Abstract:

A vocalisation may be described as a historical linguistic change where a sound which is formerly consonantal within a language becomes pronounced as a vowel. Although vocalisations have occurred sporadically in many languages they are particularly prevalent in the history of Germanic languages and have affected sounds from all places of articulation. This study will address two main questions. The first is why vocalisations happen so regularly in Germanic languages in comparison with other language families. The second is what exactly happens in the vocalisation process. For the first questio

Abstract:

Though human nonverbal vocalisations are widespread, scientific consideration of their mechanisms and communicative functions has been largely overlooked. This is despite their close alignment with the vocal communicative systems of primates and other mammals, whose primary function is to signal indexical information relevant to sexual and natural selection processes. In this thesis, I examine human nonverbal vocalisations from an evolutionary perspective, with the central hypothesis that they are functionally and structurally homologous to nonhuman mammal calls, communicating evolutionarily r

Abstract:

Infant vocalisations are uniquely salient sounds in the environment. They universally attract attention and compel the listener to respond with speed and care. They provide a wealth of information to parents about their infant’s needs and affective state. There is a scientific consensus that early parenting has a profound impact on child development. In particular, the sensitivity with which parents respond to their infant’s communicative cues has been shown to affect cognitive and socio-emotional outcomes. The mechanisms underlying such sensitivity are not well understood. In this thesis, adu

Chez les espèces sociales, les vocalisations transmettent des informations qui participent au maintien et à la survie du groupe. Alors que de nombreuses études se sont intéressées aux informations stables portées par les vocalisations telles que l’identité, peu d’études se sont interrogées sur le rôle des signaux vocaux dans la transmission des informations plus labiles, telles que l’état émotionnel de l’émetteur. Le stress est un bon candidat pour l’étude de l’expression des émotions chez les animaux, puisqu’il est directement mesurable via un dosage de la concentration plasmatique en glucoco

Abstract:

Vocal communication underpins behavioural interactions in many species. Receivers often show flexible responses to the same or acoustically similar vocalisations, but the causes and adaptive significance of this flexibility remain poorly understood in comparison to variation in signaller behaviour. In this thesis, I explore flexibility in responses to anti-predator vocalisations depending on caller identity and context, using dwarf mongooses (Helogale parvula) as a model system. I demonstrate that foragers rely more on surveillance calls from dominant sentinels compared to subordinates; domina

Abstract:

Vocal production: Guinea pigs (GP) are gregarious animals with a well-characterised repertoire of 11 vocalisations. These are context dependent, communicating information about danger, identity and emotional state. Vocalisations have previously been produced by electrical stimulation of three areas in the GP brain: anterior cingulate, hypothalamus and periaqueductal grey. These vocalisations were reported as natural-sounding, but with little or no spectral analysis to support this assertion. I elicited calls from urethane-anaesthetised GP by stimulating all the above areas, and from the amygda

North American red squirrels are a solitary, territorial species that confront various predators. Previous research proposed that squirrels produce predator-specific, referential ‘seet’ and ‘bark’ alarm calls to aerial and ground predators, respectively. To test this hypothesis, I examined alarm call production during natural encounters with predators, conspecific intruders and in a series of predator simulation experiments. Call production patterns were consistent across all types of disturbance and involved protracted bouts where both call types were inter-mixed. Hence, the call types were n

Abstract:

Recent studies have shown that there is a visual influence early in speech processing - visual speech enhances the ability to detect auditory speech in noise. However, identifying exactly how visual speech interacts with auditory processing at such an early stage has been challenging, because this so-called AV speech detection advantage is both highly related to a specific lower-order, signal-based, optic-acoustic relationship between the second formant amplitude and the area of the mouth (F2/Mouth-area), and mediated by higher-order, information-based factors.

Abstract:

The loud songs of gibbons (Hylobatidae) usually consist of a duet by the mated pair delivered each morning. These songs can transmit over a kilometre through dense forest habitat and therefore presumably play a role in long-distance communication. There is some evidence to suggest that gibbons use song in contexts other than their daily duets, such as predation, but these songs have not been well studied. Close- range communication is also relevant for gibbons, but these quieter calls have completely escaped any detailed observation. The responses of wild white-handed gibbons (Hylobates lar) t

Abstract:

Titi monkeys have long been known for their complex vocal behaviour with numerous high- and low-pitched calls, which can be uttered singly or combined in more complex structures. However, up to date very little is known concerning the function, meaning and context-specific use of these vocal utterances, and virtually nothing is known about their vocalisations in the predation context. This thesis presents a detailed description of the form and function of the anti-predator behaviour of one species of titi monkeys, the black-fronted titi monkey (Callicebus nigrifrons), with a specific focus on

Abstract:

Depuis quelques années, l’étude du code neuronal impliqué dans la perception des signaux de communication acoustique est devenue un domaine de recherche considérable. La littérature récente de ce domaine suggère que la discrimination entre ces signaux reposerait plutôt sur une organisation des décharges neuronales en motifs temporels que sur des variations globales de taux de décharge. Ma thèse a eu pour objectif de déterminer dans quelle mesure une régulation des inhibitions corticales peut (i) changer les motifs temporels déclenchés par des vocalisations conspécifiques et hétérospécifiques e

Abstract:

In the shallow coastal waters of New Zealand, sounds of biological origin dominate the lower frequency spectrum of the underwater soundscape. While the sounds of urchin and snapping shrimp have been well described, those of fish are poorly understood. Utilising sound recordings taken from a reef in the Cape Rodney to Okakari Point Marine Reserve, the present study described the vocalisations of two dominant fish vocalisations, the croak and the purr. These sounds dominated the soundscape at frequencies below 500 Hz and regularly formed choruses that lasted up to 3 hours after sunset during the

Abstract:

An automatic analysis of bird vocalisations for the identification of bird species, the study of their behaviour and their means of communication is important for a better understanding of the environment in which we are living and in the context of environmental protection. The high variability of vocalisations within different individuals makes species’ identification challenging for bird surveyors. Hence, the availability of a reliable automatic bird identification system through their vocalisations, would be of great interest to professionals and amateurs alike. A part of this thesis provi

Abstract:

Dogs and humans have through domestication and co-evolution established a close relationship and can communicate and understand each other. The objective of the present study was to deepen the understanding of the communication between dogs and humans, with focus on the vocalized communication. The study was based on video and audio recordings of dog-human communications from a total of 36 dogs in their home environment. The mean gap size in the communication ranged from 0.651.16 seconds and the overlap in communication had a percentage range of 14-50 %. These results are within the frame of o

Abstract:

Le conditionnement de peur est l’une des tâches les plus utilisées pour étudier la formation des mémoires émotionnelles. Dans cette thèse, nous nous sommes intéressées au conditionnement de peur à l’odeur dans lequel l’arrivée d’une odeur est suivie après un intervalle de temps fixe d’un stimulus aversif. L’animal apprend très rapidement que l’odeur prédit l’arrivée du stimulus aversif et développe une réponse de peur à l’odeur caractérisée par différents comportements tels que l’immobilité de peur, l’émission de vocalisations ultrasonores, ou des variations du rythme respiratoire.

Abstract:

Techniques of single- and multi-beam active acoustics and the passive recording of fish vocalisations were employed to evaluate the benefits and limitations of each technique as a method for assessing and monitoring fish aggregations. Five species, Samson fish (Seriola hippos), mulloway (Argyrosomus japonicus), West Australian dhufish (Glaucosoma hebraicum), Bight redfish (Centroberyx gerrardi) and pink snapper (Pagrus auratus) were investigated on the basis of their abundance, ecological importance and differing behaviour. The primary focus was on S. hippos, a large nonvocal schooling fish, a

Abstract The preverbal vocalisation up to the first word, feeding skills as well as motor development until the first steps of ELBW preterm infants without disability were compared in this descriptive study to those of healthy full-term infants. In addition, preverbal and feeding skills were studied in relation to gross motor movement patterns. The preverbal development of preterm infants proceeded according to the same temporal schedule as that of full-term infants, however, preterm infants failed to produce several vocalisation skills that full-term infants presented.
