Document Summary

Module 18: basic concepts of sensation and perception. Sensation the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment. Perception the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events. Conversion of one form of energy into another. In sensation, the transforming of stimulus energies, such as sights, sounds, and smells into neural impulses our brain can interpret. All of our senses (1) receive sensory stimulation, often using receptor cells (2) transform the stimulation into neural impulses (3) deliver the neural information to the brain. Psychophysics the study of relationships between the physical characteristics of stimuli, such as their intensity, and our psychological experiences of them. The minimum stimulus energy needed to detect a particular stimulus 50% of the time. Usually to detect light, sound, touch, taste and pressure.
