Compared with last year

It is including similar comparison, upward comparison and downward comparison.

社会比较可分为相似比较、向上比较和向下比较。

When the difference of the achievement was 20%,the participants would get the high levels of the behavior both in the upward social comparison and downward social comparison.

结果发现,成绩差异量越大,可达性越低;无论个体进行上行比较还是下行比较,当成绩差异量为20%时,其行为水平显著高于其他成绩差异量时的行为水平。
