In classical conditioning, discrimination is the ability to differentiate between a conditioned stimulus and other stimuli that have not been paired with an unconditioned stimulus.For example, if a bell tone were the conditioned stimulus, discrimination would involve being able to tell the difference between the bell sound and other similar sounds.
Discriminative Stimulus. Discriminative stimulus is a term used in classical conditioning as a part of the process known as operant conditioning. A discriminative stimulus is a type of stimulus that is used consistently to gain a specific response and that increases the possibility that the desired response will occur.
What is a Discriminative Stimulus? As the intoductory quote states, the discriminative stimulus is ‘a stimulus in the presence of which a particular response will be reinforced’ (Malott, 2007, p. 202). Before getting into more detail on this, we're going to use an anology to describe the discriminative stimulus (and the stimulus delta).
Stimulus discrimination occurs in psychology when there are different consequences for the same behavior depending on the situation. An example of a stimulus discrimination is a joke that could be told with the result of laughter among a group of friends, but the same joke may have repatriation if it is told in a church hall setting.
An S+ is a discriminative stimulus that tells an animal reinforcement is available. An S- is a discriminative stimulus that tells an animal reinforcement is not available. Animals quickly learn to approach an S+ and avoid an S-. A stimulus is made into an S+ by consistently following it with reinforcement.
Psychology Definition of DISCRIMINATIVE STIMULUS: Operant conditioning. A stimulus that increases the probablity of a response.
An observing response is sometimes necessary for presentation of the discriminative stimulus/stimuli. For example, different individuals can serve as discriminative stimuli in a joke-telling situation. The jokes that you tell your priest are probably different from the jokes that you tell your best friend because of your past history of telling ...

The discriminative stimulus is the cue (stimulus) that is present when the behavior is reinforced. The animal learns to exhibit the behavior in the presence of the discriminative stimulus. In the example above, the red circle was the discriminative stimulus (sometimes abbreviated S D, pronounced "S-Dee".)
