Unit 5: Cognitive Psychology Flashcards
Cognition
The mental processes involved in gaining knowledge and comprehension
+ Thinking
+ Knowing
+ Remembering
+ Judging
+ Problem-solving
Explicit memory
Declarative memory we work to remember
Subtypes:
Semantic (meaning)- Earth is the 3rd rock(planet) from the sun
Episodic- Remembering getting my first dog as a pet
Implicit memory
Non -declarative memory
Subtype:
Procedural- ability to perform certain tasks without conscious awareness
Memory
The persistence of learning over time through the storage and retrieval of information
Measures of explicit memory
+Recall
+Recognition
+Relearning
Memory process
Encode -> Storage -> Retrieval
+ Getting information in
+ Retaining encoded information
+ Get info out of memory
The Attkinson-Shiffrin
Three-stage model of memory includes
a) sensory memory
b) short term memory
c) long-term memory
Sensory Memory
+ Iconic- fleeting photographic visual (1/2 of asec)
+ Echoic- fleeting auditory (3-4 secs)
Properspective Memory
The memory for tasks to be completed in the future
+ Ex. Sending an email, paying a bill, taking a medication
Dependent on short and long term memory
Automatic processing
Unconscious encoding of incidental information such as…
+ Space
+ Time
+ Frequency (how often)
Parallel processing
Ability to deal with multiple stimuli simultaneously
Effortful processing
Encoding that requires attention & conscious effort
+ Spacing effect (over time..)
(aka distributed practice)
+ serial position effect (recall tendency to remember the first and last items in a list better than those in the middle, primacy and recency effects)
Semantic memory
Conscious long-term memory for meaning, understanding, and conceptual facts about the world
Ex. Remembering the meaning of a situation rather than specific details
George Miker
The number of ____ humans can hold in their working memory
+ 7 digits
+ 6 letters
+ 5 words
Hippocampus and frontal lobe
Processes explicit memories for storage
+ sematics (facts)
+ episodics (experienced events)
Cerebellum and basal
Ganglia- implicit memories
+ skills, procedures
+ associations (classical conditioning)
Amygdala
flashbulb memories
involved with the experiencing of emotions.
+ Anger, aggression, fear, and stress are all common emotional triggers.
- Long-term potetiation (LTP)
- Block LTP
- Mimic LTP
- increase in synaptic firing
- limit learning
- increase learning (more rehearse, more you’ll learn)
Context dependent memory
Remembering is dependent upon enviroment
State dependent memory
+ Mood congruent
ex. If bad mood then recall bad events, if good mood then recall good events
Retrograde amnesia
ANterog`+ cannot retrieve past information
+ what people usually think of as amnesia
Anterograde Amnesia
+ cannot form new memories
BUT!
+ Non-verbal tasks- remembers where to find waldo
+ Procedural skills - how to use a new smartphone
Encoding Failure
the information doesn’t get into memory. Encoding failures can occur because of inattention to the target information or interference when the target information is presented.
Retrival failure
Ever had something at the tip of your tongue?
Proactive interference
Prior learning disrupts recall of new info
+ ex. guy confusing gf’s name with his old ex’s
Retroactive interference
New learning disrupts the recall of old learning
How to remember ?
Procative
Old disrupts new
Retroactive
New disrupts old
Motivated forgetting
+ Repression: banish uncomfortable memories
+ Reality- likely uncommon
EMOTIONAL EVENTS POWERFUL
Construction errors
Reconsolidation: retrieved memories are altered
Misinformation effects
Misleading info distorts one’s memory of an event
+ ex. “About how fast were the cars going when they smashed into eachother”
+ “About how fast were the cars going when the accident occured”
Source Amnesia
Faulty memory for when or how the info was learned or imagined
+ex. comedian accidentally stealing a joke
Source monitoring
Keeping track of where you learned something
Internal source monitoring failure
Ex. confusing dreams for reality
source monitoring failure
Inaccurately identifying the source of the info
Concept
categories of ideas, objects, events with common properties
x Helps us organize info in our brains, but concepts also influence our thoughts and behaviors
Protypes
+ Best examples of a category
+ More than just visual:
+ prejudice
+ ex. heart attack symptoms wrongfully identified
