Unit 7 A Lecture Notes ‘Memory’ The Phenomenon of Memory Memory is Flashbulb Memory is What are the stages of memory? How is memory like a computer? Information Processing Three stage model of memory: 1. 2. 3. Problems with the model: 1. 2. 3. Encoding: the processing of _____________________________________ Storage: the retention of ____________________________________ Retrieval: process of getting information _____________________________ Sensory Memory o Working Memory o Short-term memory o o Long-term Memory o Maintenance Rehearsal o Long term memory: Once information passes from sensory to working memory, it can be encoded into long term memory. o o Unlimited capacity o Duration-thought by some to be permanent A Simplified Memory Model Copy the model below: Encoding o Automatic Processing o Unconscious encoding of incidental information o Well-learned information o o Effortful processing o o Rehearsal o o Forgetting How much do people forget in 30 days? Encoding Semantic Encoding o o Acoustic Encoding o o Visual Encoding o Imagery o o Mnemonics o o Chunking o o Hierarchies o Storage- Short Term Memory Storage- Long Term Memory How does storage work?
