Document Summary

Mental operations are divided into separate modules. Each is domain-specific: processes specific types of information only (semantic, articulation) Information encapsulation (information flows in a uni-directional way: each module only processes data in a bottom-up fashion. Localization of function: each module is isolated to a specific brain region (brain region that"s taking care of the type of cognitive information) Language is processed using separate mechanisms than other cognitive abilities. High-level processing: memory, prior knowledge, context. Bottom-up information: perceptual information is passed to higher levels, but not the other way around. Top-down information: perceptual effects are influenced by higher-up processes, * if we only use top-down, we wouldn"t be using sensory information (hallucination) Parallel distributed processing: mental processes reflect how the brain works. Basic unit of processing in the brain: the neuron (either firing or not firing) Simple processing units ( nodes : have activation like real neurons. Connected to each other into a network.
