This sentence would probably be a citation in APA style. Citations on research papers are very important since they give due credit to the original owner of the statement. Statements that don't have citations tells the readers that those statements are of the researcher/s alone which would be a problem for them if found out that it wasn't theirs to begin with. This would result to a work of plagiarism which is a grave sin in constructing research papers and is more equated with the act of stealing.
<em>Laughter can play a helpful role in MANY things, especially medical treatment. The reason it plays such a helpful role is because it makes people feel more happy and tends to take someone's mind off of what is going on around them. Once laughter is applied during a medical treatment, it is done to make someone feel less worried about what could be going on around them or how the treatment may go. This is commonly used by surgeons and kemo-therapy doctors when a patient is worried about what may happen.</em>
