Nguyen can draw cause-and-effect conclusions from this research due to the fact that she conducted an experiment.

<h3>What is the effect of the research?</h3>

A subsequent correlation study would provide more information than Dr. Nguyen's study due to the fact that a correlation study would not only replicate Dr. Nguyen's results but would also be im[ortant in generalizing her findings.

If all mean differences are significant, there will be an effect of watching the news as there is an impact on the emotions.

In a situation where Dr. Nguyen used a measure of amygdala activation, she would have concluded that participants in the “Bad News” group will have higher than normal amygdala activity than the other groups due to the fact that the amygdala deals with negative emotions like fear or sadness.

If participants were from different cultures, in this case, the researcher might have been able to recognize the basic facial expressions of happiness, sadness, anger, and fear.

Which of the following happens when unemployed increases during a recession
Rina8888 [55]

Answer:

<em>I can see that there are no choices, so I'll answer the question according to my understanding.</em>

If unemployment increases during a <em>recession,</em> companies will continue losing<em> revenues</em> and<em> cash</em>. This can lead to a<em> halt</em> <em>of economic growth</em> and may eventually lead to many companies going bankrupt.

Explanation:

"Recession" occurs when the<em><u> spending</u></em><u> of the society declines.</u> This means that the<u> economic activity is also declining.</u> When this happens, companies start<em> laying off workers</em>. Many workers will then lose job. Company spending is also lowered, thereby affecting the economy of the country.

Once unemployment rate increases, people will <em>spend less</em> because they have <u>no money to spend on goods and services. </u>The<em> growth of economy will then stop </em>and companies will go bankrupt.

So, this explains the answer.
