Document Summary
Hippocampus, cerebellum, amygdala: hippo- new memories, cerebellum - procedural memory, amygdala - associate emotions to memories (negative ones) Semantic networks and spreading activation: long term stored as network. Nodes - indiv ideas: require that response threshold be met to activate - summation of input signals to reach, spreading activation - when response threshold met, node fires and sends stimulus to neighbors and activate them. I. retrieval - process of finding info stored in memory. Recall, recognition, and relearning: recall - ability to retrieve info. Free recall - retrieving the item out of thin air . Retrieval cues: priming - prior activation of nodes and associations - see something in a setting and associate it w that setting. The role of emotion in retrieving memories: mood dependent memory - recalled when in same emotional state. Forgetting - failure in any of the following steps: paying attention, encoding, retaining info (storage), retrieval.
