Document Summary
when the sd is present, the behaviour is reinforced. when any other antecedent stimuli except the sd are present, the behaviour is not reinforced. During discrimination, any antecedent behaviour that is present when behaviour is not reinforced is called an s- Delta (s ) y as a result of discrimination training, a behaviour is more likely to occur in the future y when an sd is present but less likely to occur when an s is present (stimulus control) If a behaviour is punished in the presence of one antecedent stimulus, the behaviour will decrease/stop occurring in the future when that stimulus is present (ex: when the soup was boiling, you took a spoonful and burnt your tongue. In the future, you will not taste soup when it is boiling- boiling soup is the sd) y according to skinner, stimulus discrimination training involves a three-term.
