The process that explains the behavioral change in Jerry is called a. Social interference.

Explanation:

Social interference is a concept derived from sociology and psychology. It explains that people are predisposed to perform less effort in a task if they work in a team instead of working alone. This means proposes that tasks under team circumstances seek to darg the skills of the group instead of pushing an individual's effort to achieve it, so it gives them the chance to not push themselves and work under forced labor.
