Topic:Cognitive Science
Cognitive science in horses explores the mental processes and behaviors associated with perception, learning, memory, and decision-making in equine species. This field examines how horses process information, solve problems, and interact with their environment and other beings. Research in equine cognition involves studying various aspects such as sensory perception, social learning, and communication. The findings contribute to understanding the cognitive abilities of horses and inform training, management, and welfare practices. This page compiles peer-reviewed research studies and scholarly articles that investigate the cognitive processes and capabilities of horses, offering insights into their mental functioning and behavior.
Knowledge of lateralized brain function can contribute to animal welfare. The specialized functions of each hemisphere of the vertebrate brain are summarized together with the current evidence of lateralized behavior in farm and companion animals, as shown by the eye or ear used to attend and respond to stimuli. Forelimb preference is another manifestation of hemispheric lateralization, as shown by differences in behavior between left- and right-handed primates, left- and right-pawed dogs and cats, and left- and right-limb-preferring horses. Left-limb preference reflects right hemisphere use and is associated with negative cognitive bias. Positive cognitive bias is ...
The Effect of Equine-Assisted Activities in Children Aged 7-8 Years Inhibitory Control: An fNIRS Study. Inhibitory control (IC), an important component of executive function, plays an important role in the overall development of children and has not been better studied in the field of equine-assisted activity (EAA). Therefore, this study investigated the effects of EAA on IC and the underlying brain neural mechanisms in children aged 7-8 years. Conclusions: Collectively, EAA demonstrated a positive impact on IC and could effectively activate R-DLPFC in children aged 7-8 years. Furthermore, it enhanced the activation of the brain regions related to IC and increased cognitive ability in children a...
The effects of equine-assisted activities on execution function in children aged 7-8 years: A randomized controlled trial. This study examines the effects of equine-assisted activity (EAA) training on executive functioning (EF) (inhibitory control, working memory, and cognitive flexibility) in children aged 7-8 years. Methods: Twenty-Four healthy children aged 7-8 years with a 1:1 ratio of boys to girls were randomly divided into EAA group (EAAG) or control group (CG). The subjects in EAAG were trained for 12 weeks, and CG participated in normal daily activities. All subjects conducted the Flanker, 1-Back, and More-odd shifting tasks at rest and recorded the average reaction times (RTs) and accuracy data of each t...
Equine assisted services impact on social skills in autism spectrum disorder: A meta-analysis. Many studies focus on the impact of equine assisted services (EAS) on social skills in autism spectrum disorder (ASD) but existing data are not consensual and the only available meta-analysis included only three studies and did not consider the social responsiveness scale (SRS). This meta-analysis aims to measure the impact of EAS on social skills in ASD. Using Pubmed, Embase, Web of Science and the Cochrane Library, the means and standard deviations of every available SRS post-intervention scores in each participant group were collected from the five selected randomised controlled trials with...
Horses cross-modally recognize women and men. Several studies have shown that horses have the ability to cross-modally recognize humans by associating their voice with their physical appearance. However, it remains unclear whether horses are able to differentiate humans according to different criteria, such as the fact that they are women or men. Horses might recognize some human characteristics, such as sex, and use these characteristics to classify them into different categories. The aim of this study was to explore whether domesticated horses are able to cross-modally recognize women and men according to visual and auditory cues, using...
Do you see what I see? Testing horses’ ability to recognise real-life objects from 2D computer projections. The use of 2-dimensional representations (e.g. photographs or digital images) of real-life physical objects has been an important tool in studies of animal cognition. Horses are reported to recognise objects and individuals (conspecifics and humans) from printed photographs, but it is unclear whether image recognition is also true for digital images, e.g. computer projections. We expected that horses trained to discriminate between two real-life objects would show the same learnt response to digital images of these objects indicating that the images were perceived as objects, or representation...
How to Understand Them? A Review of Emotional Indicators in Horses. Stabled horses often experience negative emotions due to the inappropriate living conditions imposed by humans. However, identifying what emotions horses experience and what can trigger positive and negative emotions in stabled horses can be challenging. In this article we present a brief history of the study of emotions and models that explain emotions from a scientific point of view and the physiological bases and functions of emotions. We then review and discuss physiological and behavioral indicators and cognitive bias tests developed to assess emotions in horses. Hormone concentrations, b...
Effects of Equine-Assisted Activities and Therapies for Individuals with Autism Spectrum Disorder: Systematic Review and Meta-Analysis. Autism spectrum disorder (ASD) has become a critical public health issue that affects more than 78 million people. In many recent studies, the authors have demonstrated that equine-assisted activities and therapies (EAATs) can substantially improve the social and behavioral skills of children with ASD. However, the qualities of the studies differ, and some authors reached opposite conclusions. In this review, we systematically and objectively examined the effectiveness of EAATs for people with ASD, combining both qualitative and quantitative methods. We searched five databases (PubMed, Scopus,...
Garrano Horses Perceive Letters of the Alphabet on a Touchscreen System: A Pilot Study. This study aimed to use a computer-controlled touchscreen system to examine visual discrimination in Garrano horses (), an endangered breed of pony belonging to the Iberian horse family. This pilot study focused on the perceptual similarity among letters of the alphabet. We tested five horses in a one-male unit (OMU) living permanently in a semi-free enclosure near their natural habitat in Serra d'Arga, northern Portugal. Horses were trained to nose-touch black circles that appeared on the screen. Then, they were tested for discrimination of five letters of the Latin alphabet in Arial font, na...
Habit Formation and the Effect of Repeated Stress Exposures on Cognitive Flexibility Learning in Horses. Horse training exposes horses to an array of cognitive and ethological challenges. Horses are routinely required to perform behaviours that are not aligned to aspects of their ethology, which may delay learning. While horses readily form habits during training, not all of these responses are considered desirable, resulting in the horse being subject to retraining. This is a form of cognitive flexibility and is critical to the extinction of habits and the learning of new responses. It is underpinned by complex neural processes which can be impaired by chronic or repeated stress. Domestic horses...
Horses’ attentional characteristics differ according to the type of work. Attention is a central process of cognition and influences the execution of daily tasks. In humans, different types of work require different attentional skills and sport performance is associated with the ability to attention shift. Attention towards humans varies in dogs used for different types of work. Whether this variation is due to the recruitment of individuals suitable for specific types of work, or to the characteristics of the work, remains unclear. In the present study, we hypothesized that domestic horses (Equus caballus) trained for different types of work would also demonstrate ...
Getting rid of blinkers: the case of mirror self-recognition in horses (Equus caballus). The commentary by Gallup and Anderson (Anim Cogn https://doi.org/10.1007/s10071-021-01538-9 , 2021) on the original article by Baragli, Scopa, Maglieri, and Palagi (Anim Cogn https://doi.org/10.1007/s10071-021-01502-7 , 2021) raised some concerns about the methodological approach used by the authors to demonstrate Mirror Self-Recognition (MSR) in horses. The commentary does not take into account horse physiology and psychology, leading Gallup and Anderson to inappropriately discredit the findings obtained by Baragli et al. Anim Cogn 2021. In this reply, we underlined the importance of a blinke...
Cognition and the human-animal relationship: a review of the sociocognitive skills of domestic mammals toward humans. In the past 20 years, research focusing on interspecific sociocognitive abilities of animals toward humans has been growing, allowing a better understanding of the interactions between humans and animals. This review focuses on five sociocognitive abilities of domestic mammals in relation to humans as follows: discriminating and recognizing individual humans; perceiving human emotions; interpreting our attentional states and goals; using referential communication (perceiving human signals or sending signals to humans); and engaging in social learning with humans (e.g., local enhancement, demo...
Cross-Modality Interaction Network for Equine Activity Recognition Using Imbalanced Multi-Modal Data. With the recent advances in deep learning, wearable sensors have increasingly been used in automated animal activity recognition. However, there are two major challenges in improving recognition performance-multi-modal feature fusion and imbalanced data modeling. In this study, to improve classification performance for equine activities while tackling these two challenges, we developed a cross-modality interaction network (CMI-Net) involving a dual convolution neural network architecture and a cross-modality interaction module (CMIM). The CMIM adaptively recalibrated the temporal- and axis-wis...
Putting the cart before the horse: claims for mirror self-recognition in horses are unfounded. The recent article by Baragli, Scopa, Maglieri, and Palagi (Anim Cogn https://doi.org/10.1007/s10071-021-01502-7 , 2021) that claims to demonstrate mirror self-recognition (MSR) in horses is not based on compelling evidence. We identify problems with their experimental procedures, data, and assertion about "demonstrating MSR at group level." Examples of these problems include incomplete experimental design, absence of important control conditions, inappropriate terminology, suboptimal mark application procedures and coding of videos, ambiguity of videos presented as supporting evidence, and in...
Using the Judgment Bias Task to Identify Behavioral Indicators of Affective State: Do Eye Wrinkles in Horses Reflect Mood? Identifying and validating behavioral indicators of mood are important for the assessment of animal welfare. Here, we investigated whether horses' eye wrinkle expression in a presumably neutral situation is a measure of mood as assessed in a cognitive judgment bias task (JBT). To this end, we scored pictures of the left and right eyes of 16 stallions for different aspects of eye wrinkle expression and tested the same individuals on a spatial JBT with active trial initiation. Eye wrinkle expressions were assessed by a qualitative assessment, i.e., the overall assessment of how "worried" horses ...
Role and Effects of Hippotherapy in the Treatment of Children with Cerebral Palsy: A Systematic Review of the Literature. Cerebral palsy is described as a group of permanent neuromotor-type disorders caused by non-progressive injuries in the developmental stages of the central nervous system, and which have serious repercussions on the quality of life of affected children due to the physical and psychological damage it entails for them. Today, it is the leading cause of physical disability in childhood. Since there is no cure for this disorder, treatment is based on the improvement of symptoms, which is not always achieved through conventional therapies. For this reason, the need arises to investigate other alter...
Interspecific two-dimensional visual discrimination of faces in horses (Equus caballus). In social animals, recognizing conspecifics and distinguishing them from other animal species is certainly important. We hypothesize, as demonstrated in other species of ungulates, that horses are able to discriminate between the faces of conspecifics and the faces of other domestic species (cattle, sheep, donkeys and pigs). Our hypothesis was tested by studying inter-and intra-specific visual discrimination abilities in horses through a two-way instrumental conditioning task (discrimination and reversal learning), using two-dimensional images of faces as discriminative stimuli and food as a p...
Exploratory behaviour towards novel objects is associated with enhanced learning in young horses. The mechanisms underlying individual variation in learning are key to understanding the development of cognitive abilities. In humans and primates, curiosity has been suggested as an important intrinsic factor that enhances learning, whereas in domesticated species research has primarily identified factors with a negative effect on cognitive abilities, such as stress and fearfulness. This study presents the first evidence of a link between object-directed curiosity and learning performance in young horses in two very different learning tasks (visual discrimination and pressure-release). We exp...
Hippotherapy in neurodevelopmental disorders: a narrative review focusing on cognitive and behavioral outcomes. Hippotherapy (HT) is a rehabilitative tool inducing psychological and motor improvements using human-horse interaction. HT provides sensory stimulation to the rider through the rhythmic and repetitive movements of the horse, facilitating communication between patients and healthcare professionals, favoring the establishment of a therapeutic alliance. The purpose of this review is to evaluate the effects of HT treatment on cognitive-behavioral processes in neurodevelopmental disorders. We screened studies published between 2002 and 2020 on PubMed, Scopus, Cochrane, and Web of Sciences databases...
Equine-assisted biographical work (EABW) with individuals in the second half of life: study protocol of a multicentre randomised controlled trial. Equine-assisted therapy is more often practiced with children and adolescents than with the elderly, although individuals in the second half of life could also profit from it. This group, from the age of 50, is characterised by increasing emotional, social, health-related and cognitive changes; a critical life event, such as a neurological illness or loss of a family member, can increase the likelihood of subclinical depression. Individuals who exhibit depressive symptoms not necessarily diagnosed with a major depression may suffer from relevant losses of quality of life (e.g. sleep disorders,...
Unwilling or willing but unable: can horses interpret human actions as goal directed? Social animals can gain important benefits by inferring the goals behind the behavior of others. However, this ability has only been investigated in a handful of species outside of primates. In this study, we tested for the first time whether domestic horses can interpret human actions as goal directed. We used the classical "unwilling versus unable" paradigm: an experimenter performed three similar actions that have the same outcome, but the goal of the experimenter differed. In the unwilling condition, the experimenter had no intention to give a piece of food to a horse and moved it out of r...
Female horses spontaneously identify a photograph of their keeper, last seen six months previously. Horses are capable of identifying individual conspecifics based on olfactory, auditory or visual cues. However, this raises the questions of their ability to recognize human beings and on the basis of what cues. This study investigated whether horses could differentiate between a familiar and unfamiliar human from photographs of faces. Eleven horses were trained on a discrimination task using a computer-controlled screen, on which two photographs were presented simultaneously (32 trials/session): touching one was rewarded (S+) and the other not (S-). In the training phase, the S+ faces were of...
Parental Perception of Changes in Basic Life Needs of Children with Disabilities after Six Months of Therapeutic Horseback Riding: A Qualitative Study. Therapeutic horseback riding (THR) has a positive effect on the physical, cognitive, and psychosocial functioning of children with disabilities. Parents' reports of the effects of THR on their children support professionals in individualizing the THR program. With this qualitative study, we aimed to explore parents' perceptions of changes in the basic life needs of their children with disabilities after six months of THR lessons and to survey parents' explanations for the causes of these changes. The study involved parents of 13 children with disabilities who were enrolled in a six-month THR p...
Medicine and Horsemanship: The Effects of Equine-assisted Activities and Therapies on Stress and Depression in Medical Students. This study examined the use of an equine-assisted brief course module on stress and depression among medical students (n = 28), a demographic known to experience high pressure. Evidence supports that animal-assisted therapies can lead to the improvement of health and quality of life, particularly in terms of cognitive, psychological, and physical benefits. This study used the seven-session Kane Medicine and Horsemanship program; students completed pre- and post-measures one week before and after the course. Participation in the course significantly reduced perceived stress (p: 0.001), depressi...
Horses and zebras: probabilities, uncertainty, and cognitive bias in clinical diagnosis. Medical diagnosis is typically an iterative process guided by integration and synthesis of data into a model of disease. However, facts are not the only inputs into this process. A case of medical mis-diagnosis is presented, in which systematic cognitive bias is considered to have played a role in generating error. Specific cognitive biases are cited, and measures that can be taken to minimize their negative impact are reviewed.
Self-Management Intervention for Attention and Executive Functions Using Equine-Assisted Occupational Therapy Among Children Aged 6-14 Diagnosed with Attention Deficit/Hyperactivity Disorder. Attention deficit/hyperactivity disorder (ADHD), characterized by inattention, hyperactivity, and impulsivity, is currently one of the most common diagnoses given to children. Children with ADHD have a unique cognitive profile that involves difficulties in executive functions (EFs) and in the self-management system of the brain, and are at higher risk for educational failure, social and emotional difficulties, and high risk behavior. The purpose of this study was to examine the effectiveness of self-management intervention for attention and executive functions using equine-assisted occupatio...
[Physiotherapy interventions through hippotherapy in the treatment of cerebral palsy. A literature review]. Cerebral palsy is produced by nonprogressive injury to the developing brain. This lesion produces life-long motor impairments, disturbances in perception, speech, communication, cognition and competence. Physiotherapy is an important part of treatment, and may include hippotherapy, which uses the movement of the horse to stimulate the sensorial, neuromotor and cognitive systems to obtain functional results. Methods: We performed a literature search using distinct databases and the following Keywords: "hippotherapy"; "cerebral palsy"; "children"; "treatment" and "physiotherapy". After applicati...
The neurocognitive gains of diagnostic reasoning training using simulated interactive veterinary cases. The present longitudinal study ascertained training-associated transformations in the neural underpinnings of diagnostic reasoning, using a simulation game named "Equine Virtual Farm" (EVF). Twenty participants underwent structural, EVF/task-based and resting-state MRI and diffusion tensor imaging (DTI) before and after completing their training on diagnosing simulated veterinary cases. Comparing playing veterinarian versus seeing a colorful image across training sessions revealed the transition of brain activity from scientific creativity regions pre-training (left middle frontal and temporal...
