Answer: At first, no one took Monroe's doctrine outside the United States seriously.
Explanation:
The Monroe Doctrine is the cornerstone of American foreign policy, setting out certain authorities' views on the Western Hemisphere and the colonies. Given that the position was expressed when the United States did not significantly influence the world, no one took the government's positions seriously. During that period, caricatures were even made at the expense of the United States' foreign policy, which ridiculed the authorities' inability to implement the Monroe Doctrine. Yet as the United States strengthened, the world understood the Monroe Doctrine. That happened especially after the American-Spanish war when the United States crystallized as a world power.
Answer:
The correct answer is letter c. a variable-ratio scheduled.
Explanation:
Psychologist B. F. Skinner developed operant conditioning, which is a method of teaching someone a desired behavior by reinforcing that behavior either positively or negatively. A positive reinforcer happens when something is added to increase the probability of a behavior. A negative one happens when something is removed to increase the probability of a behavior. <u>
The reinforcer is presented ONLY if the subject responds with the targeted behavior, but that does not mean every time the subject responds he will receive reinforcement.</u>
<u>A variable-ratio schedule is a schedule of reinforcement in which the person is not rewarded every time. As a matter a fact, behavior is reinforced after an unpredictable number of responses.</u> Because it is unpredictable, people are often more persistent, since they know they will eventually get the reward. That is the case with Shaquille. The basket is the reinforcement of his shots, but he does not know when he will make them. So he tries harder.
