The present study investigated the effects of different levels of failure and different types of upward social comparisons on children's persistence. In this study, we used the "Impossible Task" to create a frustration experience and prompt peer achievement or effort to stimulate children's upward social comparison. The behavior data of persistence was collected through a self-developed game platform. Results showed that high levels of failure experiences significantly reduced children's persistence time; both types of upward social comparisons had longer persistence time than the group without upward comparison, but only the group of informing peer’s efforts had stronger willingness to continue in the future than the group without upward comparison. This study expands the exploration of factors influencing children's persistence and sheds light on the development of children's persistence qualities.
