Chapter 7 and 8 Flashcards
Encoding
involves forming a memory code
Storage
involves maintaining encoded info in memory over time
Retrieval
involves recovering info from memory stores
Attention
involves focusing awareness on a narrowed range of stimuli or events
Shallow processing is what encoding
structural encoding
Shallow processing
emphasizes the physical structure of the stimulus
Intermediate processing is what encoding
phonemic encoding
Intermediate processing
emphasizes what a word sounds like
Deep processing is what encoding
semantic encoding
Deep processing
emphasizes the meaning of verbal input through elaboration
In what order are the types of judgement most effective
Semantic, rhyme/phonemic, visual/structural
Levels of processing theory
proposes that deeper levels of processing result in longer-lasting memory codes
NMDA receptor does what
encourages the flow of info from one neuron to another
NMDA receptors become activated when
the “sending” neuron releases glutamate and the “receiving” neuron excites
LTP is
long-term potentiation which results in enhanced neural processing
Visual imagery
the creation of visual images to represent words to be remembered, if it is easier for concrete objects, it is dual-coding theory
Elaboration
the linking of a stimulus to other info at the time of encoding
Dual-coding theory
holds that memory is enhanced by forming both semantic and visual codes since either can lead to recall
Self-referent encoding
making info personally meaningful
Sensory memory
preserves info in its original sensory form for a brief time, usually a fraction of a second
Atkinson and Shiffrin model of memory storage
sensory input > sensory memory > attention > rehearsal of short-term memory > storage > long-term memory > retrieval back to short-term memory
STM
limited-capacity store that can maintain unrehearsed info for up to about 20 seconds
Rehearsal
process of repetitively verbalizing or thinking about info
Echoic memory
holding auditory info for 1-2 seconds
Iconic memory
holding visual memory for 1 second
Chunk
group of familiar stimuli stored as a single unit
Working memory
modular system for temporary storage and manipulation of info
WMC
working memory capacity referring to one’s ability to hold and manipulate info in conscious attention
LTM
long-term memory is an unlimited capacity that can hold info over lengthy periods of time
Sperling’s sensory memory experiment in 1960
participants stared at a screen and rows of letters were flashed for 1/20th of a second and they were asked to repeat as many letters as possible, but when accompanied by a tone, they can remember more
Retrograde amnesia
no memories backward of injury (usually just of the event)
Anterograde amnesia
no memory forward after injury
Sensory memory is
a copy of input, has limited capacity and stores info for 1/4 second
STM is
largely phonemic, has a small capacity, and stores info for up to 20 seconds
LTM is
largely semantic, has no known capacity limit, ranges from minutes to years
Sensory inputs cause
sensory memory (unattended info is lost) > STM through attention (unrehearsed info is lost) > LTM through encoding (some info is lost over time through retrieval
Flashbulb memories
thought to be unusually vivid and detailed recollections of momentous events
Order of report/recall in STM tests
starts with items most recent, then reports the first items through primacy, then in the middle
