Intentional communication in primates

Zuberbühler, Klaus

In: Revue Tranel, 2018, vol. 68, p. 69-75

Human communication, including language, is the product of underlying intentions that are purposely expressed, epistemically monitored and flexibly interpreted. A main question in science has been about the evolutionary origins of this cognitive capacity. One way to address the problem is by studying the natural communication of animals, particularly nonhuman primates. As everything in biology,...

Kin-based cultural transmission of tool use in wild chimpanzees

Lamon, Noemie ; Neumann, Christof ; Gruber, Thibaud ; Zuberbühler, Klaus

In: Science Advances, 2017, vol. 3, no. 4, p. e160275

Current research on animal culture has focused strongly on cataloging the diversity of socially transmitted behaviors and on the social learning mechanisms that sustain their spread. Comparably less is known about the persistence of cultural behavior following innovation in groups of wild animals. We present observational data and a field experiment designed to address this question in a wild...

Female chimpanzees use copulation calls flexibly to prevent social competition

Townsend, Simon W ; Deschner, Tobias ; Zuberbühler, Klaus

In: PLoS ONE, 2008, vol. 3, no. 6, p. e2431

The adaptive function of copulation calls in female primates has been debated for years. One influential idea is that copulation calls are a sexually selected trait, which enables females to advertise their receptive state to males. Male-male competition ensues and females benefit by getting better mating partners and higher quality offspring. We analysed the copulation calling behaviour of...

The alarm call system of female Campbell's monkeys

Ouattara, Karim ; Zuberbühler, Klaus ; N'Goran, Koffi J.-N ; Gombert, Jean-Emile

In: Animal Behaviour, 2009, vol. 78, no. 1, p. 35-44

Field studies on male forest guenon alarm-calling behaviour have revealed a number of intricacies about how these primates use vocalizations to protect themselves from predation. In these species, the vocal behaviour of adult females is often different from that of the males, but little systematic work has been done. Here, we describe the alarm call system of female Campbell's monkeys,...

Campbell's Monkeys Use Affixation to Alter Call Meaning

Ouattara, Karim ; Lemasson, Alban ; Zuberbühler, Klaus

In: PLoS ONE, 2009, vol. 4, no. 11, p. e7808

Human language has evolved on a biological substrate with phylogenetic roots deep in the primate lineage. Here, we describe a functional analogy to a common morphological process in human speech, affixation, in the alarm calls of free-ranging adult Campbell's monkeys (Cercopithecus campbelli campbelli). We found that male alarm calls are composed of an acoustically variable stem, which...

The alarm call system of two species of black-and-white colobus monkeys (Colobus polykomos and Colobus guereza)

Schel, Anne Marijke ; Tranquilli, Sandra ; Zuberbühler, Klaus

In: Journal of Comparative Psychology, 2009, vol. 123, no. 2, p. 136-150

Vervet monkey alarm calling has long been the paradigmatic example of how primates use vocalizations in response to predators. In vervets, there is a close and direct relationship between the production of distinct alarm vocalizations and the presence of distinct predator types. Recent fieldwork has however revealed the use of several additional alarm calling systems in primates. Here, the...

Wild chimpanzees (Pan troglodytes schweinfurthii) distinguish between different scream types: evidence from a playback study

Slocombe, Katie Elizabeth ; Townsend, Simon W ; Zuberbühler, Klaus

In: Animal Cognition, 2009, vol. 12, no. 3, p. 441-449

When experiencing aggression from group members, chimpanzees commonly produce screams. These agonistic screams are graded signals and vary acoustically as a function of the severity of aggression the caller is facing. We conducted a series of field playback experiments with a community of wild chimpanzees in the Budongo Forest, Uganda, to determine whether individuals could meaningfully...
