    The document provides an introduction to the psychology of perception. It discusses what can be perceived through our senses including color, form, texture, space, movement, speech, temperature, and pain. It distinguishes between sensation, which is the psychological experience due to stimulation of receptors, and perception, which allows us to interpret sensory information through biological, psychological and cognitive processes. The key stages in the process of perception are described as detect, discriminate, recognize, and identify. Top-down and bottom-up processes are involved, and principles of perception discussed include that it depends on previous experience, is influenced by context, and aims to create order and meaning from our surroundings, though it is not always stable as shown through visual illusions.
