Document Summary
Process through which the senses detect visual, auditory, and other sensory stimuli and transmit them to the brain. Sensory organs play role in picking up sensation. Process by which sensory info is actively organized and interpreted by the brain. The difference between not being able to perceive a stimulus and being able to just barely perceive it. Minimum amount of sensory stimulation that can be detected 50% of the time. We know when things are there, most of the time we just ignore it. The smallest increase or decrease in a stimulus that is required to notice a difference. Difference that is detectable 50% of the time. Become less sensitive to unchanging sensory stimulus over time. Individual components of stimulus detected by sensory receptors. Bits of info transmitted to areas of brain to be combined and assembled into a unified whole. We find meaningful links between the individual elements taken in by our sensory receptors.
