Final answer:
Stimulus discrimination and stimulus generalization are learning processes used to determine which stimuli trigger learned responses. In this scenario, the child is asked to select the circle after being exposed to round and triangle shapes, which is an example of stimulus discrimination.
Step-by-step explanation:
Stimulus discrimination and stimulus generalization are learning processes involved in determining which stimuli will trigger learned responses. When an organism learns to respond differently to similar stimuli, it is called stimulus discrimination.
On the other hand, when an organism demonstrates the conditioned response to stimuli that are similar to the conditioned stimulus, it is called stimulus generalization. In the scenario described, pairing round and triangle shapes and asking the child to select the circle is an example of stimulus discrimination.
