In study Ⅰ, the developmental changes of 4-9-year-old children’s ability-judgment under social comparison and autonomous comparison information were investigated by an experiment.
Recently, western psychologists primarily explored how children utilize social comparison or autonomous comparison information for ability-judgment, though several questions were needed to further explored.
On the stability analysis of large-scale systems by Lyapunov functions, it is necessary to determine the stability of vector comparison equations. For discrete systems, only the stability of linear autonomous comparison equations was studied in the past. In this paper, various criteria of stability for discrete nonlinear autonomous comparison equations are completely established. Among them a criterion for asymptotic stability is not only sufficient, but also necessary, from wh...
