Document Summary
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. Specific frequencies resonate at different locations along the basilar membrane. Primary auditory cortex -> motor cortex + broca"s area/wernicke"s area. Rate of vibration or changes in air pressure. How to form mental representations of sound (sound waves) Grouping similar sounds together and separating them from others. Sensory/brain process involved in forming mental representations of sound. Principles of sound segmentation resemble principles of visual organization (gestalt psychology) Grouping or separation of a sequence of tones into 2 auditory streams based on separation in time. Gestalt principle of proximity (increasing presentation speed exaggerates the effect of differences in the frequency dimension, i. e. one high melody and the. Grouping or separation of a sequence of tones into 2 auditory streams based on separation in frequency.
