Notes Sensation and perception are two processes that work together to help us understand and interact with our environment. Sensation refers to the activation of our senses by the physical energy present in our environment. The five senses that we typically refer to are vision, hearing, touch, taste, and smell. Each sense has specialized receptors that are sensitive to specific types of energy. For example, the eyes are sensitive to light, and the ears are sensitive to sound waves. Perception is the process of understanding the sensations we experience. It involves the brain's interpretation of the sensory information received, and it is influenced by our past experiences, expectations, and attention. Energy senses are senses that are activated by a type of energy in our environment. Vision is an energy sense that is activated by light. The process of vision can be broken down into two steps. The first step of vision is gathering light. Light is reflected off of objects and gathered by the eye. The color we perceive depends on two factors: intensity and wavelength. Intensity refers to how much energy the light contains and determines brightness. Wavelength determines the hue or color that we see. The second step of vision involves the structures within the eye. Light first enters the eye through the cornea, a protective covering that helps to focus the light. The light then goes through the pupil, a small opening that is controlled by the iris, which determines how much light gets into the eye by controlling the size of the pupil. After passing through the pupil, the light is focused by the lens through a process called accommodation. The lens is curved and flexible, and as the light passes through it, the image is flipped upside down and inverted. The focused, inverted image then projects onto the retina, which contains specialized photoreceptor cells called rods and cones. In summary, sensation refers to the activation of our senses by the physical energy present in our environment, while perception is the process of understanding these sensations. Vision is an energy sense that involves the gathering of light and the structures within the eye that focus and project the image onto the retina. Understanding these processes can help us to better understand how we experience and interpret the world around us
