S-delta. The S-delta (SD) is the stimulus in the presence of which the behavior is not reinforced. At first during discrimination training, the animal often responds in the presence of stimuli that are similar to the SD. These similar stimuli are S-deltas. Eventually, responding to the S-delta will be extinguished.

Stimulus discrimination training is a strategy that is used to teach an individual to engage in particular behaviors in the presence of certain situations, events, or stimuli.

discriminative stimulus

The stimulus delta is defined as ‘a stimulus in the presence of which a particular response will not be reinforced’ (Malott, 2007, p. 202).

S-delta -S(triangle) the behavior is not reinforced. less likely to occur when S(triangle) is present. Does SD cause a behavior to occur. no, it does not cause a behavior to occur.

spontaneous recovery. When a behavior occurs again after it had not occurred for some time due to extinction, the process is called. spontaneous recovery.

Def: Errorless discrimination training. A gradual training procedure that minimizes the number of errors (nonreinforced responses to the S delta) and reduces many of the adverse effects associated. What is the first aspect of errorless discrimination training?

The two stimulus parameters that determine whether a stimulus will acquire discriminative control are stimulus disparity (the magnitude between the positive and the negative stimulus/ physical difference) and stimulus salience (the magnitude of the difference between the discriminative stimuli and the background …
