Sensory memory- ionic
Visual
Sensory memory- echoic
Auditory
Digit span
Capacity of short term memory (7 +/- 2 items)
Short term memory
Chunking
Long term memory
Encoding, storage, and retrieval
Encoding: process used to store information in memory
Storage: process used to maintain information in memory
Retrieval: process used to get information back out of memory
Recall vs. recognition tasks
Recall: you have to generate an answer
Recognition: you don’t need to generate an answer
Free recall
“Recall all the words you can from the list you just saw”
Serial recall
“Recall the names of all previous presidents in the order they were elected” (need to recall order as well as items)
Cued recall
Give participants some clue to trigger recall
Implicit vs. explicit memory tasks
Explicit: involves conscious recollection (participant knows they are trying to retrieve information from their memory)
Implicit
Bahrick’s rules of very long term memory (permastore)
Levels of processing theory (deep vs. shallow processing)
Deep: encoding information based on meaning or associations with other knowledge
Shallow: encoding based on sensory characteristics (appearance or sound)
Morris study
Two processing tasks: semantic vs. rhyme
Semantic: “the (train/apple) had a silver engine”- standard recognition test
Rhyming: “(eagle/chair) rhymes with legal”- rhyme recognition test
*Memory performance also depends on the match between encoding processes and type of test
Serial position effect
Tendency to remember the first and last names in a series better than those in the middle
Primary vs. recency effects
Primary: we tend to remember the first items in a series better
Recency effect: we tend to remember the last names in a series better
Working memory
The system(s) involved in the TEMPORARY storage of information for cognitive skills (reading, comprehension, learning)
Brooks interference study
One group saw block diagram of letter, memorized it, asked to mentally travel letter and indicate if the corner was on the extreme top or bottom
Second group saw a sentence, memorized it, and were asked to classify each word as a noun verbally
Mnemonist
Using patterns, ideas, or associations to assist in remembering something (All Cows Eat Grass)
Sensory synthesia
People have unusual, and usually involuntary associations between different sensory experiences
Different types of synesthesia depending on the combination of senses/representation
Days, numbers, and months of the year evoke different personalities
Letters or numbers are perceived as inherently colored
Penny example: failures of memory
We cannot remember what we fail to encode
Ebbinghaus forgetting curve
more recent you learn something, the more retention/recall ability; less recent, less retention/recall ability
Savings Method (Relearning)
Way of measuring retention by measuring how much faster one relearns material that has been previously relearned and forgotten
