  1. Notes: Only one representative measure of each behavioral or environmental assessment is shown in this table. The sample sizes of the behavioral and environmental assessments are different across measures because only qualified participants are included in the statistical analysis. The effect sizes for categorical variables are evaluated by Φ and those for continuous variables are evaludated with Mann–Whitney and Wilcoxon nonparametric tests using r. Cohen’s guidelines for effect size are that a large effect is >0.5, a medium effect is between 0.3 and 0.5, and a small effect is between 0.1 and 0.3
  2. BDI-II beck depression inventory II, BMI body mass index, BTG-ACC the total correct rate in the ball-tossing game, CTQ-EN the emotional neglect score of childhood trauma questionnaire, CVLT II-Total score the total number of correct recalls over the five learning trials of the word list A in the version 2 of the California verbal learning test, N-back-CR the correct rate of the 3-back task in the N-back task, No-Go-CR the correct rate of the No-Go task in the Go/ No-Go task, ROCFT-DR score the score of delayed recall of the Rey-Osterrieth complex figure test, SDMT symbol digit modalities test, TPQ-NS novelty-seeking of tridimensional personality questionnaire, UG-AR the ratio of participants who accept the 1:9 allocation schemes in situation 1 of the ultimate game. In this situation, if the participant accepts the plan, the proposer and the participant will divide the money according to this plan. If the participant rejects the plan, neither of them gets the money
