Exam 2 (Ch. 5-9 (skipping 6 and 7)) Flashcards
flashbulb memories
-a certain type of memory that is remembered better that others
-ex: JFKs assassination, 9/11
memories are often ___ based on available information
reconstructions
memory reconstructions are made from memories at hand which is why
-the process doesn’t always lead to correct recall
memory is the structures and processes …
involved in both storage and retrieval of information
encoding
the process of how info is initially learned
storage
the process of maintaining info over a short or long period of time
retrieval
the process in recovering information from memory to produce a response
2 types of sensory memory
-iconic memory
-echoic memory
iconic memory
-visual component of sensory memory
-creates and stores visual information
echoic memory
-the auditory component of sensory memory
-creates and stores visual sensory info
memory process
-encoding (mental representations)
-storing (placing into relatively permanent memory)
-retrieving (recalling)
George Sterling memory experiment
-letters flash on screen and subject must remember the letters
-people forget the letters almost immediately
-certain sounds helped to remember what line needed to be focused on
-result: partial reports are better than full reports
short term memory
-a system that actively holds onto a limited amount of info so that it can be manipulated and processed
-often called the contents of consciousness, immediate, or working memory
characteristics of short term memory
-representation (the kind of info a memory system contains)
-duration (how long things can be kept before forgotten)
-capacity (how much info can be held)
traumatic memories often come with…
stories in a lot of detail
capacity
-how much we can hold in the mind at once
-the limit is what we can rehearse in about 2 sec
-limit is usually 7 items
the amount of things we can remember is called
-memory span
technique to condense information is is to
chunk information together
the modal memory model
memorize
3 ways we categorize long term memories
-episodic memory
-sematic memory
-procedural memory
ways we categorize long term memories: episodic memory
-contents pertain to specific events or episodes
-most autobiographical memories (things that happen to us)
ways we categorize long term memories: sematic memory
-contents pertain to specific facts or concepts without personal experience
-definitions and general knowledge
sematic=
meaning
ways we categorize long term memories: procedural memory
-contents pertain to how to do something
-includes most motor and athletic skills
elaborative rehearsal
-the process of manipulating info in immediate memory to connect it to other info already stored in long term memory
elaborative rehearsal chart
memorize
elaborative encoding
-2 levels of processing
-deep processing (encoding new info via connections to existing knowledge)
-shallow processing (encoding new info based on only its surface characteristics)
useful kinds of elaboration
-imagery
-organization
-distinctiveness
-self-reference
2 ways to improve memory
-timing and system design
-use of memories
2 ways to improve memory: timing and system design
-spaced practice is better than practice all at once
2 ways to improve memory: use of memories
-mnemonics give framework for encoding and recall
-memory palace
-acronyms
transfer appropriate processing
-using the same kind of mental processes during testing as encoding to enhance retrieval
errors of omission
-memory errors where info cannot be brought to mind
transcience
-memory of a particular event tends to degrade over time
absent mindedness
-memories are simply unavailable because of a failure to encode in the first place
blocking
not enough distinctive cues available to help recover a specific memory
errors of commission
memory errors where wrong or unwanted info s brought to mind
Hyperthymesia
-rare medical condition that leads to near perfect auto-biographical recall
-amygdala is larger and has more connections to hippocampus
interference theory of forgetting
-memories become irretrievable because they are obscured by other competing info
retroactive interference
new memories go on top of the stack so then the old memories are herder to get to
proactive interference
new memories go on bottom of the stack so then the old memories are easier to get to
2 types of amnesia
retrograde and anterograde
retrograde amnesia
-loss of memory prior to a traumatic event such as a blow to the head or other events
anterograde amnesia
-inability to encode new info into long term memory
-typically permanent and results from extensive damage to the hippocampus
