Document Summary

Discussed in terms of relative sensitivity; high sensitivity being easiest to recall. Retrieval is aided by semantic networks, which link related information together like a concept map. The spreading activation principle explains how information is retrieved in semantic networks: when one concept becomes activated in the network, other related concepts become activated also.

Involves retrieving stored information using the least possible number of cues encountered similar stimuli. Recalling the correct information given a list of alternatives. Retained information can be quantified as a savings score. Savings score = (time for original learning) (time for relearning) x100 (time for original learning) Each time an ltm is remembered, it is reconstructed. Current emotions when recalling something can make people more likely to add emotion to the memory. People can also feel as though they were in attendance of an event, if they are told a story with sufficient detail.
