Document Summary

A dynamic and integrated process that combines information from sense organs with memories of past experiences, expectations of likely future actions, attention, motivation, and context. Today, we will consider auditory contributions to perception and interactions between perception and cognition. If i clap my hands, at this location at a specific point in time, some air has been displaced creating sound waves that will travel from the location until the ear and can continue to travel further. Physical properties of sound: displacement of air over time and distance--> frequency, magnitude of how much air is going to be displaced---> amplitude. When the 2 properties are combined together, we perceive them as loudness. , In the inner ear, the is change of signal from air in vibration to movement of fluids. The fluid in the cochlea starts to move when the sound reaches the inner ear. On the basilar membrane, there are hair cells, When the fluid moves, the hair cells moves.
