Memory- Mental processes involved in acquiring, storing, and retrieving informationII. Stage Model of Memory- Sensory Memoryo Environmental information is registeredo Large capacity for informationo Duration: ¼ second to 3 secondso Attention leads to next step- Short-Term (Working) Memoryo New information is transferred from sensory memoryo Old information in retrieved from long-term memoryo Limited capacity for informationo Duration: approx. 20 secondso Encoding and Storage leads to next step- Long-Term Memoryo Information that has been encoded in short-term memory is storedo Unlimited capacity for informationo Duration: potentially permanento Retrieval leads back to short-term (working) memory- Short-Term Memoryo Maintenance rehearsal: repeating information to keep in working memoryo Capacity: 7+2o Chunking Often involves retrieval of LTM- Long-Term MemoryThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.o Explicit Memory (Declarative Memory) Memory with conscious recall- Episodic Memoryo Events you have experienced- Semantic Memory- General knowledge, factso Implicit Memory (Nondeclarative Memory) Memory without conscious recall- Procedural Memoryo Motor skills, actionso Procedural Memory: Actions, performance of skillso Episodic Memory: Specific events, experiences, time, placeo Semantic Memory: Facts, names, definitionsIII. Forgetting- Decay Theory:o When a new memory is formed, it creates structural and chemical changes in the brain that face over time as normal brain processing- No!o Memories can get stronger over timeo Rate of forgetting decreases over time.o Temporal gradient of forgetting- Interference Theory:o Caused by memories competing with or replacing each othero Retroactive: A new memory interferes with an old oneo Proactive: An old memory interferes with formation of a new one- Reconsolidation: Long-term that occurs after a memory has been retrievedIV. Motivated Forgetting- Undesired memories are held back from awarenessV.
