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… Expand
Laterality and emotions: Visual laterality in the domestic horse (Equus caballus) differs with objects' emotional value
TLDR
This study is the first to demonstrate clearly that the emotional valence of a stimulus induces a specific visual lateralization pattern and suggest the importance of both hemispheres in the processing positive emotions. Expand
Asymmetry of behavioral responses to a human approach in young naive vs. trained horses
TLDR
The results show that the one year old untrained horses display asymmetrical responses to an approaching human, with more negative reactions when approached from the left side, while approaches towards the right shoulder elicited more positive behaviors. Expand
Visual laterality in the domestic horse (Equus caballus) interacting with humans
TLDR
It is suggested that most horses prefer to use their left eye for assessment and evaluation, and that there is an emotional aspect to the choice which may be positive or negative, depending on the circumstances. Expand
Sensory laterality in affiliative interactions in domestic horses and ponies (Equus caballus)
TLDR
The results suggest that right hemisphere specialization in horses is not limited to the processing of stressful or agonistic situations, but rather appears to be the norm for processing in all social interactions, as has been demonstrated in other species including chicks and a range of vertebrates.

Association Between Lateral Bias and Personality Traits in the Domestic Dog (Canis familiaris)
TLDR
Evidence is found of a link between canine personality and behavioral laterality, and this was especially true for those traits relating to stronger emotional reactivity, such as aggressiveness, fearfulness, and sociability. Expand
Lateralized suckling in domestic horses (Equus caballus)
TLDR
A general pattern of sucking with the left eye open for better danger detection and recognition is unlikely in foals up to 7 months old, and individual side preferences amongst foals are suggested to be based on motor lateralization. Expand
Lateralization of agonistic and vigilance responses in Przewalski horses (Equus przewalskii)
Abstract Eye and limb preferences were scored in the closest undomesticated relative of Equus caballus using the same methods as used previously to study laterality in feral horses. Observations wereExpand
Lateralized behaviour as indicator of affective state in dairy cows
TLDR
There was a trend for cows appearing hesitant in approaching the objects by stopping at a distance to them, to then explore the left object rather than the right, and trends suggesting that lateralized behaviour in response to bilaterally located unfamiliar objects may reflect an immediate affective response are discussed. Expand
Horses associate individual human voices with the valence of past interactions: a behavioural and electrophysiological study
TLDR
It is demonstrated that horses’ representation of human voices is modulated by the valence of prior horse-human interactions, as well as by the animals’ management conditions. Expand
Horses’ (Equus Caballus) Laterality, Stress Hormones, and Task Related Behavior in Innovative Problem-Solving
TLDR
It is concluded that horses’ keeping conditions and welfare may be improved by environmental enrichment which promotes the development of innovative behavior. Expand

Experimental tests to assess emotionality in horses
TLDR
Different tests were used to assess different aspects of the emotionality of 1-3 year-old horses: arena test; a `novel object' test; and a handling test, and indices were developed that enabled to rank the animals, by taking into account all behaviour patterns shown. Expand
Motor and sensory laterality in thoroughbred horses
Abstract We investigated lateralisation in horses because it is likely to be important in training and athletic performance. Thoroughbred horses (n = 106) were observed every 60 s for 2 h, when theyExpand
Stability over situations in temperamental traits of horses as revealed by experimental and scoring approaches
TLDR
Individual behavioural reactions of adult horses in a variety of experimental tests were compared with ratings by riding teachers, strengthening the idea that there are underlying behavioural dispositions that are stable across situations and that the experimental tests may be good predictors of the temperament in untrained animals.

factors Associated with Exploration in Marmosets: Age, Gender and Hand Preference
Age, hand preference and gender are shown to be associated with exploration behaviour performed by Callithrix jaccfius, depending on the context in which the marmosets are tested. When each marmosetExpand
Learning and memorisation of two different tasks in horses: the effects of age, sex and sire
Abstract Learning and memory abilities of 1–3 year old horses were assessed using instrumental and spatial tasks. No important differences were observed in the success of learning of the instrumentalExpand
Interocular transfer of learning in horses (Equus caballus)
TLDR
Horses demonstrated high levels of interocular transfer on the four problems and on the reversal discriminations, providing evidence that horses are capable of interhemispheric transfer of visual information. Expand

Early experiential effects on laterality: research on chicks has relevance to other species.
TLDR
The influence of early experience on the development of lateralisation of hemispheric function was further investigated, using the chick as a model, and the interactive effects of sex hormone levels on the differentiation ofateralisation are discussed. Expand
Lateralisation of function in the chicken fore-brain
There is lateralisation of function in the chicken fore-brain. This was revealed by examining the behavioural modifications produced by administration of cycloheximide into the left or rightExpand
Interplay between environmental and genetic factors in temperament/personality traits in horses (Equus caballus).
TLDR
Additive effects were evident, showing how environmental factors may modulate behavioral traits, and how the environment may intervene in determining individual behavioral characteristics, in Equus caballus. Expand
