Answer:
The aim in writing is always to write in complete sentences which are correctly punctuated. Sentences always begin with a capital letter and end in either a full stop, exclamation or question mark. A complete sentence always contains a verb, expresses a complete idea and makes sense standing alone. A complex sentence is a sentence that contains an independent clause and one or more dependent clauses. An independent clause can stand alone as a sentence, but a dependent clause even though it has a subject and a verb cannot stand alone. Here are some examples of complex sentences.

the answer is: A cognitive psychologist enrolls undergraduate students for a computer-based study about the effect of mood on problem-solving behaviors.

- The experiment should use studies or analytics to obtain some sort of private information from the subjects. (such as their mood)
- The experiment should make some sort of intervention that can be used to measure its hypothesis. (in the case above, the researchers could put the subject under a certain level of stress before telling them to solve a set of problems)
- The researchers need to interact with the subject in a certain way. (since the researchers meet the undergraduate directly, it's considered as an interraction)
Having positive relationships with anyone could help build a peaceful community for example:
You have a good relationship with your local grocery store worker, this makes the the workers job much more easier or enjoyable and your positive relationship with them will make them feel better therefor they’ll have a good day and the people surrounding them will also feel their positive energy which will multiply the amount of positive energy everywhere to ensure a peaceful community! Small things matter.

These rules are not set since they differ greatly depending on the culture and the society. In this example, Jessica showed exaggerated excitement when hearing about her friend's engagement. This is because according to the display rules these were news that should make her very happy.
