PSYC*2140 Study Guide - Midterm Guide: Artificial Neural Network
Document Summary
Emphasis on: how info flows through organism, draws analogy between human cognition + computerized processing, info stored symbolically, info processed in stages + stored in specific places while being processed. Stages: receive, store, recode, transform, retrieve, + transmit: thought of systems of interrelated capacities, nature of representations + nature of processes that operate on representations. Typical info processing model ex: receive, detect in. Olfactory (smell) sensory measure: recognize, store in stm, rehearsal, store in ltm. Neural networks: neuron-like elements code patterns of activation across large population of such elements. Emphasis on network of connections among a lot of simple processing units: units connected by weights that are modifiable by learning. Negatively weighted leaders to inhibition: items like letter, word or meaning are represented by pattern of activation. Don"t need to hypothesize central processor to direct flow of info. Patterns of activation are responsible for various cognitive processes. Cognition understood by uncovering basic mechanism or processes underlying cognition.
