Memory

Memory. Declarative- factual information handled by hippocampus & areas of the cortex Episodic - personal facts and experiences Like an autobiography Maybe unique to humans Ex: first day of school Semantic - general, factual knowledge Ex: knowing the state capitals Like an encyclopedia.

  1. Memory

  2. Declarative- factual information handled by hippocampus & areas of the cortex Episodic- personal facts and experiences Like an autobiography Maybe unique to humans Ex: first day of school Semantic- general, factual knowledge Ex: knowing the state capitals Like an encyclopedia NonDeclarative/Pro-cedural- actions and skills (muscle memory) Little conscious awareness Ex: riding a bike Performance decreases if you think too much Doesn’t decline much Cerebellum and amygdala Memory Systems

  3. 3 Key Processes of Memory Encoding Storage Retrieval Encoding- forming a memory code Storage- maintaining encoded information over time Retrieval- recovering information from memory stores

  4. Encoding • Encoding Techniques • Elaboration • Visual Imagery

  5. Storage Information Processing Theory- incoming information passes through 2 temporary areas of storage (sensory & short-term) and then is transferred to long-term storage Sensory Short Term Long Term (working)

  6. Sensory Memory • Allows sensation to linger for a brief moment after stimulus is presented • Less than a second • Ex: afterimage • Experiment with Trigrams!

  17. Short-term memory (STM) • Limited capacity (7-9 items) • Limited duration (up to 20 sec.) • Rehearsal- Repeating information • causes STM to last longer • Interference- new info pushes out old • EXPERIMENT! • Chunking- combining separate items • EXPERIMENT! • Serial-Position Effect (primacy/recency)- better recall of info from beginning and end of list

  18. Long-Term Memory (LTM) • Unlimited capacity over long periods of time • Flashbulb Memories- vivid & detailed recollections of momentous events in our life
