托福口语 Task 3

Social loafing is the tendency for individuals to exert less effort when working in a group than when working alone. This phenomenon occurs because people feel their contributions are less identifiable in a collective setting, leading to reduced motivation and responsibility. Social loafing can undermine group productivity and is more likely to occur when tasks are simple and group members do not perceive their individual input as crucial to the outcome.

Professor: Now, let me give you an example from a study I conducted with my research team. We asked participants to clap and shout as loudly as possible. First, each person did this alone, and we measured their noise level. Then, we had them do the same task in groups of six. Interestingly, when people believed they were in a group, they produced less noise per person. But here's the twist: we told some groups that their individual output would be recorded separately, even though they were clapping together. In those groups, participants clapped and shouted just as loudly as they did alone. So, the key factor was not the physical presence of others, but whether they felt their individual effort was being monitored. When they thought their contribution was anonymous, they slacked off—that's social loafing in action.
