Unit 5: Cognition Flashcards
Effortful processing
encoding that requires attention & conscious effort
Automatic processing
unconscious encoding of incidental info (ex: time, frequency, space, well-learned info ex: word meanings)
Procedural memory
the type of memory that we use to do everyday tasks / memory of physical actions (stored in cerebellum)
knowing how to ride a bike
Well-practiced knowledge
Conditioned associations: smells = place
info abt: space, time, frequency
Recall
process: retrieval of info not currently in your conscious awareness but was learned previously
ex: fill-in-the-blank test
Recognition
a person is able to identify items/something previously learned. recognizing
ex: multiple choice test
Relearning
a measure of memory that assesses the amount of time saved when learning material again
Encoding
Process of getting new info into memory syst (ex: extracting meaning)
process of sensing information, processing info & storing it to be retrieved later
Storage
Process of retaining encoded info over time
Retrieval
Process of getting info out of memory storage
Parallel processing
Processing many aspects of a problem simultaneously
Brain’s natural mode of info processing for many functions
Sensory memory
Immediate very brief recording of sensory info in memory syst
Spacing effect
Tendency for distributed study/practice to yield better long-term retention than is achieved thru massed study/practice
Testing effect/practice effect/test-enhanced learning
Enhanced memory after retrieving, rather than simply rereading info
Deep processing
encoding based on the word’s meaning (semantically), best for retaining info
Shallow processing
encoding on basic level, based on structure/appearance of words
Selective attention
Completely Focused on a specific topic/stimulus; keeping awareness on a specific stimulus among all sensory input / certain info & letting the rest go
Divided attention
Focused on multiple tasks at once makes it harder to focus on 1 task
Attempt to split focus but loses info from both procedures
concentrating on more than one activity at the same time
Problem: is caused by the brain mechanism that allows us to switch between multiple different tasks
Metacognition
Ability to control thoughts / be aware of them
“Thinking abt thinking”
ability to evaluate a cognitive task to determine how best to accomplish it, & then to monitor and adjust one’s performance on that task
Implicit memory (procedural) / Non-declarative
Acquired thru automatic processing, formed w/o awareness
Retaining learned skills/classically conditioned associations but cannot be consciously recollected
info/knowledge that affects behavior or task performance
Long-term memory
Relatively permanent & LIMITLESS memory storehouse of syst
Includes knowledge, skills, experiences
Sensory memory (echoic, iconic)
Immediate, very brief recording of sensory info in memory syst
Echoic: a momentary sensory memory of AUDITORY stimuli, if attention is some where else, sounds/words can still be recalled w/ in 3-4 seconds
Iconic: a momentary sensory memory of VISUAL stimuli; a picture image memory lasts no more than a few 1/10s of a second
Prospective memory
Remembering to do smthn/perform an action in the future/at a certain time
Explicit memory (semantic, episodic) / Declarative
Acquired thru effortful processing, formed thru studying, rehearsing, processing
Episodic: includes memories of personal experienced events
Semantic: includes memories of general knowledge of facts, names, & concepts
Retaining facts & experiences that u can consciously know and “declare” / recollect
Hippocampus
Neural center in limbic syst, helps process explicit (conscious) memories of facts & events for storage
Memory consolidation
Neural storage of a long-term memory
Long-term potentiation (LTP)
An increase in cell’s firing potential after brief rapid stimulation, neural basis for learning & memory
Priming
Activation, often unconsciously of particular associations in memory
Noam Chomsky
LANGUAGE, BIOLOGICAL DETERMINISM believed that humans have an inborn or “native” predisposition to develop lang
Biological determinism
He believes that lang acquisition is innate & that children effortlessly learn the lang of home
Hermann Ebbinghaus
The forgetting curve / spacing effect
found that memory for novel information fades quickly, then levels out
Wolfgang Kohler
Insight / gestalt
showed that humans arent the only creatures to display insight
Chimpanzee experiments
discovered that learning can occur when we gain insight into an entire situation, as opposed to focusing only on an individual part
Elizabeth Loftus
Misinformation/Eyewitness/False Memories
Demonstrated misinfo effect + memory reconsolidation
(that when ppl = exposed to subtle misleading info, ppl may misremember)
studied repressed memories & false memories; showed how easily memories could be changed & falsely created by techniques ( leading questions & illustrating the inaccuracy in eyewitness testimony)
George A. Miller
Proposed that we can store abt 7 pieces of info in short-term memory
Short term memory/chunking influential
Encoding
process of getting info into the memory syst
How do we encode explicit memories / declarative memory?
thru effortful processing
How do we encode implicit / nondeclarative memories?
thru automatic processing
Chunking
organizing items into familiar, manageable units, often occurs automatically
Mnemonics
memory aids, especially techniques that use vivid imagery & organizational devices
Spacing effect:
tendency for distributed study/practice to yield better long-term retention than thru mass study/practice
Testing effect
enhanced memory after retrieving, rather than simply rereading info (aka retrieval practice effect / test enhanced learning)
Shallow processing
encoding on a basic level (word appearance/structure)
Deep processing
encoding semantically (meaning of words/symbols)
Semantic memory
category of long-term memory that includes memories of general knowledge of facts, names, and concepts unrelated to specific experiences
Episodic memory
Memory of a specific event that happened while the subject was present.
Ex: Like a TV episode
Memory consolidation
Neural storage of a long-term memory
Flashbulb memory
a clear sustained memory of a emotionally significant moment/event (9/11)
Hippocampus
Neural center in limbic syst, helps process explicit (conscious) memories of facts & events for storage
Long-term potentiation (LTP)
An increase in cell’s firing potential after brief rapid stimulation, neural basis for learning & memory
Priming
Activation, often unconsciously of particular associations in memory
Encoding Specificity principle
the idea that cues & context specific to particular memory will be most effective in helping u recall it
Mood-congruent memory
tendency to recall memories that are consistent w/ one’s current good/bad mood
Serial position effect
our tendency to recall best the last(recency effect) & first items(primacy effect) on a list
Retrieval cues
When encoding a target piece of info, u associate it w/ other things to better remember (visual cues or senses)
Anterograde amnesia
An inability to form new memories
Retrograde amnesia
An inability to retrieve info from one’s past
