Question

12.      A researcher performs the following classical conditioning experiment on several subjects. The experimental procedure for each subject is the same:

Subject relaxes for two minutes

Subject’s pulse is taken.

Researcher taps a pencil on a desk five times

Subject performs jumping jacks for 30 seconds

Subject’s pulse is taken

Repeat steps 1-5 ten times

After two minutes of rest, the researcher taps a pencil on a desk five times, then takes the subject’s pulse without exercising.

A.        Identify the conditioned stimulus, unconditioned stimulus, conditioned reflex/response, and unconditioned reflex/response.

B.        If conditioning is successful, what would you expect the result of the final pulse measurement (in step 7) to be? Briefly explain your reasoning in 1 sentence.

Explanation / Answer

A. (i) Conditioned reflux is: Researcher taps a pencil on a desk five times

(ii) unconditioned stimulus: Subject relaxes for two minutes

(iii) conditioned reflex/response: After two minutes of rest, the researcher taps a pencil on a desk five times, then takes the subject’s pulse without exercising.

(iv) unconditioned reflex/response: Subject performs jumping jacks for 30 seconds

B. If conditioning is successful, then subject pulse rate will increase as it start doing jumping jack after researcher taps a pencile.
