LECTURE 6: MEMORY
Competing memories, how we form and store memories. Schafteron, and Schriffen. Craig and
Lockhart theory: information process and elaboration model. If an emotion attached to an event,
we are more likely to remember an event, when emotion is evoked again more likely to
Encoding: transforming information into a form that can be entered and retained in the memory
Storage: retaining information in memory so that it can be used at a later time.
Retrieval: recovering information stored in memory so that we are consciously aware of it.
Sensory memory: limitless capacity. Filtering by attention. Duration: half a second to a second.
Working memory: around 7 chunks of information capacity. Duration: 20 seconds.
Long term memory: unlimited capacity. Duration: unlimited.
Info processing theory to describe memory. Good for artificial intelligence ie/computer.
Encoding and retrieving at the same time-sophisticated process. Filtering out other things.
Automatic: interpreting changes in sound waves and meaning and Effortful: effortful
concentrating on speech.
Automatic process: Habituation andAssociative learning-two types: operant and classical
Effortful processing requires attention and conscious effort
Types of LONG-TERM memory (Tolving): explicit: memory with awareness; info can be
consciously recollected; also called declarative memory. Episodic:events you have experienced
(internal diary), most sophisticated, tied to personal experience. Explicit because you can
actively declare your answers and semantic: general facts, not tied to personal events, does not
depend on typing the item to your past. Can use explicit memory to directly respond to a
Implicit: memory without awareness; memor
