Selelected in two stages.

Stage 1: Four happiness measures were administrated
- Satisfaction with Life scale

Scores were standardized and the z score for each individual were added. The highest and lowest 10% of standardized scores were selected on the basis of this distribution.

- Memory event recall balance
- Trait self-description
