Perception of physical world through the brain. Introduction: Physical world has the light and sound of different wavelengths and frequencies. The sounds, textures and colors are perceived with the help of sensory receptors in the eyes and ears, which convey the information to the brain. These receptors act as energy filters which change the various forms of energy in the real world into the nerve impulses energy. This in turn, gives rise to different forms of sensations that help us relate to the physical reality, even if it is indirect or incomplete.

Physical world has the light and sound of different wavelengths and frequencies. The sounds, textures and colors are perceived with the help of sensory receptors in the eyes and ears, which convey the information to the brain. These receptors act as energy filters which change the various forms of energy in the real world into the nerve impulses energy. This in turn, gives rise to different forms of sensations that help us relate to the physical reality, even if it is indirect or incomplete.

Expert Solution & Answer

Explanation of Solution

Human perception of the reality is limited by the ability of sensory receptors for example, the same impulse received by the auditory and optic nerve will be perceived as the sound and sight respectively. In case of vision, the environment has Xâ€“rays, electromagnetic waves and radio waves yet; humans are only able to perceive the visible light with seven colors. This is hence, the perception of light in the physical world, which is incomplete.

Another example is human perception of cold, which happens with the help of sensory receptors in the brain that sense different levels of heat. In the real world, there are only degrees of heat. These two functions are evolutionary adaptations that help us cope with changes in the environment for example, dressing appropriately, if it gets colder and protecting ourselves with the help of sense of sight.

From a biological perspective, how do our senses monitor our body's position and movement? Discuss factors which may influence our vestibular senses. Include a relevant example. Please include references.

Define sensation and perception. Do we have direct contact with our world, or is the world as we know it filtered through our senses? How does the way that we perceive the world influence our mental processes and behavior? Do you think that what we perceive is actually “out there,” or is it what our brain perceives? In other words, can we be mistaken about what we see?

Which statement about color perception theory is true? The mechanisms involved in opponent-process theory take place earlier in the perceptual process than those involved in trichromatic theory. The processes proposed by both trichromatic theory and opponent-process theory take place in the primary visual cortex. Trichromatic theory and opponent-process theory are both strongly supported by behavioral and physiological evidence. Recently, trichromatic theory has overtaken opponent-process theory as the best explanation of color and hue perception.
