numerical concepts to concepts of number
- PsychologyBehavioral and Brain Sciences
- 2008
Two possible routes to mathematics are evaluated and it is suggested that children may arrive at natural numbers and arithmetic in a more top-down way, by constructing mathematical schemas.
1 < 2 and 2 < 3: Non-Linguistic Appreciations of Numerical Order
- PsychologyFront. Psychology
- 2013
It is suggested that patterns in the way that infants and non-human animals process numerical order can be accounted for by changes across development, the conditions under which representations are generated, or both.

Capuchin monkeys' ability to select the greater of two quantities of either discrete objects or a nonsolid substance is tested, suggesting that capuchins quantify objects and substances similarly and do so via analog magnitude representations.

Rhesus monkeys represent the numerosities 1 to 9 on an ordinal scale and detect their ordinal disparity, and use numerical representations computationally to represent visual stimuli.
The Representations Underlying Infants' Choice of More: Object Files Versus Analog Magnitudes

The pattern of success and failure of infants' spontaneous representations of more and less supports the hypothesis that they relied on object-file representations, comparing mental models via total volume or surface area rather than via one-to-one correspondence between object files.
Ordinal Judgments of Numerical Symbols by Macaques (Macaca Mulatta)

Two rhesus monkeys (Macaca mulatta) learned that the arabic numerals 0 through 9 represented corresponding quantities of food pellets by manipulating a joystick, and made ordinal judgments of numerical symbols in accordance with their absolute or relative values.
