Chapter 7: Human Memory Flashcards
What the 3 types memory systems?
- encoding 2. storage 3. retrieval
What is the system of getting information into the memory?
Encoding - forming a memory code.
How does attention in memory work?
involves focusing awareness on a narrowed range of stimuli or events
What is the models of selective attention?
stimulus—·> sensory detection—>recognition of meaning—>response selection—>response
What is the levels-of-processing theory?
proposes that deeper levels of processing result in longer lasting memory codes.
What are three deeper levels of processing encoding?
- structural
- phonemic
- samantic
What is structural encoding?
shallow processing that relates to physical structure of stimulus.
example is the word written in Capital letters?
What is phonemic encoding?
intermittent - relates to what words sound like, involves naming or saying of words.
Example does the word rhyme with weight?
What is semantic encoding?
meaning to it - relates the meaning of verbal input; it involves thinking bout the objects and actions.
Example is would the word fit in the sentence ‘he met a ____ on the street’?
What is elaboration in encoding mean?
a linking in stimulus to other information at the time of encoding.
Example is phobias are often caused by classical conditioning, and you apply that idea to your own fear by doing that you are engaging in elaboration.
What is visual imagery?
the creation of visual images to represent the words to be remembered.
What is dual-coding theory?
holds that memory is enhanced by forming semantic and visual codes, since either can lead to recall.
What did Allan Paivio (1969-2007) point out in visual imagery?
that it is easier to form images of concrete objects than of abstract concepts.
What is self-referent encoding?
It involves deciding how or whether information is personally relevant. (to the person taking in the information)
What is the Atkinson and Shiffrin model of memory storage?
Sensory input—>Sensory memory—>Attention—>Short-term memory—>Storage—>Long-term memory
What is the sensory memory?
preserves information in its original sensory form for a brief time, usually only a fraction of a second.
in the case of vision people really perceive an afterimage rather than the actual stimulus.
What is short-term memory (STM)?
a limited-capacity store that can maintain unrehearsed information for up to about 20 seconds.
What does rehearsal mean?
the process of repetitively verbalizing or think about the information.
What did theorists originally believe about STM?
that the loss of info from STM was due purely to time-related decay of memory traces, but follow up research showed that interference from competing material also contributes to it.
What is a chunk?
is a group of familiar stimuli stored as a single unit.
What is working memory?
a limited capacity storage system that temporarily maintains and stores info by providing an interface between perception, memory and action.(Alan Baddeley 1986-2003)
What is the first component in working memory?
the phonological loop that represented all of STM in earlier models.
What is the second component in working memory?
is a visuospatial sketchpad that permits people to temporarily hold and manipulate visual images.
What is the third component in working memory?
A central executive system that controls the deployment of attention, switching the focus of attention and dividing attention as needed.
also coordinates the actions of the other modules.
What is the fourth component in working memory?
is the episodic buffer, a temporary limited capacity store that allows the various components of working memory to integrate between information and that serves as an interfere between working memory and long-term memory.
What is working memory capacity?
refers to ones ability to hold and manipulate information in conscious attention.
What is long term memory?
is an unlimited capacity store that can hold information over lengthy periods of time.
one P.O.V is that all info stored in LTM is stored there permanently
What is flashbulb memory?
thought to be unusually vivid and detailed recollections of momentous events, provide striking examples of seemingly permanent storage.
