memory and learning Flashcards
(138 cards)
Define memory?
The faculty for recalling past events and past learning.
Name and explain the activities involved in memory?
Encoding—Getting information into memory in the first place
Storage—Retaining memories for future use
Retrieval—Recapturing memories when we need them
name the theories of memory?
Psychologists have developed a number of models of explanation, including the information-processing model and the parallel distributed-processing model, or connectionist model.
explain the information-processing model?
information-processing model view of memory suggesting that information moves among three memory stores during encoding, storage, and retrieval.
what is iconic memory?
visual sensory memory is also called iconic memory, meaning it is like a small copy of the visual event we have just encountered, just as a computer icon is a small visually descriptive representation of the program or file it represents
what is echoic memory?
echoic memory is an auditory system that holds information for a short time.
define the three-stage memory model.
1- Sensory memory: holds sensory information that lasts up to 1/2 sec for visual; 2-4 sec for auditory the capacity is large.
2- working memory: holds information temporarily for analysis up to 30 sec without rehearsal the capacity is limited to 5-9 items
3- long-term memory: relatively permanent storage with relatively unlimited capacity.
explain working memory and short-term memory?
1- multi-store model: a storage location-somewhere that stimuli could be held for a brief period of time. (Atkinson and Shiffrin)
2- working memory: composed of a number of related process with different systems responsible for processing the different kinds of information while consciously working on, keeping it available for immediate access. (Baddeley and Hitch)
explain the 3 system of Baddeley and Hitch’s short-term memory?
1- The central executive is the supervisory system that monitors and coordinates the entire working memory system by allocating attentional resources and selectively prioritizing information as it relates to two subsystems: the phonological/ articulatory loop and the visuospatial sketchpad.
2-The phonological loop processes spoken and written information; it is frequently likened to a “little voice” that continually repeats what needs to be remembered, keeping that information active in memory.
3- The visuospatial sketchpad keeps track of images and spatial locations needed for navigation purposes, and is frequently referred to as the inner eye.
4- In 2000 Baddeley added a third subsystem, the episodic buffer, that serves to link together information from the other parts of working memory and also creates links to time and order as well as to long-term memory.
what is the difference between short-term memory and working memory?
working memory is an entire theoretical framework composed of hierarchical processes used to temporarily store and manipulate information in short-term storage.
So, in many ways, working memory is short-term memory, but is composed of a number of sub-systems, rather than a unitary model as first proposed by Atkinson and Shiffrin
what is needed to maintain attention?
To maintain attention on a specific task, one needs to have a goal.
what is the role of executive attention?
working memory and executive function is controlled by executive attention; responsible for maintenance of goals and controlling interference while a person is engaged in complex cognitive tasks.
what is memory stores?
The three systems of memory proposed by the information-processing model are comparable to the operation of a computer.
Sensory memory, working memory, long-term memory. all three are called memory stores.
what is parallel distributed-processing model?
parallel distributed-processing model (PDP) (or connectionist model), holds that newly-encountered pieces of information immediately join with other, previously-encountered pieces of relevant information to help form and grow networks of information. (Baddeley and Hitch).
what is automatic processing?
automatic processing encoding of information with little conscious awareness or effort
define effortful processing?
effortful processing encoding of information through careful attention and conscious effort.
what is the differences between effortful and automatic processing?
1- the encoding process will be disrupted if the individual attempt to do 2 tasks at the same time in effortful processing but the same doesn’t stand true for automatic processing.
2- extra effort doesn’t make the automatic processing more efficient while it does the effortful processing.
what is sensory memory?
sensory memory: memory involving a detailed, brief sensory image or sound retained for a brief period of time.
what is the significand’s of George Sperling’s research?
Test of sensory memory In his study of the duration of sensory memory, George Sperling flashed a chart of letters, similar to this one, for 1/20 of a second. He found that participants could recall almost all the letters in a particular row if asked to do so immediately, but half a second later, their performance declined.
define the working memory?
working memory a short-term memory store that can hold five to nine items at once.
how to make sure the information is encoded into working memory?
rehearsal conscious repetition of information in an attempt to make sure the information is encoded.
define long-term memory?
long-term memory the memory system in which we hold all of the information we have previously gathered, available for retrieval and use in a new situation or task.
what is spaced practice effect?
spaced practice effect facilitated encoding of material through rehearsal situations spread out over time.
define eidetic memories?
producing visual images with extraordinary detail and near-perfect accuracy. Although recalling an object or scene that they have just witnessed, these people behave as if they are recalling items while looking at a photograph. Thus their detailed images are called eidetic memories, or photographic memories.
