Vocalization

Vocal correlates of emotional reactivity within and across contexts in domestic pigs (Sus scrofa)

Vocalizations have long been recognized to encode information about an individual's emotional state and, as such, have contributed to the study of emotions in animals. However, the potential of vocalizations to also encode information about an individual's emotional reactivity has...

Specific 50-kHz vocalizations are tightly linked to particular types of behavior in juvenile rats anticipating play

Rat ultrasonic vocalizations have been suggested to be either a byproduct of physical movement or, in the case of 50-kHz calls, a means to communicate positive affect. Yet there are up to 14 distinct types of 50-kHz calls, raising issues...

An unexpected acoustic indicator of positive emotions in horses

Indicators of positive emotions are still scarce and many proposed behavioural markers have proven ambiguous. Studies established a link between acoustic signals and emitter's internal state, but few related to positive emotions and still fewer considered non-vocal sounds. One of...

Communication during suckling in the domestic pig

Fan noise disrupted communication between sows and piglets during nursing, resulting in slower piglet growth. Certain indications were found that suggested that the noise-exposed piglets gained less milk than the ones in the silent environment.

Comment on ‘Are alarming events good for captive monkeys?’

The paper by Chamove and Moodie (Applied Animal Behaviour Science 27, 167-176, 1990) 'Are alarming events good for captive monkeys?' concludes that the capture and exposure to predators improves the behavioral well-being of captive cotton-top tamarins (Saguinus oedipus oedipus). We...

Baboon vocalizations as measures of psychological well-being

Increased grunting was associated with environmental enrichment [radio, food treats]. Thus vocalizations may provide a useful tool for evaluating enrichment programs designed to promote baboon, and perhaps other nonhuman primate, psychological well-being. ... With minimal training, caregivers can learn to...

The potential for utilizing acoustic communication as a form of behavioral enrichment

It is the purpose of this poster to show that acoustic recordings of animal vocalizations can become an important tool to be utilized under many different circumstances e.g., for audio enrichment.

Communication patterns within a group of shelter dogs and implications for their welfare

Keeping shelter dogs in groups provides them with a more socially and physically enriched environment, but eventually it may cause them stress. Understanding dogs' communication could help shelter staff recognize and prevent undesirable communicative patterns and encourage desirable ones. Therefore,...

Are 50-kHz calls used as play signals in the playful interaction of rats? I

During playful interactions, rats emit increased levels of 50-kHz vocalizations. It is possible that these vocalizations are used as play signals that promote and maintain playful contact. The study investigated this possibility. It was predicted that if these vocalizations are...
