Document Summary
Perception = you perceive the world through many senses. It is a dynamic and integrated process that combines information from sense organs with memories of past experiences, expectation of likely future actions, attention, motivation, and context. Audition: we have to really think about things because, compared to vision, we can"t hear what we see. Clapping hands: change in air pressure that started where she clapped and moved all the way to the back of the room where people heard it. Once air moved> arrives at outer ear > eardrum/tympanic membrane > tympanic membrane vibrates > creates movement of ossicles > movement of fluid in the cochlea. In it is the basilar membrane which is very important to hearing. Such a small part of the body, yet with specificity it can distinguish all sounds in our environment with tonotopy. Specific frequencies resonate at different locations along the basilar membrane.
