Term
Learning
Definition

a relatively permanent change in behavior, knowlege, capability, or attitude that is acquired through experience and can not be attributed to illness, injury, or maturation

Term
classical/respondant condition
Definition
a type of learning through which an organism learns to associate one stimulus with another
Term
stimulus
Definition
(plural is stimuli) is any event or object in the environment to which an organism responds.
Term
reflex
Definition
an involuntary responce to a particular stimilis such as salivation in responce to food placed in the mouth and the eyeblink responce to a puff of air. 

conditioned- learned
unconditioned- unlearned
Term
unconditioned response
Definition
a response that is elicited by an unconditioned stimulus without prior learning
Term
unconditioned stimulus
Definition
any stimulus such as food, that without prior learning will automaticall elict, or bring forth, an unconditioned responce
Term
conditioned stimuls
Definition
is a neutral stimulus that, after repeated pairing with an unconditioned stimuls, becasue associated with it and elicits a conditioned response
Term
conditioned response
Definition
is the learned response that comes to elicited by a conditioned stimulus as a result of repeated pairing with an unconditioned stimulus
Term
extinction
Definition
the process in which in classical conditioning the weakening and eventual disappearance of the conditioned response as a result of repated presentation of the conditioned stumulus without the unconditioned stimulus
Term
spontaneous recovery
Definition
the reappearance of an extinguished response (in a wearker form) when an organism is exposed to the original conditioned stimulus following a rest period.
Term
stimulus generalization
Definition
in classical conditioning, the tendency to make conditined response to a stimulus that is similar to the original conditioned stimulus
Term
stimulus discrimination
Definition
the learned ability to distinguish between similar stimuli so that the conditioned response occurs only to the original conditioned stimuli but not similar stimuli
Term
Thorndike
Definition
American psychologist, troal and error learning si the basis of most behavioral changes
Term
Law of effect
Definition
states that the consequene, or effect, of a response will determine whether the tendency to respond in the same way in the future will be strengthened or weakened
Term
operant conditioning
Definition
the consequences of behavior are manipulated in order to increase or decrease the frequency of an excisting response or to shape an entirely new response
Term
reinforcer
Definition
is anything that strengthens or increases the probability of the response it follows
Term
shaping
Definition
is an operant conditioning technique that consists of gradually molding a desired behavior (response)  by reinforcing any movement in the direction of the desired response, thereby gradually guiding the responses toward the ultimate goal
Term
extinction
Definition
occurs when reinforcers are withheld and the conditioned response weakens and eventualy disapears
Term
stimulus generalization
Definition
occurs in operant conditioning; the tendency to make the learned response to a stimuls similar to that for which the response was originally reinforced
Term
disctiminative stimulus
Definition
a stimulus that signals wheather a certain response or behavior is likely to be reqarded, ignored, or punished
Term
reinforcement
Definition
a key concept in operant conditioning and may be defined as any event that follows a response and strengthens or increases the probability of the response being repeated
Term
positive reinforcement
Definition
which is roughly the same thing as reward, refres to any pleasant or desirable consequence that follows a response and increases the probability that the responces will be repeated
Term
negative reinforcement
Definition
a person or animals behavior is reinforced by the termination or avoidance of an unpleased conditioin
Term
primary reinforcer
Definition
one that fulfills a basic physical need for survival and does not depend on learning
Term
seconday reinforcer
Definition
is acquired or learned though association with other reinforcers.
Term
punishement
Definition
is the opposite of reinforcement and usually lowers the probability of a response by following it with an aversive or unpleased consequence
Term
encoding
Definition
the transformation of information into a form that can be stored
Term
consolidation
Definition

the process for encoded information to be stored, some physiological change must take place in the brain

Term
storage
Definition
involves keeping or maintaining information
Term
retrieval
Definition
occurs when information is brought to the mind
Term
Atkinson-Shiffrin Model
Definition
widely accepted information process..

there are three differnt, interatcting memory systems:
sensory memory, short term memory, and long term memory.
Term
sensory memory
Definition
the memory system that holds information from the senses for a period of time ranging from only a fraction of a second to about 2 secs
Term
short term memory
Definition
usually codes information according to sound and holds about seven plus or minus two, differnt items or bits of information at one time
Term
long term memory
Definition
is a persons vast storehouse of permanent or relatively permant memories
Term
chunking
Definition
organizing or grouping separate bits of information into larger units or chunks
Term
rehearsal
Definition
items in short term memory are lost in less than 30 seoncds unless you repeated them over and over to yourself
Term
elaborative rehearsal
Definition
which invoves relating new information to something you already know
Term
declarative memory
Definition
also called explicit memory
stores facts, informatiion and perosnal life events that can be brought to mind verbally or in the form of imges and then declared or stated
Term
non declarative memory
Definition
aka implicit memory

is the subsystem within long term memory that stores motor skills, habits, and simple classically conditioned responses.
Term
episodic memory
Definition
is the type of declarative memory that records events as they have been subjectively experienced
Term
semantic memory
Definition
the other type of declarative memory, is memory for general knowledge, or objective faces and informantion
Term
levels of processing model
Definition
suggested that weather peoplse remember something for a few seconds or a life time depends on how deeply they process the infotmation
Term
retrieval cue
Definition
is any stimulus or bit of information that aids in retrieving a particular memory
Term

recall

Definition
a person must produce required information simply by searching memory
Term
recognition
Definition
is exctly what the name implies.. a memory task in whihc a person must simply indentify material as familiar (face, name, task, melody) or having been encountered before
