The authors investigated the predictive utility of people's subjective assessments of whether their evaluations are affect- or cognition driven (i.e., meta-cognitive bases) as separate from whether people's attitudes are actually affect- or cognition based (i.e., structural bases). Study 1 demonstrated that meta-bases uniquely predict interest in affective versus cognitive information above and beyond structural bases and other related variables (i.e., need for cognition and need for affect). In Study 2, meta-bases were shown to account for unique variance in attitude change as a function of appeal type. Finally, Study 3 showed that as people became more deliberative in their judgments, meta-bases increased in predictive utility, and structural bases decreased in predictive utility. These findings support the existence of meta-bases of attitudes and demonstrate that meta-bases are distinguishable from structural bases in their predictive utility.
作者们研究了人们对自身评价是由情感还是认知驱动（即元认知基础）的主观评估的预测效用，这与人们的态度实际上是基于情感还是认知（即结构基础）是分开的。研究1表明，元基础在结构基础和其他相关变量（即认知需求和情感需求）之外，能独特地预测对情感与认知信息的兴趣。在研究2中，元基础被证明是态度改变作为诉求类型函数的独特方差的原因。最后，研究3表明，随着人们在判断中变得更加深思熟虑，元基础的预测效用增加，而结构基础的预测效用降低。这些发现支持了态度元基础的存在，并表明元基础在预测效用上与结构基础是可区分的。
