Journal ArticleDOI

Heart rate variability as a measure of autonomic regulation of cardiac activity for assessing stress and welfare in farm animals -- a review.

TL;DR: Data from earlier research demonstrate that HRV is a promising approach for evaluating stress and emotional states in animals, and has the potential to contribute much to the understanding and assessment of the underlying neurophysiological processes of stress responses and different welfare states in farm animals.
Journal Article

Emotions and cognition: a new approach to animal welfare

TL;DR: In this article, the authors apply appraisal theories to develop an experimental approach for studying the elementary criteria used by farm animals to evaluate their environment and the combinations of those criteria that trigger emotions.
Journal ArticleDOI

Changes in Heart Rate Variability during a tonic immobility test in quail.

TL;DR: The susceptibility to TI cannot be explained only by autonomic reflex changes, and is probably strongly related to the perception of the test by the quail, which reflects behavioural differences in the fear response.
Journal ArticleDOI

Emotional reactivity modulates autonomic responses to an acoustic challenge in quail.

TL;DR: Both the basal autonomic activity and the autonomic responses differed according to the emotional reactivity, and changes in autonomicActivity appear to be related to the genetic selection process.
Journal ArticleDOI

Emotions et cognition : stratégie pour répondre à la question de la sensibilité des animaux

TL;DR: L’approfondissement de l’etude des interactions entre emotions et cognition offre donc de nouvelles perspectives de recherche pour mieux comprendre les conditions of bien-etre des animaux en elevage.
