Comparing Geometric Shape Representations in Humans and Baboons: A Language of Thought Perspective
In various cultures, across history and at many different spatial scales, humans produce a rich variety of geometric shapes. Recent work has put forward a concrete proposition for a Language of Thought (LoT) underlying the mental representation of geometric shapes in contemporary humans. Initial experiments, based on a comparison of baboon and human performance in an intruder task, suggested that this ability could be unique to humans. Here, to d…
No Evidence for Agent−Patient Role Attribution in Human Infants, Human Adults, and Guinea Baboons ( Papio papio)
Languages describe “who is doing what to whom” by distinguishing the event roles of agent (doer) and patient (undergoer), but it is debated whether they result from nonlinguistic representations that may already exist in preverbal infants and nonhuman animals. The phenomenon of causal perception, where the subsequent movements of two objects A and B evoke the impression of A launching B, is a simple depiction of an agent−patient relation. The sem…
The Lifetime of Sequential Memory Traces in the Absence of Language
Statistical learning allows us to implicitly create memory traces of recurring sequential patterns appearing in our environment. Here, we study the dynamics of how these sequential memory traces develop in a species of nonhuman primates (i.e., Guinea baboons, Papio papio ) that, unlike humans, cannot use language and verbal recoding strategies to strengthen these memory traces. We test a group of Guinea baboons in a Hebb visuo‐motor pointing task…
Humans ( Homo sapiens ) but not baboons ( Papio papio ) demonstrate crossmodal pitch‐luminance correspondence
Humans spontaneously and consistently map information coming from different sensory modalities. Surprisingly, the phylogenetic origin of such cross‐modal correspondences has been under‐investigated. A notable exception is the study of Ludwig et al. (Visuoauditory mappings between high luminance and high pitch are shared by chimpanzees [Pan troglodytes] and humans. Proceedings of the National Academy of Sciences , 108 (51), 20661–20665) which repo…
Categorization of vocal and nonvocal stimuli in Guinea baboons ( Papio papio )
Categorization of vocal sounds apart from other sounds is one of the key abilities in human voice processing, but whether this ability is present in other animals, particularly nonhuman primates, remains unclear. In the present study, 25 socially housed Guinea baboons ( Papio papio ) were tested on a vocal/nonvocal categorization task using Go/Nogo paradigm implemented on freely accessible automated learning devices. Three individuals from the gr…
The baboon: A model for the study of language evolution
Enhanced Cognitive Flexibility in the Seminomadic Himba
Through codified rule-use, humans can accurately solve many problems. Yet, mechanized strategies can also be costly. After adopting a solution strategy, humans often become blind to alternatives, even when those alternatives are more efficient. Termed cognitive set, this failure to switch from a familiar strategy to a better alternative has been considered universally human. Yet, our understanding of this phenomenon is derived almost exclusively …
Convergent transformation and selection in cultural evolution
Effects of freely accessible computerized test systems on the spontaneous behaviors and stress level of Guinea baboons ( Papio papio )
Fagot and Paleressompoulle [Fagot and Paleressompoulle (2009) Behav Res Methods 41: 396-404] described a new automated learning device for monkeys (ALDM) to test the cognitive functions of nonhuman primates within their social groups. However, the impact of the ALDM procedure on animal well-being needs to be investigated. The present study assessed the consequences of ALDM testing on the behavioral repertoire of Guinea baboons (Papio papio) and t…
Baboons ( Papio papio ) spontaneously process the first‐order but not second‐order configural properties of faces
A two‐alternative forced‐choice discrimination task was used to assess whether baboons ( N =7) spontaneously process qualitative (i.e., first‐order) or quantitative (i.e., second‐order) variations in the configural arrangement of facial features. Experiment 1 used as test stimuli second‐order pictorial faces of humans or baboons in which the mouth and the eyes were rotated upside down relative to the normal face. Baboons readily discriminated two…
Amodal completion by baboons (Papio papio): Contribution of background depth cues
L'éthologie cognitive
Les singes s'épouillent, les araignées tissent, les lionnes chassent, les oiseaux chantent et les castors bâtissent. Les activités des animaux ont toujours beaucoup intéressé les biologistes et les psychologues. Mais l'étude des interactions de l'animal avec son milieu ne peut pas s'arrêter là : il faut aussi prendre en compte la perception que cet animal se fait des situations rencontrées ainsi que les émotions qu'il éprouve à leur sujet. Force …
A multi-task assessment of hand lateralization in capuchin monkeys (Cebus apella)
Manual laterality in nonhuman primates: A distinction between handedness and manual specialization
This article examines individual and group manual lateralization in nonhuman primates as a function of task's demands. It is suggested to distinguish low- from high-level manual activities with respect to the novelty variable and to the spatiotemporal scale of the movements. This review shows that low-level tasks lead to (a) symmetrical distributions of hand biases for the group and (b) manual preferences that are not indicative of the specializa…
