Which of the following is an example of stimulus discrimination? a) conditioned to drool when a bell rings and being able to tell the difference between the sound of a ringing bell and the sound of a whistle b) conditioned to associate a bell ringing with food, drooling when the bell rings c) conditioned to drool only when food is paired with a bell d) conditioned to tell the difference between the sound of the bell and the taste of the food

C) conditioned to drool only when food is paired with a bell

Explanation:

Stimulus discrimination occurs when a certain stimulus is no longer associated with its original response.  This could only happen when we associate that stimuli with a specific type of situation after we encounter it over and over again.

For example, the sound of a bell usually give no effect to a dog.  But if we give the dog some food every time we ring a bell, that dog will eventually associate the sound of the bell with food. In the long run, the dog will drool every time it hears a bell.
