Term
learning (definition)
Definition
any relatively durable change in behavior or knowledge that is due to experience.
Term
associative learning (definition)
Definition
learn associations between events due to conditioning.
Term
classical conditioning
Definition
unconditioned stimulus -> unconditioned response
unconditioned stimulus + conditioned stimulus -> unconditioned response
conditioned stimulus -> conditioned response
Term
acquisition
Definition
initial stage of learning, where associations between stimuli are formed
Term
extinction
Definition
CR occurs less and less when CS is presented many times without UCS
Term
spontaneous recovery
Definition
weakened CR can reappear after some time passes without CS
Term
generalization
Definition
responding similarly to new stimuli similar to CS
Term
discrimination
Definition
organism does NOT respond similarly to new stimuli similar to original conditioned stimulus
Term
operant conditioning
Definition
associate response/behaviors with their consequences
Term
Skinner box
Definition
sound proof with lever, food distributer, light
Term
shaping
Definition
rewards for small steps towards larger goal
Term
discriminative stimulus
Definition
the stimulus that precedes a response becomes signal that the response will result in a reinforcer
Term
reinforcement
Definition
ANY consequence that STRENGTHENS a behavior
Term
positive reinforcement
Definition
the addition (+) of a reward increases frequency of behavior (+)
Term
negative reinforcement
Definition
the removal of something bad (-) increases frequency of behavior (+)
Term
punishment
Definition
any consequence that WEAKENS behavior
Term
positive punishment
Definition
the addition (+) of something bad to decrease the frequency of behavior (-)
Term
negative punishment
Definition
removal of something good (-) to decrease the frequency of behavior (-)
Term
effective punishment (5 things)
Definition
1. add punishment swiftly
2. use punishment just severe enough to be effective
3. make punishment consistent
4. explain the punishment
5. use non-corporeal punishment
Term
biological constraints
Definition
conditioned taste aversion: getting sick after eating. just 1 pairing = conditioned.
Term
observational learning
Definition
learning by watching others
Term
model
Definition
person demonstrating behavior in observational learning
Term
Bandura et. al experiment
Definition
bobo dolls
Term
Atkinson-Shiftrin Model
Definition
3 boxes of memory
Term
sensory memory function
Definition
preserves info in its original sensory form long enough to be selected (or not selected) for further processing
Term
sensory memory capacity
Definition
very large
Term
sensory memory duration
Definition
very brief (1/4 sec)
Term
short term/working memory function
Definition
stores and processes info in consciousness
Term
"working memory"
Definition
storage PLUS active processing
Term
short term/working memory capacity
Definition
limited (7 +/- 2 digits; ~4 chunks)
Term
chunking
Definition
putting together groups of information that are meaningful to you. (ex: words to music, mnemonics)
Term
short term/working memory duration
Definition
relatively brief (10-20 sec w/out rehearsal)
Term
long-term memory function
Definition
hold info over lengthy periods of time (>30 sec)
Term
storage/encoding
Definition
transfer of info from STM-LTM
Term
long-term memory capacity
Definition
unlimited
Term
long-term memory duration
Definition
permanent?
Term
semantic networks
Definition
groups of words that are connected (free association)
Term
deep/semantic encoding
Definition
meaning-based, connecting ideas, prior knowledge
Term
structural encoding
Definition
shallow processing ("does the word have an E in it?")
Term
schema
Definition
group of information already known
Term
self-referent encoding
Definition
make material personally meaningful
Term
organization
Definition
hierarchies, outlines, concept map
Term
generation effect
Definition
create your own study materials
Term
dual-coding theory
Definition
visual/verbal
Term
verbal mnemonics
Definition
acrostics, acronyms, narrative, rhymes
Term
retrieval cues
Definition
hint
Term
transfer appropriate processing
Definition
better memory when encoding and retrieval processes are done in similar environment (room, mood, etc.)
Term
Godden and Baddeley
Definition
context effects in memory experiment - scuba divers
Term
free recall
Definition
ie. essay - few hints/retrieval cues
Term
cued recall
Definition
ie. short answer (several hints/retrieval cues)
Term
recognition
Definition
ie. mult choice (many hints/retrieval cues)
Term
ineffective encoding
Definition
info never got encoded into long term memory
Term
decay
Definition
memories fade over time
Term
interference (definition)
Definition
info displaced by other info
Term
interference (2 types)
Definition
retroactive (forgotten old things), proactive (forgotten new things)
Term
retroactive interference
Definition
forgetting old things because of new things
Term
proactive interference
Definition
forgetting new things because of old things
Term
primacy effect
Definition
remember first words in list really well
Term
recency effect
Definition
remember last words of list really well
Term
repetition/rehearsal
Definition
remember most repeated word in list really well
Term
distinctiveness effect
Definition
different word stands out in list, remembered really well
Term
"false memory effect"
Definition
generalization of schemas to include word that wasn't on list
Term
flashbulb memory
Definition
an emotional, surprising even that feels vid and accurate seared into memory (unreliable)
Term
misinformation effect
Definition
memory for even is altered by misleading post-event info
Term
source-monitoring error
Definition
not remembering where information came from
Term
