The structural design and sensory capabilities inherent in the equine brain.

Equines have evolved with a sensory apparatus tailored for the expansive detection of motion and a wide-ranging perspective, contrasting with humans who excel in observing fine details and estimating the space between objects.

Jones clarifies the process by which both horses and people form their visual understanding by merging visual signals with the knowledge already present in their minds. Despite this, when examining the functional processes of these systems, there are substantial differences between horses and humans. The widely spaced eyes of a horse feed information to a brain that excels in initiating actions rather than in-depth analysis. Human vision is characterized by forward-facing eyes that provide a slower transmission of visual information to a brain focused on evaluation and decision-making.

Horses have large eyes situated on the sides of their heads, granting them a 340-degree view, unlike humans who can only see within a 90-degree scope.

The author emphasizes the horse's visual system's evolutionary progression, which broadens their panoramic vision, thereby improving their capacity to detect predators over wide, open grasslands. Horses have a wide field of view, save for a small blind spot directly behind them. Equines possess an expansive field of vision that allows them to detect subtle movements which humans frequently overlook because our vision is more narrowly focused to the front.

Context

• The placement of a horse's eyes on the sides of its head is a common trait among prey animals, allowing them to have a broader field of view to spot potential threats from various angles.
• The blind spot is a key consideration in equine safety and training practices, as it affects how horses perceive their environment and react to stimuli.
• This trait is part of their flight response, a primary survival mechanism that has been honed over millennia.
• The ability to focus on faces and interpret subtle expressions is enhanced by our forward-facing eyes, playing a crucial role in human social interactions and communication.

Horses are capable of discerning fine details at distances where human observation of the same details would be considerably less or more effective.

Jones points out that despite horses having the most sizable eyes of land-dwelling mammals, their capacity for discerning fine details is relatively restricted. To clearly make out the finer details, horses must be much closer to an object than humans. While it might appear as if a horse is carefully examining a field, the truth is that this action is a compensatory measure for its relatively poor vision. As we approach unfamiliar objects, it's crucial to remember this distinction when navigating jumps and employing implements. What seems obvious to us may not be as apparent from the perspective of the horse.

Practical Tips

• Create a visual art project that captures the essence of having large eyes. Use mixed media, such as photography and painting, to depict scenes from a perspective that emphasizes breadth and detail, representing the expansive view a horse might have. This can be a fun way to appreciate the unique visual capabilities of horses and express it creatively.
• Create a visual journal where you document the fine details you observe in daily life that a horse might miss. Use sketches, photographs, or written descriptions to capture these details. Over time, this journal can serve as a personal reminder of the richness of human perception and the importance of paying attention to the small things in life.
• You can enhance your observational skills by practicing a "field examination" exercise similar to how horses survey their environment. Start by choosing a familiar outdoor space and spend a few minutes each day scanning the area with intention, noting new details each time. This could improve your attention to detail and situational awareness.
• Experiment with different lighting conditions when playing fetch or other games with animals to see how they adapt. Try playing in bright sunlight, at dusk, or under artificial lighting to observe how the animal's performance changes. This could help you better understand the impact of light on animal vision and adjust your approach when working with them in different environments.
• Enhance empathy by engaging in role-reversal scenarios. Pair up with a friend or family member and discuss a recent event or topic. First, each person shares their own viewpoint. Then, switch roles and argue from the other's perspective. This activity can reveal the nuances in understanding and interpreting situations, akin to realizing that what's obvious to you may not be to someone else, or a horse.

Equine vision is limited in focusing on objects that are close due to the weakness of their ciliary muscles.

Unlike horses, humans have the ability to focus their sight more precisely. The author points out that horses, unlike humans, have less developed ciliary muscles, limiting their capacity to focus on nearby objects. The muscles are vital in changing the shape...

Horse Brain, Human Brain Summary The foundational concepts and processes that govern how horses learn.

Horses have the capacity to learn through making associations and systematically excluding alternatives, but they do not have the capability for intricate anticipation or the analytical reasoning that distinguishes human thought.

The author highlights the extraordinary ability of horses to retain and learn information, even though their cognitive processes for acquiring knowledge are distinct from human approaches. The cognitive disparities between us can foster thrilling and fulfilling partnerships, though they also frequently result in disagreements. Numerous mistakes in training arise from the mistaken assumption that horses and humans share identical cognitive functions. Let's explore the neurobiological processes that facilitate equine learning and examine ways to tailor these processes for the mutual advantage of both horse and rider.

Horses quickly form associations between cues and their consequences, which can be either beneficial or harmful.

Jones emphasizes how swiftly horses form connections, associating cues, behaviors, and consequences throughout their learning process. Equines are particularly sensitive to various forms of reinforcement, including both...

Horse Brain, Human Brain Summary Investigating the distinct neurological processes of information handling in horses and humans.

Equines lack the advanced prefrontal cortex that provides humans with the capacity for abstract reasoning, strategic planning, and evaluating circumstances.

The book often highlights the substantial distinctions between the area responsible for executive functions in equine brains and the analogous region in human brains. Horses do not possess the ability to reason like humans, nor can they anticipate future events or evaluate potential consequences.

A horse's cognition is primarily molded by immediate sensory perceptions, reacting on instinct to its environment without deliberating on possible consequences.

The book describes how, due to their history as prey animals, horses inherently and emotionally respond swiftly to perceived dangers, rather than with a slower, more calculated approach. Equine brains possess an extraordinary sensitivity to sensory stimuli, especially those related to motion and smell, which allows them to respond with rapid and instinctive actions. The human brain is inherently structured to devise strategies, examine details, and control impulsive responses.

Context

• The lack of deliberation in horses' responses is not indicative of a...
