Email: vz29@cornell.edu Abstract Two well documented but still neglected blind spots of often-used study designs limit a researcher's ability to make inferences about psychological phenomenon. First, typical designs focus on effects of conditions at the group level and are not able to assess the extent to which effects characterize each participant in the study. This blind spot can lead to erroneous (or incomplete) conclusions about the effects of manipulations both for a given participant and at the group level. Second, commonly used research designs often use a limited sample of stimuli, constraining conclusions to the particular stimuli. This blind spot can lead to non-replication when different stimuli are used. We propose that the Highly-Repeated Within-Person (HRWP) approach helps mitigate these limitations. Using a study on the effects of anti-smoking messages, we illustrate how the HRWP approach helps alert researchers when the conclusions at the group level may not apply to all (or any) participant, quantifies the heterogeneity of effects of manipulations across people, and increases confidence regarding the generalizability of the effects. We discuss how the HRWP approach may help conceptualize issues of replicability in a new light. DOI: 10.1111/spc3.12487

解决常用实验设计的两个盲点：高度重复的内部人员方法

通讯Vivian Zayas，美国纽约州伊萨卡市康奈尔大学心理学系，美国14853-7601。电子邮件：vz29@cornell.edu摘要经常被使用的研究设计有两个有据可查但仍被忽略的盲点，这限制了研究人员对心理现象进行推断的能力。首先，典型的设计侧重于群体水平条件的影响，而无法评估影响表征研究中每个参与者的程度。这个盲点可能导致关于给定参与者和小组级别的操纵效果的错误（或不完整）结论。其次，常用的研究设计经常使用有限的刺激样本，从而限制了对特定刺激的结论。当使用不同的刺激时，该盲点可能导致不重复。我们建议高度重复人员内部（HRWP）方法有助于减轻这些限制。通过对反吸烟信息影响的研究，我们说明了当小组水平的结论可能不适用于所有（或任何）参与者时，HRWP方法如何帮助研究人员警惕，量化了整个人的操纵效果的异质性，以及增加了关于效果的可推广性的信心。我们将讨论HRWP方法如何以新的视角帮助概念化可复制性问题。DOI：10.1111 / spc3.12487 量化了整个人的操作效果的异质性，并增加了对效果的可概括性的信心。我们讨论HRWP方法如何以新的视角帮助概念化可复制性问题。DOI：10.1111 / spc3.12487 量化了整个人的操作效果的异质性，并增加了对效果的可概括性的信心。我们将讨论HRWP方法如何以新的视角帮助概念化可复制性问题。DOI：10.1111 / spc3.12487
