Stimulus Discrimination Is Acquired By

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.

Stimulus discrimination is acquired by. Definitions for stimulus control. After the dog has been conditioned he might respond to a variety of sounds that are similar to the whistle. These experiments investigate whether the facilitative effect of naming on the acquisition of conditional discriminations in young children is due to enhancing discrimination of the sample and comparison stimuli or whether naming serves additional functions.

B reinforcing responses in the presence of both discriminative stimuli and stimulus deltas. Unlike perceptual learning however acquired distinctiveness appears to entail more than latent inhibition of shared stimulus features and mutual inhibition of unique features. The discriminative stimulus effects of nicotine which are extensively used as an animal correlate of subjective reports of nicotine effects in humans are mainly mediated by neuronal nicotinic acetylcholine receptors since the discrimination of nicotine can be blocked by mecamylamine a nicotinic receptor antagonist that penetrates the blood brain barrier but not by the nicotinic receptor antagonist hexamethonium which does not readily enter the brain.

S delta sδ a stimulus in the presence of which a particular response will not be reinforced or punished. However a subject can be taught to discriminate between similar stimuli and only to respond to a specific stimulus. A reinforcing responses in the presence of a stimulus delta and withholding reinforcement in the presence of the discriminative stimulus.

Discriminative stimulus sd a stimulus in the presence of which a particular response will be reinforced or punished. Discrimination training procedure reinforcing or punishing a response. 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.
