PSYC 101 Lecture Notes - Lecture 8: Short-Term Memory, Episodic Memory, Procedural Memory
Document Summary
Information processing theories: brain and computer operations are similar. Information-processing model: operations: input, storage, and retrieval, variety of control mechanisms at each point. Information enters through sensory receptors: attention selects the information to be entered. Information is encoded for next memory stage: some memory is saved, other information is lost or discarded. Sensory register: holds image or experience until processed, can last up to 4 seconds/usually lasts less. Short term memory (stm: usually attention transfers information from sensory register to stm. Q: how long does information last in: usually last less than a minute unless control processes like rehearsal and chunking are used = long-term memory. How can we increase the amount of info in. Rehearsal mental repetition of information: humans have preference from transforming information into acoustic codes or sounds ex: abcdefg . Stm functions: temporary storage of information, serves as working memory, space used for retrieved memories from long term memory.
