    <p>现在实验进行完毕，你还需要填写一份实验后问卷，并有机会从中获得更多的实验点数。</p>
    <p>完成问卷后，我们会向你反馈你在实验部分以及问卷部分获得的总报酬。</p>

<p><strong>1.请在下方所列的10种情景中对选项A和选项B进行选择。</strong></p>
<p>如下的第1个决策情景，假如你选择选项A，则有10%的概率获得5个实验点数，90%的概率获得4个实验点数；假如你选择选项B，则有10%的概率获得9.625个实验点数，90%的概率获得0.25个实验点数。其他决策情景类似。<strong>区别是，从上到下，两个选项中获得更高收益的概率增加。</strong>事实上，
    在最后一行的第10个决策情景中，两个选项的收益不再具有不确定性，你仅需要选择获得5个实验点数还是9.625个实验点数</p>

<p>在你提交你的选择后，<strong>计算机会以相等的概率随机从10个情景中抽取出一个，并根据你在该情境中的选择来计算报酬。</strong>比如，计算机抽取的是第9个情景，如果
    你在这个决策情境中选择选项B，那么你将有90%的概率获得9.625个实验货币，10%的概率获得0.25个实验货币。</p>

<p>（注意：这10个情景你可以都选择A，也可以都选择B。一旦你从选项A转到选项B，电脑会自动地帮你把后续的选择都填成选项B。）</p>
