Reading Comprehension

One of the many theories about alcoholism is the learning and reinforcement theory, which explains alcoholism by considering alcohol ingestion as a reflex response to some stimulus and as a way to reduce an inner drive state such as fear or anxiety. Characterizing life situations in terms of approach and avoidance, this theory holds that persons tend to be drawn to pleasant situations and repelled by unpleasant ones. In the latter case, alcohol ingestion is said to reduce the tension or feelings of unpleasantness and to replace them with the feeling of euphoria generally observed in most persons after they have consumed one or more drinks.

Some experimental evidence tends to show that alcohol reduces fear in the approach-avoidance situation. Conger trained one group of rats to approach a food goal and, using aversion conditioning, trained another group to avoid electric shock. After an injection of alcohol the pull away from the shock was measurable weaker, while the pull toward the food was unchanged.


It can be inferred from the passage that aversion conditioning is based primarily on the principle that
(A) electric shock stimulates a response
(B) behavior that is punished will be avoided
(C) pain is a stronger stimulus than pleasure
(D) alcohol reduces fear
(E) behavior that is rewarded will be repeated

B or D

IMO B.

I think in an inference question answer is not explicitly stated in the passage. hence D cannot be the answer.
Also, author restates "using aversion..." which means it is difference from what is stated in the before line.

what is OA?

OA B

Dear adi_800, What is the source of this question? I chose 'B'.

Guys i am not able to understand the phrase
'After an injection of alcohol the pull away from the shock was measurable weaker' what does this mean?

IMO D
I don't particularly think that answers to inference questions cannot be explicitly stated in the paragraph....

imo a better way to support your answer would be to analyze the question and either eliminate the other answers or support the correct answer.

The key words -- aversion conditioning -- is an act of pulling away from something you should. In this case pull away from electric shock. The trained brain will induce fear to instigate the reaction. But alcohol may reduce the fear..therefore the rat's 'pull away' reaction has become considerably weaker.

I would double check the OA or provide a more prudent explanation to support the answer B

Here is the complete passage:
One of the many theories about alcoholism is the learning and reinforcement theory, which explains alcoholism by considering alcohol ingestion as a reflex response to some stimulus and as a way to reduce an inner drive state such as fear or anxiety. Characterizing life situations in terms of approach and avoidance, this theory holds that persons tend to be drawn to pleasant situations and repelled by unpleasant ones. In the latter case, alcohol ingestion is said to reduce the tension or feelings of unpleasantness and to replace them with the feeling of euphoria generally observed in most persons after they have consumed one or more drinks.
Some experimental evidence tends to show that alcohol reduces fear in the approach-avoidance situation. Conger trained one group of rats to approach a food goal and, using aversion conditioning, trained another group to avoid electric shock. After an injection of alcohol the pull away from the shock was measurable weaker, while the pull toward the food was unchanged.
The obvious troubles experienced by alcoholic persons appear to contradict the learning theory in the explanation of alcoholism. The discomfort, pain, and punishment they experience should presumably serve as a deterrent to drinking. The fact that alcoholic persons continue to drink in the face of family discord, loss of employment, illness, and other sequels of repeated bouts is explained by the proximity of the drive reduction to the consumption of alcohol; that is, alcohol has the immediate effect of reducing tension while the unpleasant consequences of drunken behavior come only later. The learning paradigm, therefore, favors the establishment and repetition of the resort to alcohol.
In fact, the anxieties and feelings of guilt induced by the consequences of excessive alcohol ingestion may themselves become the signal for another bout of alcohol abuse. The way in which the cue for another bout could be the anxiety itself is explained by the process of stimulus generalization: conditions or events occurring at the time of reinforcement tend to acquire the characteristics of state of anxiety or fear, the emotional state itself takes on the properties of a stimulus, thus triggering another drinking bout.
The role of punishment is becoming increasingly important in formulating a cause of alcoholism based on the principles of learning theory. While punishment may serve to suppress a response, experiments have shown that in some cases it can serve as a reward and reinforce the behavior. Thus if the alcoholic person has learned to drink under conditions of both reward and punishment, either type of condition may precipitate renewed drinking.
Ample experimental evidence supports the hypothesis that excessive alcohol consumption can be learned. By gradually increasing the concentration of alcohol in drinking water, psychologists have been able to induce the ingestion of larger amounts of alcohol by an animal than would be normally consumed. Other researchers have been able to achieve similar results by varying the schedule of reinforcement-that is, by requiring the animal to consume larger and larger amounts of the alcohol solutions before rewarding it. In this manner, animals learn to drink enough to become dependent on alcohol in terms of demonstrating withdrawal symptoms.

(B) Which has proven more effective in the treatment of alcoholism, aversion conditioning or reinforcement?

Wish you all a pleasant RC mastering journey

The answer could not be inferred from the passage, rather it had to be done from its meaning...
Doesn't seem like a typical GMAT question, this one...don't you think?

It wants inferred from the passage..not fully stated in the passage

So (B) is the answer

The question was misleading especially after having looked at only part of the passage on the first page. After I re-read the entire passage in page 2 it made more sense in context. Please post the entire passage for reading comprehension questions.

Aversion Conditioning can be inferred from this line "using aversion conditioning, trained another group to avoid electric shock". So, Aversion Conditioning is used to teach someone to abstain from a behaviour that will give negative results.

That is what is stated in B "behavior that is punished will be avoided".

For this question, we need only this one line, not the entire passage.

B is the right answer I think
