Document Summary

After working through this lesson"s material, you should be able to: Describe how the structure of our visual system affects the way we interpret the world around us. This week, we will cover your sense of vision how your eye works to sense light, and how your brain takes this sensory information and perceives objects in particular locations, colours, and motion. Describe the visual system from eye to cortex. Describe how sensory information is translated by our visual system into psychological characteristics. The adequate stimulus (a type of physical energy to which a sensory receptor is especially tuned) for vision is light. So, to understand vision, we must first understand the physical characteristics of light. Light is a form of electromagnetic energy (as are x-rays, ultraviolet, and infra-red radiation). The electromagnetic radiation to which we are sensitive is a very small part of the electromagnetic spectrum. Light is made up of particles, called photons (particles that transmit light).
