Social hierarchy in preschool-aged children is stable and obeyed a linear relationship

(A) Experimental procedure for evaluating social hierarchy in children. The ranking between two children was tested by the bunny game twice consecutively in the first, third and fifth month. The blocking game was also applied to evaluate hierarchy in the first month. The teacher rating was conducted in both the first and the fifth month.

(B) Summary of social ranks defined by the bunny game for 54 groups of four preschool-aged children over a period of 5 months. Mean ± S.E.M.

(C) Possible social relationships among a group of four children and the percentage of each relationship observed (N = 54 groups).

(D) Correlation between ranks defined by bunny game and ranks by block-stacking game (Pearson Correlation, N = 216).

(E) Correlation between ranks defined by bunny game and dominance levels rated by teacher (Pearson Correlation, N = 216).

(F) Correlation between ranks defined by block-stacking game and dominance levels rated by teacher (Pearson Correlation, N = 216).
