Question

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.   1

Hi,

For 3 :

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

Here we are talking about the principle, not the outcome. The principles is that rats should avoid electric shocks. The outcome is that alcohol reduces that fear. Principle is B.

As for 9 :

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.

The author goes to great troubles to explain why the opposition to the theory is not valid. He therefore is in support of the theory. Credible is the only positive tone given in the options.

Question 1 
 
To answer question 1, let's consider the purpose of each paragraph:

Paragraph 1 : To explain how "learning and reinforcement theory" can be used to describe the behavior of alcoholics (i.e. they drink to reduce the tension of unpleasant situations).    Paragraph 2 : To describe experimental evidence in rats that supports the idea that alcohol reduces fear in unpleasant situations, which in turns supports the point made in paragraph 1.    Paragraph 3 : To point out that alcoholics' behavior seems to contradict learning theory, though this apparent contradiction can be resolved since the "unpleasant consequences of drunken behavior come only later."    Paragraph 4 : To reinforce the idea that learning theory explains alcoholism, since the negative feelings caused by drinking can lead to more drinking, which helps reduce those negative feelings.    Paragraph 5 : To point out that punishment (i.e. negative experience) can trigger drinking, if punishment becomes associated with drinking.    Paragraph 6 : To present evidence supporting the idea that alcoholism can be learned, especially when it is rewarded (which is consistent with the learning and reinforcement theory).

Let's now consider question answer choice (D):

While the passage does this, it isn't the  ultimate  purpose. Note that the motivations for drinking are all discussed to  support  the idea that the "learning and reinforcement theory" relates to alcoholic behavior. So because it isn't the  primary  purpose, we can eliminate (D).

But what about (B)?

This sounds good. Many of the paragraphs discuss how alcoholic people behave. And these discussions serve to support the idea presented in the first paragraph, that alcoholic behavior can be explained in terms of the "learning and reinforcement theory." So (B) is correct.

I hope that helps!

Question 9 
 
To answer this question, let's see how the "learning and reinforcement theory" plays into the author's purpose in this passage.

In the first paragraph, the author explains how the "learning and reinforcement theory" can be used to describe the behavior of alcoholics (i.e. they drink to reduce the tension of unpleasant situations).   The second paragraph describes experimental evidence which supports the idea that the "learning and reinforcement theory" can describe alcoholic's behavior (when rats consume alcohol, they find electric shocks less unpleasant).   The third paragraph points out that although alcoholics' behavior  seems  to contradict learning theory, this apparent contradiction can be  resolved  since the "unpleasant consequences of drunken behavior come only later."   The last paragraph suggests that alcoholism can be learned, especially when it is rewarded (which is consistent with the learning and reinforcement theory).

Taken together, this shows that the author believes that "learning and reinforcement theory" can properly be applied to alcoholics.

Let's now consider the question and answer choices:

Since the author argues that the "learning and reinforcement theory" can be successfully applied to alcoholics, we know she/he thinks the theory is credible. That is, the theory has some merit. Let's hold onto (A).

The author thinks the theory can be applied to alcoholics. But does that make it  unassailable ? It's hard to say. The author doesn't analyze "learning and reinforcement theory" in depth, so we don't know if he/she considers it totally flawless. We just know that it can be applied properly to a certain situation (i.e. alcoholics). Eliminate (B).

If the theory can be successfully applied to alcoholics, it isn't outdated. Eliminate (C).

Again, since the theory can be successfully applied it isn't "fallacious" (i.e. it isn't "wrong"). Eliminate (D).

We don't get much context on the development of the theory itself. Was it a radically new and "revolutionary" theory? Or did it build on similar theory in a way that wasn't really revolutionary? The author doesn't tell us.

So, since we have no reason to believe the theory was revolutionary, we can eliminate (E).

That leaves us with (A), the right answer.

I hope that helps!

This is one of the longest passages I have encountered in GMAT practice questions. Though learners are getting long passages these days - perhaps rarely of this length - but still about 350 - 400 words.
