What is memory?
A biological hard drive of information stored in the brain which makes up our identity, as well as our preferences and relationships or immediate intelligence.
What is the three step chain in how information is stored and used in our memory?
- Encoding: The process of how information is initially learned.
- Storage: The process of maintaining information over a short or long period of time.
- Retrieval: The process involved in recovering information from a memory to produce a response.
What is a search metaphor?
It describes the processes involved in memory using terms and phrases that relate to searching in physical or virtual space. It can include:
1. Reliving moments in the memory
2. Bringing something to the front of your mind
3. Finding a solution
What is a reconstruction metaphor?
To primarily use memory to construct together a useful response using both what we know and the situation around us.
What are flashbulb memories?
Vivid, detailed, and long-lasting recollections of learning about a surprising or shocking event, often including details about where you were and what you were doing at the time
What does it mean when we explain our memories to be “reconstructive”?
To reconstruct memories off of available information. The information used to recall a situation or memory at hand should be accurate and is incredibly important in relation to our long lasting memory, which can include visual or sensory information.
What is the Modal Memory Model?
A model that describes our process of retaining information. It occurs in:
1. Sensory Input becomes Sensory Memory
(This can be forgotten. If given attention, the steps continue:)
2. Immediate Memory
(Which can be forgotten. If not forgotten, it results in either a reaction, or is encoded into long-term memory:)
3. Long-Term Memory
(Indefinite storage which can be forgotten. Retrieval steps back to immediate memory.)
What is sensory memory?
A system that keeps information translated by the senses briefly active in an unaltered or unexamined (unprocessed) form.
What are two forms of sensory memory?
- Iconic memory: A visual form of sensory memory (icons, visuals, graphics)
- Echoic memory: An auditory form of sensory memory (echoes, sounds, lyrics)
What is immediate memory?
A system that actively holds on to a limited amount of information so that it can be manipulated and processed. Known as short-term or “working” memory as it is the contents of consciousness.
How can information be stored in short term/immediate/working memory? What are some forms?
- Visually: Images
- Phonologically: Sounds
- Semantically: Meaning
- Action: Motor patterns
What are the limits of short-term/immediate/working memory?
There is a limited capacity for the amount of information that can be at attention at any given time as well as the limit of manipulation of said memory. Information at hand lasts about 20 seconds.
What are some characteristics of short-term/immediate/working memory?
- Representation
The kind of information a memory system contains. - Duration
How long a memory system can contain information before it is forgotten. - Capacity
How much information can be held in a memory system at any time.
How can short-term/immediate/working memory be forgotten?
- Decay: The information fades over a span of time.
- Interference: Loss of information due to competition with other information. Or, multiple points of attention that overrule other points of information at the time.
What is the meaning of duration for a memory system?
How long a memory system can contain information before it is forgotten. It can depend as we see a drop from as little as 3 seconds, but it can persist until 20 seconds. This is wholly dependent on the individual.
This can be indefinitely remembered as long as it is rehearsed.
What is the meaning of capacity for a working memory system? What about memory span?
How much information can be held in a memory system at any one time. Capacity is usually considered to be whatever you can rehearse in two seconds, typically 7 +/- 2.
Memory span is the number of items that can be kept active in immediate memory at one time.
What is chunking?
Grouping familiar stimuli for storage as a single unit.
Ex.
IHAT ESTU DYIN G > I HATE STUDYING
What are some patterns that have commonly been identified when we remember lists?
- Serial Position Effect
Describes the relationship between a word’s position in a list and its probability of recall. - Primacy Effect
The tendency to remember things at the beginning of the list. - Recency Effect
The tendency to remember things at the end of the list (most recently exposed to).
What is Long-Term Memory?
Our “library” of memories. Durable storage of past events and learned knowledge, which has a large storage capacity. This can endure for a lifetime, or be permanently stored.
What is encoding?
Forming a new memory code. How we initially learn information. Brains need to overcome the encoding problem to initiate the process of bringing information into our memory (put it into storage).
How can we enrich encoding memory?
- Elaboration
Linking a stimulus to other information at the time of encoding. (Thinking of examples) - Visual Imagery: Creation of visual images to represent words to be remembered (easier for concrete objects)
- Self-referent Encoding: Making information personally meaningful.
What are some types of Long-Term Memory?
- Procedural Memory
Memories whose contents pertain to how something is done. - Priming
Ability to identify a stimulus more easily or more quickly after we’ve encountered similar stimuli.
What are some times of Long-Term memory damage? (Amnesias)
- Anterograde Amnesia
The loss of ability to assimilate and retain new knowledge. - Retrograde Amnesia
The loss of memory of events that have happened in the past.
What is an example of an encoding strategy?
Spaced practice is better than massed. For example, studying for 30 minutes across 4 days rather than studying 2 hours in one day. Spacing works for improving episodic and semantic memory, and for procedural memory.
