Term

Definition
relationship in time
Term
Contingency
Definition
consistency and reliability
Term
Conditioned
Definition
The process that establishes or strengthens a conditioned response is called
Term
Extinction
Definition
To extinguish a classically conditioned response, the conditioned stimulus is repeatedly presented without the unconditioned stimulus. This decrease and elimination is referred to as...
Term
Spontaneous Recovery
Definition
The temporary return of an extinguished response is called...
Term
Stimulus Generalization
Definition
is the extension of a conditioned response from the training stimulus to similar stimuli
Term
Discrimination
Definition
is the process of learning to respond differently to two stimuli because they produce two different outcomes.
Term
Operant conditioning
Definition
the process of changing behavior by following a response with a reinforcement or punishment
Term
Thorndike
Definition
Discovered operant conditioning. Put cats in a puzzle box.
Term
Shaping
Definition
establishes new responses by reinforcing successive approximations to it.
Term
Skinner
Definition
----used an "operant chamber" into which he put the animal he wished to train by shaping.
Term
Reinforcement
Definition
an event that increases the probability that a response will be repeated
Term
Positive Reinforcement
Definition
when a particular response results in the addition of something good
Term
Negative reinforcement
Definition
when a particular response results in the removal of something bad
Term
Primary reinforces
Definition
meet primary, biological needs and are found to be reinforcing for almost everyone.
Term
Secondary reinforcers

are associated with unconditioned reinforcers
Term
Punishment
Definition
an event that decreases the probability of a response
Term
Positive Punishment
Definition
addition of something that decreases behavior
Term
Negative punishment
Definition
when you take something away and that has the effect also of decreasing the behavior
Term
Schedule of Reinforcement
Definition
a set of procedures for delivery of reinforcement
Term
continuous reinforcement schedule
Definition
provides reinforcement every time a response occurs
Term
Fixed-ratio schedule
Definition
provides reinforcement only after a certain ("fixed") number of correct responses have been made.
-slower extinction, high rates of responding
Term
variable-ratio schedule
Definition
provides reinforcement after a variable number of correct responses, usually working out to an average in the long run
-even slower rates of extinction, high rates of responding
Term
fixed-interval schedule
Definition
provides reinforcement for the first response made after a specific time interval
-most of responding occurs right around time reward is due with pauses after reward
Term
variable-interval schedule
Definition
provides reinforcement after a variable amount of time has elapsed
-produces steady rates of responding and is highly resistant to extinction
Term
Acquisition
Definition
is the conditioning of response.
-Behavior increases because it is reinforced
Term
Extinction
Definition
occurs if responses stop producing reinforcements.
Term
Stimulus generalization
Definition
occurs when a new stimulus is similar to the original reinforced stimulus.

states that we learn about many behaviors before we attempt them for the first time
Term
Albert Bandura

defined the social-learning theory
Term

Term
Memory
Definition
a general term for the storage, retention and recall of events, information and procedures.
Term
Encoding (acquisition)
Definition
-converting external, sensory information into your memory.
-if things are not attended to, they will not be encoded and thus they will not be remembered.
Term
store
Definition
the process of keeping or maintaining information in memory
Term
access
Definition
this involves getting the information that we have stored back out.
Term
Atkinson&Shriffin Model
Definition
memory model suggest that incoming information is processed by 3 storage systems
Term
Sensory Memory
Definition
Incoming informaiton is briefly held and processes by a sensory memory, as an exact copy of the stimulus presented.
Term
Short-term memory
Definition
temporary storage of information that someone has just encountered.
-infor may be new or old
-limited capacity- 7 +-2
Term
Maintenance Rehearsal
Definition
repeating information over and over again until it is no longer needed
Term
Elaborative Rehearsal
Definition
a memory strategy that involves relating new information to something that is already known
Term
Long Term Memory
Definition
the memory system with virtually unlimited capacity that contains vast stores of a person's permanent or relatively permanent memories.
Term
Episodic memories
Definition
knowledge about things that happened to you
Term
semantic memories
Definition
knowledge about general things in the world
Term
working memory
Definition
a revised concept of the intermediate stage between our first encounter with new information and its eventual storage

Definition
producing required information by searching memory
-short answer questions
Term
recognition
Definition
identifying material as familiar or as having been encountered before
Term
Levels of processing principle
Definition
states that the ease with which we can retrieve a memory depends on the number and types of associations that we form with that memory.
Term
Encoding specificity principle
Definition
shows how memories are linked to the context where they are created.
Term
Context-dependent memory
Definition
A form of state-dependent memory associated with the context in which information is learned and recalled.
Term
