Prior research has demonstrated that high processing fluency influences a wide range of evaluations and behaviors in a positive way. But can high processing fluency also lead to potentially hazardous medical behavior? In 2 controlled experiments, we demonstrate that increasing the fluency of pharmaceutical drug names increases drug dosage. Experiment 1 shows that drugs with fluent names are perceived as safer than those with disfluent names and this effect increases drug dosage for both synthetically produced and herbal drugs. Experiment 2 demonstrates that people chose a higher dosage for themselves and for a child if the drug bears a fluent (vs. disfluent) name. Using linear regression based mediation analysis, we investigated the underlying mechanisms for the effect of fluency on risk perception in more detail. Contrary to prior research, we find that affect, but not familiarity, mediates the fluency-risk link. Our findings suggest that a drug name's fluency is a powerful driver of dosing behavior.

先前的研究表明，高加工流畅性会以积极的方式影响广泛的评价和行为。但高加工流畅性是否也会导致潜在危险的医疗行为呢？在两项对照实验中，我们证明，提高药品名称的流畅性会增加用药剂量。实验1表明，名称流畅的药物比名称不流畅的药物被认为更安全，这种效应会增加合成药物和草药的用药剂量。实验2表明，如果药物名称流畅（而非不流畅），人们会为自己和孩子选择更高的剂量。我们使用基于线性回归的中介分析，更详细地研究了流畅性对风险感知影响的潜在机制。与先前的研究相反，我们发现，影响而非熟悉程度在流畅性与风险之间起中介作用。我们的研究结果表明，药物名称的流畅性是给药行为的一个强大驱动因素。（《心理学文摘数据库记录》 ）
