chapter 8 memory psych 101
what are the recommended memory strategies?
-study repeatedly to boost long-term recall - scheduled spaced (not crammed) study times -spend more time rehearsing or actively thinking about the material - make the material personally meaningful, with well-organized and vivid associations - refresh your memory by returning to contexts and moods to activate retrieval cues - use mnemonic devices - plans for a complete nights sleep - test yourself repeatedly- retrieval practice is a proven retention strategy
flashbulb memory
a clear memory of an emotionally significant moment or event
recall
a measure of memory in which the person must retrieve information learned earlier, as on a fill-in-the-blank-test question tests your recall
recognition
a measure of memory in which the person need only identify previously learned, as on a multiple-choice test tests your recognition
relearning
a measure of memory that assesses the amount of time saved when learning material again (studying for a test)
echoic memory
a momentary sensory memory of auditory stimuli; if attention is elsewhere, sounds and words can still be recalled within 3-4 seconds
iconic memory
a momentary sensory memory of visual stimuli; a photographic or picture-image memory lasting no more than a few tenths of a second
hippocampus
a neural center located in the limbic system; helps process explicit memories for storage
working memory
a newer understanding of short-term memory that focuses on conscious, active processing of incoming auditory and visual-spatial information, and of information retrieved from long-term memory
short-term memory
activated memory that holds a few items briefly, such as seven digits of a phone number while dialing, before the information is stored or forgotten (info gets processed in here unable to encode it through rehearsal)
which strategies are better for long term retention?
although cramming may lead to short-term gains in knowledge, distributed practice and repeated self-testing will result in the greatest long-term retention
anterograde amnesia
an inability to form new memories
retrograde amnesia
an inability to retrieve information from ones past
long-term potential (LTP)
an increase in a cell's firing potential after brief, rapid stimulation. believed to be a neural basis for learning and memory
source amnesia
attributing to the wrong source an event we have experienced, heard, read about, or imagined. (also called source misattribution). source amnesia, along with the misinformation effect, is at the heart of many false memories
testing effect
enhanced memory after retrieving, rather than simply rereading, information. also sometimes referred to as a retrieval practice effect or test-enhanced learning
frontal lobes and hippocampus
explicit memory formation
cerebellum and basal ganglia
implicit memory formation
repression
in psychoanalytic theory, the basic defense mechanism that banishes from consciousness anxiety-arousing thoughts, feelings, and memories
misinformation effect
incorporating misleading information into one'e memory of an event
if you try to make the material you are learning personally meaningful, are you processing at a shallow or deep level? which level leads to a greater retention?
making material personally meaningful involves processing at a deep level, because you are processing semantically- based on the meaning of the words. deep processing leads to greater retention
chunking
organizing items into familiar, manageable units; often occurs automatically
your friend has experienced brain damage in an accident. he can remember how to tie his shoes but has a hard time remembering anything told him during a conversation. whats going on here?
our explicit memories (facts and episodes) differ from our implicit memories of skills and procedures. our implicit memories are processed by more ancient brain areas, which apparently escaped damage during the accident
serial position effect
our tendency to recall best the last (a recency effect) and first items (a primacy effect) in a list
what is priming?
priming is the activation (often without our awareness) of associations
what- given the commonality of source amnesia- might life be like if we remembered all our walking experiences and all our dreams?
real experiences would be confused with those we dreamed. when meeting someone, we might therefore be unsure whether we were reacting to something they previously did or to something we dreamed they did
fill-in-the-blank questions test our
recall
implicit memory
retention independent of conscious recollection (also called non declarative memory)
which three memory stages would iconic and echoic occur?
sensory memory
long-term memory
the relatively permanent and limitless storehouse of the memory system. includes knowledge, skills and experiences (information later moves here for later retrieval)
storage
the retention of encoded information over time (retain that information)
spacing effect
the tendency for distributed study or practice to yield better long-term retention than is achieved through massed study or practice
mood-congruent memory
the tendency to recall experiences that are consistent with ones current good or bad mood
automatic processing
unconscious encoding of incidental information, such as space, time, and frequency, and well-learned information, such as word meaning (happens without awareness and produces implicit memories)
what two new concepts update the classic Atkinson-Shiffrin three-stage information-processing model?
(1) we form some memories through automatic processing without awareness. this model only focused on conscious memories. (2) the newer concept of a working memory emphasizes the active processing that we now know takes place in the short-term memory stage
what are two basic functions of working memory?
(1)active processing of incoming visual and auditory information and (2) focusing our spotlight of attention
what are three ways we forget, and how does each of these happen?
(1)encoding failure: unattended information never entered our memory system. (2) storage decay: information fades from our memory (3) retrieval failure: we cannot access stored information accurately, sometimes due to interference or motivated forgetting
what is the difference between automatic and effortful processing, and what are some examples of each?
automatic processing occurs unconsciously (automatically) for such things as the sequence and frequency of a days events, and reading and comprehending words in our own language. effortful processing requires attention and awareness happens, for example, when we work hard to learn new material in class, or new lines for a play
amygdala
emotion-related memory formation
shallow processing
encoding on a basic level based on the structure or appearance of words
deep processing
encoding semantically, based on the meaning of the words; tends to yield the best retention
effortful processing
encoding that requires attention and conscious effort
if you want to be sure what you're learning for an upcoming test, would it be better to recall or recognition to check your memory? why?
it would be better to test your memory with recall (such as short answer or fill in the blank tests questions) rather than recognition (such as multiple choice question tests). recalling information is harder than recognizing it, so if you can recall it that means your retention of the material is better than if you could only recognize it, and your chances of test success are therefore greater
this neural basis for learning and memory, found at the synapses in memory-circuit connections, results from brief, rapid stimulation. it is called...
long-term potentiation (LTP)
mnemonics
memory aids, especially those techniques that use vivid imagery and organizational devices
explicit memory
memory of facts and experiences that one can consciously know and "declare" (also called declarative memory)
multiple-choice questions test our
recognition
deja vu
that eerie sense that "I've experienced this before" cues from the current situation may subconsciously trigger retrieval of an earlier experience
priming
the activation, often unconsciously, of particular associations in memory
which brain area responds to stress hormones by helping to create stronger memories?
the amygdala
retroactive interference
the disruptive effect of new learning on the recall of old information
proactive interference
the disruptive effect of prior learning on the recall of new information
which parts of the brain are important for implicit memory processing, and which parts play a key role in explicit memory processing?
the frontal lobes and hippocampus are important for explicit memory formation and the cerebellum and basal ganglia are key to implicit memory processing
sensory memory
the immediate, very brief recording of sensory information in the memory system (first record this to-be-remembered information)
memory
the persistence of learning over time through the storage and retrieval of information
retrieval
the process of getting information out of memory storage (later get the information back out)
encoding
the processing of information into the memory system- for example, by extracting meaning (get information into our brain)
