Final answer:
Social loafing is the reduction in individual output on tasks where contributions are pooled, and it is likely to happen when individual efforts are not recognized.
Step-by-step explanation:
Social loafing is the tendency to exert less effort when working in a group because individual efforts are not recognized or evaluated. This can lead to a decline in performance on easy tasks. Research has shown that social loafing is more likely to occur in larger groups and among college students. However, social loafing can be alleviated if individuals know their work will be assessed by a manager or instructor.
