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).
Most people with autism are thought to have especially low levels of latent inhibition. Depending on their intelligence and social skills , it can often lead to sensory overload . More generally: those of above average intelligence are thought to be capable of processing this stream effectively, enabling their creativity and increasing their ...
Central to operant conditioning is the use of a Three-Term Contingency (Discriminative Stimulus, Response, Reinforcing Stimulus) to describe functional relationships in the control of behavior. Discriminative stimulus (S D) is a cue or stimulus context that sets the occasion for a response. For example, food on a plate sets the occasion for eating.
Discrete trials were originally used by people studying classical conditioning to demonstrate stimulus–stimulus pairing. [citation needed] Discrete trials are often contrasted with free operant procedures, like ones used by B.F. Skinner in learning experiments with rats and pigeons, to show how learning was influenced by rates of reinforcement.
Van Hamme and Wasserman have extended the original Rescorla–Wagner (RW) model and introduced a new factor in their revised RW model in 1994: [3] They suggested that not only conditioned stimuli physically present on a given trial can undergo changes in their associative strength, the associative value of a CS can also be altered by a within-compound-association with a CS present on that trial.
This type of learning is used in studies regarding operant and classical conditioning. Operant conditioning involves the modification of a behavior by means of reinforcement or punishment. In this way, a discriminative stimulus will act as an indicator to when a behavior will persist and when it will not.

Spontaneous recovery is a phenomenon of learning and memory that was first named and described by Ivan Pavlov in his studies of classical (Pavlovian) conditioning.In that context, it refers to the re-emergence of a previously extinguished conditioned response after a delay. [1]
