Classical conditioning occurs when a conditioned stimulus (CS) is paired with an unconditioned stimulus (US). Usually, the conditioned stimulus is a neutral stimulus (e.g., the sound of a tuning fork), the unconditioned stimulus is biologically potent (e.g., the taste of food) and the unconditioned response (UR) to the unconditioned stimulus is an unlearned reflex response (e.g., salivation).
The additional learned response of the rat turning to the front of the box in reaction to the scratching is an effect of external inhibition, which may have added to the latent time, but the results do not indicate what portion of the rat’s turn-around response made up the latent time.
This sound was presented to the dogs along with food, which acted as an unconditioned stimulus. The presentation of a neutral stimulus does not result in any particular response, but the presentation of an unconditioned stimulus results in an unconditioned response, which was the dogs salivating in Pavlov's experiments.
The unconditioned stimulus is the dog's food that would naturally cause salivation, which is an unconditioned response. Pavlov then trained the dog by ringing the bell every time before food. The conditioned stimulus is the ringing bell after training, which causes salivation as a conditioned response. [3] [page needed]
Response can be twofold: the extracellular matrix, for example, is a conductor of mechanical forces but its structure and composition is also influenced by the cellular responses to those same applied or endogenously generated forces. [10]
For example, as a result of training, INP cells discharge prior to CR execution and fire in a pattern of increased frequency of response that predicts the temporal form of the behavioral CR (McCormick & Thompson, 1984). This pattern of activity clearly indicates that the INP is capable a generating a conditioned response.
Response to stimuli: a response can take many forms, from the contraction of a unicellular organism to external chemicals, to complex reactions involving all the senses of multicellular organisms. A response is often expressed by motion; for example, the leaves of a plant turning toward the sun (phototropism), and chemotaxis.
Spontaneous recovery is associated with classical conditioning, a learning process in which an organism learns to associate a neutral stimulus with a stimulus that produces an unconditioned response. As a result, the previously neutral stimulus comes to produce its own response, which is usually similar to that produced by the unconditioned ...
