The rationale of this study is that scalar adverbs are likely to act as a convenient means to achieve cognitive closure because they stress the argumentative orientation of the message. Based on this assumption, an experiment shows that the introduction of scalar adverbs in the message decreases the extent of its cognitive elaboration and increases its perceived quality and effectiveness for people high in need for closure, but not for people low in need for closure, for whom the outcomes are reversed with regard to perceived quality and persuasiveness of the message. To what extent such outcomes are likely to be affected by some variables traditionally studied in the persuasion literature is addressed in the discussion.

强烈的论证导向使认知闭合更容易：有说服力的健康信息的案例

这项研究的基本原理是，标量副词可能是实现认知闭合的便捷手段，因为它们强调信息的论证方向。基于这一假设，一项实验表明，在信息中引入标量副词会降低其认知阐述的程度，并提高其对高度需要关闭的人的感知质量和有效性，但对于低需要关闭的人则不然，因为在信息的感知质量和说服力方面，结果是相反的。讨论中讨论了这些结果在多大程度上可能受到说服文献中传统研究的某些变量的影响。
