What was the difference between the experimental group and the control group in Hanel's study?

• A. The experimental group wrote about personal values, while the control group wrote about a drink
• B. The experimental group wrote about personal values, while the control group wrote about a snack
• C. The experimental group wrote about the group task, while the control group wrote about a drink
• D. The experimental group wrote about personal values, while the control group described a beverage

Answer: (A)

The main idea is to see whether focusing on personal values changes the outcome by comparing it to a neutral task. In this study, the experimental group wrote about personal values, while the control group wrote about a drink. This setup keeps everything else constant (time, writing activity) so any difference in results can be attributed to the value-focused thinking, not to just writing or to something else like hunger or mood. A neutral beverage task provides a clean baseline, whereas using a snack or a different topic could introduce additional variables that muddy the comparison.
