  Title Laterality of horses associated with emotionality in novel situations Type Journal Article
  Year 2006 Publication Laterality Abbreviated Journal Laterality  
  Volume 11 Issue 4 Pages 355-367  
  Keywords Affect/*physiology; Animals; Brain/*physiology; Female; Functional Laterality/*physiology; Horses; Male; *Social Behavior; *Social Environment  
  Abstract We have established that lateral biases are characteristic of visual behaviour in 65 horses. Two breeds, Trotters and French Saddlebreds aged 2 to 3, were tested on a novel object test. The main finding was a significant correlation between emotionality index and the eye preferred to view the novel stimulus: the higher the emotionality, the more likely that the horse looked with its left eye. The less emotive French Saddlebreds, however, tended to glance at the object using the right eye, a tendency that was not found in the Trotters, although the emotive index was the same for both breeds. The youngest French Saddlebreds did not show this trend. These results are discussed in relation to the different training practices for the breeds and broader findings on lateralisation in different species.

  Title Socially dependent auditory laterality in domestic horses (Equus caballus) Type Journal Article
  Year 2009 Publication Animal Cognition Abbreviated Journal Anim. Cogn.  
  Volume 12 Issue Pages 611-619  
  Keywords  
  Abstract Laterality is now known to be an ubiquitous phenomenon among the vertebrates. Particularly, laterality of auditory processing has been demonstrated in a variety of species, especially songbirds and primates. Such a hemispheric specialization has been shown to depend on factors such as sound structure, species specificity and types of stimuli. Much less is known on the possible influence of social familiarity although a few studies suggest such an influence. Here we tested the influence of the degree of familiarity on the laterality of the auditory response in the domestic horse. This species is known for its social system and shows visible reactions to sounds, with one or two ears moving towards a sound source. By comparing such responses to the playback of different conspecific whinnies (group member, neighbor and stranger), we could demonstrate a clear left hemisphere (LH) preference for familiar neighbor calls while no preference was found for group member and stranger calls. Yet, we found an opposite pattern of ear side preference for neighbor versus stranger calls. These results are, to our knowledge, the first to demonstrate auditory laterality in an ungulate species. They open further lines of thought on the influence of the social “value” of calls and the listener's arousal on auditory processing and laterality.

  Title Temperament and Personality in Horses: An Overwiev Type Conference Article
  Year 2008 Publication IESM 2008 Abbreviated Journal  
  Volume Issue Pages  
  Keywords  
  Abstract The existence of individual variations in behaviour has been demonstrated in all species investigated. Horses do show individual variations in a variety of behaviours from an early age on, as well as in behavioural traits underlying temperament/personality. Temperament is generally described as the “biological” (i.e.genetic) basis on which personality, as a result of environmental influences (i.e. experience), will be constructed. Indeed, genetic factors such as breed or patriline do have an influence on aspects like emotional reactions to fear-inducing situations or cognitive abilities while environmental factors, such as the conditions of life or the type of work performed, have also an influence on horse personality. We will review here the existing evidence of this interplay between genetic and environmental influences, showing that different traits can be differently influenced, and then look more thoroughly at the processes involved.

A particular accent will be given to the influence of the human-horse relation on personality traits of horses, both at adult stages through management, daily interactions and type of work, and at early stages through management and handling of foals.

The question of the stability of traits across situations and over time, that is of the possible predictibility of behavioural traits, is central, especially where the transfer from experimental situations (behavioural tests) to working situations and performance is concerned. The question of methodological approaches (behavioural tests, observations, questionnaires) can be crucial here and will be discussed.

In overall, this review should help understanding the determinants of horse temperament/personality traits and their implication in terms of choice of the appropriate horse for a given owner, better management and training for a better welfare and horse-human relationship. Genetic influences may lead to different susceptibilities to the same environmental conditions which mean that there are no such thing as “bad” or “good” horse temperaments but rather different horse types that may require different management or training schedules.
