When you were a child, your mother always made you chocolate chip cookies when you were sad, cheering you up. As an adult, whene
yawa3891 [41]

Answer:

UCS = chocolate chip cookies

CS = the smell

UCR = the smell of chocolate cookies

CR = the smell of chocolate chips cookies makes you happier

Explanation:

Classical conditioning has three basic stages. The first stage is before conditioning stage in which the unconditioned stimulus (UCS) produces a unlearned response, also called the unconditioned response (UCR. This response is natural.

The second stage is the "during conditioning stage" and it involves a stimulus producing no response and has an association with the unconditioned stimulus, which now becomes the conditioned stimulus (CS).

The third and final stage is the "after conditioning" stage and in this stage the CS is now associated with the UCS to produce a Conditioned response (CR).

From the example, the Unconditioned Stimulus (UCS) is the chocolate chip cookies which produces an unlearned response of cheering you up.

The conditioned stimulus is the smell of the chocolate which is now associated with the UCS to become the CS.

The Unconditioned response is the smell f the chocolate chip cookies, which the conditioned response is the smell of the chocolate chip cookies that makes you happy. The happiness is the conditioned response. You are not used feeling happy once you perceive the smell of chocolate chip cookies.

Write a letter to a electricity authority requesting a regular supply of electricity in your society.​
Anon25 [30]

Answer:             I, on behalf of my locality, with to draw your kind attention towards frequent breakdown of electricity in Rainak Bazar Area. The low voltage and frequent tripping of electricity in this area has become almost a daily routine. During the three hour daily cut, no one expects the supply of electricity. But the unannounced frequent breakdown of electricity is simply nightmarish. At night, one is left half through the meals at the dining table. During the day, there is no rest, no comfort, no protection from the sultry weather.

           Besides this, low voltage of electricity has damaged electric lamps, tubes and other electric appliances. Fans do not give proper air owing to low voltage. Many times complaints have been lodged with your office but no permanent solution to this menace has been found. It is a pity that even when there is supply of electricity in other localities, our locality remains dark. The wires through which electricity is supplied to our locality, are old and worn out, the transformer where from the electricity is supplied to us, is also an old one. There is always some defect in wires or in the transformer. In fact, all the wires as well as the transformer need to be replaced. Only then the proper supply of electricity can be restored to this locality.

           I hope you would look into the matter at the earliest and redress our grievance.
