Learning and Memory Flashcards
a decrease in response to a stimulus caused by repeated exposure
habituation
recovery of a response to a stimulus after habituation has occurred, often caused by introduction of a second stimulus
dishabituation
a way of pairing together stimuli and responses, or behaviors and consequences
associative learning
when an unconditioned stimulus (that produces an instinctive, unconditioned response) is paired with a neutral stimulus; with repetition neutral stimulus becomes conditioned stimulus that produces conditioned response
classical conditioning
loss of conditioned response
extinction
stimulus similar to conditioned stimulus can also produce conditioned response
generalization
when behavior is changed through the use of consequences; changes in behavior due to past outcomes
operant conditioning
increases the likelihood of a behavior
reinforcement
adding a positive consequence or incentive after desired behavior
positive reinforcer
removing something unpleasant after desired behavior
negative reinforcer
animal displays desired behavior to escape unpleasant stimulus
escape learning
animal displays desired behavior in anticipation of unpleasant stimulus
avoidance learning
decreases the likelihood of a behavior
punishment
adds unpleasant consequence in response to behavior to reduce that behavior
positive punishment
removal of a stimulus in order to cause reduction of a behavior
negative punishment
can determine rates behaviors are acquired, two key factors: fixed vs variable and ratio vs interval
reinforcement schedule
reinforces a behavior after a specific number of performances of that behavior
fixed-ratio (FR) schedule (2nd most effective)
reinforces behavior after a varying number of performances of that behavior
variable-ratio (VR) schedule (1st most effective)
reinforces first instance of behavior after a specified time period has elapsed
fixed-interval (FI) schedule (4th most effective)
reinforces a behavior the first time it is performed after a varying interval of time
variable-interval (VI) schedule (3rd most effective)
acquisition of behavior by watching others
observational learning (modeling)
process of putting new information into memory
encoding
information gained without any effort, passive
automatic processing
when we must actively work to gain information
controlled (effortful) processing
putting information into meaningful context, strongest method of encoding (visual is weakest)
semantic encoding
associating each item on list with route through building already memorized
method of loci
associates numbers with items as base, then new list items are paired with previously memorized base items
peg-word system
first and most fleeting kind of memory storage, preserves information in original sensory form, generally lasts less than a second
sensory memory
second longest lasting kind of memory; fades quickly, lasts about 30 seconds without rehearsal
short-term memory
short-term memory store
lies between 5 and 9 items; George Miller called it the “Magical Number 7 + 2”
sensory and short-term memory are based on _______
neurotransmitter activity
holds all of the information that a person is using at a certain time; is a combination of sensory, short term, and long term memories that the person is actively manipulating to achieve a task
working memory
longest lasting kind of memory; requires elaborative rehearsal and is the result of increased neuronal activity
long-term memory
memory that stores facts and stories
explicit (declarative) memory
memory that stores skills and conditioning effects
implicit (nondeclarative) memory
process of demonstrating that something learned has been retained, related to recall
retrieval
retrieval and statement of previously learned information
recall
process of merely identifying piece of previously learned information
recognition
interconnected network the brain organizes ideas into
semantic network
can occur though disorders (such as Alzheimer’s disease, Korsakoff’s syndrome, or agnosia), decay, or interference
memory loss
neural connections form rapidly in response to stimuli as the brain develops, decreases as we age
neuroplasticity
strengthening of neural connections through repeated use, responsible for conversion of short-term to long-term memory
long-term potentiation
the idea that a familiar stimulus takes longer to aquire meaning than an unfamiliar stimulus
latent inhibition
occurs when the details of an event are correctly remembered, but the origin or context of the information (the “source”) is incorrectly attributed
source monitoring error
a pattern of thought or behavior that organizes categories of information and the relationships among them
