Document Summary
Sense: a system that translates outside information into activity in the nervous system (smell, hearing, sight, etc. ) Sensation: raw information from the senses (involves accessory structures and transduction) Perception: the process of making sensations into meaningful experiences. Sensation: feeling a touch on your mouth. Perception: knowing that you have been kissed. Sensory receptors respond best to changes in energy. Adaptation is a decreasing responsive to constant stimulation over time. Coding translates the physical properties of a stimulus into patterns of neutral activity. Coding conveys intensity and location and interprets what just happened. Accessory structures: structures in sensory systems that modify an incoming stimulus. Transduction: the process by which an incoming stimulus is converted to neural signals. A mathematical model of the factors affecting a person"s detection of a stimulus. Sensitivity: ability to discriminate a stimulus from its background. Influenced by internal noise, intensity of stimulus, and capacity of one"s sensory system.
