Abstract: Adopting the materials in the Treisman′ experiment named ″illusory conjunction″, the accurate rate and the reaction time were analyzed as the index of the levels of the behavior. The study tried to explore the effects of the different direction of the social comparison and the accessibility of the comparison target on the operate level in the cocation. The results showed that the main effect of the difference of the achievement was significant(the difference of the achievement was more, the accessibility was less). 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. The difference of the achievement of the rate of the conjunction accurate was: 20%、30%、10%、40% in the upward social comparison, and the difference of the achievement of the rate of the conjunction accurate was: 20%、10%、30%、40% in the upward social comparison. The participants who were in the upward social comparison were significant more intense than the participants who were in the downward social comparison.

Key words: upward social comparison, downward social comparison, accessibility

摘要： 采用“错觉合取效应”实验材料,以正确率和反应时为行为水平的指标,探讨在coaction的情景下,不同的社会比较方向及比较目标的可达性对个体任务操作水平的影响。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。上行比较时,不同的成绩差异量,任务操作的正确率由高到低依次为：20%、30%、10%、40%;下行比较时,不同的成绩差异量,任务操作的正确率由高到低依次为：20%、10%、30%、40%。对个体心理紧张度进行方差分析发现,当个体进行上行比较时,心理紧张度显著高于下行比较。
