Introduction
Senses are used to help animals understand their environment. There are several sensory organs that contain receptor cells which respond to certain stimuli. The stimuli for the receptor cells come in the form of energy. The different cells respond to specific energy forms whilst being able to ignore others (OCR, 2002).
Mammals are very similar to each other in terms of the senses they use to understand the environment, although different species use the senses in different ways. For many animals, sight is the main sense to be used. In the domestic dog, (Canis lupis familiaris) the eyes are placed at the front of the head as naturally this would allow them to locate prey in front of them. In some breeds of dog, for example hounds

The seesaw is an obstacle that requires the dog to run up the slope, and pause in the middle to allow the ramp to tip before the dog can run down. For this, the dog must be able to find the right point to pause and still balance on the narrow ramp without it tipping backwards. When running through the tunnel on the course, the dog may not be able to see the other side, and would not be able to see any hand signals given by the handler. At this point, the dog relies strongly on its other senses to get through the tunnel. Jumps may also be included in the course, which require the dog to judge when to set off to be able to clear the jump without knocking down the pole. This will rely on the dog being able to see the jump from a distance, and focus its field of vision onto the area around the jump (Kennel Club, …show more content…
A dog’s sense of smell is far more acute than a humans’, partly due to the difference in the way they function. A dog’s nose contains more olfactory receptors than a human’s that give it a more developed sense of smell (Tyson, 2012).
A dog would be able to smell where another dog has been and so could use this to follow the same course during the agility competition. Dogs are able to recognise different human scents, and so would be likely to recognise the scent of their handler over the scent of other people (Schoon, 1996).
Studies have also shown that not only is a dog able to identify a person by smell, they are able to recognise the scents from different areas of a person when mixed with other samples, for example, a dog could recognise a scent from the hand, or the elbow of the same person when given a selection from different people (Schoon et al. 1994). It has even been found that in some cases, dogs have been able to distinguish between human twins, even when the scent is almost identical (Kalmus, 1995). This shows the range of scents the dog could detect when completing the course, that they must ignore to focus on overcoming the
Unusual violent behavior can lack of exercise and nutrition. Or a dog's aggression may just simply come from genetics or hormones (“CAUSES OF DOG”). A dog can smell the hormones that human's emotions give off. So if a dog senses that someone is afraid it will try to intimidate that person (“Does My Dog Know”). It is important to stay calm around dogs, especially around the ones who are not familiar with you. Dogs can also sense if someone is afraid through their body language. If a person is moving nervously around
Scent is part of the five senses that are developed when an infant is still in the mother’s womb. It is processed by a part of the brain that correlates with memory, so at a young age an infant could differentiate who their mother is by scent. Odor is a sign and olfactory condition (Waskul & Vannini, 2008). As someone gets older they begin to develop scents they like and dislike. There are also scents that people find attractive and unattractive. When meeting another individual for the first time a human’s first instinct is to smell them without realizing it. For instance, have you ever sat by someone or hugged someone who smelled good or bad? If so, many people tend to associate the scent with attractiveness or unattractiveness depending on the level of smell. There have been many studies indicating that there is a strong correlation between odor and attractiveness. Although the scent is a universal and an undetectable smell it can influence the level of perceived attractiveness of another person.
Dogs are common throughout the world, either as a domestic pet, a protector on a farm, or an assistant for hunting amongst others. Regardless of the reason for having a dog, most people have either owned one for themselves or have known somebody who has owned one at some point in their life. Despite the relative normality of having a dog in your life in one way or another, the reasons for dogs coming into existence are not common knowledge among most people. Throughout a great portion of mankind’s history, dogs have been an essential part of life. The truth is, dogs were actually created in part by man.
Based on what I have observed I would conclude that vision and touch are the two sensory systems most important for the animal to function successfully in its environment. I believe this based on the surrounding nature of the stables, pasture, number of horses and farm life. There are 19 other horses and 5 staff aside of the stable owner. A horse in that respect needs to have vision of what is going on in its surroundings and personal space. Likewise horses rely on touch and the ability to feel to keep their selves from harm and to gain more awareness of their surroundings.
Animal spirits are a product of irrational behavior and are a major driving force in the economy. Intuitive then is the notion that animal spirits are also heavily involved in the process of economic boom and bust cycles. This much is straightforward and in reality seems to be the case. Animal spirits, which were initially defined by John Maynard Keynes, characterizes a variety of exogenous variables that could not be accounted for in the mainstream rational economic theories of the time. This definition was later reclassified by Akerlof and Shiller in their title book and provided some of the mechanics behind seemingly irrational behaviors. Akerlof and Shiller described and highlighted five specific features of animal spirits that affect the
Sensation refers to the process of sensing what is around us in our environment by using our five senses, which are touching, smell, taste, sound and sight. Sensation occurs when one or more of the various sense organs received a stimulus. By receiving the stimulus, it will cause a mental or physical response. It starts in the sensory receptor, which are specialized cells that convert the stimulus to an electric impulse which makes it ready for the brain to use this information and this is the passive process. After this process, the perception comes into play of the active process. Perception is the process that selects the information, organize it and interpret that information.
There are numerous types of non-verbal communication, yet one of the most underestimated is the olfactics, or our sense of smell. It is generally assumed that the greater portion of the sensory world and communication is experienced through the auditory and visual senses. However, the underrated impact of our sense of smell is increasingly becoming acknowledged as a powerful communicator. The human nose has the capacity to differentiate between 1
Visual perception and visual sensation are both interactive processes, although there is a significant difference between the two processes. Sensation is defined as the stimulation of sense organs Visual sensation is a physiological process which means that it is the same for everyone. We absorb energy such as electro magnetic energy (light) or sound waves by sensory organs such as eyes. This energy is then transduced into electro chemical energy by the cones and rods (receptor cells) in the retina. There are four main stages of sensation. Sensation involves detection of stimuli incoming from the surrounding world, registering of the stimulus by the receptor cells, transduction or changing of the stimulus energy to an electric nerve impulse, and then finally the transmission of that electrical impulse into the brain. Our brain then perceives what the information is. Hence perception is defined as the selection, organisation and interpretation of that sensory input.
It is difficult to correctly identify each dog by breed- some are mixed and tests are expensive.
You will realize that dogs are normally curious by nature and wants to learn something new. Dogs can also be instinctive at times. Training them will go a long way in ensuring that your dog uses its brains
With each of our senses (sight, smell, touch, taste, and hear), information is transmitted to the brain. Psychologists find it problematic to explain the processes in which the physical energy that is received by the sense organs can form the foundation of perceptual experience. Perception is not a direct mirroring of stimulus, but a compound messy pattern dependent on the simultaneous activity of neurons. Sensory inputs are somehow converted into perceptions of laptops, music, flowers, food, and cars; into sights, sounds, smells, taste ...
People have started to make remarks of the resemblance between dogs and their owners, and from what we have found, it is usually noticed at dog shows and from strangers passing by in the streets. There are two factors that could make the owner and the dog similar. One would be people selecting dogs that are like them, and people who select dogs which features start to change and become similar to them over time. As a comparison to animals and their dogs, there is evidence that couples look physically similar after 25 years rather than people who have recently been wed. In the research we have conducted, we have found that purebred dogs have a greater resemblance than people who own non purebred dogs.
Perception, at most times, is a credible way to assess the world around us. Without perception, we would not know what to do with all the incoming information from our environment. Perception is constructed of our senses and the unconscious interpretations of those sensations. Our senses bring in information from our environment, and our brain interprets what those sensations mean. The five most commonly accepted senses -- taste, smell, hearing, sight, and touch -- all help create the world around us as we know it.

In conclusion, there are various similarities and differences that dogs and cats hold to one other. This compare and contrast between the two animals is perceived in different ways. Some may think more highly of cats due to their intelligence, while others will choose a dog any day because of their companionship attributes. It primarily relies on the personality and desires of a
