Memory, Cognition, Language & Intelligence Flashcards
Sensory Memory
Function: Receiving many sensory inputs at a time
Capacity: Large
Duration: Brief
Echoic
Auditory memory
Lasts the longest
Iconic
Visual memory
Short Term Memory (working)
Function: Hold info for brief time.
Capacity: Limited (7-9)
Duration: Brief (20-30 sec)
Long Term
Function: Memories
Capacity: Large
Duration: ? possible forever.
Maintenance Rehersal
Mental or verbal repetition of info allows info to remain longer.
Encoding
Short term to Long term
Automatic Processing
Big things, survival
Effortful Processing
Have to put in effort
Shallow Processing
memorization
Deep Processing
Making connections+ applications.
Rehearsal
Saying it out load
Spacing
30 min breaks
Imagery
Visualize info
Mnemonics
Words that represent something else
chunking
Combining info
Serial Position effect
Primary: Remembering what comes 1st.
Regency: Remembering what comes last.
Tip of the Tongue
Know you know but can’t produce the knowledge.
Recall
Retrieving memories no cues (essay)
Cued Recall
retrieving memories with cues (fill in the blank)
Recognition
Identifying correct into from a list. (multiple choice)
Encoding specificity Principle
When conditions of retrieval are similar to conditions of encoding makes retrieval is more likely.
Context Effects
Environment is the same
State dependent
Physical (Internal)
Mood Convergence
Mood/emotions
Priming
Activation, often unconscious, of particular associations in memory.
Semantic Network Model
starts 1 place and end in another.
Conversation begins with tree and ends with elementary school teachers.
Explicit
Effortful
Frontal lobe (working memory)
Hippocampus ( Left- verbal, Right - visual)
1. Associate names with faces
2. Spatial mnemonics
During sleep memories move to Cortex)
Implicit
Automatic
Cerebellum - Classical coditioning
Cortex move to Basal Ganglia - procedural memories
Infantile Amnesia
Why activities learned as a baby last to adulthood even if you don’t remember learning it.
Amygdola
Mood Congruence
Long term potentiation (LTP)
Neural basis for learning and remember associations.
Retrograde Amnesia
Unable to remember past episodic event after a head injury
Anterograde amnesia
Unable to form new memories (hippocampus damaged)
Dementia
Decline in mental function
Alzhemiers
Type of dementia
Destroys neurons targeting “memory” neurons 1st.
Ebbinghaus Forgetting Curve
After 1 day we only remember 20% of what we learned)
Retrieval Failure
In long term but can’t get it out
Encoding failure
Info never made it to long term memory
Motivated Amnesia
Suppress undesired memories
Memory Decay
Use or lose it
Retroactive interference
New memories replace old ones
Proactive Interference
Old memories interfere with making new ones.
Imagination Inflation
Imaging an event in great detail
lead to
Believe it is a memory
When it never really happened.
Schema
Mental representation of an object
What you expect to see so you do
but it is not really there.
Loftus experiement
Eye witness testimonies
- 1 word can change how a person sees and event
Bumped vs. smashed when talking about speed of a car when it crashed.
Eidetic Memory
Photographic
Prospective Memory
Remember something you need to do I the future,
“I need to remember to take the trash out when I get home.”
Metacognition
Thinking about thinking.
“Why did I think about that”
Barnum Effect
Believing vague info is true. (horoscopes)
prototype
A mental image of a category
Divergent Thinking
Proposing many possible solutions in an attempt to suggest i that may work
Convergent thinking
Bringing together different ideas to determine a single best solution
Functional Fixedness
Tendency to view objects as functioning only in their usual way.
Mental set
Tendency to persist in solving problems with tried and true solutions.
Reprehensive Heuristic
Determining the likelihood of an event by comparing it to the prototype for the event.
Availability Heuristic
Determining the likelihood of an event based on how readily we remember instances of the event.
Overconfidence
Confidence > accuracy
Exaggerated fear
Opposite of overconfidence.
Confirmation bias
Focus only on supporting evidence
Belief Perserverance
Clinging to beliefs even if prove false.
Framing
How an issue is worded can influence judgement.
Belief bias
Beliefs distort logic
Hindsight bias
Belief that you could have known an event was coming and changed it.
Phoneme
Sound
Morpheme
Smallest distinctive sound that has meaning.
Babbling stage
1st stage
spontaneous phonemes.
1 word stage
2nd stage (1 year)
Dada, mama, doggy
2 word stage
3rd stage (2 years)
more food, no dada
overgeneralization
Generalize grammar rule so they apply to everything.
Broomed vs. swept.
Skinner
Reinforcemnt leads to language
Chomsky
Born with universal grammar.
Whorfirm Hypothhesis
Language shapes thought patterns.
