Encoding:
refers to making mental representations of information so that it can be placed into our memories
-
Memory
- ability to retain information over time through three processes: encoding, storing, and retrieving
- Encoding
- refers to making mental representations of information so that it can be placed into our memories
-
Storing
- is the process of placing encoded information into relatively permanent mental storage for later recall
- - helps to store or encode information in long-term memory.
-
Retrieving
process of getting or recalling information that has been placed into short-term or long-term storage
-
What are the memory processes
- - sensory memory
- - if you do not pay attention the information is forgotten
- - if you pay attention, information is automatically transfered into short-term memory
- - short term memory
- - if you do not pay attention and study material, it is not encoded and it is forgotten.
- - long- term memory:
- - encoded information will remain on a relatively permanent basis.
-
Sensory Memory
refers to an initial process that recieves and holds enviromental information in its raw form for a brief period of time, from an instant to several seconds
-
Short-term memory
also know as working-memory, refers to another process that can hold only a limited amount of information, an average of seven items -2 to 30 seconds.
- two features:
- - limited duration
- -maintenance rehearsal
- - this refers to the practice of intentionally repeating or rehearsing information so that it remains longer in short-term momory.
-
Long-term memory
refers to the process of storing almost unlimited amounts of information over long periods of time.
-
Funtions of short-term memory
- Attending
selectively attend to information that is relevant and disregard everything else.
-
Rehearsing
allows you to hold information for a short period of time until you decide what to do with it.
-
Two features of short term memory:
1. Limited capacity
- when there is limited capacity ther is a interference which means?
it happens when new information enters short-term memory and overwrites or pushes out information that is already there.
-
2. Chunking refers to?
combining separate items of information into a larger unit, or chunk, and then remembering chunks of information rather that individual items.
-
what are the functions of sensory memory?
- - prevents being overwhelmed
- - gives decision time
- - provides stability, playback, and recognition
-
Iconic memory:
is a form of sensory memory that automatically holds visual information for about a quarter of a second or more; as soon as you shift your attention, the information disappears.
-
Echoic memory:
a form of sensory memory that holds auditory information for 1 to 2 seconds
-
•Separate Memory Systems
–primacy effect:
a form of sensory memory that holds auditory information for 1 to 2 seconds
-
•Separate Memory Systems
–recency effect:
•better recall, or improvement in retention, of information presented at the end of a task
-
–primary-recency effect
better recall of information presented at the beginning and end of a task
-
–Declarative memory
•involves memories for facts or events, such as scenes, stories, words, conversations, faces, or daily events
-
–Semantic memory
- type
- of declarative memory and that involves knowledge of facts, concepts, words,
- definitions, and language rules
-
–Semantic
memory
- •type
- of declarative memory and that involves knowledge of facts, concepts, words,
- definitions, and language rules
-
•Declarative versus procedural or nondeclarative
–Episodic memory:
- •type
- of declarative memory that involves knowledge of specific events, personal
- experiences (episodes), or activities, such as naming or describing favorite
- restaurants or hobbies
-
•Declarative versus procedural or nondeclarative
–Proceduralor non declarative memory
involves memories for motor skills (playing tennis), some cognitive behaviors learned through classical conditioning
-
•Two kinds of encoding
–Automatic
encoding
•personal
events
•interesting
facts
•skills
and habits
- •transfer
- of information from short-term into long-term memory without any effort and
- usually without any awareness
-
•Two kinds of encoding
–Effortful encoding
- •involves
- the transfer of information from short-term into long-term memory either by
- working hard to repeat or rehearse the information or, especially, by making
- associations between new and old information
-
•Rehearsing and encoding
–Maintenance rehearsal
refers to simply repeating or rehearsing the information rather than forming any new associations
-
–Elaborative rehearsal
•involvesusing effort to actively make meaningful associations between new informationthat you wish to remember and old or familiar information that is alreadystored in long-term memory
-
•Levels of processing
- –theory
- says that remembering depends on how information is encoded
- –shallow
- processing: poor recall
- –deeper
- and deepest processing: encode by making new association
-
REPRESSED MEMORIES
the process by which the mind pushes a memory of some threatening or traumatic event deep into the unconscious mind
-
eidetic imagery
Form of photographic memory that occurs in children, is the ability to examine a picture or page for 10-3 seconds and then for several minutes hold in one's mind a detailed visual image of the material
-
Unusual Memorie flashbulb memories
vivid recollections, usually in great detail, of dramatic or emotionally charged incidents that are of interest to the personencoded effortlessly and may last for long periods of time
-
Implanting false memories
studies on implanting false memories simply show that a false suggestion can grow into a vivid, detailed, and believable personal memory
-
photographic memory
occurs in adults, is ability to form sharp, detailed visual images after examining a picture or page for a short period of time and to recall the entire image at a later date
