Classical Conditiong
a learning procedure in which assocuations are made between a neutral stimulus and an unconditioned stimulus
-
neutral stimulus
a stimuls that does not initially any part of an unconditioned response
-
unconditioned stimulus (US)
an event that elicits a certain predictable response typically without previous training
-
unconditioned response (UR)
an organism's automatic( or natural) reaction to a stimulus
-
conditioned stimuls (CS)
a once neutral event that elicits a given response after a period of trainging in which it has been paired with (occurred just before) an unconditioned stimulus
-
Conditioned response (CR)
the learned reaction to a conditioned stimulus
-
generalization
responding similarly to a range of similar stimuli
-
discrimination
the ability to respond differently to similar but distinct stimuli
-
extinction
the gradual dissappearance of a conditioned response when the conditioned stimulus is repeatedly presented without the unconditioned stimulus
-
operant conditioning
learning in which a certain action is reinforced or punished, resulting in corresponding increases or decreases in occurrence
-
reinforcement
stimulus or event that follows a response and increase the likelihood that the response will be repeated
-
primary reinforcer
stimulus that is naturally rewarding, such as food or water
-
secondary reinforcer
stimulus such as money that becomes rewarding through its link with a primary reinforcer
-
fixed-ratio schedule
a pattern of reinforcement in which a specific number of correct reponses is required before reinforcement can be obtained
-
variable-ratio schedule
a pattern of reinforcement in whcih an unpredictable number of responses are required before reinforcemtn can be obtained
-
fixed-interval schedule
a pattern of reinforcement in which a specific amount of time must elapse before a response will elicit reinforcement
-
variable-interval schedule
a pattern of reinforcement in which changing amounts of time must elapse before a response will obtain reinforcement
-
shaping
technique in which the desired behavior is "molded" by first rewarding any act similar to that behavior and then requiring ever-closer approximations to the desired behavior before giving the reward
-
response chain
learned reactions that follow one another in srquence, each reaction producing the signal for the next
-
aversive control
process of influencing behavior by means of unpleasant stimuli
-
negative reinforcement
increasing the strength of a given response by removing or preventing a painful stimulus when the response occurs
-
escape conditioning
training of an organism to remove or terminate an unpleasant stimulus
-
avoidance conditioning
training of an organism to respond so as to prevent the occurence of an unpleasant stimulus
-
social learing
process of altering behavior by observing and imitation the behavior of others
-
cognitive learning
form of altering behavior that involves mental processes and may result from observation or imitation
-
cognitive map
a mental picture of spatial relationships or relationships between events
-
latent learning
alteration of a behavioral tendency that is not demonstrated by an immediate, observable cange in behavior
-
learned helplessness
condition in which repreated attempts to contol a situation fail, resulting in the belief that the situation is uncontrollable
-
modeling
learning by imitating others; copying behavior
-
bhavior modification
systematic application of learning principles to change people's actions and feelings
-
token economy
conditioning in which desirable behavior is reinforced with valueless objects, which can be accumulated and exchanged for values rewards
-
memory
the input, storage, and retreival of what has been learned or experienced
-
encoding
the transforming of information so the nervous system can process it.
-
storage
the process by which information is maintained over a period of time
-
retreival
the process of obtaining information that has been stored in the memory
-
sensory memory
very brief memory storage immediately following initial stimulation of a receptor
-
short-term memory
memory that is limited in capactiy to about seven items and in duration by the subject's active rehersal
-
maintenance rehersal
a system for remembering that involves repeating information to oneself without attempting to find meaning in it
-
chunking
the process of grouping items to make them easier to remember
-
semantic memory
knowledge of language, including its rules, words, and meanings
-
episodic memory
chronological retention of the events of one's life
-
declarative memory
stored knowledge that can be called forth consciously as needed
-
procedural memory
permanent storage learned skills that does not require conscious recollection
-
recognition
memory retreival in which a person identifies an object, idea, or situation as one he or she has or has not experienced before
-
recall
memory retreival in which a person reconstructs perviously learned material
-
reconstructive processes
the alteration of a recalled memory that may be simplified, enriched, or distorted, depending on an individual's experiences, attitudes, or inferences
-
confabulation
the act of filling in memory gaps
-
schemas
conceptual frameworks a person uses to make sense of the world
-
eidetic memory
the ability to remember with great accuracy visual information on the basis of short-term exposure
-
decay
fading away of memory over time
-
interference
blockage of a memory by previous or subsequent memories or loss of a retreival clue
-
elaborative rehersal
the linking of new information to material that is already known
-
mnemonic devices
techniques for using asoociations to memorize and retrieve information
