An adaptive process in which the tendency to perform a particular behaviour is changed by experience.
The behavioural change produced by the internal changes brought about by learning.
Any response by which an organism directs appropriate sensory organs (eyes, ears, nose) toward the source of a novel stimulus.
The simplest form of learning; learning not to respond to an unimportant event that occurs repeatedly
The process by which a response normally elicited by one stimulus (the unconditional stimulus or UCS) comes to be controlled by another stimulus (the conditional stimulus or CS) as well.
unconditional stimulus (UCS)
In classical conditioning, a stimulus, such as food, that naturally elicits a reflexive response, such as salivation
unconditional response (UCR)
In classical conditioning, a response, such as salivation, that is naturally elicited by the UCS.
conditional stimulus (CS)
In classical conditioning, a stimulus that, because of its repeated association with the UCS, eventually elicits a conditional response (CR).
conditional response (CR)
In classical conditioning, the response elicited
by the CS.
In classical conditioning, the time during which a CR first appears and increases in frequency.
In classical conditioning, the elimination of a response that occurs when the CS is repeatedly presented without being followed by the UCS.
After an interval of time, the reappearance of a response that had previously been extinguished.
In classical conditioning, CRs elicited by stimuli that resemble the CS used in training.
In classical conditioning, the appearance of a CR when one stimulus is presented (the CS+) but not another (the CS )
Unreasonable fear of specific objects or situations, such as insects, animals, or enclosed spaces, learned through classical conditioning.
The prevention of or attenuation in learning that occurs to a neutral CS when it is conditioned in the presence of a previously conditioned stimulus.
inhibitory conditional response
A response tendency conditioned to a signal that predicts the absence of the UCS; generally not observed directly but assessed though other tests.
excitatory conditional response
A response tendency conditioned to a signal that the UCS is about to occur. This is the type of CR exemplified by Pavlov s salivation response.
A form of learning in which behaviour is affected by its consequences. Favourable consequences strengthen the behaviour and
unfavourable consequences weaken the behaviour

In operant conditioning, the stimulus that sets
the occasion for responding because, in the past, a behaviour has produced certain consequences in the presence of that stimulus.
The relation among discriminative stimuli,
behaviour, and the consequences of that behaviour. A motivated organism emits a specific response in the presence of a discriminative stimulus because, in the past, that response has been reinforced only when the discriminative stimulus is present.

A decrease in the frequency of a response that is regularly and reliably followed by the termination of an appetitive stimulus.
A decrease in the frequency of a previously reinforced response because it is no longer followed by a reinforcer
The reinforcement of behaviour that successively approximates the desired response until that response is fully acquired.
The occasional reinforcement of a particular
behaviour; produces responding that is more resistant to extinction
A schedule of reinforcement in which reinforcement occurs only after a fixed number of responses have been made since the previous reinforcement (or the start of the session
A schedule of reinforcement similar to a fixed ratio schedule but characterized by a variable response requirement having
a particular mean.
A schedule of reinforcement in which the first
response that is made after a fixed interval of time since the previous reinforcement (or the start of the session) is reinforced.
A schedule of reinforcement similar to a fixed interval schedule but characterized by a variable time requirement having a particular mean.
In operant conditioning, the occurrence of responding when a stimulus similar (but not identical) to the discriminative stimulus is present
In operant conditioning, responding only when a specific discriminative stimulus is present but not when similar stimuli are present
A biologically significant appetitive stimulus, such as food or water.
A biologically significant aversive stimulus, such as pain
conditioned (or secondary) reinforcer (or punisher
A stimulus that acquires its reinforcing (or punishing) properties through association with
a primary reinforcer (or punisher). Sometimes referred to as a secondary reinforcer (or punisher).
An operant response acquired through negative reinforcement that terminates an aversive stimulus
An operant response acquired through negative reinforcement that prevents an aversive stimulus from occurring.

string of letters GSTCBCRCMP are easier to remember if a person learns the rule that organizes them into smaller chunks : GST, CBC, and RCMP.
phonological short-term memory
Short-term memory for verbal information.
An unvoiced speech utterance.
An inability to remember words that are heard,
although they usually can be understood and responded to appropriately. This disability is caused by damage to Wernicke s and Broca s areas.
The process by which information in short-term memory changes to long-term memory, presumably because of physical changes that occur in neurons in the brain.
