What ethical questions does psychological research raise?

Answers

Earlier in psychology history, many experiments were performed with highly questionable and even outrageous violations of ethical considerations. Milgram's infamous obedience experiment, for example, involved deceiving human subjects into believing that they were delivering painful, possibly even life-threatening, electrical shocks to another person.

These controversial psychology experiments played a major role in the development of the ethical guidelines and regulations that psychologists must abide by today. When performing studies or experiments that involve human participants, psychologists must submit their proposal to an institutional review board (IRB) for approval. ​These committees help ensure that experiments conform to ethical and legal guidelines.

Ethical codes, such as those established by the American Psychological Association, are designed to protect the safety and best interests of those who participate in psychological research.1

 Such guidelines also protect the reputations of psychologists, the field of psychology itself and the institutions that sponsor psychology research

I have a test coming up for APUSH so f anyone could help that would be greatly appreciated!!!

Answers

Answer:

B) William Penn's careful planning and his policy of selling land to the settlers

Explanation:

William Penn was the founder, owner and governor of the Pennsylvania Colony. He received a British crown grant to establish a colony as payment for a debt that the royal family owed to his father.

Upon arriving in America, Penn had a very well done and meticulous plan to venerate land to the settlers who were interested. For this, he knew that Pennsilvania could not present conflict with the natives and for that reason he started a series of purchases from the territories of the Delaware Indians, who received a payment in exchange for the territory. Once free from the natives, he started selling land and it was a very promising and successful business.

1. Summarize the author’s argument and supporting evidence. 2. Why was Portugal successful in Asia? Be sure to amplify the author’s argument as you explain your answer.

Answers

Answer:

1.In the text, the author argues how the Portugal Empire came to be. He informs the reader of how the time that Portugal came into the picture was beneficial to them. It was favorable for them because no one noticed them due to the other countries being too busy doing their things such as fighting wars, fighting for power, controlling their people, and more.

Another reason is that they made allies and exploited local rivalries. The author tells of two competitors that were pretty clear allies and rivals.  These two cases were the conflict between Melinde with Mombasa and Cochin with Calicut on the Malabar Coast.

The third reason is that by them being so close to the ocean, it gave them a great advantage. The arrival of Portugal got looked over by countries more onshore because they were more concerned about what was happening on the landmass. China closed its trading ports, so they didn't want to bother with Portugal. Finally, Asia ignored them until Portugal was too established.

2.Portugal was triumphant in Asia because they were the first European country to launch the age of exploration. It was Portuguese sailors who first sailed from Europe to Asia by circumnavigating the African Continent. They used new technologies and new ideas to find Asia, and they continued bringing new ideas to the table once they settled.

Portugal was also successful because it had the economic and political rationale to establish colonies in places that were deemed desirable for their general potential for economic development and trade. We can see this still today because former Portuguese colonies like Macao and Goa are among the most developed areas in all of Asia.

Hope This Helps!!!!

Portuguese seafarers were the first to circumnavigate Africa on their way from Europe to Asia.

What are the reason for Portugal successful in Asia?

They formed allies and took advantage of regional rivalries, which is another explanation.

The author describes two adversaries who were quite obvious partners and foes. These two trials were disputes on the Malabar Coast between Melinde and Mombasa and Cochin and Calicut.

The fact that they were so near the ocean is what made them so advantageous. Countries closer to the coast ignored Portugal's entry because they were more focused on what was happening on the continent.

China decided not to worry Portugal after closing its trading ports. Asia eventually disregarded them until Portugal became too powerful.

Therefore, Portugal established its empire. He explains to the reader how it benefited them when Portugal entered the picture.

C) resulted in observable effects

D) proved difficult as the goats retreated to areas that were challenging

E) resulted in noticeable improvements in the park's environment

Therefore, this version of the sentence provides sufficient evidence to reinforce the argument that the goats’ relocation would be beneficial to the park’s environment; it asserts that a previous attempt to remove the goats resulted in noticeable improvements to the park region. This version follows very effectively from sentence 10.

In the 1980s, a brief attempt to relocate the goats was met with public outcry because E. it resulted in noticeable improvements in the park's environment.
