  • Front
  • Back
Photographic (eidetic) memory
Being able to recall every detail
False recall
Looking back you recall differently than what really happened
Flashbulb memory
A unique and highly emotional moment may give rise to a clear, strong, and persistent memory
Hierarchies
When you break concepts down
Sensory register
Information over a split second; fleeting images
Iconic memory
What you see; if something is flashed up it stays in your memory for about a second unless you rehearse it
Echoic memory
Stays in for about 3 to 4 seconds unless you rehearse it
Short term memory/working memory
Stays in your mind for about 20 seconds and typically can remember 5-9 items
Serial position effect
We tend to remember the first and last parts of lists the best
Primacy effect
Remember the first part the best
Recency effect
Remember the last part the best
Chunking
The capacity of the working memory can be increased by combining information
F-B-I-T-W-A-C-I-A-I-B-M can be better remembered as FBI TWA CIA and IBM
Long term memory
Unlimited capacity storage; estimates on capacity range from 1000 billion to 1 million billion bits of information
Declarative or explicit
Knowing what thingsa re
Episodic
Knowing a specific event
Semantic
Factual knowledge; general concepts
Procedural or implicit
Based on skills; knowing how to do something
Automatic process
We process an enormous amount of information effortlessly
Automatic process - space
While reading a textbook, you automatically encode the place of a picture on a page
Automatic process - time
We unintentionally note the events that take place in a day
Automatic process - frequency
You effortlessly keep track of things that happen to you
Effortless processing
Committing novel information to memory requires effort just like learning a concept from a textbook. Such processing leads to durable and accessible memories
Rehearsal
Effortless learning usually requires repetition or unconscious repitition
Maintenance rehearsal
Repeating something over and over to help you remember it
Elaborative rehearsal
Trying to relate it to something familiar somehow to help you remember it
Herman Ebbinghaus - curve of forgetting
Says that when you learn something your immediate recall is pretty good. It drops quickly then levels off into hours and days
Spacing effect
We retain information better when we rehearse over time
Next-in-line effect
When you are so anxious about being next that you cannot remember what the person just before you in line says, but you can recall what other people around you say
Visual encoding
When we try to picture something; worst retention
Imagery
Being able to put a picture to a word to remember it
Rosy retrospection
In our memory, we're more likely to remember good things than bad things
Mnemonic devices
A method of learning, typically verbal, used to aid in memorization or thought recovery
Acronym
KPCOFGS - Kingdom, Phylum, Class, Order, Family, Genus, Species
MVEMJSUNP - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto
Method of loci
Imagining yourself in a place to help remember what to say/do
Peg word approach
Jingle; association
Acoustic encoding
Hearing
Semantic encoding
Encoding the meaning; when you get the meaning of a word you're less likely to forget it; best retention
Karl Lashley
Suggested that even after removing parts of the brain, the animals retain partial memory of the maze; wanted to see if memory was still intact. No matter what part of the brain was cut out, at least partial memory was still there
Kandel and Schwartz
Showed that serotonin release from neurons increases after conditioning
Long-term potentiation (LTP)
Refers to synaptic enhancement after learning. An increase in neurotramsitter release or receptors on the receiving neurons indicates strengthening of synapses
Stress hormones and memory
Heightened emotions (stress-related or otherwise) make for stronger memories. Continued stress may disrupt memory
Amnesia
More likely to have explicit memory loss
Retrograde amnesia
Can't remember events before the trauma
Anterograde amnesia
Can't make new memories after the trauma
Implicit memory (procedural)
Involves learning an action while the individual does not know or declare what she knows
Explicit memory (declarative)
Refers to facts and experiences that one can consciously know and declare
Hippocampus
Memory processed here
Infantile amnesia
Hippocampus not fully developed before age of 3 so you can't remember life as an infant
Retrieval
Refers to getting information out of the memory store
Recall
The person must retrieve information using effort
Recognition
The person must identify an item amongst other choices
Relearning
The individual shows how much time (or effort) is saved when learning material for the second time
Priming
To retrieve a specific memory from the web of associations, you must first activate one of the strands that leads to it
Context-dependent memory
Scuba divers recall more words underwater if they learned the list underwater, while they recall more words on land if they learned that list on land
State-dependent memory
You remember if you are in the same state of mind as when you learned it; if you're studying while happy you'll remember more when you're happy than when you're sad
Deja vu
Cues from the current situation may unconsciously trigger retrieval of an earlier similar experience
Mood congruent
If you're happy and you see somebody look at you then you view it as them liking you, but if you're angry and you see seombody look at you then you might take it as them glaring at you
Forgetting
The inability to retrieve information due to poor encoding, storage, or retrieval
Absent-mindedness
Not paying attention to something so you don't remember it
Transience
Over time you just forget; fades away
Blocking
Tip-of-the-tongue phenomenon
Misattribution
Confusing the source of information; putting words in somebody's mouth; remembering a movie scene as something that really happened
Suggestibility
Leading questions
Bias
You believe that your friend wouldn't have done something that they did
Persistence
Unwanted memories from something that happened like a memory of a sexual assaul
Encoding failure
We cannot remember what we do not encode
Storage decay
Poor durability of stored memories leads to their decay
Interference theory
Learning some new information may disrupt retrieval of other information
Proactive
Old learning interferes with new learning (writing last month or last year's date instead of current time)
Retroactive
New learning interferes with old learning
Repression
A defense mechanism that banishes anxiety-arousing thoughts, feelings, and memories from consciousness
Memory construction
While tapping our memories, we filter or fill in missing pieces of information to make our recall more coherent
Elizabeth Loftus
Showed videos of car accidents then asked how fast the cars were going when they either hit each or or smashed into each other. The ones who were asked with "hit" guessed a lower mph than the ones who were asked with "smashed". A week later she asked if there was broken glass and they said yes even though there was none
Misinformation effect
Eyewitness reconstruct their memories when questioned about the event
Korsakoff's syndrome
Forget things because you drink too much alcohol anda it destroys nerve cells that you won't get back; more likely to experience anterograde amnesia
Source amnesia (or attribution)
Attribute to the wrong source an event you have experienced
