Question

Which is the example of conditioned reflex?

• A. Eyes closed when anything enter into it.
• B. Hand took up when pierced with a needle.
• C. Salivation in a hungry dog in response to ringing of a bell.
• D. Digested food goes forward in alimentary canal.

Answer 1

Answer: (C)

Salivation in a hungry dog in response to ringing of a bell.

There are two different forms of reflexes, conditioned and unconditioned reflex. Unconditioned reflex is the response obtained on a given stimulus. Eyes closing, moving the hand away and food digestion are the forms of unconditioned reflexes. In case of conditioned reflex, the stimulus is associated with another stimulus and response is generated. The dog has associated the ringing of bell and offering of food with each other. So, when the bell is rang, the dog salivates with the memory that food has been provided.

So, the correct answer is option C.
