Answer:
- social loafing
- social facilitation
Step-by-step explanation:
Social loafing refers to a psychological phenomenon where individuals will work less when they are part of a team because they believe that someone else will finish the work for them. E.g. a teacher assigns a task to be carried out by a group of four students, it is normal than 1 or 2 will work very little while the others finish the assignment.
Social facilitation is another psychological phenomenon where individuals will work more because they know someone is controlling their individual performance, or they are competing against other people to finish an assignment. E.g. following the previous example, the students that did not participate in finishing the assignment will study for the test since the test is taken individually not in groups.
