PSYA01H3 Chapter Notes - Chapter 4: Stirrup, Microvillus, Somatic Nervous System
Document Summary
Some unusual perceptional events are varieties of synesthesia, the perceptual experience of one sense that is evoked by another sense. For some synesthetes, musical notes evoke the visual sensation of color. Other people with synesthesia see printed letters or numbers in specific, consistent colors (always seeing the digit 2 as pink and 3 as green, for example). Still others experience specific tastes when certain sounds are heard. So, synesthesia is neither an isolated curiosity nor the result of faking. In fact, it may indicate that in some people, the brain is wired differently than in most, so that brain regions for different sensory modalities cross-activate one another. Psychologists know, however, that sensation and perception are two separate activities. Sensation is simple stimulation of a sense organ. It is the basic registration of light, sound, pressure, odor, or taste as parts of your body interact with the physical world.
