Memory is any indication that learning has persisted over time
Several different models, or explanations, of how memory works have emerged from memory research. Two of the most important models: the three-box/information processing model and the levels of processing model. Neither model is perfect.
Three Box model proposes the three stages that information passes through before it is stored:
Sensory memory - split-second holding tank
- the information your senses are processing right now is held in sensory memory
- less than a second
- George Sperling did experiments, showed iconic memory – a split-second perfect photograph of a scene
- Other experiments indicate echoic memory – split-second memory for sounds
- Most of the information in sensory memory is not encoded
- Selective attention determines which sensory messages get encoded
- memories we are currently working with
- temporary, they usually fade in 10 to 30 seconds
- capacity is limited on average to around seven items
- Events are encoded as visual codes, acoustic codes, or semantic codes
- Capacity can be expanded through chunking
- Mnemonic devices- memory aids, really examples of chunking
- Rehearsal or simple repetition can hold information in short-term memory
- permanent storage
- capacity is unlimited
- memories can decay or fade
- stored in three different formats
Episodic memory – memories of specific events stored in a sequential series of events
Semantic memory – general knowledge of the world stored as facts, meanings, or categories rather than sequentially
Procedural Memory– memories of skills and how to perform them, These are sequential but might be very complicated to describe in words.
Memories can also be implicit or explicit
Explicit – also called declarative – conscious memories of facts or events
Implicit – also called nondeclarative- unintentional memories that we might not even realize we have
LEVELS OF PROCESSING MODEL
This theory explains why we remember what we do by examining how deeply the memory was processed or thought about. Memories are neither short- nor long-term. They are deeply (or elaboratively) processed or shallowly (or maintenance) processed.
According to the levels of processing theory, we remember things we spend more cognitive time and energy processing. This theory explains why we remember stories better than a simple recitation of events and why, in general, we remember questions better than statements.
- getting information
- two different kinds: recognition and recall
There are several factors that influence why we can retrieve some memories and why we forget others.
- Primacy effect– more likely to recall items presented at the beginning of a list
- Recency effect- ability ot recall the items at the end of a list
- Context - semantic network theory
- Flashbulb memories
- Mood-congruent memory- ability to recall a memory is increased when current mood matches mood when stored
- State-dependent memory-
Constructive Memory – false memories, leading questions can easily influence us.
One cause is decay, because we do not use a memory or connection to a memory for a long time. Relearning effect indicates that it isn’t entirely gone
Another factor is interference, two types
- Retroactive interference – learning new information interferes with the recall of older information
- Proactive interference – older information learned previously interferes with the recall of information learned more recently
How memories are physically stored in the brain.
- the hippocampus is important in encoding new memories. Damage can cause anterograde amnesia (can’t encode any new memories)
- long-term potentiation- studies of neurons indicate that they can strengthen connections between each other through repeated firings, this might be related to the connections we make in our long-term memory
