memory | retention of information over time |
paradox of memory | our memories are either very good or poor in certain situations |
the paradox of memory hinges on a crucial fact, which is... | the same memory mechanisms that serve us well in most circumstances can cause problems in others |
memory illusion | false but subjectively compelling memory |
how do we reconstruct our memories? | actively |
how are memories shaped? | by hunches, expectations and cultural backgrounds |
span | how much information each system of memory can hold |
duration | over how long a period of time system of memory can hold information |
sensory memory (system of memory) | brief storage of perceptual information before it's passed to short-term memory |
iconic memory | visual sensory memory |
eidetic imagery | photographic memory |
echoic memory | auditory sensory memory |
short-term memory (system of memory) | memory system that retains information for limited durations and is closely linked to working memory |
working memory | ability to hold on to information we're currently thinking about, attending to, or processing actively |
decay | fading of information from memory over time |
interference | loss of information from memory due to additional incoming information |
retroactive interference | interference with retention of old information due to new information |
proactive interference | interference with acquisition of new information due to previous learning of memory |
magic number | span of short-term memory, according to George Miller, is 7+ or -2 pieces of information |
chunking | organising information into meaningful groupings, which allows us to extend the span of the short-term memory |
rehearsal | repeating information to extend the duration of retention in short-term memory |
maintenance rehearsal | repeating stimuli in their original form to retain them in short-term memory |
elaborative rehearsal | linking stimuli to each other in a meaningful way to improve retention of information in short-term memory |
levels of processing | depth of transforming information, which influences how easily we remember it |
long-term memory | relatively enduring (from minutes to years) retention of information stored regarding our facts, experiences, and skills |
what are the differences between short and long-term memory? | capacity and duration are endless in long-term memory while they are limited in short-term memory |
permastore | type of long-term memory that appears to be permanent |
primacy effect | tendency to remember words at the beginning of a list especially well |
recency effect | tendency to remember words at the end of a list especially well |
serial position curve | graph depicting both primacy and recency effects on people's ability to recall items on a list |
what are types of long term-memory? | explicit memory and implicit memory |
explicit memory | memories we recall intentionally and of which we have conscious awareness |
semantic memory | our knowledge of facts about the world |
episodic memory | recollection of events in our lives |
implicit memory | memories we don't deliberately remember or reflect on consciously |
procedural memory | memory for how to do things (motor skills and habits) |
priming | our ability to identify a stimulus more easily or quicker after we've encountered similar stimuli |
what are the three processes of memory | encoding, storage, and retrieval |
encoding | process of getting information into our memory banks |
the role of attention | to encode something, you must attend to it |
next-in-line effect | in a group/line being so preoccupied with what you are going to do, you don't hear or notice what others before you have done |
mnemonic | a learning aid, strategy, or device that enhances recall |
pegword method | rhythm with words, link your concepts to the words of the rhythm |
keyword method | word that relates in phonetics to your word, and breach an association between that word |
storage | process of keeping information in memory |
how do we store our experiences in memory? | it depends on our interpretations and expectations of events |
schema | organised knowledge structure or mental model that we've stored in memory (a script) |
retrieval | reactivation or reconstruction of experiences from our memory stores |
retrieval cues | hints that make it easier for us to recall information |
what are the three ways to assess people's memory? | recall, recognition, and relearning |
recall | generating previously remembered information |
recognition | selecting previously remembered information from an array of options |
relearning | reacquiring knowledge that we'd previously learned but have largely forgotten over time |
distributed practice | studying information in small increments over time |
massed practice | studying in large increments over a brief amount of time |
tip-of-the-tongue phenomenon | experience of knowing that we know something but being unable to access it |
encoding specificity | phenomenon of remembering something better when the conditions under which we retrieve information are similar to the conditions under which we encoded it |
context-dependent learning | superior retrieval of memories when the external context of the original memories matches the retrieval context |
state-dependent learning | superior retrieval of memories when the organism is in the same physiological or psychological state as it was during encoding |
mood-dependent learning | superior retrieval when in the same mood |
engram | the physical trace of each memory in the brain |
Lashley's research | seeing if removing different parts from rats' brains affect memory |
long-term potentiation (LPT) | gradual strengthening of the connections among neurons from repetitive stimulation |
LPT and glutamate | LPT enhances the release of glutamate into the synaptic cleft which results in enhanced learning |
where is memory stored? | most importantly the hippocampus, but there are other parts of the brain that are also crucial for memory |
retrogade amnesia | loss of memories from our past |
anterograde amnesia | inability to encode new memories from our experiences |
the role of amygdala | interacts with the hippocampus during memory formation |
erasing painful memories | adrenaline and noradrenaline help store emotional memories |
around what age does memory decay begin? | around 65 |
what is the most frequent cause of senility | dementia, Alzheimer |
habituation | a decrease in attention to familiar stimuli |
meta-memory | knowledge about our own memory abilities and limitations |
flashbulb memories | emotional memory that is extraordinarily vivid and detailed |
phantom flashbulb memory | the idea that many seeming flashbulb memories are false |
source monitoring confusion | lack of clarity about origin of a memory |
cryptomnesia | failure to recognise that our ideas originated with someone else |
suggestive memory techniques | procedures that encourage patients to recall memories that may or may not have taken place |
misinformation effect | creation of fictitious memories by providing misleading information about an event after it takes place |
weapon focus | people tend to focus on the weapon rather than the perpetrator's appearance |
