Document Summary

Transduction: sensory receptors translate information from stimuli (senses) into nerve impulses. With synesthesia, there is a deficit in neural inhibitory processes in the brain that ordinarily keep input from one sensory modality from. Overflowing" into other sensory areas and stimulating them. Sensation: stimulus-detection process by which our sense organs respond to and translate environmental stimuli into nerve impulses that are sent to the brain. Perception: making sense" of what our senses tell us- the active process of organizing this stimulus input and giving it meaning. The sensory equipment of any species is an adaptation to the environment in which it lives. Human sensory systems are designed to extract from the environment the information that we need to function and survive. Absolute threshold: the lowest intensity at which a stimulus can be detected correctly 50% of the time; the lower the absolute threshold, the greater the sensitivity.
