Note: In this study, multiple tasks were used in some dimensions to assess the same concepts. Due to adjustments made throughout the experimental process, it is possible to find different versions of tasks. In particular, for the assessment of social preferences, both a 3-question and a 6-question dictator game version have been used. Similarly, for the measurement of honesty, the picture difference task was predominantly used, occasionally substituted by the numerical difference task. For the evaluation of creativity, the brick task has been the main measure, although the rope task has been used alternatively in some sessions. In addition, for strategic thinking, the Uno game was used initially, followed by the piggy bank game and finishing with coordination games. Detailed information can be found in the Repository.
