Lec. 15 (memory encoding) Flashcards
the study of behaviorism could explain some forms of learning, but simple _______ could not explain complex activities (like language development)
conditioning
view the mind as an INFORMATION PROCESSOR
cognitive psychologists
seq. process of Information Processing Model for memory (3 steps):
encoding –> storage –> retrieval
step of information processing model: stimuli is transformed into a MENTAL REPRESENTATION; stimuli is represented as a memory code (or type of information)
encoding
types of memory codes (3):
- visual
- acoustic
- semantic
type of memory code: what it MEANS
semantic
encoding is a similar concept to _________ (one kind of info is transformed into another)
transduction
step of information processing model: information maintained in memory
storage
type of long-term memory (3):
- episodic
- procedural
- semantic
information in memory stored in different ways can determine how well it will be ________
remembered
type of LTM: events
episodic
type of LTM: how to do stuff
procedural
type of LTM: what stuff means
semantic
step of information processing model: recovering information from memory; actually remembering something
retrieval
ease of retrieval depends on what 2 things?
- how info was originally encoded + stored
T/F: recall and recognition are the same thing
false
recall or recognition: essay exam
recall
recall or recognition: multiple choice test
recognition
types of Memory (3):
1) sensory memory
2) short term memory (working memory))
3) long term memory
short term memory is also called what?
working memory
information processing model involving the types of memory:
1) external events
2) sensory memory
—- attention
3) short term memory
—- encoding
4) long term memory
according to the information processing model, if you fail to ENCODE after short term memory, you will ________ and the info. will not end up where?
forget; LTM
type of memory: major function is to hold info. long enough to be processed further (sensory registers); helps us to experience a constant flow of information, even if that flow is interrupted
sensory memory
sensory has a very _____ capacity and a very _____ duration
high cap; low duration
mental resources are focused on only part of the stimuli around us; remaining sensory memories fade quickly
selective attention
T/F: sensory memory has a very high capacity (can register everything you hear or see) but a very short lifespan
true
the information in sensory memory decays in ______________
less than one second
type of memory: stores limited amounts of information for a limited time
short term memory (STM)
STM hold info. for up to __________ unless rehearsed
18 seconds
allows us to mentally work with, or manipulate, information being held in STM; also called this
working memory
combining smaller units of information into larger units; strategy you can use to improve your STM
chunking
________ are another way of chunking information to remember it
acronyms
the ______ info. is in STM, the more likely it will be placed in LTM
longer
effortful learning usually requires _________ or _________
rehearsal or conscious repitition
studied rehearsal by using NONSENSE syllables
Ebbinghaus
words that look like words but aren’t; single-syllable nonsense
nonsense syllables
T/F: the more time the nonsense syllables were practiced on Day 1, the fewer repetitions were required to remember on Day 2.
true
type of memory: a relatively LONG-LASTING stage of memory whose capacity to store new information is believed to be UNLIMITED; a relatively deep processing is necessary
long term memory
what kind of deep processing is necessary for information to be put into LTM?
semantic (meaning) coding
quick rehearsal is good for LTM
false (needs to be ELABORATE rehearsal if anything)
information encoded into your memory (LTM specifically) causes _________ changes all over your _________
synaptic; cortex
T/F: your memory of info. is specific to certain portions of your brain
false (all over your cortex)
2 types of LTM:
1) explicit (declarative)
2) implicit (procedural)
type of LTM: with conscious recall; your “what” memories
explicit (declarative
type of LTM: without conscious recall; your “how” memories
implicit (procedural)
explicit LTM are _______ and implicit are ______
declarative; procedural
explicit LTM are processed where?
hippocampus
implicit LTM are processed wehre?
in part, by cerebellum
what kind of information is included in EXPLICIT memories (2)?
- facts (general knowledge)
- personally experienced events
what kind of information is included in IMPLICIT memories (2)?
- skills (motor + cognitive)
- classical and operant conditioning effects
explicit or implicit: state capitals
explicit
explicit or implicit: details about your 6th birthday
explicit
explicit or implicit: tying your shoes or swinging a golf club
implicit
encoding to LTM can either be _______ or _______
automatic or effortful
automatic OR effortful processing to LTM: route to school
automatic
automatic OR effortful processing to LTM: friend’s new cell phone number
effortful
new or unusual information requires _______ and ________ to go to your LTM
attention + effort
the BULK of information requires ________ processing to go to LTM
effortful
T/F: we process an enormous amount of info effortlessly (automatically, without attention)
true!
types of AUTOMATIC processing to LTM (3):
1) space/location
2) time
3) frequency
type of automatic processing: while reading a textbook, you automatically encode the place of a picture on a page
space/location
type of automatic processing: we unintentionally note the events that take place in a day
time
type of automatic processing: you effortlessly keep track of things that happen to you
frequency (ex: eye swelling every sinus infection)
processing that leads to DURABLE and ACCESSIBLE memories; committing new information to memory requires effort
effortful processing
encoding during effortful processing can occur at a _______ or ______ level
DEEP or SHALLOW
levels of processing for EFFORTFUL PROCESSING (3):
- semantic
- acoustic
- visual
level of processing for effortful processing: DEEPEST form of encoding; virtually guaranteed it will go into LTM
semantic
level of processing for effortful processing: how it sounds
acoustic
level of processing for effortful processing: how it looks
visual
acoustic and visual levels of processing are more so _______ methods and are more ________ than semantic
rehearsal; shallow
the more ______ + ______ put into encoding, the better it’s remembered
time + effort
