Replicating Latané's classic experiment, students are asked to clap and shout as loudly as possible. Half perform alone; half in groups of six, believing the group's combined output is measured. Per-person sound output drops by roughly 30% in the group condition, even though all participants insist they exerted full effort.
The drop in per-person output most clearly illustrates:
- A
Conformity to group norms
- B
Social facilitation
- Ccheck_circle
Social loafing
- D
Bystander effect
Explanation
When individuals' contributions cannot be evaluated, they reduce effort on additive tasks—the textbook definition of social loafing.
