Pigeons, portals, and Pacman: Insightful problem solving and navigation using a touchscreen video game

Journal of the Experimental Analysis of Behavior, Volume 125, Issue 2, March 2026.
Abstract Video games have been used in several studies to investigate problem solving. We present empirical findings from a redesigned touchscreen navigation “grid‐world” procedure resembling the classic video game PacMan (hereafter, “pacman”) played by pigeons. Our objective was to develop a procedure to study insight, similar to that of Epstein et al.

Gorillas’ (Gorilla g. gorilla) knowledge of conspecifics’ affordances: intraspecific social tool use for food acquisition [PDF]

, 2020
The use of tools, long thought to be uniquely human, has now been observed in other animal taxa including several species of birds, non-primate mammals as well as some non-human primate species.

A Naturalistic Theory of (In)justice: How Neurophysiology and Metabolic Energy Ground the Perception of Injustice

Journal for the Theory of Social Behaviour, Volume 56, Issue 1, March 2026.
ABSTRACT Across different domains, justice is considered either from a perspective concerning mind‐independent features of a situation or from a perspective related to mind‐dependent motives, traits or emotions. Although these approaches have generated valuable insights, they remain largely disconnected from each other.

A phylogenomic perspective on the robust capuchin monkey (Sapajus) radiation : first evidence for extensive population admixture across South America [PDF]

, 2018
Phylogenetic relationships amongst the robust capuchin monkeys (genus Sapajus) are poorly understood. Morphology-based taxonomies have recognized anywhere from one to twelve different species.

Forest structure and connectivity drive the functional recovery of seed rain

Journal of Ecology, Volume 114, Issue 2, February 2026.
Local forest structure and landscape‐scale connectivity shape distinct but complementary pathways of the functional recovery of seed rain in tropical forests. Structural complexity promotes functionally diverse plant–frugivore interactions locally, while connectivity facilitates the arrival of late‐successional seeds from external sources.

Mechanical isolation of capuchin monkey (Cebus apella) preantral ovarian follicles

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2003
The aim of this study was to adapt a mechanical procedure for the isolation of intact preantral follicles from Cebus apella ovaries. The interval effect of serial sections of the tissue chopper was tested on a number of preantral follicles isolated from ...

Woolly Monkey–HBV Infection in Squirrel Monkeys as a Surrogate Nonhuman Primate Model of HBV Infection

Hepatology Communications, 2020
Development of curative therapies for chronic hepatitis B virus (HBV) infection will likely require new animal models. Here, we evaluate HBV infection in squirrel monkeys based on the high‐sequence homology of the HBV receptor, Na+/taurocholate co ...

Does opportunistic testing bias cognitive performance in primates? Learning from drop-outs [PDF]

, 2019
Dropouts are a common issue in cognitive tests with non-human primates. One main reason for dropouts is that researchers often face a trade-off between obtaining a sufficiently large sample size and logistic restrictions, such as limited access to ...

Artifact and Artifact Categorization: Comparing Humans and Capuchin Monkeys [PDF]

, 2013
International audienceWe aim to show that far-related primates like humans and the capuchin monkeys show interesting correspondences in terms of artifact characterization and categorization.

Do Social Conditions Affect Capuchin Monkeys’ (Cebus apella) Choices in a Quantity Judgment Task?

Frontiers in Psychology, 2012
Beran et al. (2012) reported that capuchin monkeys closely matched the performance of humans in a quantity judgment test in which information was incomplete but a judgment still had to be made.
