Cognitive information processing
2
A result of several influences Especially: –Learning theory S-R; S-O-R –Computer science/Information processing Turing Intelligent machines –Information theory Shannon/Bell Labs
3
Proposes: Sensory input is transformed into meaning through a series of actions you perform –Mainly in the brain, but not all –The processes are in a relatively invariant order –All people follow the same set of processes of thinking –However, the outcomes can be quite different
4
Four major types of info processing theories Stage theory Depth of processing theory Parallel distributed processing theory Connectionist models
5
Stage theory Argues for three major types of memory –Sensory memory –Short-term memory –Long-term memory
6
Levels-of-processing All information is stored, problem is in retrieval Retrieval is based on the amount of elaboration used in processing of information Perception, attention, labeling, meaning
7
Parallel distributed processing theory Simultaneous processing by several different parts of memory system rather than sequentially
8
Connectionistic theory Information is stored in multiple locations throughout the brain in the form of networks of connections More connections to a single idea or concept, the more likely it is to be stored and retrieved
9
General principles Limited capacity to be actively processed at a given time –Bottlenecks Control mechanism—part of the system’s processing capacity must be assigned to a control mechanism
