Final answer:
The occurrence of behavior in the presence of stimuli that are similar to the discriminative stimulus presented during training is known as stimulus generalization.
Step-by-step explanation:
In psychology, the occurrence of behavior in the presence of stimuli that are similar to the discriminative stimulus presented during training is known as stimulus generalization. Stimulus generalization refers to the tendency for a learned response to occur in the presence of stimuli that are similar or resemble the original conditioned stimulus.
An example of stimulus generalization is Pavlov's dogs, who responded to other similar tones with salivation even though they had only been conditioned with a specific tone.
Another example is Tiger the cat, who discriminates between the sound of an electric can opener and an electric mixer, responding only to the sound of the can opener because it predicts the arrival of food.
