In a study by Latané and colleagues (1979), participants were asked to clap or cheer as loudly as they could either alone, in pairs, in a group of four, or in a group of six. The researchers found that the sound generated per person was highest when people were clapping and cheering _ and lowest when they were clapping and cheering alone; in a group of six in a group of two; in a group of six alone; in a group of four in a group of six; alone

To analyze the findings from the study by Latané and colleagues (1979), we need to identify the conditions under which participants generated the highest and lowest sound levels per person while clapping or cheering. 1. **Highest Sound Level**: The study indicates that the sound generated per person was highest when participants were clapping and cheering in a group of two. This suggests that the social dynamics and encouragement from a partner may enhance individual performance. 2. **Lowest Sound Level**: Conversely, the sound generated per person was lowest when participants were clapping and cheering alone. This indicates that without the presence of others, individuals may not exert as much effort or may feel less motivated to produce sound. Thus, the correct interpretation of the findings is: - Highest sound per person: **in a group of two** - Lowest sound per person: **alone** This aligns with the social facilitation theory, where the presence of others can enhance performance in certain tasks.
