Document Summary

Exposure to one stimulus or multiple stimuli influences responses to another stimuli. The take home message of our priming demonstration: Perception results from both top-down and bottom-up processing. = sensory info plus other info from previous experience or larger context. Perception experiences: but we don"t process stimuli piece-by-piece, in isolation from our previous and our other senses. It"s not a chaotic mess, it"s an integrated whole. Integration of info from different senses by the nervous system. Visual dominance effect: generally speaking, when we get conflicting info from two senses, as humans, vision typically wins; vision is our most important sense. Multisensory integration: speech perception: to process speech well, we often need both auditory and visual modalities. We must hear speech sounds, but also helpful to see mouth. It turns out that visual information you get from seeing a person speak, changes the way you hear the sound.
