The study of laterality (i.e. asymmetries of brain and behaviour) is a potential non-invasive approach to gain insights into the common neural mechanisms underpinning both personality and emotions in animals. The hypotheses underlying this thesis state that the left (respectively the right) hemisphere regulates approach or positive (respectively avoidance or negative) emotions. The goal of this thesis was to study lateralized motor functions (Study 1) and their associations with personality indices (Study 2), and the effect of monocular viewing on emotional reactions (Study 3) in pigs.<eng>
