The ability to store and retrieve information over time
Memory
the porcess by which we transfor what we perceive. think, or feel in to an enduring moemory
Encoding
the process of maintaining information in the memory over time
storage
the process of maintaining information in the memory over time
Retrieval
the precess of storing new info by converting it into mental pictures
Visual Imagery Encoding
The act of catergorizing info by noticing the relationships among an series of items
Organizational encoding
the process of maintaining information in memory over time
Memory storage
a fast-decaying store of auditory information
Echoic Memory
a fast-decaying store of visual information
Iconic Memory
A place where nonsensory information is kept for more than a few seconds but less than a minute
Short-term Memory
The process of keeping information in short-term memory by memtally repeating it
Rehearsal
combining small pieces of information into larger clusters or chunks that are more easitily held in short-term memory
chunking
active maintenance of information in shor-term storage
working memory
a place in which information can be kept for hours, days, weaks, or years
long-term memory
the inability to transfer new information from the short-term store in to the long-term store.
anterograde amnesia
the inablitly to retreive information that was acquired before a particular date, ususally the date of an injury or operation
retrograde amnesia
external information that is associated with stored information and helps bring it to mind
retrieval cue
the idea a retreival cue can serve as an dffextive reminder when it helps re-cut the speccifit was in which information was encodid
state dependnt retrival
a network of associated facts and concepts that make up our general knowledge fo the world
seemantic memory
the collection of past personal experiences that hat occurred at a particular time and place
epiosodie
forgetting what occure with the passage of time
transience
situation in which later learning impairs memory for information acquired earlier
retroactive interference
situatsion in which earlier learningimpaires memory for information acquire later
proactive interference
a lapse in attention that results in memory failure.
absentmidnedness
remembering to do things in the future
prospective memory
a failure to retrieve infor that is available in memory even though you are trying to produce it
Blocking
the distorting influences of present knowledge, beliefs and feeeling on recollection of previous experiences
bias
the instrusive recollection of events that we wish we coould forget
persistence
detailed recollection flashwhan an dhwere we heard about
flash bulb
some experience that results in a relatively permanent change in the state of learner.
learning
a general process in wich repeated or prolonged exposure to a stimulus results in a gradual reduction in responding
habituation
when a neutral stimafter bulus evokes a response after being paired with a stimulus hat natually evokes a response
classical conditioning
somting that reliably produces a natrually occuring reaction in an organism
unconditioned stimulus (US)
a reflexive reaction that is reliably elicited by an unconditioned sumulus
unconditioned response (UR)
a stimulus thatis initially neutral and produces no reliable response in an organism
conditioned stimulus (CS)
a reaction that resembles an unconditioned response but is produced by a condtiioned stimulus
Conditioned (CR)
the phase of classical conditioning when the CS and the US are presented together
Acquistition
ethe gradual elimination of a leared response that occurs when the US is no long presented
extinction
the tendency of a leared behavior to recover from extinction after a rest period
Spontaneous Recovery
the tendency of a leared behavior to recover from extinctino after a rest period
Spontaneous Recovery
a process in which the CR is observed even though the cs is slightly different from the original one used during acquisition
Generalization
a type of learning in which the consequences of an organism's behavior determine whether it will be repeated in the future
operant conditioning
The principle that behaviors that are followed by a "satisfying state of affiars" tend to be repeated and those that produce an "unpleasant state of affairs" are less likely to be repeated
law of effect
behavior that an orfanism produces that has some impact on the environment
operant behavior
any stimulus or event that functions increase the likelihood of the behavior that led to it
reinforcer
any simulus of event that functions to decrease the likelihood of the behavior that lead to it
punisher
learning that results from the reinforcement of sucessive approximations to a final desired behavior
Shaping
an operant conditioning principle in which reinforcements are presented at fixed time period. provided that the appropriate response is made
Fixed Interval Schdule
an operand condition principle in which behavior is einforced based on average time that has expored since the last reinforcement.
fixed ratio schedule
an operant condition principle in which the delivery of reinforcements is based on particular average number of responses
Variable ratio schedule
an operant conditioning principle in which only some of the responses made are followed by reinforcement
intermittent reinforcement
the fact that operatnt behaviors that are maintained under intermittent reinforcement schedules resist extrinction better than those maintained under continous reinforcement
intermittent reinforcement effect
a condition in which somethin is learned but it is not manifested as a behavioral change until sometime in the future
latent learning
a condition in which learning takes place by watching the actions of others
observational learning
learning that takes place alrgely independent of awareness of both the process and the prducts of information acquisition
