  1. Memory
    • an indication that learning has persisted over time
    • ability to retrieve and store information
    • starts as an impulse
    • Synapses send information to other neurons
  2. Encoding
    • Part of memory
    • when you get information into your brain it happens through all other senses
  3. Storage
    • Part of Memory 
    • retaining information
  4. Retrieval
    • Part of Memory 
    • the ability to pull information out of storage and into your consciousness
  5. 3 Stage Model of Memory
    • Stage 1:Sensory Memory-sensory memory of something you've just experienced
    • Stage 2:Short Term Memory-can hold a lot of information, usually pertinent to what you are immediately doing
    • Stage 3:Long Term Memory-Memories that have been stored, these can fade but exist in an unlimited amount
  6. How does encoding happen?
    • Automatic Processing-requires no effort, hard to turn of, happens all the time
    • i.e. looking at what someone is wearing even though you're listening to what they're saying
    • Effortful Processing-requires effort and the conscious choice to focus on a particular thing
  7. Effortful Processing
    • type of encoding that requires effort and conscious choice to focus on a particular thing
    • Happens in 3 ways:
    • Rehearsal- memory formed over rehearsing something over and over again  
    • Spacing Effect- rehearsing in an organized, well spaced, manner over time 
    • Serial Position Effect- the position something holds in a series has an effect on how well we remember it; easier to remember something at the beginning and the end of a sequence
  8. How do we encode?
    • We encode with meaning; we link it to something we know, building it off of previous information, or relating it to a previous piece of information 
    • Through Visual or Mental Organization
    • Mnemonic-memory aids
    • Chunking-acronyms or grouping of information in order to remember it 
    • Hierarchies- similar to an outline, big topics that include smaller topics in order to rank information
  9. Iconic
    • Sensory Memory 
    • brief, fleeting, photographic memory
  10. Echoic
    • Sensory Memory 
    • brief ability to obtain what you just heard
  11. Short Term Memory
    • limit in space and duration 
    • some say it's limited to 7 pieces of information
    • also called your working memory
  12. Long Term Memory
    believed that memory is unlimited
  13. Why do we forget memories?
    • because new memories override old ones
    • memory trace decays, if memories aren't used or recalled the memory fades overtime?
  14. Where are memories stored?
    Memories are stored everywhere, not in one single space
  15. Effect of Stress on Memory
    can either make memories more vivid or repressed
  16. Amnesia
    loss of memory
  17. Implicit Memory
    • Also known as Procedural Memory
    • You know how to do something
    • i.e. tie your shoes, brush your hair
  18. Explicit Memory
    • Also known as declarative memory 
    • You remember something specifically something you have experienced
    • i.e. what you did over spring break
  19. Hippocampus
    • a neural center in the limbic system
    • helps process explicit memories for storage
    • damage to the left side is verbal information loss
    • damage to the right side is loss of visual designs and location
  20. Retrieval
    • the ability to recall information that is not in our conscious awareness
    • We retrieve it through cues: visual, words, experiences
  21. Deja Vu
    • means "already seen" in French
    • a situation's detail reminds you of a past situation that is highly similiar
  22. State Dependent Memory
    when you learn something in one state it's easier to remember in the same state again
  23. Forgetting
    • -Encoding: the information was never fully encoded into your brain        
    • -Storage: memory trace decays, or fading of the memory as it is stored
    • Retrieval: you can’t quite recall a memory (Ex: when something is “on the tip of your   tongue”)
    • -Memories can also become too distorted or too persistent
  24. Schacters 7 Sins of Forgetting
    • Absent Minded-inattention to detail
    • Transience-something is blocking the memory, storage decay over time 
    • Blocking-can't quite remember it 
    • Misattribution-our memories become distorted and we're confusing the source of information
    • Intrusion-persistent unwanted memories 
    • Bias-colors recollections and causes your to misremember
    • Suggestability-memories become distorted because of suggestions being made in how we are being asked or how other recall the event
  25. Cognition
    all mental activities associated with processing  , understanding and communicating
  26. Concept
    a mental grouping of of similar objects group and people
  27. Prototype
    • a mental image that we create that incorporates all the features that we associate with a concept 
    • our "ideal"
  28. How do we solve problems?
    • Algorithms-step by step procedure that guarantees a solution, goes through all the possible answers until you find the right one, takes more time
    • Heuristics-a rule of thumb strategy, look at all the probable answer and find the highest probability of the right answer, more prone to error but takes less time
    • Insight-a sudden flash of inspiration
  29. Obstacles to problem solving
    • Confirmation Bias-search for information that confirms our beliefs , biased
    • Fixation- the inability to see a problem from a fresh perspective, stress and tension adds to this 
    • Function Fixedness- when we perceive a function of an object as fixed and unchanging
  30. Overconfidence
    tendency to believe more than we actually know
  31. Framing
    looking at something else from a certain perspective
  32. Belief Perseverance
    our inclination to hold onto beliefs despite evidence that contradicts them
  33. Language
    • our written, spoken and gestured words and the way we combine them

    • One word sentence at 1 year
    • Two word sentence at 2 years
  34. Language Development Theories
    • Skinner- we talk because of association, imitation and reinforcement
