Measuring communicative complexity across modalities: a new framework in the context of the “social complexity hypothesis” and its application in true lemurs
(2021-03-25)Animals exhibit an astonishing diversity of communicative systems, with substantial variation in both the nature and the number of signals they produce. Variation in communicative complexity has been conceptually and ... -
Mother-infant relationships in wild Guinea baboons (Papio papio)
(2023-02-16)During infancy, primates are heavily dependent on their mothers for nursing, transport, and thermoregulation, but also benefit from associating with their mothers for protection and social support. Furthermore, the mother ... -
Neuronal and Perceptual Effects of Selective Attention in the Primate Visual System
(2010-07-21)The work included in this thesis examines cognitive influences on the processing of visual information both on the neural and the behavioral level. A prominent mechanism for the ... -
Optimization of experimental procedures for the assessment of auditory cognition in non human primates
(2024-02-23)In a loose sense, the exceptional development of technology in the past three decades has allowed researchers to drastically improve the quality and quantity of behavioral data. However, the methodological advances achieved ... -
Phylogeny of Gibbons (Family Hylobatidae) with Focus on Crested Gibbon (Genus Nomascus)
(2010-05-10)Although the phylogeny and phylogeography of gibbons (Hylobatidae), a primate family endemic to Southeast Asia, has been studied in detail, phylogenetic relationships among taxa remain ... -
Regulation of inter-sexual relationships within the microcosm of Guinea baboon units
(2023-03-03)Male reproductive success is linked in most animals to their access to fertile females. Resulting competition among males presents a strong selective pressure on male reproductive strategies. In species with female choice ... -
Roots of Primate Cognition. The Primate Cognition Test Battery applied to three species of lemurs (Varecia variegata, Lemur catta and Microcebus murinus).
(2018-05-16)Compared to other mammals, primates have evolved relatively large brains and outstanding cognitive skills. Given that brain tissue is energetically very costly, one major evolutionary question concerns possible selection ... -
Social and Physical Cognition in Old World Monkeys - A Comparative Perspective
(2012-08-01)Primates have brains that are approximately twice as large as those of other similarly-sized mammals. Furthermore, also within the primate order brains have not only become increasingly large, but have also revealed ... -
Social information sampling and decision-making: An evolutionary and ontogenetic perspective
(2023-05-16)An advantage of being a group-living-, as opposed to a solitary-species, is having the opportunity to engage with conspecifics in mutually beneficial cooperative activities. Choice of cooperation partner often decides ... -
Social tolerance: novel insights from wild female crested macaques, Macaca nigra
(2013-09-24)Sociality is ultimately beneficial for individuals. Social relationships amongst individuals are viewed as long-term investments, influencing individual fitness. Analyses of the costs (competition) and benefits (cooperation) ... -
The Development of Recursive Meta-Representational Theory of Mind
(2023-06-02)Domain-general theories of Theory of Mind development assume that the ability to understand mental states (representations) as such is based on a fundamental understanding of representa-tions as representations ... -
The evolutionary roots of intuitive statistics
(2018-12-04)Intuitive statistical reasoning is the capacity to draw intuitive probabilistic inferences based on an understanding of the relations between populations, sampling processes and resulting samples. This capacity is fundamental ... -
The impact of vocal expressions on the understanding of affective states in others
(2015-03-17)Understanding emotions of social partners is of fundamental importance in day-to-day life. Humans share their affective states and intentions not only by language, but also by facial expressions, body posture or tone of ... -
The Social System of Guinea Baboons (Papio papio) With a Focus on Male-Male Relationships
(2013-07-26)Understanding the driving forces in human social evolution is still a major aim in anthropological and primatological research. Baboons (Papio spp.) have traditionally served as a model in this context. Originating in ... -
Theoretical and empirical analysis of the evolution of cooperation
(2014-09-25)Cooperative behaviour is widespread among humans and throughout the animal kingdom. Previous models suggest that the evolution of cooperation can be enhanced by network structure. However, recent experiments were not able ... -
Theory of Mind and Emotion Recognition
(2013-05-28)Perceiving and understanding social stimuli, including facial expressions, body language and vocalizations, is essential to human interactions. The ability to correctly identify internal states of others through such ... -
Verbesserung kognitiver Leistungen bei chronischer Schizophrenie durch rekombinantes humanes Erythropoietin (rhEPO)
(2008-07-15)Schizophrenia is increasingly recognized as a neurodevelopmental disease with an additional degenerative component, comprising cognitive decline and loss of cortical gray matter. ... -
Vocal communication in a tolerant multi-level society: insights from signallers and receivers in Guinea baboons
(2013-07-03)When studying the evolution of animal communication it is important to consider both, the signaller (i.e. signal structure and signal usage) and the receiver (i.e. signal response). While in primates the structure of sounds ... -
Vocal Communication within the Genus Chlorocebus: Insights into Mechanisms of Call Production and Call Perception
(2013-09-11)It is difficult to overestimate the influence of language in day to day life, and language is often proposed as the clearest feature to distinguish us, Homo sapiens, from all other animals. The origin of language has long ... -
Vocal repertoires of two matrilineal social whale species Long-finned Pilot whales (Globicephala melas) & Killer whales (Orcinus orca) in northern Norway
(2017-05-10)The aim of this study was to describe and investigate the vocal repertoire and possible factors influencing the size and composition of two matrilineal social whale species: long-finned pilot whales and killer whales in ...
