Document Summary

The basics: five senses- seeing, hearing, smelling, tasting, touch. Sensation: the detection of external stimuli and the transmission of this information to the brain: sensing the world around you. Perception: the processing, organization, and interpretation of sensory signals: what the brain does with the sensory information. Both occur in all 5 of the senses. Both originate from environmental stimuli: stimulus. Basically anything that interacts with your senses. Physical input physiological changes in a sensory organ. Transduction: process by which physical input neural signals, taking something from your senses and turning it into action potentials, or something your brain can understand. The brain interprets the representation of the light as a sign to continue driving. Sensation: early processing, raw sensory input. Two types of processing: bottom-up processing: Perception based on the physical features of the stimulus. How knowledge, expectation, or past experiences shape the interpretation of sensory information.
