How is memory defined?
the persistence of learning over time through the
ENCODING, STORAGE, and RETRIEVAL of
information
Research on memory’s extremes has helped us understand how memory works.
Some disorders, such as Alzheimer’s disease, slowly STRIP AWAY memory.
At the other extreme are people who
would WIN gold medals in a MEMORY Olympics.
Alzheimer’s disease
a progressive NEURODEGENERATION and fatal condition
memory degeneration
Alzheimer’s begins with difficulty with remembering new info/ progress into inability to do everyday tasks
LOST of MEMORY, SPEECH COMPLEX
Solomon Shereshevskii
could repeat up to 70 digits, if they were read about 3 seconds apart in an otherwise silent room.
He could recall digits or words backward as
easily as forward.
How is memory measured?
recall
recognition
relearning
Recall
retrieving information that is NOT currently in your CONSCIOUS awareness but that was learned at an EARLIER time
Recognition
IDENTIFYING items PREVIOUSLY learned
Relearning
Learning something more QUICKLY when you learn it a SECOND time
Recall testing
fill-in-the blank short answer, or essay prompt
Recognition testing
Multiple choice/matching
Relearning testing
Studying for a final exam
Recall in life events
Telling friend about time you won goldfish at the carnival
Recognition in life events
Seeing brand of cereal and recognizing it from commercial
Relearning in life events
traveling to Costa Rica and using Spanish learned in tenth grade
How did Hermann Ebbinghaus test speed of relearning?
Ebbinghaus
randomly selected a sample of syllables, practiced them, and tested himself on his ability to accurately recall the items
After learning, able to recall some syllables- not forgotten
What were Hermann Ebbinghaus’ findings
the MORE times he practiced a list of
nonsense syllables on Day 1, the LESS time he required to relearn
it on Day 2
SPEED of relearning is one measure of memory retention
How do psychologists describe the human memory system?
INFORMATION-PROCESSING model which likens human memory to COMPUTER operations
Encode
put in new information
Store
organize information
Retrieve
pull out information
What is parallel processing?
considering MANY aspects of a problem
SIMULTANEOUSLY ; brain’s NATURAL
mode of information processing
What did early models of memory formation look like?
Atkinson & Shiffrin- THREE STAGE model of memory
Sensory memory
IMMEDIATE, very brief recording of sensory information in the memory system.
