Explanation:
Answer: Externalities are side effects (good or bad) that occur when a person or a company performs an activity and does not assume all the costs of it, or all the benefits that could be reported. In this way we can distinguish:
Negative externality: Arises when not all the costs of a negative effects are assumed. In these cases, a social cost is generated, since it is the whole society that suffers the consequences of its actions. And the market price does not collect this cost.
Positive externality: Arises from a positive effect that is not reported as a benefit. An example of positive externality that we can mention is scientific research, from which society in general benefits. In these cases, market place do not reflect the real benefits.
Answer: Experimental Method
Explanation:
The field of psychology has several research methods for the study of human behavior and its different forms. There is what is called experimental psychology, which expresses that psychological phenomena can be studied through the experimental method through observation, manipulation, and recording of the variables that affect the object of study.
The experimental method expresses that one or several variables are manipulated to determine their effect on an independent variable. In this case, rap music is set to see how it influences aggressive behavior and is analyzed because this type of music may have a certain relationship with the behavior.
In the experimental method, humans and animals are used to know the behavior that an individual may have when exposed to other variables that may interfere with their behavior. This type of experiment is usually done more in animals than in people because researchers can dispose of them at any time and in turn have more control. Besides, some experiments cannot be carried out in human beings due to ethical issues since if they are carried out they could put the person's health at stake.
The correct answer is this - <span>this research would not require IRB review because it would be eligible for exemption since the researcher is not interacting with the children and the playground is a public setting.
If the conditions were a little bit different, then his IRB review would also require different results. However, since there is no real interaction with the children, but rather only observation, an IRB review is not necessary in this case and can be avoided.
