Learning
|
Some experience that results in relatively permanent change in the state of the learner.
|
Habituation
|
A general process in which repeated or prolonged exposure to a stimulus results in a gradual reduction response.
|
Classical Conditioning
|
When a neutral stimulus evokes a response after being paired with a stimulus that naturally evokes a response.
|
Unconditioned Stimulus (US) |
Something that reliably produces a naturally occurring reaction in an organism.
|
Unconditioned Response (UR) |
A reflexive reaction that is reliably elicited by an unconditioned stimulus.
|
Conditioned Stimulus (CS) |
A stimulus that is initially neutral and produces no reliable response in an organism.
|
Conditioned Response (CR) |
A reaction that resembles an UR but is produces by a CS.
|
Acquisition
|
The phase of classical conditioning when the CS and the US are presented together.
|
Extinction
|
The gradual elimination of a learned response that occurs when the US is no longer presented.
|
Spontaneous Recovery |
The tendency of a learned behavior to recover from extinction after a rest period.
|
Generalization |
The CR is observed even though the CS is slightly different from the original one used during acquisition.
|
Discrimination |
The capacity to distinguish between similar but distinct stimuli.
|
Biological Preparedness
|
A propensity for learning particular kind of associations over others.
|
Operant Conditioning
|
A type of learning in which the consequences of an organism's behavior determine whether it will be repeated in the future.
|
Law of Effect
|
The principle that behaviors that are followed by a "satisfying state of affairs" tend to be repeated and those that produce an "unpleasant state of affairs" are less likely to be repeated.
