Document Summary

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. Transduction: process by which sensory receptors convert energy into neural impulses. Sensory receptors detect and respond to various stimuli (modality speci c) Sensation: vision, audition, gustation, olfaction, the somatosenses. The difference between not being able tp perceive a stimulus and being able to just barely perceive it. The minimum amount of sensory stimulation that can be detected 50% of the time. A psychophysical theory that divides the detection of a sensory signal into a sensory process and a decision process. Assumes there is no single absolute threshold and that detection depends on person;s experience, expectations and alertness. The smallest increase or decrease in a physical stimulus that is required to produce the.
